thanks for taking the time to help me. It ALMOST works now, the stick acts lke imgCenterY and imgCenterX is a bit further down then they really are. I know I'm using the right positions cus if I draw a circle at that position it gets drawn in the exact middle of my joystickBG.
this is how I add the stick: canvas.drawBitmap(joystick. get_joystick(), touchingPoint.x - 13, touchingPoint.y - 13,null); this is how I add the joystickBG: canvas.drawBitmap(joystick.get_joystickBg(), initx - 50, inity - 50, null); and this is the changed code: int imgCenterX = initx + joystick.get_joystickBg().getWidth()/2 - 50; int imgCenterY = inity + joystick.get_joystickBg().getHeight()/2 - 50; Point imgCenter = new Point(imgCenterX, imgCenterY); int dx = touchingPoint.x - imgCenter.x; int dy = touchingPoint.y - imgCenter.y; float distance = FloatMath.sqrt(dx * dx + dy * dy); Log.d(TAG, "destance HERE: " + imgCenterX + " : " + touchingPoint.x); // Out of bounds check. final float radius = 25.0f; if (distance > radius) { touchingPoint.x = imgCenter.x + (int)(dx * radius / distance); touchingPoint.y = imgCenter.y + (int)(dy * radius / distance); } -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
