How would you make a ball bounce similarly to how it shown in this picture?



Using the “turn 180 cw block” is rather bland as is literally bounces right back where it came from.

How could I calculate the bounce physics for this?

It depends whether you hit a horizontal or vertical wall.

If the ball hits a vertical wall (left or right wall) as in your picture then
Rebound Direction = Approach Direction * -1

If the ball hits a horizontal wall (top or bottom wall) then
Rebound Direction = 180 - Approach Direction

Try 180-direction

turning 180 degrees would not work as it would bounce back the way it came and that is not how reflection works

I think you subtract 45 from the angle it came from

when green flag clicked
forever
if <touching [wall v] ?> then
point in direction ((0) - (direction))
end
end

This script works in bounce off edge.
