Well, I was looking for something to check if objects in a game collide.
I guess this is the closest I could find: (in the Rect class):
/**
* If the rectangle specified by left,top,right,bottom intersects this
* rectangle, return true and set this rectangle to that intersection,
* otherwise return false and do not change this rectangle. No check is
* performed to see if either rectangle is empty. Note: To just test for
* intersection, use {@link #intersects(Rect, Rect)}.
*
* @param left The left side of the rectangle being intersected with
this
* rectangle
* @param top The top of the rectangle being intersected with this
rectangle
* @param right The right side of the rectangle being intersected with
this
* rectangle.
* @param bottom The bottom of the rectangle being intersected with this
* rectangle.
* @return true if the specified rectangle and this rectangle intersect
* (and this rectangle is then set to that intersection)
else
* return false and do not change this rectangle.
*/
* public boolean intersect(int left, int top, int right, int bottom) {*
* if (this.left < right && left < this.right && this.top < bottom &&
top < this.bottom) {*
* if (this.left < left) this.left = left;*
* if (this.top < top) this.top = top;*
* if (this.right > right) this.right = right;*
* if (this.bottom > bottom) this.bottom = bottom;*
* return true;*
* }*
* return false;*
* }*
Thanks.
