[Solved] Correctly scale BoxCollider

Edit:
It actually works. I did simple error along the line, during creation of BoxColliders.

Spoiler

So I have tried multiple times, and seams I am failing to scale BoxCollider.
I can not see it working, or system trying to resize, causes instant crashes.

As starting point I use samples
5. Modify / 5b. Change Collider Size
https://github.com/Unity-Technologies/EntityComponentSystemSamples/tree/master/UnityPhysicsSamples/Assets/Demos/5. Modify
Scripts / ChangeSphereColliderRadiusBehaviour.cs

There is that little Job, I based on

Spoiler

Code (CSharp):

1. private struct ChangeSphereColliderRadiusJob : IJobForEach<PhysicsCollider, ChangeSphereColliderRadius, Scale>
2.     {
3.         public unsafe void Execute(ref PhysicsCollider collider, ref ChangeSphereColliderRadius radius, ref Scale scale)
4.         {
5.             // make sure we are dealing with spheres
6.             if (collider.ColliderPtr->Type != ColliderType.Sphere) return;
7.  
8.             //
9.             // tweak the physical representation of the sphere
10.             // grab the sphere pointer
11.             SphereCollider* scPtr = (SphereCollider*)collider.ColliderPtr;
12.             float oldRadius = scPtr->Radius;
13.  
14.             float newRadius = math.lerp(oldRadius, radius.Target, 0.05f);
15.             // if we have reached the target radius get a new target
16.             if (math.abs(newRadius - radius.Target) < 0.01f)
17.             {
18.                 radius.Target = radius.Target == radius.Min ? radius.Max : radius.Min;
19.             }
20.  
21.             // newRadius = 1.5f ; // Test override
22.             scPtr->Radius = newRadius;
23.  
24.             // now tweak the graphical representation of the sphere
25.             float oldScale = scale.Value;
26.             float newScale = oldScale;
27.             if (oldRadius == 0.0f)
28.             {
29.                 // avoid the divide by zero errors.
30.                 newScale = newRadius;
31.             }
32.             else
33.             {
34.                 newScale *= newRadius / oldRadius;
35.             }
36.             scale = new Scale() { Value = newScale };
37.         }
38.     }

and line with pointer, which sets the radius.
scPtr->Radius = newRadius;

So that works

Then I had similar system, but instead

Code (CSharp):

1. SphereCollider* scPtr = ( SphereCollider* ) collider.ColliderPtr ;

I changed to

Code (CSharp):

1. Unity.Physics.BoxCollider* scPtr = ( Unity.Physics.BoxCollider* ) collider.ColliderPtr ;

Then I tried set new size

Code (CSharp):

1. scPtr->Size = new float3 (1) ;

Or 0.1f, or 2f etc. But now that Unity crashes.

I removed scaling mesh part, past line 24 for simplicity.
But no avail.

How I suppose to do it correctly with these pointers?

 

Not sure it's supported - https://forum.unity.com/threads/to-...der-radius-in-ecs-physic.722462/#post-4902029

 

Thx for a replay.

Uh. I feel a bit daft now however, as I just solved it.
I was creating Compound instead BoxCollider, which triggered few issues along the line.
I was disabling of course

Code (CSharp):

1. if (collider.ColliderPtr->Type != ColliderType.Box) return;

But nvm. It actually works
