cpBodySetVelLimit with negative value

[ddt]

Hello,

I am simulating an object going up and down. I want to limit the upward velocity to a certain negative value, for instance:
cpBodySetVelLimit(_ballBody, -60.0);

But as far as I can see the speed is limited also for downward direction because when the object goes down it reaches a limit velocity of:
+60.0

Furthermore, once the object reaches the limit velocity (either -60 when going upwards or +60 when going downwards) it begins to bounce between -60 and +60.

QUESTION:
How can I limit the velocity of the object but only in a particular direction?

Thanks in advance.

You need to write your own integration callback. See the planet demo for an example.

Great!.

Thanks for the prompt reply.
