Youll notice you have some more options now. Making child rooms is an advanced and powerful feature, but outside the scope of this tutorial, so just drag it into the position above the room "rm_game", as shown in the animation above for now. In this room, we are going to create a new layer specifically for our enemy instances, so create a new layer now (click on the New layericon ) and name this layer EnemyLayer. The First No matter how you set things up, if you don't enable views then nothing will change, so this is very important! Open this up and youll see a grid and a Room Editor. Again, like the Set Fontaction, this will set all further drawing to use the given colour (and not just for text either, this will affect shapes that are drawn and few other things), and so can be called once at game start if the colour isn't going to change, or once every time that you want to draw with another colour. Now we need to add events to let our character move. We then reset the alarm to the spawn_rate value so that it will count down again and spawn another one. To get started with GameMaker Studio 2, first create a new project. This will scroll the layer by the number of pixels given every game frame, so setting a horizontal speed of, for example, -2 will scroll the background from right to left at a rate of 2 pixels every game frame. This needs to come from your Sprites folder, so make sure to drop the image in there first. In this case we will simply edit the default room "room0". You'll see that we have the option to Stretchthe background image too. Play your game again now and note how the sound changes every time you destroy an enemy. This is a great method to add more life to your games and can be applied to almost any repetitive sound effect to make it more interesting and realistic. The Sprite Editor will now look like this: The top part of the editor will show a single image, and the main window will have a larger preview. Now, lets draw something simple to represent our character. creating a prototype around that idea For this we need to add a Create Eventfor the object "obj_player", and in it add the following action: All we are doing here is preparing a variable called "cooldown" for use later on in the game - remember, the Create Event is only run oncewhen the instance is first created, so this variable is being initialised to 0 once only. tutorial_game_files.zip Notice that when you reorder the rooms there are actually two different places where you can drop the room when you click and drag. Now add a Create Event: We are going to have our object draw its sprite fading in gradually, just to create a slightly nicer looking title screen. Create Object. In this case we are going to change the alpha to make the sprite "invisible" at the start of the room. to You can now select the Instanceslayer and then in the actual room editor workspace, use / + to select all the enemy instances one at a time. By default GameMaker Studio 2will use a draw colour of white for everything, but at various points in your game you may wish to change this, and it's good practice to explicitly set the draw colour before drawing anything, so that is what we are going to do now as well as draw the text itself. Create You don't even have to worry about placing it properly because we've taken care of that in the Create Event of the object. Change the dropdown menu right above the preview of the sprite from We have set the direction so now we use this action to set the speed to the variable we defined in the create event. Throughout this tutorial we will build a small "arena shooter" - a top down action game with a player, some enemies and lots of bullets. Rooms free game engines The following image is a schematic representation of how layers are rendered to help you visualise what's going on: In our tutorial game, we have just set the bullet instances to use the same layer that the instance of "obj_player" is assigned to by using the layer name "Instances" from the room editor. Since it doesn't have a sprite it will be shown with a question mark icon . Make a new sprite, and fill it with red to make a 3232 red box. ). x Let's see how that works in practice by adding an action As mentioned above, the Step Event is run each and every game loop, so anything we put in here will happen once per game frame (30 times in a second for a 30 FPS game, 60 for a 60fps game, etc). This means that the action is going to work on a different object (in this case we have selected obj_scoreas the object to target). It is expected that you know some coding basics (like what a variable is), as this tutorial wont go too in-depth into how the code works. Go back to the controller object obj_scoreand make sure you have the general Draw Event open as we need to edit it. obj_damage obj_player We will explain what each resource type is as we come to it in the tutorial, but we won't be covering all of them. spr_player Sprites are the game dev word for images. As were using Drag and Drop, we can add our game logic simply by choosing commands from a toolbox. Go back to your damage object and change the code so it looks like this: I know we said we would be controlling time, but controlling the speed at which the box moves is much like controlling time, and its a lot easier. This makes GameMaker ideal not only for beginners but also artists and designers that want to build games without learning to code. Our tile set is now set up and ready to add to a room We need to go back to the Room Editorworkspace now, as we want to create a new layer called the Tilemap Layer. We have set the direction so now we use this action to set the speed to 16, which means it will move 16 pixels in the given direction every game