Re: how to stretch image out from center like w/ skins / theming?

Hi girng (I think) what you're referring to is 9-slicing . It's possible in any language. Using that term I'm sure you can find tutorials on how to do it. Off the top of my head, in Love2d I'd just use a mesh taking care of the coords and uv coords - you could do it "manually" with a bunch of quads...

I don't think this will have any meaningful impact on performance. As for memory usage, Lua's garbage collector will take care of it, so it's fine.
thanks for support and information. i feel better =]

is initializing a local variable in mouse move ok?

for example, look at all the new memory addresses it creates. is this normal, bad, ok? https://i.gyazo.com/1d0a1dbd698980d2957f90dbdcbda976.png i use it because of my is_overlap function code: https://i.gyazo.com/4966889693317e1de18359030abd37c1.png i'm also trying to get `camera:mousePosition()` to...

Re: how to attach a shader to a sprite?

That shader only draws the outline itself, not the sprite. After drawing it, you need to draw the sprite again. When you say "glow", I'm not sure if you mean a bloom effect, or an outline. These are different effects. If you mean bloom effect, this thread talks about it, https://love2d.org/forums/v...

Re: how to attach a shader to a sprite?

You set the shader you want to use, then draw the sprite you want to use the shader on. http://blogs.love2d.org/content/let-it-glow-dynamically-adding-outlines-characters can be relevant, although it's probably for an older version; still some of the techniques may still apply. ty. just read over i...
