2 issues about HingeJointMotor
Posted: Thu Nov 22, 2018 5:33 pm
(1) The first time the HingeJointMotorTarget() is reached it works as expected, but sucesive times it doesn't; it changes values as you can test with snippet. Is there a formal explanation of it, or is it a bug?
(2) Is it possible to perform hingemotor actions with mass=0.0 for the entitybodies?
