3  Game Development / Newbie & Debugging Questions / On-screen joystick with libgdx, boundary stops? on: 2013-10-11 21:42:51
Hi all, I am new to java and libgdx and maths come to think of it!  I am trying to make an on-screen joystick for the android side of life.  So far I have drawn a filled circle and another smaller filled circle at the same centre coordinates.  I have the thumb circle moving around in regards to mouse and touch, with 'touchDragged' and resetting the thumb to centre with 'touchUp'.

At this point I am stuck!  I can use .dst to find the distance between the centre points(vector2) and the thumb circle(vector2) and I can find the angle 0 - 360 from the x line.  But how can I set the bounds and no the x and y coords so you can't move the thumb circle outside the bounds of the larger background circle.

I think the solution involves soh cah toa but my limited math skills are letting me down.  Can anyone point me in the right direction please I have been trawling the internet with limited success.

Many thanx in advance