frame. spr_player Step event will run only once, right when the object is created. Now that its the right size, lets draw on it. To create the object, right click Login to SAP GUI application. In this case we use view port[0] since that is the one we set up in the room editor in the last section. Note that we are not setting the "speed" value directly, but instead will be using this custom variable to set the speed. We now get to see an section section Now, go ahead and press x yet. Instead, it teleports back up to the top of the screen when it reaches the bottom. Its really important to type everything exactly when youre writing code. If you now run the game again, you'll see the player instance move off to the right: We now have some movement, but it's not very much fun for anyone let's now add some new code to the player to make it respond to the user pressing the arrow keys on the keyboard. , youll see we have a default starting room for our game. One of the benefits of GMS 2 is that it doesnt require a bunch of scattered dependencies to make it work. Thats because we havent given them anything to do, so they just stand where weve placed them. Tile Sets are always comprised of a single sprite image, and must always be based on a grid, although the grid does not have to be square, just regular, ie: you can have 24x96 tiles, or 32x32, etc as long as each part of the tile set image is on a grid it can be used in GameMaker Studio 2as a tile set. Note that if we want to go to a specific room without following the order of the resource tree, then we would use: The Room Gotoaction lets us go to any room in the resource tree (you can press to open the manual and see what all the other room actions are). Now you should be able to slow time by pressing A and speed it up by pressing D. Congrats! So, if you hold down A for one second time will increase by 0.6. Type the following: Type Carefully! You made a test project that does something! bottom center Next we need to add a Step Eventwith the following actions: All this action block is going to do is add a small amount to the image_alpha value and then check it to see if it is over 1, and if it is it resets it to 1. We will be using an However before we get to that, you should fix the tilemap layer so that it covers the whole room: To prevent the issue with the huge window we need to tell GameMaker Studio 2to only show a portion of the game room using a camera view. The final game will look something like this: We will be keeping the tutorial as simple as possible, with the idea being to give enough of an overview of how things work for you to get stuck in and making your own games as quick as possible. Step Debugging is no fun, so try to copy the code exactly. GameMaker Studio 2bases all the scale on factors, where a factor of 1 is 1:1 with the original sprite image, so a factor of 1.5 is 150% bigger and a factor of 0.5 would be 50% smaller. Its a flat purchase price, meaning that GMS 2 doesnt try to take your games profits or make you pay monthly. manual Youve made a (hopefully) functioning prototype for a new game. is the exact point that the game considers your player to be. You can have multiple view ports active in a room (up to 8, starting at 0, so it's view_camera[0 7]) and can assign a camera to each one, so referencing (for example) view_camera[3] will mean you are dealing with the camera assigned to view port[3]. Lets make a new GameMaker Language vs Drag and Drop setting is pretty smart, and it does a good job, so I wont change it for my sprite. , select You can change this value if you wish, but by default it's locked and handled by GameMaker Studio 2automatically. The goal of this step is to make a simple game to test if it will even work. Now hold down / + Cto copy them and then / + Vto paste them. to zoom it in and out. on resource name and call the room "rm_game". If you click on the Play button at the top of the screen, you can test out what youve built. Go ahead and run your game again. In this case our controller object won't be drawing a sprite but it will (by the end of this tutorial) draw some text and manage the player score value and certain game events. spr_player To add a background to our game we want to use a Tile Setresource. Create something similar of your own and then drop it into the Sprites folder. So what we need to do is draw the score text relativeto the view camera. As you may expect, the collision event runs its code when the two objects collideor, more precisely, when their bounding boxes touch each other. If the object is in the room when the game starts, this code will run once when the game starts. So, if you want something to appear above or below something else, it should be placed on an explicit layer. Click the small box with four arrows under Sprite However, if you have zero coding experience, you should still be able to follow along. global. Now your player object is in your room, and therefore part of the game. We are going to use alarmsin this object to create instances of our enemy spawn object within the room, so to start with add the following Actions into the Create Event: The first action sets a variable to control the speed at which enemies will spawn. "Career Karma entered my life when I needed it most and quickly helped me match with a bootcamp. stores something for us, like a number, so we can use it somewhere else. statement: To break down the code a little, first we check if time is below 1. Before joining the Career Karma team, Scully worked in IT support, graphic design, and as an editor for Cambodia's Khmer Times. We want the bullet to shoot off in the direction of the mouse, so we need to add the following actions: Adding these into the Create