How can I detect if my object is walking up or down a hill OR slope?

If the Y coordinate is increasing then it is going up.

Not neccessarily. If my character was a bird, that would increase the Y-Coordinate as well. I need something like maybe a formula AND / OR function. PREFERABLY, a function to detect if a character is walking up or down a hill / slope, OR is walking left / right / diagonal on a hill / slope

Check the collision normals. CollisionNX() NY() NZ(). They will tell you the normals of the current collision.

as Floyd said, but you can check if the object is grounded also by comparing it's Y coord with the height of the terrain at that object's x,y coords. TerrainHeight# ( terrain,grid_x,grid_z )
