How to rotate the pawn based on a intersection of his ground plane with the mouse ray in BP?

C++ code reference from our other engine.

Steps:

  1. Get the current Pawn
  2. Create a plane using Pawn origin
  3. Shift the plane Y position by a variable (Ex: Half the player cylinder)
  4. Get mouse X,Y and project a ray in the plane
  5. Use the position and calculate a rotation vector
  6. Apply the rotation to the Pawn

If you can provide a BP print like the below its better.

The accepted answer will populate on a tutorial at the Wiki.

Just an assumption, since I don’t have the time to recreate it right now, I’m gonna assume you graph is debugged and your ray casts works correctly:
Since it’s top down, you should probably get the “Roll” instead.

Hi Darion.
I am using a rotating record. In my game it is an actor. I am following this example because it is relevant to breaking its rotation and allowing mouse interaction with the record on the platter. Should I start over and create a pawn that is a record or can the same principle apply to an actor? (Noobish confusion)
