Manually draw a sequence in GameMaker
This is a simple script that is used for manually drawing sequences that are made of sprites. You can simply call draw_sequence(sequence_asset,frame,x,y,xscale,yscale,angle,color,alpha), as if it were a sprite itself.
It's mainly for my own use, but it might be useful to you.
My code basically goes through the struct from sequence_get(), and caches a list of what sprites to draw and where, so it is quicker to do every frame.
Features:
- draw a whole sequence at once with multiple translated, rotated, and scaled sprites.
- rotate, scale, and color a whole sequence
- image_index keyframes
Missing features:
- not tested with sequence tracks other than sprites.
- parameter tracks for "origin" and some others are not implemented. Only position, rotation, scale, image_index.
- image_speed keyframes are not implemented.
- there is no interpolation. My code is for using a sequence just like a frame based animation.
Otherwise, it should mimic the built in sequence drawing as close as possible.
draw_sequence_edited():
You can pass in a struct to change how specific sprites are drawn.
{
"sp_player_hat": {
drawfunc: function(sprite,index,x,y,xscale,yscale,angle,color,alpha),
(optional) visiblefunc: function() -> bool
}
}This is useful if for example you want to change the sprite of an item being held, or change the hat on someone's head.
