Is there any way to access physics calculations beforehand?

Question

I have more than just a few PointEffector2D components in my scene and I want to see what path a projectile would take in t$$anonymous$$s minefield of effectors.

How would I go about it for pre-calculation of a projectile?

In case I'm not clear on t$$anonymous$$s, I want to pre-calculate a path like t$$anonymous$$s and show it to the player: alt text

From the docs:

Physics2D.GetLayerCollisionMask & Physics2D.SetLayerCollisionMask

those are for accessing the collision masks. I'm asking how to access the global collision matrix itself (the physics matrix which affects all the rigidbodies).

I wrote the 2D physics stuff so trust me when I say this is it.

The Physics2D is the global physics control. These two methods provide access to the pseudo matrix as displayed in Physics2D settings.

Each layer has a respective layer-mask which controls which layers it interacts it.

I've reworded the question and omitted that part. I'm not sure why the docs refer to a global collision matrix if it's just the same thing as the layer collision matrix.
