Orkuncakilkaya b4af12025d physics: Jolt's floor sized for what moves - pairs 4096, contacts 2048 and a 4 MB temp heap by default (phys_open_sized for more), and a body past max_bodies or a step past the pairs or contacts is Mem.over, never a quiet -1; world.ludic split from shapes.ludic 
An empty world at the game's size held 51839 KB of Jolt's heap (200000 bodies, 65536 pairs, 20480
contacts, a 32 MB temp heap), the jolt= floor under every walk. Pairs and contacts come from what
moves - drops, boats, a few walkers - and a valley's still things make none. Now 11743 KB at 200000
bodies and 8461 KB at the 98304 the game opens for (jolt_floor_test holds it under 16 MB). The temp heap
still falls back to malloc for a step that wants more.

lib/macos-arm64 rebuilt; lib/windows-x64 needs native/build.sh on the PC (jph_world_new's new sizes).

jph_alloc.inl feat(ludic.physics): Jolt's heap counted in the shim (plan 25) - jph_heap_bytes/peak/allocs, phys_heap_bytes/peak/allocs 2026-09-28 15:49:38 +03:00
jph_bodies.inl feat(physics): a walker (Jolt CharacterVirtual with an inner body) and the verbs a boat and a guest's copy need - force, torque, angular impulse, spin, set_pose 2026-09-27 00:24:47 +03:00
jph_character.inl feat(character): 16.8 - on land a physics walker moves the body (CharacterGround.walk); the package's own gravity, ballistic air and slope-probe refusal are gone 2026-09-27 00:47:14 +03:00
jph_queries.inl fix(physics): push keeps the old collider contract exactly - a thing wholly under the feet or over the head is not in the way, anything else pushes out sideways (Jolt's axis when side-on, else radially by the overlap across) 2026-09-27 00:08:36 +03:00
jph_shapes.inl feat(physics): 16 - a rock's own shape: phys_convex (Jolt's convex hull of a point cloud) and phys_scaled (one hull, every rock of that shape at its own size); the libraries rebuilt on the Mac and the PC (still KERNEL32 alone); hull_shape_test holds the scale and that a yaw turns a body the way a renderer turns an instance 2026-09-27 15:22:30 +03:00
