bjorn 0f2717850e Collider shape is required I think; 
Jolt doesn't really support bodies without shapes.

bjorn 8e0aceadbf World queries return collider/shapeindex instead of Shape; 2024-04-05 11:29:26 -07:00
bjorn 1998439083 Require frozen CompoundShapes to have at least 2 children; 
If you create a StaticCompoundShape with 1 child, Jolt creates a
RotatedTranslatedShape.  It would be a pain to have to branch on that,
so let's just require 2 children.

bjorn efba985973 rm Shape setters; 
Jolt doesn't support this and requires you to recreate the shape.  Since
the shape -> collider relationship is 1:N, we can't really create a new
shape because we'd have to figure out which colliders/compoundshapes to
assign it to, which isn't feasible.

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 cdecc1bae7 Add defer system; Rework exceptions; util cleanup; 
Defer can be used to clean up resources when an error occurs.

bjorn b7e1b5111e jolt: fix some shape memory leaks; 2024-03-29 15:26:10 -07:00
bjorn c5d6bb6b48 jolt: rm matrix copies; 
JoltC now uses floats for its RVec/RMatrix structs in single precision
mode, so we can operate on them as mat4's directly, copy/cast them, etc.

Josip Miskovic 47c9b20542 Jolt world-level damping and sleeping allowed 
The damping 0.05 value comes from Jolt's BodyCreationSettings.h.

Josip Miskovic 431062c345 Increase Jolt body & constraint limits 
The new values come from comments in the official HelloWorld.cpp. After
the changes the any increase of memory consumption is within the
measurement error.
