They possible with Slick? I've been trying to fix mine for over an hour now..
Downloaded new lwjgl, can't find a new Slick though.
Just can't seem to get Image graphics from the players image (or any other image), which means I can't alter my images for shading..
Is there any way around this? Cause every time I try get the image's graphics with image.getGraphics(); it throws a null, I've also had this error;

I've tried making the images on the initialization too.

Opinions?

Use libgdx Smiley Sorry, I don't know enough about slick to help, but consider the switch.

You can only do image loading and rendering on the GL thread, i.e. through your game's init() method.

I'd also suggest LibGDX as it will be more suitable for per-pixel lighting and shaders.
