Question

我试图使用这个循环填充颜色数组然后用来设置像素，但由于某种原因我无法理解它只在某些时候工作。有时它会完美地产生纹理，有时它会混乱起来，我做错了什么？

void texRend()
{
    GameObject parentGameObject = new GameObject("SpaceStation");

    int tileRow = 0;
    int tileCol = 0;

    GameObject floorQuad = GameObject.CreatePrimitive(PrimitiveType.Quad);

    floorQuad.transform.localScale = new Vector3(stationWidth*1.28f,stationHeight*1.28f,1);
    floorQuad.transform.parent = parentGameObject.transform;
    floorQuad.transform.position = new Vector3(0.0f, 0.0f, 0.0f);

    Color transparent = new Color(0,0,0,0);

    Texture2D floorTex = new Texture2D(stationWidth*256, stationHeight*256, TextureFormat.ARGB32, false);

    Color[] floorArray = new Color[stationWidth*256*stationHeight*256];

    int k = 0;

    for(int row = 0; row < stationWidth*256; row++)
    {
        for(int col = 0; col < stationHeight*256; col++)
        {
            tileRow = Mathf.FloorToInt(row/256);
            tileCol = Mathf.FloorToInt(col/256);

            float prow = ((float)tileRow/(float)stationWidth)*scale;
            float pcol = ((float)tileCol/(float)stationHeight)*scale;

            if(roomType[tileRow, tileCol] != (int)room.None && roomType[tileRow, tileCol] != (int)room.Corridor)
            {
                int tileNumber = Mathf.Abs(Mathf.RoundToInt(Mathf.PerlinNoise(prow,pcol)*baseSprites.Length)%baseSprites.Length);
                floorArray[k] = baseSprites[tileNumber].texture.GetPixel(row%256, col%256);
            }
            else if(roomType[tileRow, tileCol] == (int)room.Corridor)
            {
                if(connections[tileRow,tileCol] == (int)connect.NESW)
                {
                    floorArray[k] = corridorFloorNESW.texture.GetPixel(row%256, col%256);
                }
                if(connections[tileRow,tileCol] == (int)connect.NS)
                {
                    floorArray[k] = corridorFloorNS.texture.GetPixel(row%256, col%256);
                }
                if(connections[tileRow,tileCol] == (int)connect.EW)
                {
                    floorArray[k] = corridorFloorEW.texture.GetPixel(row%256, col%256);
                }
                if(connections[tileRow,tileCol] == (int)connect.NE)
                {
                    floorArray[k] = corridorFloorNE.texture.GetPixel(row%256, col%256);
                }
                if(connections[tileRow,tileCol] == (int)connect.NW)
                {
                    floorArray[k] = corridorFloorNW.texture.GetPixel(row%256, col%256);
                }
                if(connections[tileRow,tileCol] == (int)connect.SE)
                {
                    floorArray[k] = corridorFloorSE.texture.GetPixel(row%256, col%256);
                }
                if(connections[tileRow,tileCol] == (int)connect.SW)
                {
                    floorArray[k] = corridorFloorSW.texture.GetPixel(row%256, col%256);
                }
                if(connections[tileRow,tileCol] == (int)connect.WNE)
                {
                    floorArray[k] = corridorFloorWNE.texture.GetPixel(row%256, col%256);
                }
                if(connections[tileRow,tileCol] == (int)connect.NES)
                {
                    floorArray[k] = corridorFloorNES.texture.GetPixel(row%256, col%256);
                }
                if(connections[tileRow,tileCol] == (int)connect.ESW)
                {
                    floorArray[k] = corridorFloorESW.texture.GetPixel(row%256, col%256);
                }
                if(connections[tileRow,tileCol] == (int)connect.SWN)
                {
                    floorArray[k] = corridorFloorSWN.texture.GetPixel(row%256, col%256);
                }
            }

            k++;
        }

    }

    floorTex.SetPixels(floorArray);
    floorTex.Apply();
    //attach texture to quad
    floorQuad.GetComponent<Renderer>().material.mainTexture = floorTex;
    floorQuad.GetComponent<Renderer>().material.shader = Shader.Find("Sprites/Diffuse");

    byte[] bytes = floorTex.EncodeToPNG();
    File.WriteAllBytes(Application.dataPath + "/../floorTexture.png", bytes);

 }

好吧，经过这么多次运行后，它似乎只在纹理为正方形时产生正确的纹理。我想我需要某种动态偏移。

原来我需要做的就是改变行和col for循环，它完美地工作！我不会期望纹理变得错误，就像那些不正确的那样。

纹理有时仅使用颜色[]进行编译
