bjorn 15649802c8 Rework World Collider/Joint lists; 
- Add World:getColliderCount
- Add World:getJointCount
- Add World:getJoints
- Add Joint:isDestroyed
- Destroy joints when either of their colliders are destroyed (Jolt
  seems to require this).
- Fix joint memory leak.
- Change joints to be stored in some crazy graph thing.
  - Reduces allocations, allows constant time insertion/removal.

bjorn 98601b3425 Collider:setShape accepts nil; 
Internally it still uses a teeny tiny sphere (it's kinda like the
collider's shape is a "point").

bjorn b589cec975 Collider:getShape takes optional child index; 
For convenience when you're trying to dig a leaf shape out of a CompoundShape.

It's ignored if the collider's shape is not a CompoundShape.

bjorn 5751068728 Move Shape:is/setSensor and Shape:is/setEnabled to Collider; 2024-04-07 13:47:52 -07:00
bjorn 907d89c913 Add Collider:getShapes for backcompat; 2024-04-07 13:47:52 -07:00
bjorn 051266f8ea Collider shape is required I think; 
Jolt doesn't really support bodies without shapes.

bjorn fdba60214c Fix Collider/Shape/Joint UserData leak; 
refs are cumbersome because they require storing an int and they require
manual cleanup when the object is destroyed.

Instead, we'll go with a pure Lua solution using a table in the
registry.  The table has weak keys containing the LÖVR object, and the
values are the userdata.  This doesn't require any manual cleanup,
reduces the size of objects by 8 bytes, and is about 25% faster.

bjorn be795c0ebd Change vec3 back to 3 floats; Clean up maf/vectors; 
The "vec3 is 4 floats" thing was consistently confusing to people.  It's
reverted everywhere except for Curve.

maf now has full sets of methods for vec2/vec3/vec4, for consistency.

Vector bindings now use luax_readvec* helper functions for the
number/vector variants, and use maf for most functionality, which cleans
things up a lot.

bjorn e9776f98c6 Fix compatibility with Lua 5.2, 5.3, 5.4; 
Part of this involved putting the Lua header back in api.h, since we
need to know the Lua version to define some macros properly.

bjorn 8fcdfd2bb4 Minor physics cleanup; 2022-03-30 22:05:10 -07:00
bjorn 159243190b rm some unnecessary includes; 2021-04-20 20:08:30 -06:00
bjorn e63099ba6a Flatten api.h; 2021-03-15 18:54:27 -06:00
bjorn 3bc2c00b79 api doesn't include util; 2020-12-25 12:50:26 -07:00
Josip Miskovic b4d391f45f Change default damping threshold to zero 
Zero as default makes more sense. Colliders can come to full stop which
allows them to go to sleep for CPU optimization. Also in zero gravity
colliders crawling through air with 0.01 velocity are infuriating.

Josip Miskovic a4b0d004a1 Fix collider setOrientation() and setPose() 
The conversion from angle,ax,ay,az to quaternion is already done in
physics module.

bjorn c9b1f257bf api: try new file naming convention; Tupfile: cleanup; 
I assume full responsibility for any catastrophes this causes.
