Drawing A Sprite On A Layer

[CryptidProductions]

I'm attempting to draw a sprite on a specific low-layer to use as a background but I can't figure out how to draw on a specific layer in such a way that I can move the sprite around each step for scrolling

Not gonna lie, getting kind of worried that I managed to finally find something so I want to that's so obtuse none of us can figure it out.

You want to create a sprite asset then store the element ID for it in a variable so you can move it. So, look at the functions:

layer_sprite_create

layer_sprite_x

layer_sprite_y

Alternatively, simply assign the sprite to an object, create the object on the layer, then move the object.

PS: It's worth noting that a single layer can actually hold mixed assets, so if you have a background layer in your room (for example) you can create an instance on it, or add a sprite asset to it etc... The idea that there are "instance" layers and "tile" layers is purely a fiction for the room editor to make editing things easier. A single layer can actually hold anything...

That's my mistake. I was trying to store an ID in from the layer_sprite_create and then do something like background_1.x so Game Maker was yelling at me about using a function as a variable. I didn't realize there was specific layer_sprite location functions.

Perfect. This setup gave me perfect scrolling with no jitter. I used room start since it's done a persistent game controller object.

Room start event (I'll add if statements to make it check the room to know which background to pull later on):

/// @description instalize background

background_1 = layer_get_id ("BG_1");
BG_1 = layer_sprite_create(background_1, 0, 0, Cemetary_Background);

End step event:

/// @description move background

//Move background
cam_x = camera_get_view_x(view_camera[0]);
cam_y = camera_get_view_y(view_camera[0]);

layer_sprite_x(BG_1, cam_x);
layer_sprite_y(BG_1, cam_y);
