If on Edge, Bounce (block)
|If on Edge, Bounce|
The If on Edge, Bounce block is a Motion Block and a Stack Block. The block checks to see if its sprite is touching the edge of the screen with the move steps block — and if it is, the sprite will point in a direction that mirrors the direction from which it was coming. It uses a line perpendicular to the edge to determine the reflection angle.
- Preventing a sprite from partially leaving the screen (often, this is followed by the Point in Direction block to stop reflection)
- Games such as "Pong"
- Allowing sprites to bounce off the screen:
when gf clicked forever if on edge, bounce move (5) steps
- It also works for games such as fish.
when gf clicked forever turn cw (pick random (-10) to (10)) degrees move (3) steps if on edge, bounce wait (0.01) secs
Some users in the suggestions forum have requested for a block to be implemented simply called "bounce", which would allow for sprites to bounce when they collided with other sprites or with colors.
