How to detect which CollisionObject was hit ?

[MusgooD]

I have 2 CollisionObject with the same ShapeType (for example btBoxShape)

- how to detect which of them was hit by Ray ?

Hi,

you can use the public property m_userObjectPointer in the collisionObject to store user data.

Hi pico

Thanks for reply,
Ok, i marked/customized all CollisionObjects, each object have it's own number.

But how i can get access to userdata from RayResultCallback ?

Hi,

you can access the ray result m_collisionObject.

I'm not sure why you want to know the shape. Usually people use the m_userData in m_collisionObject for a pointer to their internal game object structure.
If you just need to seperate objects you can use different filtergroups.

Thanks pico

Code: Select all

	if (resultCallback.hasHit())
	{
		return resultCallback.m_collisionObject;
	}

I get it !
