This is not permitted in The Room Editor, but when creating things dynamically you can do this, which is why functions like layer_get_all_elements exist. Or you could have a background element with a tile map element to create the look of a room. So, for example, you may have a layer for enemies, and on that layer have the enemy instances as well as certain sprite assets that are only related to that enemy. IMPORTANT When creating room layers you can have multiple different element types on one layer. Particle System Elements: part_system_create_layer Right-click on Rooms on the resource tree and select Create Room.NOTE If you change any room asset in this way, the change is permanent and will be maintained for the entire duration of the game, even if you call the room_restart function (closing and restarting the game will reset the room properties though). NOTE These functions should never be run from within the room that you wish to change, but rather be run from an instance in another room first. You can also use the following functions to find out if a room exists, get its name (as defined in The Asset Browser) and general info: This only applies to code written at the root of a script, but not to functions created inside scripts, as those functions can be executed at any time during the game. drawsprite(spricon, 0, x, y) In this function, you tell GameMaker four things: The sprite you want to draw. Second, expand out the Collision Mask options, set the Mode to Automatic and the Type to Precise Per Frame (Slow). First, make sure the origin is still in the top left. If you’re using GML Code, use drawsprite (), and in GML Visual, use Draw Sprite to draw a sprite to the screen. Close the sprite editor and go back to the sprite itself. Lets talk about realtime lighting effects in GameMaker and how to create them with ease. Once you’re in the event, you can draw a sprite with a function.

Everything else will be inherited from the parent room, but now the tiles will draw using the tile set chosen. Lighting engines can be complex if youve never built one before. NOTE The variables listed above will not be valid in a script, as scripts are executed before the first room is loaded. This would normally require you to duplicate the room and redo the tile set by hand, but with inheritance, you simply set the new room as a child and change the tile set that is used to draw the tilemap layer. The following global variables and functions can be used for getting basic information about any given room: This section has all the general GML functions and variables related to rooms, for getting information about them as well as for setting certain properties within them. By default, a new GameMaker project has a single room added to it. You create them in the IDE using The Room Editor or at runtime using the functions under Modifying Rooms.Īny GameMaker game must have at least one room in it for it to run, but you may need many more depending on the type of game and how you structure your project. Create games for Windows, Mac, Linux, Android, iOS, HTML5, Xbox Series XS, PlayStation 5, and Nintendo Switch. Rooms are where everything happens in your game. GameMaker is a complete development tool for making 2D games, used by indie developers, professional studios, and educators worldwide.
