Texture randomly generated terrain
I have generated terrain (a plane) using perlin noise and I'm trying to texture this plane using selected texture and using color map but it shows me only one color.
private Texture2D BuildTexture(float[,] heightMap) {
int tileDepth = heightMap.GetLength (0);
int tileWidth = heightMap.GetLength (1);
Color[] colorMap = new Color[tileDepth * tileWidth];
for (int zIndex = 0; zIndex < tileDepth; zIndex+=500) {
for (int xIndex = 0; xIndex < tileWidth; xIndex+=500) {
TerrainType terrainType = ChooseTerrainType (heightMap, zIndex, xIndex);
//float height = heightMap [zIndex, xIndex];
Texture2D texture = terrainType.texture;
for(int z = 0;z < 500 && z + zIndex < tileDepth;z++){
for(int x = 0;x < 500 && x + xIndex < tileWidth;x++){
int colorIndex = (z + zIndex) * tileWidth + (x + zIndex);
colorMap[colorIndex] = texture.GetPixel(x, z);
//Debug.Log(texture.GetPixel(x, z));
}
}
//colorMap[colorIndex] = terrainType.color;
}
}
// create a new texture and set its pixel colors
Texture2D tileTexture = new Texture2D (tileWidth, tileDepth);
tileTexture.wrapMode = TextureWrapMode.Clamp;
Debug.Log(string.Join(", ", colorMap));
tileTexture.SetPixels (colorMap);
tileTexture.Apply ();
return tileTexture;
}