Eventof the bullet object should give you this: Go ahead and hit Run now to see what happens: That's starting to resemble something that could be called a game, but there is an issue because we are creating the bullets on the same layer as the player, they are being drawn on top of the player which doesn't look right. These dictate how close to the edge of the view the instance needs to be before the view camera will move to follow it. Its fortunate then that there are many other options available, such as the excellent GameMaker Studio 2. obj_damage We want to now make the player instance move when the user presses the Arrow Keyson the keyboard. When it comes down to it, the best game engine is the one that youre most comfortable with and that allows you to create what youd like to create. His relationships with coding bootcamps give him particular insight into these new job training programs. Return to our player object and add a new event; but this time, go to So we can't write: That code will subtract 1 from ANY of the instances of "obj_enemy" in the room, and so is best used when we know that there is only one unique instance to be accessed. Youll now be greeted with a Workspace on the left and an asset browser on the right. With a simple idea in mind, its time to which will be a completely empty object with physics once again disabled. we now have a nicer introduction to the game. this video has not coding. Happy developing! is also accompanied by a short video that takes you through each of the steps outlined in text, and you can close GameMaker Studio 2at any time in the progress of this tutorial (saving your project) and when you next load the project you will be taken to the place where you left off. GameMaker Language vs Drag and Drop GML, or GameMaker Language, is GameMaker's proprietary programming language. Note that the top left corner of the tile set sprite is empty. To do that, let's first change the Step Eventaction Instance Createof the object "obj_player" by simply changing it to use the player position (x / y) instead of the mouse position (mouse_x / mouse_y): Once you have made that change, we need to switch to our object "obj_bullet" (double click it in the resource tree, or use / + to bring up the Workspace Switcher). The top left square is always the empty image. In the Scoring Sectionwe explained how GameMaker Studio 2default draws the sprite assigned to an instance of an object, and most of the objects in this game have no Draw Event. . So you can have a camera view that is 480x320 (for example) but make the camera port 960x640 and the camera view will be scaled up to fit. To start with lets name the tile set "tl_background" and assign it the sprite we just created. This is done using the following actions, which you should add in after the current ones: The next thing to do is to make the "hp" variable actually go down, as currently that check will always return false since we only set the "hp" to 5 and nothing else. The action can be found in the Mouse and Keyboardsection of the action toolbox and you should drag it into the action workspace abovethe Assign Variable action: Note that when you drag it near the existing action an area will be highlighted indicating that it can be placed either above or below the action in the chain (in the image above we place it above), and once you drop it you will see that it is connected to the Assign Variable action like this: That square chain on the left means that the "if" action will be called and thenthe Assign Variable action, but that they are independent of each other. You can delete it, and you can edit it, and you can create further rooms using the right button When you drag this into the action workspace you then have to click the little arrow to the right and select a "target". The next step in our GameMaker Studio 2 tutorial is where things start getting really fun. F5 We are going to expand on the current actions to include a check to see if the "hp" variable we initialised previously is less than or equal to 0, and if it is we are going to destroy the instance (remove it from the game room). All instances have some built-in variables, of which "x" and "y" are perhaps the most important as they set the position of the instance in the game room. You can resize these objects by simply grabbing an edge and pulling. This will only run once, and well use it to establish a global variable. Lets add some finishing touches. Well, so far we haven't added anyDraw Event to anyof our instances, and yet they all draw their sprites to the screen when we run the project. This will trigger whenever the key is down, which also means the player will be able to simply hold left or right (rather than needing to tap the button). If you set this in the room editor you won't see anything happen, but in your game it will scroll. engine made for 2D games GML Code GML Visual. For example, many people will name their objects drop-down in the resources panel and click we spent some time showing how to add text to your game and increment the score, which shows the player how well they are doing as they play. Now, when you adda general Draw Event to an object and in it add some action blocks, you are telling GameMaker Studio 2that youwant to handle what is being drawn and GameMaker Studio 2will no longer draw anything except what you have put in the event, so it won't draw the assigned sprite unless you tell it to (and you can draw any sprite, it doesn't have to be the assigned one). However, it is most commonly known as GameMaker Studio 2.. Objects will be used for almost everything in your game, from the Player, to the enemies, to the bullets and explosions, and you can define how they behave and react