DISCLAIMER: I’m utilizing Unity 5.6.5f1 for this code, I truthfully do not know if there could be API updates on later variations, although I do not assume so.
I attempted to make a easy Third Person Camera that displaces and rotates in direction of a given goal, with the next key parameters:
- Following sorts for each displacement and rotation. Right now the enum is simply { Instant, Smooth }.
- Axes to disregard for each displacement and rotation, all axes in an enum.
- Axes to invert for the orbiting performance.
- ‘Relative Following’ for each displacement and rotation. If the flags are checked the displacement/rotation will probably be relative to the goal’s orientation (‘goal.rotation * displacement’ and ‘goal.rotation * rotation’ for displacement and rotation respectively).
- An offset vector, which is affected by the displacement relative following’s flag. It is handled as a normalized vector at runtime.
- A scalar of the aforementioned offset. Which is mainly de distance between the digicam and the goal.
- An offset vector as Euler for the rotation, it’s equally affected by the rotation relative following’s flag.
- Other attributes, reminiscent of ‘displacementFollowDuration’, ‘maxDisplacementFollowSpeed’, ‘rotationFollowDuration’, ‘maxRotationFollowingSpeed’, and many others., are for the sleek following. The attributes not talked about are both self-explanatory or irrelevant (at the least that is what I need to assume, right me if I could also be fallacious).
The Problem:
When the sleek flags are enabled for each displacement and rotation, the digicam begins to shake, I believe it has one thing to do with the rotation.
Things I’ve tried already:
- Call the rotation and displacement following on totally different threads (being Update, Late Update and FixedUpdate), not but on coroutines. This time I made an enum ‘LoopType’ to encapsulate all threads, and keep away from re-compiling every time I transfer the capabilities.
- Use totally different sorts of time deltas. By the identical vogue of the threads, I made an enum ‘TimeDelta’ which encapsulates the three forms of time deltas Unity affords.
- Change the sleek capabilities for each displacement and rotation, reminiscent of Lerp, SmoothDamp, Slerp, even customized elastic capabilities, and many others.
- Sacrifing 1 body by following the goal’s level of the final body, as proposed right here.
- Given that the goal’s displacement is that of a Rigidbody, this publish suggests to connect a Rigidbody to the digicam and displace/rotate it by Rigidbody.place/Rigidbody.rotation respectively.

What I Want to Know:
If I’m lacking one thing, I’m utilizing the fallacious capabilities, calling the capabilities within the fallacious threads/orders, and many others.
Please let me know if there may be extra info I’ve to supply.
