Contents, API Reference, Interfaces, iMesh, positionIsValid



Returns whether or not the specified position is a valid position on this mesh.


bool positionIsValid(const cPosition& p) const;


p The position to test for validity.

Return Value

true, if the position is a valid position on this mesh, otherwise false.


All positions set by PathEngine (with positionFor3DPoint(), for example) are guaranteed to be valid or explicitly marked as invalid by having cell set to -1.
So most of the time this method is not required.
It can be useful, however, as a safety check when restoring positions from persistent store, or when working with multiple meshes simultaneously.
