Convert from unity 2021 to 2022

[lacasrac]

unity 2021:

public void SetSimplices(int[] simplices, SimplexCounts counts)
{
    this.simplices.CopyFrom(simplices);

how to convert this line to 2022?


Assets\Obi\Scripts\Common\Backends\Burst\Solver\BurstSolverImpl.cs(314,37): error CS1503: Argument 1: cannot convert from 'int[]' to 'in Unity.Collections.NativeArray<int>'

Hi!

You can use CopyFromNBC from the Unity.Collections.NotBurstCompatible namespace, since CopyFrom has been removed in the latest Collections package version:
https://docs.unity3d.com/Packages/com.un...sions.html

one more thing:


private void UpdateKinematicVelocities(float stepTime)
{
//TODO this freezes unity FPS, so I commented out, lot of WARNINGS
/*
    // differentiate positions/orientations to get our own velocites for kinematic objects.
    // when calling Physics.Simulate, MovePosition/Rotation do not work correctly. Also useful for animations.
    if (unityRigidbody.isKinematic)
    {
        // differentiate positions to obtain linear velocity:
        unityRigidbody.velocity = (transform.position - prevPosition) / stepTime;

        // differentiate rotations to obtain angular velocity:
        var delta = transform.rotation * Quaternion.Inverse(prevRotation);
        unityRigidbody.angularVelocity = new Vector3(delta.x, delta.y, delta.z) * 2.0f / stepTime;
    }*/

    prevPosition = transform.position;
    prevRotation = transform.rotation;
}



unity 2022 throw a lot of warnings (like you can't update the velocity on a kinematic body), and FPS goes to 15-30 FPS in the editor from 80-90


so I had to comment that out. Is it okay? Or I need this one?

[josemendez]

Seems like Unity 2022 does no longer support setting the velocity of a kinematic rigidbody and will throw a warning when doing so.

Commenting this piece of code will disable CCD for kinematic rigidbodies, which depending on what you're doing might be a bummer. Will work around this and get you an alternative asap.

ok thanks, any news?

ok thanks, any news?

Sorry, I forgot about this. Please accept my apologies!!

You can find the modified scripts attached. Replace the scripts at:

Assets/Obi/Scripts/Common/Collisions/ObiRigidbody.cs

and

Assets/Obi/Scripts/Common/DataStructures/ColliderRigidbody.cs

with the ones attached, that should get rid of the warning. The workaround is basically to store our own linear/angular velocities for kinematic rigidbodies, instead of relying on Unity for this.

Should you encounter any issue with these modified scripts, please let me know.

Hi!

Newer Burst versions broke generic job compilation (in line with Unity's policy of breaking 3 features for every new one they add). This was addressed in Obi 6.5.1, in case you're using an older version I'd suggest updating to 6.5.1 since the fix/patch is not trivial to apply.

In case you're already using 6.5.1, may I ask which version of the Burst package you're currently using?

kind regards,

burst 1.8.3

I try soon with 1.8.4

[josemendez]

obi 6.5.1

That's strange, could you check whether the file located at Obi/Assets/Obi/Scripts/Common/Backends/Burst/DataStructures/ConstraintBatcher/ConstraintSorter.cs defines ConstraintSorter as:

Code:

public class ConstraintSorter<T> where T : struct, IConstraint

(roughly line 12 in the file).

burst 1.8.3

I try soon with 1.8.4

Latest Burst version that didn't exhibit this issue was 1.6. I'm not sure what the status is for 1.8.4.
