Coordinate System

This section provides a brief overview of the coordinate system used in the plugin. Both hex and square grids use an integer-based system, represented by FIntPoint. Unlike many other grid systems, MegaGrid supports negative coordinates.

Square Grid

The square grid follows a Cartesian coordinate system (X, Y). The coordinates are determined by dividing the tile's world position by GridSize.

Hex Grid

The hex grid is more complex. In most cases, including tile generation and TileData, a Doubled Coordinate system is used.

However, in some pathfinding cases, Doubled Coordinates are converted to Axial Coordinates for improved performance and accuracy. Hexagonal coordinates can be easily converted between different formats using functions in GridUtils. You can use these conversions as needed, but always revert to Doubled Coordinates when setting values in TileData or GridData.
