how do i make a sprite-based level generator?

hello, I was trying to make a system in which the programming reads the color of the pixel and according to the color it creates an object in that location, but I couldn't. Can someone help me?

That's probably not a good idea since it takes a tick to read the color from single pixel in Drawing Canvas, which is the only object that can do that.

Making a list using one of the data type objects would be far faster.

If you need a visual representation the Tilemap object would work if you go by tile index.

I saw here that the drawing canvas is only for c3, is there any other way to do it by construct 2?
