Ammo Physics (3D Physics Extension)

[Brackets-Coder]

A work-in-progress extension based on the ammo.js physics library, which is based on the C++ Bullet Physics SDK.

The goal is to provide feature-complete, advanced, and performant 3D physics in a simple-to-understand manner. This extension aims to be consistent with Box2D and Simple3D.

I expect several more months of work before this is ready for release, but I'm putting a Draft PR here just because I can :)

Task list:

• All shape types:
  • Boxes
  • Spheres
  • Cylinders
  • Cones
  • Capsules
  • Planes
  • Convex Hulls
  • Triangle Meshes
  • Compound bodies
• Physical Materials (friction, restitution, etc.)
• Constraints (All types)
• Collision:
  • Collision Detection
  • Raycasting (partial support)
  • Enable/disable collision response
• Manual Impact forces (like "push with force" block in Box2D)
• Player Management?
• Vehicle support?
• Soft bodies?

Miscellaneous Notes Mainly for Moderators:

• I'm trying to take a more object oriented approach that's more professional, hope this one is easier to review than my previous extensions.
• ChatGPT was used to assist and enhance the making of this extension, simply because I couldn't find good quality, coherent documentation of Ammo.js, and attempting to figure out how to use it via the developer inspector isn't fun. It did not write the code for me and I am still the main author of this extension. It just helped me learn Ammo.js. Hope this doesn't cause conflicts.
• It includes multiple large (but minified) libraries... hope this isn't a problem
• Has some weird (but necessary) ESLint workarounds for Ammo initialization. Also hope this isn't a problem.
• I can't decide if this should go by Simple3D or Box2D in the gallery. If a moderator could give me some advice that'd be great. I put it by Box2D because they seem to fit into similar categories.
• I haven't made documentation, sample projects, etc. yet
• I'm not good at graphic design so if someone wants to make a banner/thumbnail that'd be great
• Still have to incorporate Scratch.Cast where necessary, right now I'm just working on functionality though

Wow! It's very cool and useful for people like me)

Thank you! I've been making steady progress, but it probably won't be ready for a while (which is why this is a draft).

Added partial support compound bodies - all child shape types.
Also working on convex and concave mesh support... it'll be a while.

wow

Finally got convex hulls working 🥳 🎉

Still have to optimize and bug fix everything and add more features
