There seems to be a bug.

I packed a .png-image with color RGBA(0, 0, 0, 50) and the result was RGBA(0, 0, 0, 10).

Is there something wrong with the alpha values?

raylib technologies14 days ago

Yes, it’s a known issue and has already been reviewed. An updated version will be published soon.

Do you plan on making this a library?

Kikasuru36 days ago

Also is there a way to remove all viewable sprites in the atlas? It'll be useful for fighting games that need a lot of sprites for animation.

Ray36 days ago

What do you mean? There is a clean button on the sprites list to remove all sprites from the atlas.

Kikasuru35 days ago

There can be sprites that have a red border around them that are not on the atlas, is there a way to automatically delete all the viewable sprites (ones without the red border)?

Ray35 days ago(+1)

Not for the moment but I take note about it, I can add it in a future but unfortunately not for next release.

Ray36 days ago

Actually most of the functionality of this tool is directly available in raylib. You can use raylib.

Do you have a src-code for this program?

Ray228 days ago

I'm afraid this software is closed source. Why do you need it?

Mabaraksha139 days ago

I will answer for them. Because by reusing the code of this editor, you can create a level editor that will be more convenient than the ugly Tiled.

Ray139 days ago

You can check the code of rFXGen, rGuiStyler, rGuiIcons and rIconPacker, they are open source and all my tools use the same base template so the code structure is almost the same. rTexPacker just has specific code to package sprites but that's a few lines of code because it uses stb_rect_pack library.

Ray304 days ago

Nope, unfortunately I never had a mac to learn how it works and create software for it...

ROYALKINGSJ304 days ago

ryanford1 year ago

Any plans to make this available as a Linux binary?

Ray1 year ago(+1)

I'm publishing a new version soon, I'll try to provide a Linux version by then.
