Dev Blog - Building System

Hi Everyone !

Here again a small progress-update about Rokatusch.
Notice: Since the workers are controlled by AI (Artificial intelligence / Computer player), there are some delays between the actions (Running, cutting trees and building buildings),

What's going on?

I updated the building process. Grass and other environment details (Stones, flowers, ...) at building will be removed from now on.
Food production building was added too.

What's next?

I will work on the resources logic next.

How does grass removing work in Unity

// Removes details of terrain [layer] at [position] for size [halfExtendWorld] (Half extended quad in world size)
private static void RemoveMapDetails(Terrain terrain, Vector3 position, float halfExtendWorld, int layer = 0)
{
var detailWidth = terrain.terrainData.detailWidth;
var halfDetailWidth = detailWidth / 2f;
var factor = detailWidth / terrain.terrainData.size.x; // Calc factor for detail map resolution

var targetX = (int)Math.Round((position.x * factor) + halfDetailWidth, 0, MidpointRounding.AwayFromZero);
var targetZ = (int)Math.Round((position.z * factor) + halfDetailWidth, 0, MidpointRounding.AwayFromZero);

var halfExtend = (int)Math.Round(halfExtendWorld * factor, 0, MidpointRounding.AwayFromZero);

var startX = targetX - halfExtend;
var startZ = targetZ - halfExtend;

var map = GetMapData(terrain, layer);
var maxZ = map.GetLength(0);
var maxX = map.GetLength(1);

for (var z = startZ; z <= targetZ + halfExtend; z++)
{
for (var x = startX; x <= targetX + halfExtend; x++)
{
if (z < 0 || x < 0)
{
continue;
}

if (z >= maxZ || x >= maxX)
{
continue;
}

map[z, x] = 0;
}
}

SetMapData(terrain, map, layer);
}

private static int[,] GetMapData(Terrain terrain, int layer)
{
return terrain.terrainData.GetDetailLayer(
0,
0,
terrain.terrainData.detailWidth,
terrain.terrainData.detailHeight,
layer);
}

private static void SetMapData(Terrain terrain, int[,] mapData, int layer)
{
terrain.terrainData.SetDetailLayer(0, 0, layer, mapData);
}

Otherwise nice day and greetings
