Bomb tilts as it falls

by rennie moffat · in Torque Game Builder · 09/22/2009 (4:49 pm) · 4 replies

Edit, This code is designed to make a bomb fall from a plane. It sets the downward velocity and rotation of the bomb so it's nose rotates toward the ground upon release. My problem is that I also want it, the bomb to have an initial xVelocity @ creation/release. However, my setImpulseForce does not do the trick, any insight into what I may be doing wrong?

Bonus Question:
And a million points for anyone who can tell me how to link a %this.bombImpulseVelocityX to %this.planeVelocityX at any given moment.


Thanks

   %template.addBehaviorField(initialVelocity, "Ximpulse given to bomb @ creation", float, 100);
}


function BombRotateBehavior::onAddToScene(%this, %modifier, %worldPos)
{
   %this.startRotation = %this.owner.rotation;
   %this.owner.setAngularVelocity(%this.rotateSpeed);
   %this.owner.setImpulseForce(%this.initialVelocity);
}

    You are only setting a single value and not a vector there.
    %this.owner.setImpulseForce(%this.initialVelocity, 0);

    Sorry, I just plugged it in and it still does not work. I would have thought that by setting it as a behavior field (initialVelocity, float, 100), as I did would work.


    Even still tho, I did use your method, and nothing, any suggestions?

    Hi,
    I have gone over this code, and tested. In testing I have noticed one thing. Neither my initialVelocity nor my rotationAmount behavior fields are working. No matter what they are set to the action remains the same. I would really like these two factors to play a role. If anyone has any insight, please let me know.



    Thanks
