drop-down in the resources panel and click that depends on what you're planning on making. In this case we are going to use a function to get the direction from the player instance to the mouse pointer and set the image_angle to that. A Note About Game Engines section Generally this is what you want for music or ambient effects like a wind or waterfall sample, but not for single sound effects like this. The For this, we are going to use another of the built-in variables that all objects have - the image_angle. The Key Up Event detects when a key has been releasedand won't trigger until that happens. download it here We now need to make a new Tile Setresource, which is done the same way as for sprites and objects, etc by right clicking on the Tile Set resource folder and selecting Create. Origin on the object in the resource tree and dragging it into the room where you want it to appear: We can actually run the "game" now as we have a room and an object so go ahead and click the Run Button section: With that, this tutorial is pretty much finished. Go back to the controller object obj_scoreand make sure you have the general Draw Event open as we need to edit it. To start with, drag an Assign Variableaction into the action workspace and position it abovethe Destroy action : We want to set this action so that it changes the "thescore" value in the object obj_score. Basically, some tile set images may be created with "empty" areas around each tile and so you can set the pixels or cells between each individual part of the image here. Preview Mask This is done from the background Layer Propertieswindow: The background layer is a layer that can be cleared to a single colour and/or have a single image applied to it. in this series will see us creating a new object for the enemy and having it react to the player and the player bullets You've made it to the Enemies Section of our "My First Game" series of tutorials, and you're doing well! Let's quickly cover the main points you should have picked up while going through this: Our arena shooter game is starting to look pretty good now, and we have all the essentials in there. . But to get into making our prototype, we just need something that tells us where our player is and how big they are. This is an arbitrary number that simply tells GameMaker Studio 2to play the sound "as is". We need to add a Create Eventto our bullet. This object will be for our player and is what will permit it to move and shoot in the game room. In GameMaker Studio 2the (0, 0) position is considered as the top left hand corner of your room and the horizontal axis is the x axis and vertical axis is the y axis: Run the game now (press y By doing this we are adding -1 relative to the current value, ie: subtracting 1 from the current value. First 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. That "do something" is create our bullet instance and then set the variable cooldown to 3 (using the actions Assign Variable), which means that the next game frame, the if variablecondition will failand no bullet will be created because "cooldown" is not less than 1. 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. . section of this tutorial You've made it to the Scoring Section of the "My First Game" tutorial and in this In this case we use view port[0] since that is the one we set up in the room editor in the last section. spr_damage Privacy Policy All objects are placed on layers, and when an instance is created in a room it must always be assigned to a layer, and the layer it is assigned to will affect the render order, ie: whether it is drawn "above" or "below" other things that are being drawn on other layers. Simply click the right mouse button on the Sprite resource and select Create: This will open the Sprite Editorwhere we can add an image and set certain properties for the sprite: To start with, you need to name the sprite. Being able to access variables in other instances is incredibly useful and very powerful, and it's important to know how and when it can be done. Be sure to follow the steps carefully. Now that we can move, lets make something that can hurt us, to provide a bit of a challenge for our players. In this case we are going to add an action to the event to make the player instance move right across the screen. We now need to add an image to the sprite to use as our player. However it's missing one or two things to take it from a prototype to a finished game, one of which is a scoring system which is what we'll cover in the next Well start with an F5 Going back to our game, if you press Run now then you can test our bullet creation actions: Hmmm That's not really what we want is it? To get started with GameMaker Studio 2, first create a new project. The first is dropping it onanother rom (the room being dropped on is highlighted), which means that you want the selected room to become a "child" of the other room, and the other is dropping it over a room (where a bar is highlighted above the room), which will place it in the room order. You can have multiple camera views in a room, and they can all be enabled and displayed at different positions (permitting, for example, a two player split screen game, with a camera view for each player), however for our game we only need one, and that's the camera View 0. When you build a game for real, youll probably want to use multiple sprites to create animations. If you select it then you'll see the event added into the Event Editor window and a new window chained to it: The new window is the DnD Editorand is split into three parts: The idea of Drag and Drop is simple - you select an action from the toolbox and drag then drop it onto the action workspace. Step 1. The play area for the game is a bit small so the next thing we are going to do is make the roomsize a bit bigger. You will learn a bit of code and a bit of game design as we go. We are going to edit this now to dynamically create instances of the bullet object as the game is being played. As were using Drag and Drop, we can add our game logic simply by choosing commands from a toolbox. Another caveat of GameMaker Studio is that it is not free, whereas the more powerful Unity and Unreal Engine