Collision detection

p = point(10, 20)

if inside(p, rect(20, 50, 30, 60) then

end if

if p.inside(rect(20, 50, 30, 60) then

...

end if

if sprite(n).intersects(sprite(m)) then

end if

if sprite(n).within(sprite(m)) then

Rectangles are specified as (left, top, right, bottom).

If the sprites are drawn in matte ink, the intersects and within

methods use the outline of the sprites rather than the bounding boxes.

Keyboard interaction

on keyUp me

if the key = ”a” then

...

end if

if the keycode = 123 then

put ”Cursor left”

end if

end

if keyPressed(

”a”) then

Catch the keyDown event to detect when keys are pressed (rather than released).

Key codes for the cursor keys are 123 (left), 124 (right), 125 (down), 126 (up).

Shift, Alt, etc. doesn’t generate events, but you can query their status inside

an event handler through the shiftDown, the commandDown,

the controlDown, and the optionDown.
