Finding how many physics objects are active

[Adversus]

Is there a way to do this?

There are more than one way.
the easier is to iterate over the body list calling function

Code: Select all

for (body = NewtonWorldGetFirstBody (world); body; body = NewtonWorldGetNextBody (world, body); {
int sleepState = NewtonBodyGetSleepState(body);
....
}

a more complex but more elegant and efficient way it to keep track when they become active by checking on the force and torque call back.
basically you can keep a counter and in the force callback you increment the counter if the body is active and decrement if is sleeping.

Thanks the easy way is fine.

It's for non-performance critical debugging.
