Impulse output

iTap Development

@Murtaza what is the "impulse" output from the collision behaviors for?

Hamed

It's basically how hard it got hit, or how hard it's getting hit over time.

In real physics words, it's the change of momentum over time.

@Hamed what units is the measurement?
When I was playing around with it, I'd sometimes get a number with a -354 or something on the end, why? I also got just plain words(it was like nan or nah or something) what do they mean?
Also, when the object was just sitting on the other object, there was still a number.

I noticed that the collision point for the while colliding behavior is always the point that it collided at, and won't change if the object rotates while they are colliding.

Also, a while back, I tried to make a newtons cradle, but it wouldn't work right. Will the physics engine work for it? Or does it just not support things like that?

Nan is probably "not a number" which basically means infinity.

Hamed

NaN means not a number like @Aidan-Oxley says.

I've built a newtons cradle, just make sure to set no air resistance so there is no energy lost and set bounciness to a number on each ball.

I believe the units of measurement is Newton seconds.

If you set air resistance to 0, that will make the Newton's cradle a perpetual motion machine, right @Hamed?

Hamed

Yes, it should never stop. That being said, the physics engine isn't perfect and there maybe a loss of energy somewhere through a rounding error.
