public void SetPixel(int x, int y, Color color, int mipLevel = 0);


x X coordinate of the pixel to set.
y Y coordinate of the pixel to set.
color Color to set.
mipLevel Mip level to sample, must be in the range [0, mipCount[.


Sets pixel color at coordinates (x,y).

Call Apply to actually upload the changed pixels to the graphics card. Uploading is an expensive operation, so you'll want to change as many pixels as possible between Apply calls.

If you're constantly regenerating a texture at runtime, it may be faster to generate an array of pixel colors and set all of them at once with SetPixels.

This function works only on RGBA32, ARGB32, RGB24 and Alpha8 texture formats. For other formats SetPixel is ignored. Texture.isReadable must be true.

for (int y = 0; y < texture.height; y++) { for (int x = 0; x < texture.width; x++) { Color color = ((x & y) != 0 ? Color.white : Color.gray); texture.SetPixel(x, y, color); } } texture.Apply(); } }
