There are many Snake projects on this page and also some of them are with-source. It would be the easyest way if your could just look at this scenarios and see how they've done this.

A simple question! Please answer.

Set speed doesn't set the speed of only one class but of whole Greenfoot. so if you say Greenfoot.setSpeed(35); and then Greenfoot.setSpeed(15); Greenfoot will only use the second of this values. Also in the botom right of greenfoot there is a scrollbar to set Greenfoots speed.

The nullPointerException error...

By Stormtrooper299, with 10 replies.
Last reply by davmac, almost 13 years ago:

But does that still have the same problem?

Yes, because if Enemies.main is null the call to Enemies.main.getWorld() causes a NullPointerException. However, you can simply change the order: <Code Omitted> In this version, due to "lazy evaluation", if Enemies.main is null then Enemies.main.getWorld() will not be evaluated.

I would be very grateful. http://www.greenfoot.org/scenarios/6773 This is how i did it.

How can I create red brick square on greenfoot?

By Future, with 1 reply.
Replied to by danpost, about 13 years ago:

We could say that the code to get a square/rectangle is built into the GreenfootImage of the Actor. Each actor has an 'image' which IS a rectangular area. Within the bounds of this rectangle is where the image of the actor appears. You only need to create a GreenfootImage object of appropriate size and draw along each edge the image of the brick (just program it to draw one edge, then rotate the main image to continue drawing the brick image around all four edges).
