OimoPhysics 1.2.2x (Forked)

A lightweight 3D physics engine.

INFO

This is as special forked version of OimoPhysics, that is adapted to suit the needs of the FUDGE Project. This can result in very niche changes, like supporting old ways of javascript moduling etc. I'm adding only what is needed by that project and if the original creator decides to update i try to merge those changes into this.

The fork is continuing the work of adapting to Haxe 4.0 and is compiled with Haxe 4.1.5. So this Master branch is actually a continuation of the dev branch. Currenty Added Features:

• Trigger/Ghost Rigidbodies - Behaves like any other Rigidbody but does not play any part in collisions. Trigger Rigidbodies send a special event/callback for triggerEnd/triggerBegin It is done by calculating all necessary collisions but throwing them away in the actual solving step. Issue #34
• Fixed Shape can't be removed/readded without error Issue #33

Demos

Platforms

• Written in Haxe
• Exported as JavaScript (see bin/js/)
  • Public classes and methods are exposed through window.OIMO.
  • e.g. new OIMO.Vec3(1, 2, 3) to create an instance of Vec3 class.
• Exported as JavaScript (module) with TypeScript Declaration (see package.json and bin/js_modules)

Compilations

Haxe 4.0.0 or later is required. (recommended: Haxe 4.0.5 or later)

• Use build-js.hxml to compile for JavaScript library.
• Use build-js-demos.hxml to compile JavaScript demos.
• Use build-doc.hxml to generate API documentation. dox is required.
• Use build-js-ts.hxml to compile for JavaScript (modules) library with TypeScript declarations. Requires hxtsdgen library. Check comments in that file.
