I am working on a space flight simulator, at this point i'm trying to get an autopilot running to approach and stop at a defined distance to the target object.
I don't want the possibility to simply brake down the velocity to zero, in case the ship has to stop accelerating, turn arround 180 degrees by a defined turnrate and then start the engines to slow down until it reaches a velocity near zero were it can brake to zero an turn around again to face the target.
void Update () {
if(Input.GetKeyDown(_control.autoApproach) && !_approach){
if(_target.selectedTarget != null){
_target.approachingTarget = _target.selectedTarget;
_distance = Vector3.Distance(_target.approachingTarget.transform.position, _myTransform.position);
_way = _distance - _maxDistance;
_approach = true;
}
else
_approach = false;
}
if(Input.GetKeyDown(_control.stopAutopilot)){
_approach = false;
_MoObj.DefEngineOutput = 0;
}
if(_approach){ //if approach
if(!_braking)
RotateToTarget(); //turn to face target
Vector3 directionToTarget = _myTransform.position - _myTargetTransform.position;
float _angle = Vector3.Angle(_myTransform.forward, directionToTarget);
if (_angle > 179 && _angle < 181){
MoveToTarget(); //approach till < 2000
}
if(_rotateToBrake){
RotateToBrake(); //Turn around 180°
}
if(_braking){ //Increase Output to slow Ship down
_distance = Vector3.Distance(_target.approachingTarget.transform.position, _myTransform.position); //CheckDistance
}
//Decrease Output to decrease Speed before arriving at TargetVector
//Arrive at TargetVector by Brake();
//Rotate to View Target
}
}
private void RotateToTarget(){
if(_target.approachingTarget != null){
_myTargetTransform = _target.approachingTarget.transform;
_myTransform.rotation = Quaternion.Slerp(_myTransform.rotation, Quaternion.LookRotation(_myTargetTransform.position - _myTransform.position), _MoObj.TurnRate * Time.deltaTime);
}
else{
_target.approachingTarget = _target.selectedTarget;
RotateToTarget();
}
}
private void RotateToBrake(){
if(_target.approachingTarget != null){
_myTargetTransform = _target.approachingTarget.transform;
_myTransform.rotation = Quaternion.Slerp(_myTransform.rotation, Quaternion.Inverse(_myTransform.rotation), _MoObj.TurnRate * Time.deltaTime);
//_myTransform.Rotate(Vector3.down, _MoObj.TurnRate);
}
else{
Debug.Log("No Target for AutoPilot!");
}
}
My actual problem lies in the RotateToBrake() function.
I don't get it and its late now.
I checked nearly ever type of rotate function Unity comes up with, i tried a 100 times to print out myTransforms.rotation, viewports, rigidbody rotations i tried euler angles, Quaternions, defined angles, simple Transform.Rotate to AddForce Variants.
I tried to set a new Gameobject directly behind my ship to use turnto again but somehow i made it wrong.
Maybe some1 has an idea how to get the exact direction behind my ship and turn it there in a smooth way like a Quaternion.Slerp();
Or even a completly different Idea how to solve the hole thing...
