Question Yet another constraint problem

I've tried to use google to find the answer to this, but I keep finding several different 'answers'. I want to constrain my player on the Z, and its rotation. From what I've seen I've created this script:

Code (CSharp):

1.  public sealed class PhysicsConstraint : MonoBehaviour, IConvertGameObjectToEntity
2.     {
3.         public bool3 Linear = new bool3();
4.         public bool3 Angular = new bool3();
5.  
6.         public void Convert(Entity entity, EntityManager dstManager, GameObjectConversionSystem conversionSystem)
7.         {
8.             var entityA = new RigidTransform(
9.                 dstManager.GetComponentData<Rotation>(entity).Value,
10.                 dstManager.GetComponentData<Translation>(entity).Value
11.             );
12.             RigidTransform entityB = new RigidTransform(float3x3.identity, float3.zero);
13.  
14.             PhysicsJoint joint = default(PhysicsJoint);
15.             joint.BodyAFromJoint = entityA;
16.             joint.BodyBFromJoint = entityB;
17.             joint.JointType = JointType.Custom;
18.             joint.SetConstraints(new FixedList128<Constraint> {
19.              new Constraint
20.                 {
21.                     ConstrainedAxes = Linear,
22.                     Type = ConstraintType.Linear,
23.                     Min = 0,
24.                     Max = 0,
25.                     SpringFrequency = Constraint.DefaultSpringFrequency,
26.                     SpringDamping = Constraint.DefaultSpringDamping
27.                 },
28.                 new Constraint
29.                 {
30.                     ConstrainedAxes = Angular,
31.                     Type = ConstraintType.Angular,
32.                     Min = 0,
33.                     Max = 0,
34.                     SpringFrequency = Constraint.DefaultSpringFrequency,
35.                     SpringDamping = Constraint.DefaultSpringDamping
36.                 }
37.             });
38.  
39.             PhysicsConstrainedBodyPair pair = new PhysicsConstrainedBodyPair(entity, Entity.Null, false);
40.  
41.             dstManager.AddComponentData(entity, joint);
42.             dstManager.AddComponentData(entity, pair);
43.         }
44.     }

When I move around, for the most part, this works. However, if I snag on a box it will force my player to move in the Z axis.

 

I removed the second entity part, and it kinda works. But I am still able to move the player in the Z-axis

Code (CSharp):

1.     public sealed class PhysicsConstraint : MonoBehaviour, IConvertGameObjectToEntity
2.     {
3.         public bool3 Linear = new bool3();
4.         public bool3 Angular = new bool3();
5.  
6.         public void Convert(Entity entity, EntityManager dstManager, GameObjectConversionSystem conversionSystem)
7.         {
8.             var entityA = new RigidTransform(
9.                 dstManager.GetComponentData<Rotation>(entity).Value,
10.                 dstManager.GetComponentData<Translation>(entity).Value
11.             );
12.  
13.             PhysicsJoint joint = default(PhysicsJoint);
14.             joint.BodyAFromJoint = entityA;
15.             joint.JointType = JointType.Custom;
16.             joint.SetConstraints(new FixedList128<Constraint> {
17.              new Constraint
18.                 {
19.                     ConstrainedAxes = Linear,
20.                     Type = ConstraintType.Linear,
21.                     Min = 0,
22.                     Max = 0,
23.                     SpringFrequency = Constraint.DefaultSpringFrequency,
24.                     SpringDamping = Constraint.DefaultSpringDamping
25.                 },
26.                 new Constraint
27.                 {
28.                     ConstrainedAxes = Angular,
29.                     Type = ConstraintType.Angular,
30.                     Min = 0,
31.                     Max = 0,
32.                     SpringFrequency = Constraint.DefaultSpringFrequency,
33.                     SpringDamping = Constraint.DefaultSpringDamping
34.                 }
35.             });
36.  
37.             PhysicsConstrainedBodyPair pair = new PhysicsConstrainedBodyPair(entity, Entity.Null, false);
38.  
39.             dstManager.AddComponentData(entity, joint);
40.             dstManager.AddComponentData(entity, pair);
41.         }
42.     }

 

If anyone cares, I wasn't moving the body by physics. Hence why nothing was working. So this became a rubber ducky moment.
