Public Static Functions

static MeshCollider *createFromRawData(const void *rawData, Object *obj)¶

Create a MeshCollider directly from collision asset raw data, binding to the given Object’s transform.

Borrows immutable vertices, triangles, float normals and BVH from the asset. rawData must outlive the collider (as scene assets do).

static MeshCollider *create( fm_vec3_t *vertices, uint16_t vertexCount, MeshTriangleIndices *triangleIndices, uint16_t triangleCount, Object *owner = nullptr )¶

Create a MeshCollider from manually defined geometry.

If a non-null owner Object is given, the MeshCollider’s transform will be synced to that of the owner. Coordinates must use internal physics scale (i.e. 1 unit = 1 meter). Builds the immutable triangle BVH once; geometry must not change afterwards. Ownership of the given arrays (vertices, triangleIndices) is transferred to the returned MeshCollider object; call destroyData() to free them.
