bool Boole
Generally acts a single bit, true or false.
Definition: datatypes.h:173
All the definitions for datatypes as well as some basic conversion functions are defined here...
CollidableProxy * ProxyB
The second world object in the pair.
CollidableProxy * ProxyA
The first world object in the pair.
This is a helper class for storing pairs of collidable proxies in associative containers.
This is a proxy from which physics objects that can collide with each other are handled.
uint64_t UInt64
An 64-bit unsigned integer.
Definition: datatypes.h:130
#define MEZZ_LIB
Some platforms require special decorations to denote what is exported/imported in a share library...
The bulk of the engine components go in this namspace.
