How to get the angle of the floor the player is standing on

What I’m looking for is the angle the movement component uses to check if the player can still stand on the current surface (What angle it compares “Walkable Floor Angle” to). So far I’ve gotten the nodes “Character Movement Component” and “Current Floor” “Current Floor Hit Result Normal” and I don’t know what to do with this.

The angle of the floor is related to the angle between “Current Floor Hit Result Normal” and the Z axis ( which is 0,0,1 ).

It’s 180 - ( the above ).

For the angle between two vectors see:
