attach two images together inside memory, ImageData:paste() ? no glitch when moving together

[gcmartijn]

At the moment I have an optimised atlas file with a separated human parts, head (static) head (talking frames) body walking.
I'm not going to use legs and arms, they are attached to the body in the atlas file.

Inside the game I was placing the head on top of the body, and move it with the body.
I math.floor(everything + 0.5) but sometimes I see a small glitch.

For me the only solid safe solution in my opinion at the moment is, not adding body parts like this, and make a bigger atlas (with all options).
But then I need to do two things (that I don't want).
1. change photoshop files
2. create bigger atlas files (not really a problem)

So then I thought, why not create the full body + head inside the game?
It cost a little more memory, but then I can remove code that I was using to attach the body parts, and there is never a glitch.

Is ImageData:paste() the way to go, to merge two quads inside the memory?
Or are there other ways that are better, to do this?

Code: Select all

-- i use quad to read the atlas and frames
local quad_body = newQuad()
local quad_head = newQuad()

-- is ImageData:paste the thing that I have to use to merge to images together?
-- and if that is the case, and have the final quad_merged, then I can destroy the atlas.resource
quad_merged = ImageData:paste()

-- in the draw
love.graphics.draw(atlas.resource, quad_merged, x, y)

Thanks for the info.

Just draw to canvas, you can also save it to file.

I'm glad that I ask it first Canvas sounds better, so each 'human' is then a drawable Canvas.
Going to work/test that.

If you using something like this (spritesheet layers of body tiles and clothes)

you can also use the array of sprites:
