we have added a simple sound effect to the game and made it a bit more interesting by changing its pitch every time it plays. Here's many tutorials on the internet and amazing manual. For this tile set you need to set each of these values to 128px. See also:How to create a simple 2D platformer in Unity Party One. Getting Started 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. Open the action editor in the Step Event(double click the event if it's not open already). we have added yet another object to our game, the enemy, and got things feeling a bit more like how an arcade game should feel. Thats because it doesnt have a Note that this will set it for the whole gameand all subsequent text will be drawn using this font even if you don't use this action anywhere else, so if you want to use various fonts in a game you must call this action before every item that needs drawing, but if your game only needs one font then you can call this action in a controller at the start of the game once only. However for our game we are keeping things simple and all those values can be left at their default settings. Otherwise the G-forces would prevent our player from being able to move! 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. Instead we need to first of all tell GameMaker Studio 2to change the "scope" of the following actions to affect the "other" instance in the collision using the action Applies To. 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! These functions will return the (x/y) position of the view and store each one in the temporary variables "cx" and "cy", and note how we use the previously declared temporary variable here. When ready, click the Play button to test your game and you should see that the enemies now scale into existence. We do this because we will often have to mention the names of things in our code. section. F5 which will be a completely empty object with physics once again disabled. Click on the Rooms folder in your Asset Browser, and youll see that you already have an asset called Room 1 in here. to run the game. The first thing to do is to add a background. From here, you can move on in the development process to more game logic, doing some pixel art (although, how could you improve on my masterpiece here? Sprites For that we need to add a Key Up Event. When you add a tilemap layer in the room editor, which we'll cover in a moment, it will be empty and you won't see anything, but it's actualy filled with these "blank" tiles, and when you start to paint tiles onto the tilemap layer, if you delete a tile, it's not actually being removed, but instead it's being changed for this "empty" tile too. Drag & drop is meh but you can use it anyway. GMS 2 isnt free, unfortunately, but its still an excellent tool thats relatively cheap for a high-quality game engine. 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. When you have multiple resources open you can also use 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. Now, create a new object (Ive named mine creating a prototype around that idea bottom center This is the Tiles and Views Section of our "My First Game" tutorial, and if you've done the first three Are complex RPGs possible, for instance? section Before you try it out, dont forget to drag your world object into the room with your box and player. In the previous 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. Sprites dont do anything, they are just pictures that are sometimes animated that we attach to things that have code, i.e. So, the player shoots an enemy and "kills" it and the game will award them a certain number of "points" which we'll add to their score. Next , select GameMaker Language instead of Drag and Drop . By default a view camera is static, ie: it won't move unless you code it to, but we can set it to follow an instance of an object automatically and without code using this button: Once you've set it to follow the player object, we also need to set the Horizontal Borderand Vertical Bordervalues. We have our enemy spawn object now, but we don't have anything to re-spawn the enemies when there are none left, so for that we are going to create a controller object called obj_spawner. 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. So, still in the obj_enemyStep Event, and before the action for playing the sound, we need to add the action Set Audio Pitch: When you use a sound effect or music in GameMaker Studio 2it is played with a pitch value of 1. section. section You can name this sprite now, something like "spr_background", and close the sprite editor before continuing (we don't need to set the origin of this sprite nor any of the collision properties as they are not relevant for tiles). This is a bit of forward thinking on our part, as we will eventually have the player "die" in our game, removing its instance from the room, and if we try to access the variables of an instance that. For more developer tutorials and news from Android Authority, sign up below! variable This can be very time consuming and error prone, so we use the instance variable instead to store the value. setting is pretty smart, and it does a good job, so I wont change it for my sprite. Let's quickly run through what you should have learned from this Note that because we already have the action Room Restartin the player object when they die, then when the player dies the title screen will be shown again, so the player can prepare before each game after dying. About us: Career Karma is a platform designed to help job seekers find, research, and connect with job training programs to advance their careers. 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. Make a new sprite, and fill it with red to make a 3232 red box. 