How to implement muscle in box2d

Question

JavaScript

What type of joints is suitable for the implementation of connections that behave like a muscle.

Tried DistanceJoint but it doesn't react on SetLength

Answer 1

What do you mean by "muscle"? if you want to move the body to which the joint is attached, then you need to look towards the joint motor. example:

jointDef.maxMotorTorque = 10.0f;
jointDef.motorSpeed = 0.0f;
jointDef.enableMotor = true;

the movement will take place in the degrees of freedom of the joint
