Very basic snippet, helpful for the paint in your script.

public static int getExperienceUntilLevel(int currentExperience, int level) {
	int experience = 0;
	for(int i = 1; i < level; i++) {
		experience += Math.floor(i + 300 * Math.pow(2, i / 7.0f));
	}
	return (int) Math.floor(experience / 4) - currentExperience;
}

pretty sure you copied this... at least give credits to whoever u copied from

Uh.. I interpreted it from this formula, which is from the Runescape wikia. 

I wouldn't really classify that as copying.. but I've references the source regardless..

As long as you understand and know which formula it is I guess it's fine..

What's the problem of understanding that formula?

Nice one matey, thanks for it .

Nice, but computing the required XP on each call (especially on paint) will only result in performance issues. I'd suggest just caching the values into a giant 2D array.

That's exactly what I do with my script ;)

Math operations are usually very expensive (Especially the Pow() operation)

I'd recommend just indexing a single-dimensional array

 

@Liverare, not sure why you would want to do a 2d array

 

EDIT: This is the one I use
