About filling the inside of the grid with color.

About filling the inside of the grid with color. Is it possible to fill multiple grids with colors?

Using only one set of grid coordinate variables (Selected Cell X & Selected Cell Y). After the old coordinate value is updated, the color in the grid (old position) still exists.

Thank you

Use an array to store selected cell positions and a for loop color them in the shader. Look up documents or tutorial on how this works in shader if you don't know how to do it. You can also encode a true or false value on a texture and sample this texture with the shader instead of using an array. The texture must have the same amount of pixels as your grid has cells inside.
