This is a demo that showcases functionalities on an hexagonal tile grid using a cubic coordinate system.
The use of this coordinate system allows for the optimized O(1) implementation of operations such as: Distance between two tiles, all neighbors of a tile and all tiles at a distance.
This grid features 12 terrain types, being two of these mountains that feature a different elevation that are considered non-navigable tiles. For this implementation, Unity's ScriptableObjects were used, creating one for each terrain type and their respective properties.
The following functionalities are available on this demo:
- A path finding between two tiles using the A* algorithm.
- Resizing of the grid radious.
- Change the terrain type of the selected tiles.
This demo allows for interaction, implemented through Unity's new input system. The following controls are available:
- Move Camera: Mouse movement
- Select Tile: Mouse left click
- Rotate Cameta: Mouse 3
- Camera Zoom: Mouse wheel
This demo is available here!
Implemented using Unity 2021.3.9f1
