Also, maybe you could achieve the necessary overlap/collision event that I could not find out of the box with this extension by @richard, perhaps either begin overlap with or is within region?:
@makecode or anyone: Are there any other ways to detect collision with or being within the screen boundries of 120x80 for text sprites, other than my proposed check of changing vx OR vy when hitting the screen boundries and bouncing in new directions, without using extensions and tilemaps?
