Detailed Description

Texture slot objects.

The texture slot objects expose the data structures used to organize geometry texture information and encode it in a level. A vector containing a series of slot objects is associated with every cube object, allowing every cube face to reference a slot "palette" containing many texture + shader combinations without requiring much data stored on the client.

Furthermore, a VSlot object is defined, which defines a virtual texture slot. These are derived from a "real" texture slot, and can have one or more shader modifiers applied to it: color, scale, rotation etc.

anonymous enum

Bitmask variables for a VSlot.changed field.

These variables determine what about a virtual texture slot has been changed. Use them by bit shifting by the value of the enum, e.g.

slot.changed = 1 << VSlot_ShParam;
