thank you

That worked, when I update the Information in act, it works, thank you

As far as I know, Greenfoot only uses one. Each act cycle, the act method of the active world and the act methods of all actors inside that world are executed one after the other.

Replace line 43 with: <Code Omitted>

What have you tried? Unclear what you want exactly. "when it drag to mouse coordinates" makes no sense at all. Giving some attempted code goes a long way in clearing up any misunderstandings and gives needed context to anyone who is willing to help. It also usually gets your issue resolved in a much shorter time.

Ok, now I understand it. Thank you

thanks :-)

thank you

oh thank you very much

Thanks :). Now both pipes dont move, just rotate and only one shootkey works, which triggers both pipes

Yeah, I fixed it by myself thanks. Eventhough it wont even start to shoot and the conosle is being opened as I push a shootkey

Both your facingEdge and facingThing methods have a boolean (true/false) return type. You cannot exit either of these methods without returning a boolean value. Either: <Code Omitted>or <Code Omitted>The value returned can be an expression that results in a boolean value. Some examples of expressions resulting in a boolean value are: * isAtEdge() // method with a boolean return type (state) * getIntersectingObjects(Actor.class).size() == 0 // comparison * Greenfoot.mouseMoved(null) && !Greenfoot.mouseMoved
