How to make Slopes in 3d

How do I…

how to make 3d slopes? i dont know what to do.

What is the expected result

It should make the player realistically go up.

What is the actual result

It doesn’t go up at the right angle, its really effected by the angle and width of the slope.

I dont have anything that works even close, but there are expressions like “AngleFromX/Y” that could work.

I appreciate any help.
