rect block will plot a square at the x and y coordinates it is given. The x and y coordinates tell it where the top left corner of the square goes in the display area.
ellipse block will plot a circle at the x and y coordinates it is given. The x and y coordinates tell it where the center of the circle goes in the display area.
In order to plot things on the screen in Game Lab, you will need to use x and y coordinates. The x coordinate tells how far something is from the left side of the display area. The y coordinate tells how far something is from the top of the display area.
fill block changes the color that Game Lab uses to color in the shapes you draw. Once you use the
fill block, all the new shapes you draw will be filled in with that color, until you use the
fill block to change the color again.
Game Lab understands most common color names, such as "red", "green", and "brown". It also understands all the HTML Color names listed at HTML Color Names - W3Schools.
