For an entity position, Vector3d. For a chunk coordinate, cChunkCoords. + - For a 3-dimensional box of blocks, use cCuboid. For an axis-aligned bounding box, use cBoundingBox. + * Parameters smaller than 4 elements (e.g. Vector3, cChunkCoords) should be passed by value. All other parameters should be passed by const reference, where applicable. + - `Foo(Vector3d a_Param1, const cCuboid & a_Param2)` + - See the discussion in issue #3853 * Put spaces after commas. `Vector3d(1, 2, 3)` instead of `Vector3d(1,2,3)` * Put spaces before and after every operator. - `a = b + c;` |
