physics not working

self.thruster = NodePath(“thruster”) # make a thruster for the model
self.thruster.reparentTo(self.Mod1)
self.thruster.setPos(0,-2,10)

    self.thrusterFN=ForceNode('jump-thruster') # Attach a thruster force
    self.thrusterFNP=self.thruster.attachNewNode(self.thrusterFN)
    self.thrusterForce=LinearVectorForce(0,0,4000)
    self.thrusterForce.setMassDependent(1)
    self.thrusterFN.addForce(self.thrusterForce)
    
    self.actorNode.getPhysical(0).addLinearForce(self.thrusterForce)
    #self.thruster.setP(-45) # bend the thruster nozzle out at 45 degrees

I used this code from the manual to apply force to my model, but it doesn’t affect it. I want a force to push my model in a direction. Using a task doesn’t work either. Can someone help me get this to work, please?

I think there was some thing like enable physics some place in order to get the particles to work. Maybe enable physics is some thing like enable particles … you have to look for it.

Woaah!
I had actually given up on this question, since I thought nobody would answer.
Thanks treeform, I’ll look into it.

base.enableParticles me thinks.
