gamemaker studio 2 tutorial drag and drop

Bounding Box Now drag an instance of the controller object obj_spawnerinto the room and run the game. To answer that we need to back to the Sprite Editorand explain another of its features - the ability to set up a collision mask. You can delete it, and you can edit it, and you can create further rooms using the right button We can now associate the sprite to the object by selecting it from the list of available sprites. But what isa layer? You'll see that we have the option to Stretchthe background image too. Each time the game refreshes, this event is triggered. 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. section We actually need to use a functionto get the angle that we want to set the sprite to, and then we'll store the value it returns in a variable ready to set the rotation of the instance. Next We currently have two instance layers (one for the player and the enemies, one for the bullets) and a background layer. This controls the vertical position of our object, with the top being zero. First you would open GameMaker Studio 2, and then click on the New Projectbutton shown on the main Start Page: You will then be presented with two options: Drag and Dropis the powerful visual scripting language that permits you to code a project using chained action blocks, while the GameMaker Language (GML) is the propriety scripting language that permits you to create games using the code editor. We have no need to change any of the properties for this sprite so you can close it now and then create another one and call it "spr_titlescreen". Drag and Drop free game engines to run the game. Note that if we hadn't flagged the "relative" check-box, then we would be settingx to 4 rather than adding to it, and if we'd used -4 instead of 4, then we would have been subtracting4 from x. section sections then you've already got the beginnings of a small arena shooter game. 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. In case youre stuck you can get a zip of the entire completed project from our GameMaker Studio 2 tutorial here: variable To actually scale it up we need to use the Step Event, so add that now. F5 If you have used your own sprite then click the image where you think would be best place to put the origin for the image. (for the sprite). Youll now be able to drag and resize the box as needed. 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. To do this, you will need to click the button that is currently labelled "No sprite" and select the sprite "spr_player" from the list of available resources: Associating an object with a sprite in this way means that when you place an instance of the object in the game room, this is what will be drawn and certain attributes of the sprite will be used by the instance. 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. Resource Panel After a few moments, a window will pop up. By default this is set to 0 for every instance in the room, but it can be changed at any time using the Set Instance Rotationaction . Normally you'd have a mix of both things, with some rooms fulfilling multiple purposes (like one room for all your different menus) and other rooms for a single purpose, like an overworld room, or a level room. Now we have to make the time variable do something. Just in case, in the We are now going to add a Draw Eventto our object. You'll see that the image now appears in the top left corner of our room as a background, but that's not exactly what we want we want it to tile across the screen. At the moment it's 32px, which means that the player would have to move right up to the edge of the view camera window before it will move to follow, which in an arena shooter like ours is just too small we want it to move before that so that the player can see what is around them. The workspace is the name we give to the main area in the middle of the window where you will be doing the bulk of your work. Yes you can. Lets change that. With them all selected simply press the key to delete them. 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? near the size button. are blocks of code attached to objects that run when that event happens. There are a lot of options here, but the first thing we need to do is switch the view "on". and then section of the We can do this with a second So double click on the object "obj_player" from the resource tree to open it in the current workspace if it's not open already. You should now have a player ship that can move and shoot, and bullets that are timed to come out at regular intervals. We need to create a new object for the spawner so do that now (click on the Object resource folder and select Create), and name this object obj_enemyspawn. It's also not a very big play area for the player to move around in, making the game feel cramped. 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. obj_player This layer will be used to show the background tile sprite that we added previously. Again, we want to check that the player is on the ground before any of this happens, though: Now hit play and you should find that you can actually control the player, explore the level, and fall into pits. 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. Learn about the CK publication. It can become tricky to remember whats what, so this helps with organization. In this tutorial, we will walk through the start of that process together in a game This is necessary because the tiles themselves are in the Tile layer and dont have any impact on our game objects. 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. By default, its set to Basically, you can set a view camera to be any size, and then set the view port to be a different size and the camera view will be scaled to fit in that space. , youll see we have a default starting room for our game. The title text sprite says "Press Enter To Start", so we now need to have our instance detect that key and go to the next room to start the game. The Change Object Instanceaction. Sprite However our tile set has all the tiles packed right beside each other, so we don't need to worry about this. is a bit different to previous ones in that we won't be using anyDrag and Drop actions. So, double click on the Player in the Asset Browser and then choose Events > Add Event. We had added in enemy spawn objects but we don't need them anymore so select them and delete them (/ + to select, and to delete). If you open the room editor for our game room (double click on the resource in the Resource Tree), you will see that by default the Layer Editoris shown docked to the top left of the Room Editor workspace: Currently we have two layers: "Instances" and "Background". This area is the actual room, which is currently a blank canvas on which you can place resources to create your game level. tutorial_game_files.zip However they are also unique to each instance, so if you have 100 instances of "obj_player" in your game, they will all have an instance variable "cooldown" since you defined it in the base object, but each one could have it set to a different value throughout the time the game runs. You can close the font editor now, as the next bit of styling we need to do is done through code. For now, we can just use a static character that glides around the screen. The smart thing is that there is an Auto Tiling option that will automatically make that judgement call for you. So, objects are in the resource tree, and are then used to create the instances that populate our game room. We want to get one final value now so that we can position the text correctly in the middle of the screen, so add a final Declare Tempaction: Now we have those values in our temporary variables, actually drawing the text requires a single action - the Draw Valueaction : All we are doing here is taking the position of the view within the room and then using those values to position the text we want to draw at a relative position, meaning that it will now move with the view camera (specifically, it'll always be at the top of the view port and centered). This object will be for our player and is what will permit it to move and shoot in the game room. New We are going to go ahead and create an object now. First you would open GameMaker Studio 2 , and then click on the New Project button shown on the main Start Page:. Rooms This is a simple way to animate your character while moving. , which is a special variable that all objects have, and making it equal itself minus 5. 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. Double-clicking it will open the room tab for that room, which is just a black background for now. I'm no programmer at all, so I would need to use the drag & drop mode. 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. 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. Let's go ahead and create our first sprite resource. You might have to squint a bit though, as it's written rather small and isn't very easy to read, so lets fix that now. and set the width and height to 6464 pixels under . With this action, we check to see if there is an instance of the player object in the game room because later we want to access certain variables from that instance. This code makes sure time stays between 0.1 and 1. Osomething This is done by checking the box labelled View Visible. At the time of writing the engine is in version 2.3.1.542. Another caveat of GameMaker Studio is that it is not free, whereas the more powerful Unity and Unreal Engine are. GameMaker Studio 2 is a 2D game engine; so if you have dreams of building the next Doom, then youll need to look elsewhere. After completing this As mentioned briefly in a previous tutorial, all games run at a speed which is defined by the number of times the game loop runs in a second. Why? We need an idea before we start prototyping, so lets come up with one now: Id like to make a top-down adventure game where you can slow down time to solve puzzles.
