Need help with rotation
Hi, Im writing a simple tank game, It has a tank with a turret and a cannon attached and a hilly terrain.
The problem is that when the tank is at an angle the script doesnt rotate the turret and the cannon correctly. The turret house should only rotate on Z and the cannon attached on X. I think the problem is that my script doesnt take into account the new angle the tanks is in.
Can anybody help with this problem? Thanks.
The following script controls the turret.
var TargetLoc : Vector3; var targetObject : GameObject; var RotateSpeed = 6.0; function Update () { if(targetObject !=null ) TargetLoc= targetObject.transform.position;
// Rotate towards target
var TankRotation = transform.rotation;
var targetRotation = Quaternion.LookRotation (TargetLoc - transform.position);
transform.rotation = Quaternion.Slerp(TankRotation, targetRotation, Time.deltaTime * RotateSpeed);
transform.localRotation.y = 0;
transform.localRotation.x = 0;
var targetRotation2 = Quaternion.LookRotation (TargetLoc - transform.Find("TurretHouse/Cannon").position);
transform.Find("TurretHouse/Cannon").rotation = Quaternion.Slerp(transform.Find("TurretHouse/Cannon").rotation, targetRotation2, Time.deltaTime * RotateSpeed);
transform.Find("TurretHouse/Cannon").localRotation.z =0;
transform.Find("TurretHouse/Cannon").localRotation.y =0;
}
I think Ive realized the problem. It has to do with the change in x axis when importing from blender. http://answers.unity3d.com/questions/6635/asset-import-from-3dsmax-rotation-issue
Have a look at this question, which goes into detail on locking rotation and that kind of thing. It also has a good follow script, just make sure your player is tagged "Player".
You could also separate the turret as a game object and the tank as another game object and reprogram 2 scripts one for tank and one for turret. And possibly use input functions to control the tank and turret as u see fit.
The Tank and the turret has its own script. The tank is controled my the keypad, and the turret locks on to a target via mouse. $$anonymous$$aybe I didnt explain my problem correctly. The turret and cannon rotate, on a level surface, correctly. It aims the cannon at its target. But when the tank goes up a hill or is leaning sideways, the aim is of. The turret doesnt rotate correctly. It appears to not rotate enough...

just another suggestion, I would make sure that the script is operating in local space not world space. When in local space, the script should ignore the world space rotation of your tank.