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. Youll also see the small crosshairs move on the sprite. Where GameMaker differs, however, is in its relative simplicity and target audience. To create the player, right click no the Objects folder in the Assets Browser and create a new object. variable controls the objects horizontal position on the screen, and its measured in pixels. 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. , which will be where we put all of our code (more on this later). Just remember that for now, it will be appearing on a black background, section The same for the collisions mask, as having the wrong collision mask in your game will seriously affect the gameplay and the fun of the player. Create Sprite At the moment, our game just starts in the main game room, but we want it to show a title screen and have the player do something like press Enter or click anywhere to actually start the game. Right now everything is looking very empty, so lets get started making our game. Rooms Image Size The final action block should look like this: You can hit the Run button now and see what happens Before continuing, we should look at the concept of layersin a bit more depth. After a few moments, a window will pop up. Bounding Box Create something similar of your own and then drop it into the Sprites folder. This area is the actual room, which is currently a blank canvas on which you can place resources to create your game level. We want to change this so that the Assign Variable action will only be called if a key is pressed so now we need to drag it onto the right hand side of the if keyboard downaction like this: Now what we have is the "if" checking for a key and only if it returns true (the key is being held down) will it run the assign variable action. Instance variables are valid for any event in an instance and can be changed or read in other action blocks. We only need to set the key that is being checked now, so change the "vk_space" value for "vk_right" (the "vk_" variables are special built-in constantsthat are used to signify different keyboard keys). We are now going to use this variable in the Step Eventof the player object to control how often the shooting occurs, like this: What we have done is "nest" an if variableaction within the mouse down action, so it now reads "if the mouse is held down, and if the variable cooldown is less than 1 {do something}". section Another caveat of GameMaker Studio is that it is not free, whereas the more powerful Unity and Unreal Engine are. 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). The Key Up Event detects when a key has been releasedand won't trigger until that happens. we've covered two of the main ones, the layer system- and in particular tilemaplayers - and the camera viewssystem.

Thats about all you need before entering the prototype phaseno design document, no multi-step plans (yet). Its easy to read and type in, and it functions very similar to other languages. Create 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. This is easily done by simply changing the width and height of the room from the Room Properties, which by default can be found at the bottom left of the room editor window: You can see that the default width and height here are 1024x768, but that's too small so let's just double the widthvalue to 2048 by clicking on the input box and changing it. Its a flat purchase price, meaning that GMS 2 doesnt try to take your games profits or make you pay monthly. In this tutorial we will simply be adding a single sound effect when you destroy the enemy instances, so you can use any sound effect that you have on your hard-drive or you can use the one that we have supplied along with the tutorial, which will be found when you open the file explorer in the TutorialResourcesfolder, in the "Sound" sub-folder (if you have any issues, you can also find the sound here). This makes GameMaker ideal not only for beginners but also artists and designers that want to build games without learning to code. Click on the layer and drag it into the position between the Instancesand BulletsLayer. This then, is where we want our gravity to go! Name your project as you please and save it somewhere safe. You will learn a bit of code and a bit of game design as we go. event in our world object. The second part of the code checks to see if the Y position of the object is at the bottom of the screen. The next step in our GameMaker Studio 2 tutorial is where things start getting really fun. There are a lot of options here, but the first thing we need to do is switch the view "on". section For now, we will just leave it set at default with the room taking up the whole game window. GameMaker Studio 2 - Drag and Drop - YouTube There is a minor problem that we have to fix now, though GameMaker Studio 2will run rooms in consecutive order, meaning the room at the start of the room resource list is the one that will be shown initially when we start the game. Its up to you how you want to progress, and hopefully, this tutorial has equipped you with enough to get started and has given you the desire to learn more in the game industry. Before we end this tutorial, let's quickly add in a collision for the player colliding with the enemy. We now need to add a Step Eventto the enemy object. 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 need to add a Create Eventto our bullet. We have covered all the basics that you need to know to get yourself started making games, and we've given you a base game to work on and try to change or add to. 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. Return to our player object and add a new event; but this time, go to If you right click on the Fontresource and select Createit will create a new font resource and open the Font Editor: Following the naming convention
