Hi there,
Every tick I am trying to read the current Force that holds a joint together with GetConstraintForce.
The constraint is initialized but the GetConstraintForce always returns (0.0,0.0,0.0).
I explain:
Two rigid bodies are connected with a linear constraint with a linear motor enabled.
I try to keep these two bodies at a certain distanced and so I set the target position of the linear motor every tick with “SetLinearPositionTarget”. The Linear Motor moves to that position. Good.
But if I apply a slight external force to one of the rigid bodies, the distance between the the two rigid bodies will change a bit but the Linear Motor does not fully correct that.
I want to find out why that is so I would love to see which Forces the Linear Motor generates in order to correct the position.
If I access the constraint with: constraint->GetConstraintForce(Linear, Angular),
the values I get back are all zero.
Why is that?
Hope you can help me
