Public Static Functions

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

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

The returned collider owns newly allocated arrays (vertices, triangles, normals). Call destroyData() to free them.

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). Ownership of the given arrays (vertices, triangleIndices) is transferred to the returned MeshCollider object; call destroyData() to free them.
