I found this patch somewhere in this forum and took it as a starting point to try to make a Tombola Sequencer (a ball bouncing inside a shape)

this video is covering the tombola sequencer on the OP-1 portable synthesizer. it is part of a series of OP-1 training videos.

OP-1 tombola sequencer

I am new with the phys and jitter objects... So I have many questions... If someone helps me solve one (even if it is only one) it will be of great help and contribution to this project.

2) How can I make the ball bounce and move only in X and Y (up, down and side to side) but NOT in Z (not back and front)?

3) How can I get bangs whenever the ball bounces or hits a wall?

4) How can I tell which wall it is in contact with? (so it can send a bang whenever it hits a wall, but send a different bang whenever it hits a different wall... we want a different bang for each wall)

5) How to prevent the ball from getting out of the container shape and falling when rotating the container shape quickly?

I will keep exploring and I'll share any progress I managed to make.

Zup!

what makes you think there are balls which automatically moves in all three dimensions?

any line from Xa, Ya to Xb, Yb describes a triangle in relation to the X and Y axis.

for "different walls" it is getting complicated at one point, because it might hit both in the corner.

when comparing the X and Y values of mr. ball and mr. wall you will know when the ball is "outside".

so when drawing graphics just use [clip] to reset e.g. -1 to 0 again, and the ball (or the mouse) will stop there.

usually in the same moment you are already calculating its movement in the other direction already anway.
