Hi, I'm new to Bullet and I'm trying to understand better how it works.
I got the following situation using discrete dynamic world:
1. Created a static rigid body to act as a ground.
2. Created a cylinder and a sphere rigid bodies with motion state.
When i apply a force (linear velocity) to the cylinder, it hits the sphere and the sphere goes to the exact location that i was expecting.
But, when i insert a second cylinder at the dynamic world, the things change a little. Even though i didn't hit this new cylinder, when I apply the same force to the first cylinder and it hits the sphere, the result is a little bit different from the first simulation. The sphere hits a position near the first one but not the exactly (actually, it's not really so close).
I'm trying to figure out why this happen but didn't get the point =/
The second cylinder doesn't have nothing with the motion, why does his existence change the world behavior? Is there a way to avoid this? What's happening on this scenary?
Thank you in advance!
