I need to draw an arrow morph from center of one given morph to center of another given morph.
Any help would be appreciated.
Assuming a
and b
are your morphs:
arrow := (LineMorph from: a center to: b center color: Color red width: 2) makeForwardArrow.
arrow openInWorld.
If you want to update the position after the morphs move, do this:
arrow setVertices: {a center. b center}
