Not sure whats good for pixel platformer collisions that supports slopes, consistent and not janky…

I’m new so I’ve been following this tutorial and used tilemap collisions:

> **[Platformer Defold tutorial](https://defold.com/tutorials/platformer/)**
>
> In this article, you go through the implementation of a basic tile-based 2D platformer in Defold. The mechanics you learn are moving left/right, jumping and falling.

EDIT:  
Nevermind. Best solution I found was utilizing raycasting instead of basic shape colliders. I followed and tried transfering this Unity tutorial series into Defold since Unity is pretty similiar to Defold in a way.
