How do I smooth moving up stairs for my 3d platformer physics?

This is more of a Math question but since it uses construct features I figured I would ask it here instead of Stack Overflow...

I've built a variation on the 3d platformer example project.

It uses a similar dz adjustment system for the player's z-height, allowing them to jump/fall.

From line 38 onwards in the Player event sheet, I set a maximum height for steps, and then, when a player collides with a step, they move up onto it. The problem is, the movement is very rigid and sudden, and not natural at all. For other reasons I cannot interpolate the Z-axis as it is used for bobbing/etc.

How can I modify the player's DZ on line 44, to counter-act gravity and move up exactly four pixels before beginning to fall again?

+ Player: On collision with Platforms + Player: DZ = 0 + System: Platforms.ZElevation + Platforms.ZHeight ≤ Player.ZElevation + StepHeight + System: Platforms.ZElevation + Platforms.ZHeight > Player.ZElevation -> System: Set PlayerOldZ to Player.ZElevation -> Player: Set Z elevation to Platforms.ZElevation + Platforms.ZHeight -> Player: Set OnGround to True

Thanks!

This is too advanced for me LOL. But why don't you use Platform Behaviour instead?

3D physics are custom. Constructs platform behavior does not support 3D. :)

Nice, but I think you game is good when I try, and I don't think it is necessary to make it more smoother. You should continue the gameplay without having to think about too much detail
