Defold : Gravity and collision system in a 2D topdown game

Questions
1

Greetings everyone. Hope you’re doing well.
I’d like to ask for the Defold Engine. Is there any article where all the required elements and code are available to implement a solid gravity and collision system for a topdown 2D platformer game ?
The best game today with such system is CrossCode and it’s definitely one of the best references to showcase the features. The main things I’d need are the following :

  1. Manage to handle particle collision in such system( ideal to implement bullet physics which can simulate air movement in our context );

  2. The techniques, logic and knowledge to handle sprites sorting, jump/fly/fall movement, collision in an environment made of variable platform heights.

  3. Solving the collision problem of slopes/stairs oriented in the 8 main directions(north, south, east, west, northeast/northwest, southeast/southwest.

Note : This is not only for me, but for any curious game developer interested in the approaches to implement the system. I even recommend adding, if unexistent, Defold tutorials on this on the main website. It will be so so so HELPFUL, you can’t imagine.

Hello @tgdev001! There is no ready made articles or tutorials on this subject. I wonder if this exists for another engine? Most of the information should be transferable to Defold without much change.