are. This is done by going to the Layer Propertieswindow - which is opened by default on the left of the room editor when you select any layer - and then clicking the button that says "No Tile Set" which will open a window to let you select the tile set to use: The tile set selected will now open on the right of the room editor workspace and you can click on any of the tiles to select it for "painting" into the room: We now need to paint the tiles in a way that makes sense for the room and the tile set chosen, so select the appropriate tiles to make the final tilemap layer look like this: You can test the game now and it should play exactly the same as it did before, only now we have a nicer background for the action to happen on. We are going to make a new object and call it With this ease of use does come a slightly more limited scope. This controls the vertical position of our object, with the top being zero. Its fairly easy to use, and it emulates code pretty well. This score will then be displayed prominently at the top of the screen To keep things clear and easy to manage in our arena shooter project, we need to make a new object to act as our main "controller" object for the score. In this tutorial, we will walk through the start of that process together in a game Select the RFC_READ_TABLE module as the Function Module. If you dont, youll get an angry red circle on the left side of the code window, and an error when you try to run your game. Ive found that to be the best place when making a top-down game. So, the next Bounding Box Powerful. creating a prototype around that idea Each loop is called a game frameand so we call the speed at which a game runs the game Frames Per Second (FPS). variable controls the objects horizontal position on the screen, and its measured in pixels. Your character should be able to move left now. For example, many people will name their objects To open it for editing you need to double-click This variable controls the angle of the sprite assigned to the instance, so setting it to anything other than 0 will rotate the sprite (and its associated collision mask) by the amount given. The next action sets the alarm [0] to the value of spawn_rate. section We can now associate the sprite to the object by selecting it from the list of available sprites. Objects Learn more. Note that we are not setting the "speed" value directly, but instead will be using this custom variable to set the speed. However "other" in that context onlyworks for the collision event, and we want to apply an action to an instance in the Step Event, so we need to change the scopeof the action we are going to use. Switch back to the Room tab and then select the Instances layer in the Room Editor window. When ready, click the Play button to test your game and you should see that the enemies now scale into existence. . . Now, its time to code. For this we add the Set Instance Alphaaction into the Create Eventand set it to 0: We also want to make sure that the sprite will be drawn in the exact centre of the screen, so we need to add the Jump To Pointaction, from the Movementlibrary, like this: This action will set the instance to the position specified, and in this case we are using the globalvariables, room_width and room_height to get the middle of the room (half width and half height) for the instance when created. Essentially, the higher the depth, the "nearer" the camera it is and the lower the depth the further away, so a layer at depth -200 will draw under a layer with depth 300, for example. was equal to the number of pixels on the screen, our object would be at the far left. If the game detects that youre pressing left on the keyboard, it will run the code in the curly braces. I'm no programmer at all, so I would need to use the drag & drop mode. The Also I'm not a graphic artist, so how about graphic elements to use, like in RPG Maker? 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. This software have it's own language GML which is REALLY powerful too and easy to learn. This is necessary because the tiles themselves are in the Tile layer and dont have any impact on our game objects. yet. 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. Since weve just gotten the program, lets look over the interface. However, all drawingmust be done in a draw event, and in general placing draw functions in any other event will notwork. Now, go ahead and press Happy developing! The Im using sprites from an old greenscreen style game I made. section This is done by checking the box labelled View Visible. The main points you should have picked up while working through this On the right is the So, add a Create Eventnow, and in the action editor window that pops up drag the Assign Variableaction and set it to the following: This gives us an instance variable with the name "thescore" and sets its value to 0. There are different types of workspace too, but we'll cover that a bit more later. It then creates a starting point from which you can grow your project. . That said, for those that do want to add some custom logic, there is a GameMaker Language that affords slightly more flexibility. You have 12 alarm events and they can also be accessed using the built in variable array alarm[0 .. 11]. You can delete it, and you can edit it, and you can create further rooms using the right button When you start a game, you aren't normally just dropped straight into the action, but instead you are usually presented with some kind of title screen. If both of those are true, then we increase time by 0.05. This means that we now have to re-order the rooms so that the title room is placed before the game room. Sprite Finally we set the sprite rotation (image_angle) to face the same way as the direction variable. You can get quite far using the drag and drop system, but really it depends on what you want to do and how complex you want to design your project. Currently we are adding 4 to the "x" value every game frame, so what we want to do is only add 4 if the keyboard right arrow is being pressed. if The origin is simply a point on the sprite that will be used to position it within our game room, and you can set it by either clicking For now, we will