About
A hexagonal procedural world created with Unity Engine.
Description
A while back a saw a tutorial on how to make a world like this in Blender using the Geometry Nodes system, and I thought it would be a good exercise to recreate it with Unity.
Height
This tool creates the hexagon mesh and then changes its location to create a hexagonal grid. Before drawing the mesh, the height is decided with the help of the Mathf.PerlinNoise function that Unity provides, giving as arguments the hexagon's position.
Mask
An important aspect of the world is the overall shape as a hexagon, so before generating the grid, the script spawns a big hexagon that will sorround the grid. And, before spawning every object I generated a ray to check if the position is inside the hexagon mask.
Materials
To select a material for the hexagon, the script compares the height along the maximum height and with a lerp function, it maps the value with the index of a material list. Later, for the trees, the script compares the height in percentage and checks if it is between the set range.
