There is no air resistance or wind, and no forces affecting the body, except for my custom gravity, which is applied every game tick:
Code: Select all
const btVector3 gravity(0.0,-15.0,0.0);
rigidBody->applyCentralForce(gravity *tDelta); // tDelta = Time between last tick and current tick
Where could this discrepancy come from? Why is it slower than expected?
My physics knowledge isn't the best, so maybe I'm missing something? Are there any other forces involved that could affect the outcome?
