method
Rect.contains
Rect.contains(r, px, py) -> bool
Tests whether the point (px, py) falls inside the rectangle. The left and top edges are inclusive; the right and bottom edges are exclusive, so adjacent rectangles tile without overlap. The classic use is a mouse-in-button hit test.
Example
program Demo {
handler Step phase Update {
if Rect.contains(button, mx, my) { press() }
}
}
