One of the big benefits of developing with GameMaker: Studio is that it has an in-built Image Editor for creating sprites and backgrounds. This editor may appear to be very basic but there are a lot of excellent tools available to use. There are a variety of different drawing tools including the standard tools such as pencil, eraser, and fill. One very useful and unique feature in the editor is the ability to paint with both mouse buttons. The Colors | Left and Colors | Right color options, as seen in the following image, indicate the color that will be used depending on whether the left or right mouse button is being used. We can also adjust a wide range of things through the Transform and Image menus. The Transform menu contains the ability to affect the size and placement of the pixels in the image. The Image menu contains the image alteration tools such as the ability to change the color, blur the image, and add glows.
