Vector Joint

[SpiderPig]

I think Leadwerks had this... can we get this for Ultra too?

CreateVectorJoint()

Would also need to change its pin as well... something Leadwerks didn't allow from memory.

vector->SetPin(0, 1, 0)

Does the kinematic joint meet your needs? You can set the force to zero so it only handles rotation.

[SpiderPig]

I'm not sure... a kinematic joint would allow rotation on all three axis still?  A vector joint only allows rotation around the vector itself.

[Josh]

The kinematic joint would rotate the entity to whatever rotation you set. The vector joint will still let the entity spin freely around the vector if something hits it.

[SpiderPig]

Hmm, it possibly will then.  I'll try it.   I'm sure the vector joint would still come in handy though.

Alternatively if we had access to the newton world and entities bodies we could probably use newton commands ourselves.

float pin[3] = {0, 1, 0};
auto joint = NewtonConstraintCreateUpVector(world->GetPhysicsWorld(), pin, entity->GetBody())

 

[Josh]

Since all physics commands are executed on a separate thread, that would not really work.

[SpiderPig]

Ah okay.

After working with kinematic joints I think a vector constraint would better suit my needs.
