Constructor & Destructor Documentation

Mesh() [1/3]

Mesh::Mesh	(	unsigned	tilesWide = 1,
		unsigned	tilesHigh = 1 )

constructs a mesh.

the mesh is of size 1 / tilesWide x 1 / tilesHigh

Parameters

tilesWide	how many tiles wide the spritesheet is that this mesh works with
tilesHigh	how many tiles wide the spritesheet is that this mesh works with
