Line Following Demo

This is a demonstration of having an actor follow the edge of a specific color in the background of the world, or turn at specific colored dots. The color in this demo is 'blue'.

There are two view in this demo (shape view and dot view). Click on the 'dot view' object at the top-left corner of the screen to switch views.

In dot view: the actor will be guided by the one-pixel by one-pixel blue dots in the background of the world.
In shape view: the actor will, once moving onto a blue point, turn and follow the edge of the blue around the shape. You have two extra bars in this view to change the thickness of the diagonal lines drawn on the background. They are located in the top-right corner of the screen.

There are two other bar objects located in the top-left corner: one controls the method of movement (4-way or 8-way); and the other will change the 'hand' the 'follower' uses to follow the edge of the color in the world (essentially, changing the direction of movement). A third bar was added for controlling the speed. Click or click and hold in various places of the bar to see how it works.

In shape view, the thick blue ovalish shape is drawn first; then the black line; and finally, the blue lines.

The dot view was thrown in as an extra, to demonstrate the movement control gained by them using the same movement methods.
