One way is to turn the actor slightly and relocate the actor at the center of the circle; then turn 90 degrees and move the radial distance required from the center and un-turn 90 degrees.

Do you add the Point object into your world? You created it with this line: <Code Omitted>'getWorld' returns null on this object if it isn't in the world (so either not added at all or removed). To add it, you can use this line: <Code Omitted>

It is possible, using the setPaintOrder method in world. In the world's constructor, add something like this: <Code Omitted>You could specify the order in which they need to appear, the first one being the type that will be displayed on top of following ones, but if I'm not mistaken, specifying only one class will ensure it will get drawn on top of all the others.
I'll tweak around with this and look more into it if needed. Thank you.

I'm working on a space shooter game, where the attackining space ships, who are coming down to the player's ship, are getting faster and faster. So the degree of difficulty increases but not to fast.
To slow down the speeding up of the space ships, you could do something like this: <Code Omitted>(have the value of 'i' start at the slow down value)