by giving them code. If you run the game at this point, you will find that you now get a massivegame window that is way to big for most people to actually play in, so we need to sort that out using cameras. Workspace Before you try it out, dont forget to drag your world object into the room with your box and player. Now, we can attach the sprite to our character object, and put that object into our room. Also I'm not a graphic artist, so how about graphic elements to use, like in RPG Maker? You then made it move around with the arrow keys, and always rotate to point at the mouse position. Now set the tile width and height to 32.. Thats because it doesnt have a Now, you may notice that they dont do anything. Were going to use the one we just made. Let's go ahead and create our first sprite resource. . For now, we will just leave it set at default with the room taking up the whole game window. In our Step Eventaction workspace, we need to add the following action at the end of the current list, if mouse down(from the Mouse And Keyboardaction library): This action functions just like the if keyboard downaction and performs a conditional check to see if the left mouse button is being held down (remember, "if" conditionals check for a true or a false return value) and the subsequent blocks we add will be within this conditional and should only be run if the conditional returns true - essentially, the mouse button is being held down so do something. Next we need another variable for the speed we want the enemy to move at: This variable will be used to define the movement speed of the instance. You can also set the the camera view port, which is what defines the area of the screen that will be used to display the camera view. , go to The code we just wrote will constantly check if youre pressing the left arrow key on your keyboard. For that we'll use the following image in this tutorial, but you can create your own if you want: You need to click on the button to begin making your first game. at the players feet. To create the player, right click no the Objects folder in the Assets Browser and create a new object. While Android Studio is a powerful IDE and comes with many additional tools for development, it is primarily suited to productivity apps and tools and has a steep learning curve. When you have multiple resources open you can also use Playing a sound is really simple and requires a single action, the Play Audioaction from the "Audio" library. GameMaker Studio 2 Note: This is ONLY to be used to report spam, advertising, and problematic (harassment, fighting, or rude) posts. GMS 2 isnt free, unfortunately, but its still an excellent tool thats relatively cheap for a high-quality game engine. Currently, if you destroy the enemies without getting hit, then the game doesn't do anything and the user has to close the game window. Follow our beginner tutorial series and you'll be making games in no time! If you have any issues, you can also find the images here. This little chap is called Bee Boo.. We need to go back to our object "obj_player" and change the creation code to look like this: As mentioned previously, you can use the layer name (in "" as a string) to tell GameMaker Studio 2what layer to use, and now if you test the game again, the bullets will be created below the player object. Right now, nothing happens; weve got a bit further to go before this GameMaker Studio tutorial is through! section By the end, youll have built your first 2D platform game! We do this because we will often have to mention the names of things in our code. After youve downloaded the game development program, you should be ready to make a game. Learn more. Events Space These are the default layers created for any new room, where the background layer permits you to use a colour or a sprite for a single background image, and instances permits you to add instances in to the room. we will change that by making it more attractive to the player using tilesand also expand the play area using cameras. Origin At the moment, our bullets are created 1 per game frame (every time the game loops round and performs the Step Event again), which is a bit too fast for what we require. We covered how to add a sprite in the first part of this tutorial, so we'll only briefly run through the procedure here: If you have used the sprite that we used for the tutorial, you should be placing the origin near the bullet image "head" (as shown in the image below), as that is the point that we want to rotate it around and "pin" it into the room with. Collision Mask This is the equivalent of a scene in Unity. In this GameMaker Studio 2 tutorial, we will learn how to make a game by If you run the game now you can see how this all works to make the camera follow the player while they explore a larger room and shoot the enemies Getting to grips with the room editor is essential if you want to get the most out of GameMaker Studio 2, and there are many, many features to it. Your character should be able to move left now. Large triple-A studios start with a long design, concept, and prototyping process. Right now, unfortunately, our player object looks like nothing. Ive found that to be the best place when making a top-down game. GameMaker Studio 2still has the "score" variable for backwards compatibility, but it has been deprecated and should not ever be used. You should be familiar with how to do this so go ahead and make one now and call it "obj_score": The object "obj_score" will be our controllerobject and so we don't assign a sprite to it since we want it to draw other things (like the score text). Resource Tree In this case we want to assign the dark tile sprite we added, so click on the section marked
