On or off ground

Troubleshooting General Help

Can anyone inform me of another way to check if your on the ground or not the way i'm using seems to be inaccurate



SyntheticButton collButton = feetNode.getCollisionEventHandler();
           contactDetect.addAction( new InputAction() {              
               public void performAction( InputActionEvent evt ) {
                   ContactInfo contactInfo = (ContactInfo) evt.getTriggerData();
                   Vector3f vec = contactInfo.getContactNormal(null);
                   if (vec.dot(Vector3f.UNIT_Y) > 1f){
                       offGround = true;
                   }
                   Vector3f vel = contactInfo.getContactVelocity(null);
                   if (vel.length() > 10){
                       System.out.println("POWERFUL CONTACT: "+vel.length());
                   }
               }              
           }, collButton, false );

hmm the current way seems even more inaccurate than i thought i can be 10 meters off the floor and it doesn't register…

maybe you can shoot a ray from your character down and check the distance that way

hmm i've never really had any use for it until now t shouldn't affect performance at all correct and i set it up and went through the class but how can i detect if it hits a surface? I would have to set up my test plane differently?


I've done HelloMousePick  :P
