I have mad a physics engine that is mostly designed so that it’s easy to make custom collision shapes! Here’s the link to my demo:

If you want to use this as a base to a game, you can, just make sure to credit me on the physics engine.

This has to be one the most impressive slope physics engine Ive seen on the forums! It seems specific but a fair amount of people have tried it before 🤣

By the way, the physics engine isn’t _just_ for slopes, it can do _any_ shape, so long as it can be made in a 16x16 grid.

Wow!!! I have seen physics engines but only using extensions, and they are so laggy. This game is definitely the most impressive slopes I have seen. Perfect for an infinite runner game 👀

the fact that this is spriteless as well is incredible, well done!

Its even got semi-solids? Wow.

I will admit, the semi-solids are a little buggy.

I must agree! so many slope engines are hard to compare this to! the fact that it goes up by the pixel, wow!

You should make it into an extension. This is the best slope engine I have seen by far!

Sorry, I only really know how to do block coding. If I could make an extension, I would, but I don’t understand how to.

you can make your functions in block and then go into js and copy that code and format it into a extension function, heres something to help u, [Makecode Playground](https://makecode.com/playground)

I could do it if you want

Here’s a new update on the physics engine! I have added ice and also fixed up the bug with the semi-solids I had mentioned yesterday! Here’s the link:

Wow this is awesome!!! Can the ice be a bit more slippery? As in, you just keep moving with little to zero friction?

The new ice is great, but i feel like you should slide down the ice slopes when standing still. I have no idea how such code could be written but it just seems right

Is this better?

Very nice, one of the best I’ve seen. Now go and make it so that you can groun pound through the semi solids

Perfect!!! Seriously this is one cool engine!
