i've been trying to get getResource to work correctly this whole morning but so far the only way i've had to get it working is by moving the res folder to the bin folder and then using getResource like so
URL url = MyClass.class.getResource("/res/gfx/entity/entity1.png");
But is there not any way i can make it so res is outside the bin folder?
Nevermind, i can't believe how stupid of a fix that was.
I added the res folder to the main project folder rather than bin, then went in eclipse
run > run configurations > classpath > select user entries > advanced > add folders > select res
then when calling a folder from res, rather than doing "/res/gfx/entity/entity1.png", i did "/gfx/entity/entity1.png"
Problem solved!
