Detailed Description

Entity coordinate types.

The basic unit is the "meter". Terrain tiles are TERRAIN_TILE_SIZE (=4) meters square. To support deterministic computation across CPU architectures and compilers and optimisation settings, the C++ simulation code must not use floating-point arithmetic. We therefore use a fixed-point datatype for representing world positions.
