Checking whether a position2d<s32> is within an IGUIIm

I saw some function within Irrlicht yesterday that checked if a given position2d was within either a rect or a IGUIImage... today I can't for the life of me find it... does anyone know where it is? i could make it myself, but i'd rather not clutter up my code with either a long if statement or an unneeded utility function.

Thanks in advance.

well im not sure if ive seen that code but the logic isnt that hard, if the position.X is greater than the rect.Left but less than the Rect.Right, and the position.Y is greater than the rect.Top but less than the Rect.Bottom... then return true.. else.. return false... simple kinda function.

If you want to find which GUI element your mouse is over, use getElementFromPoint(), http://irrlicht.sourceforge.net/docu/cl ... nt.html#a6

It'll work for anything derrived from IGUIElement.

Code: Select all

  rect.isPointInside(point); // will return true if point is in rect

@ImNoHelp: Thanks, I did that earlier, it just looked really ugly and I didn't want to resort to it unless I had to.

@Conquistador, vitek: Thanks, either should do the job nicely!

Everyone, thanks again for all your help!
