Use Transform, Rigidbody, Rigidbody2D or nothing at all (if updatePosition = false).

Unity forward vector 2d update#

currentPosition = tr.position // MUST NOT UPDATE FROM TRANSFORM! WILL BREAK DETERMINISM! TODO: Add this into the clampedPosition calculation below to make RVO better respond to physics.

Grab the position after the movement to be able to take physics into account. The Transform may not be at #position if it was outside the navmesh and had to be moved to the closest valid position.Ĭontroller.Move((nextPosition - currentPosition) + accumulatedMovementDelta) If (controller != null & controller.enabled & updatePosition) Vector3 currentPosition = simulatedPosition Use a local variable, it is significantly faster.

This all exists as part of a complex solution. I extracted this into the function CalculateVector2Forward, which is invoked inside TraverseFunnel and FinalMovement. There are two functions which use Quaternion * Vector calculations which need replaced.

John Pan's Lockstep Framework (deterministic).

Aron Granberg's A* Pathfinding Project (non-deterministic).

I suppose there's no reason to calculate it in 3D, as that's just added complexity, elevation gets tagged on later. This is fine, because the pathfinding and avoidance library converts Vector3 to Vector2, to calculate avoidance on a 2D plane. public static Vector2d CreateRotation(long angle)

I do not have a deterministic quaternion class, and the deterministic code I have found elsewhere uses a deterministic Vector2 to store rotation data instead of a Quaternion. The problem is that there are some operations which use quaternion times vector calculations. I'm just in the process of replacing the data types with deterministic vector classes. There are custom vector classes I have picked up elsewhere which use longs instead of floats to store position data deterministicly. It has to be deterministic, so I'm editing a pathfinding library which uses floating point based classes (this is with Unity) like Vector2, Vector3, Quaternion. I am working on local avoidance and pathfinding code for a 3D strategy game. Edit: Having to edit this question extensively because DMGregory was right and there were unexpected consequences.