just leave it set at default with the room taking up the whole game window. starting with an idea While that process is effective for large studios, it can bog down indie or solo developers. However we want to edit this as it is too large for what we need, which means you have to click the Modebutton and select Manual. Step If you have any issues, you can also find the sound here. if This means that it is created when you use the action and then discarded again at the end of the event or script that created it. That's not very satisfactory for the player! In the action above we will use the random_range function to give us a random value between 0.8 and 1.2 for the sound effect pitch, and so every time it is played it will sound slightly different. This should be set to 3232. Essentially, the general Draw Event defaults to using the Draw Selfaction . We use this event just to give the user a moment to get ready to play, as the other two key events would change the room instantly. What's happening? This is useful for many, many things, not least of which is storing one-off values from calculations and saving memory resources. This layer will be used to show the background tile sprite that we added previously. Having an enemy just appear out of nowhere would be unfair and annoying to the player! This will only run once, and well use it to establish a global variable. Finally, how powerful is this software? Before joining the Career Karma team, Scully worked in IT support, graphic design, and as an editor for Cambodia's Khmer Times. This area is the actual room, which is currently a blank canvas on which you can place resources to create your game level. 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). were to equal zero, our object would be at the far left of the screen, and if Now set the action as follows: Note that when using an object index like this, if there are more than one instance of the object in the room when the code is run it will run for all instances of the object. Go ahead and press We'll use this to change the calling instance (the spawner) into an enemy instance, so drag that into the action list now and set it to change into the object obj_enemy, like this: So, first we check to see if the scale is 1 (100%) and if it is we change the instance into a version of the instance obj_enemyusing the action Change Object Instance. An easy GameMaker Studio tutorial for beginners Next, we need to add our tiles. Dont capitalize anything that shouldnt be capitalized or forget to put any parentheses or brackets where they belong. https://www.yoyogames.com/gamemaker/featuresGameMaker Studio 2 is the latest and greatest incarnation of GameMaker! Else (otherwise), set the gravity to 0.5. Run your game again (press ) and this time the player instance should do nothing unless you press the right arrow key. To fix this, we need to add events to our player. Image Size That way, the user can move with the keyboard and aim and shoot with the mouse. in the name box. By default this is set to 30 by GameMaker Studio 2for any new project, which is fine for puzzle games, or games that don't require fast response times or even for mobile games, but for arcade style games like ours a preferred value would be 60. We need to "spice it up" a bit and one of the easiest way to do this is to simply change the pitchof the sound. event > collision > obj_damage You made a test project that does something! GML, or GameMaker Language, is GameMakers proprietary programming language. To move from one room - the title room - to the next one - the game room - we will need a new object, so go ahead and make one now (Right click on the object resource folder and select Create). The next step is to finally get into some code to make our character move around on the screen. Naming Practices With that done, you can go back to the game room and on the new EnemyLayerlayer add five or six instances of the object (click on the obj_enemyspawnobject in the resource tree and then drag it into the editor window and release the mouse button). But what are we going to set the rotation too? Yes you can. Drag and Drop This Right now, it doesnt actually affect timeits just a number. make your own game! we are going to dedicate to adding some sound to our game. This is going to be pretty simple code, so dont worry. section By default the room will have been created with a Backgroundlayer, so select that now. The idea behind an object is to create a kind of blueprint of behaviours that can then be used within a game. 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. anywhere on the preview image to set the origin to the mouse position, or using the drop down menu to set a fixed position for it: You can see that in the image we indicate Middle Centerso select that as the position for the sprite origin. A About the author: Ethan Scully is a writer, editor, and game developer who manages Career Karma's content partnership initiatives and is currently based in Istanbul. An event is simply an action or change that occurs within the room. It's also not a very big play area for the player to move around in, making the game feel cramped. Notice that when you reorder the rooms there are actually two different places where you can drop the room when you click and drag. It moves 50 pixels every frame, compared to your character that moves 5 pixels every frame. That was a good start, but it still wasn't a game, so in this tutorial we're going to add a shooting mechanic to the project. The first thing to do is to add a background. bottom center and then In this case we are going to make a sprite to represent our player. A Lets add some finishing touches. We need to change the actions to make the bullets fire from the playertowards the mouse, and not just magically "appear" where the player clicks. This is now an easy thing to fix, as it requires a simple change to the number of frames we wait between creating each new bullet instance. . The first thing to do is tell GameMaker Studio 2that we want to draw with new font resource, so before the Draw Value action we need to add a Set Fontaction like this: As the action name implies, this will set the font for drawing any text.
