What is the best way to rotate a ship slowly towards a target with torque using physics?
I have a floating boat that I am trying to control with pure physics, however thus far it hasn't been working that well, beyond the buoyancy which works perfectly.
At the moment, I've got a vague target look-at that rotates, however it tends to over-shoot and then won't stop when it gets to the target, resulting in a weird orbit. What I want to do is keep it from over-shooting when it's lined up with the target, and then move to the destination and finally stop, until the destination changes.
This is the code producing the not-quite-working effect:
TargetLocation = TempTarget.position;
Vector3 Heading = TargetLocation - transform.position;
float direction = Vector3.Dot(Heading, -transform.forward);
float Distance = Vector3.Distance(TargetLocation, transform.position);
Debug.Log("Direction Status: " + Mathf.Sign(direction));
if (Distance > 1.5f)
{
// Is the Target in front or behind me? //
// In Front //
if (Mathf.Sign(direction) == 1)
{
currentThrustPower = 600;
} else
{
currentThrustPower = 0;
}
if (direction < 0.55f)
{
torquePower = 1400;
}
else
{
torquePower = 0;
}
} else {
currentThrustPower = 0;
torquePower = 0;
}
RTorque = new Vector3(0, 0, torquePower);
Vector3 forceToAdd = -transform.up * currentThrustPower;
boatRB.AddRelativeTorque(RTorque);
boatRB.AddForceAtPosition(forceToAdd, waterJetTransform.position);
Calculate the angle between velocity of boat and target direction of boat(target.transform.position - boat.transform.position)
var angle = Vector3.Angle(rigidbody.velocity , target.transform.position - boat.transform.position);
When boat orbits around target this angle must be around 90.
So when this angle gets nearer to 90 decrease the speed of boat.
