Re: A Shader Que.

Just add this at the beginning of your code: do local mt = debug.getregistry().Shader local old_send = mt.send mt.send = function (shader, variable, ...) pcall(old_send, shader, variable, ...) end end This should be the default behaviour, but the LÖVE developers don't seem to agree.

A hot potato

Hi, everyone. This is the new guy. :)

I have a question.
I tried to move a Sprite using a keyboard button and then draw it using the draw function.
Finally, my Sprite won't move. I have to keep clicking on the keyboard button to move it. :|
Why? :shock:
