Struct CollisionMeshFile 

pub struct CollisionMeshFile { /* private fields */ }

One parsed .cmf arena component (triangles + vertices in Bullet units).

Obtain via crate::get_arena_collision_mesh_files after crate::init. get_vertices/get_indices stay in world coordinates; component_translation/make_bullet_mesh_local expose the goal-component fixup used internally at init.

Implementations

impl CollisionMeshFile

pub const fn get_hash(&self) -> u32

Hash identifying which known arena component this is.

crate::init matches it against the expected per-mode hashes and warns/skips unknown or duplicate meshes.

pub fn read_from_bytes(bytes: &[u8]) -> IoResult<Self>

Parses the .cmf binary format (u32 tri_count, u32 vert_count, then packed triangles and f32 xyz vertices, little-endian).

Errors

Returns an I/O error on truncated data; panics (debug) or mis-hashes on out-of-range indices / empty / oversized (>1M) headers.

pub fn make_bullet_mesh(&self) -> TriangleMesh

Triangle mesh in stored (world) coordinates.

pub fn component_translation(&self) -> Vec3A

Geometric goal-component test. Use the world-vertex AABB center on the Y axis. North/south goal halves center at |y| ~ 103.4 BT, past the 102.4 BT back-wall plane. All other Soccar components center at |y| <= 84.5 BT. Select only by geometry, never by scenario, tick, or triangle ID. Start with north/south only because only their transforms are proven.

pub fn make_bullet_mesh_local(&self) -> TriangleMesh

Build the Bullet triangle mesh in component-local coordinates. World vertices and hashes stay unchanged. Local equals world minus the component translation. For non-goal components this equals the world mesh. The rigid body must carry the translation so world geometry stays equal.

pub fn get_vertices(&self) -> &[Vec3A]

World-space vertices in Bullet units (see BT_TO_UU = 50 for uu).

pub fn get_indices(&self) -> &[usize]

Triangle indices into CollisionMeshFile::get_vertices (3 per tri).

Trait Implementations
