Legacy GM What is the most efficient method of angle calculation

Hello,

I'm trying to make a sonic like platformer. I would like the player to dynamically change according to the angle of the ground. I don't know what would be the quickest method. I don't want to use the small object/angle variables method because I feel that would become cumbersome and lengthy so i would like to be able to draw the object and find the difference from that point.

Assign a value to each terrain element. When the player's center point is over the tile, use the assigned value to determine what angle the player should be at.

For example:

Code:
0 0 5 4 4 3 0 0
0 6         2 0
0 6         2 0
0 0 7 0 0 1 0 0
If terrain_value is 0, set onLoop to false and image_angle to 0.
If terrain_value is 1 and image_xscale is 1, set onLoop to true.
If terrain_value is 7 and image_xscale is -1, set onLoop to true.
If onLoop is true, set image_angle to 45*terrain_value.

So each of those values is a different object?

Or if you use tiles, different tile... I mean, it's all the same concept. You just find out what tile/object/whatever the player is over, then use that to look up or calculate how to make the player move and angle. It's faster than calculating the shape of the ground

So for that method each object would have to have a particular angle value assigned to it correct?
