Counter for lives not incrementing or decrementing.

Strange. After doing a bit of debugging, I found that bombBoom never returns true; it's always false, even when the bomb hits it. Is it supposed to do that? I would like to use this for my lives system, whenever the bombs hit the boomArea (bombBoom is now true. False is when the bomb is in the air falling down.)

Just fixed it as of now. The problem was that boomBoom was being called in the act method of boomArea.

I added bullet code to my character but I don't know how to make my character shoot in the direction of which my character is facing. I have tried about anything on the internet but nothing seems to work. << Code Omitted >>

The rotation of your Soldaat actor never changes;, so getRotation() will always return zero at line 32. Bullet on line 32 is a Class

Is it possible for the wombats to move diagonally? << Code Omitted >>

You would need to change line 48 to: <Code Omitted>and add the appropriate cases to the switch block in the canMove method. However, once an edge is reached, it will turn twice to go along each edge, anyway. Maybe adding a random turn to the code would help: <Code Omitted>

Variable from MyWorld

By JPEG, with 3 replies.
Last reply by danpost, over 7 years ago:

I'm not sure how, but I treat my actors like Variables. ... how do I figure out what case random has been assigned to? e.g If random followed case 2 (as I already said that the actor paper has to be pressed), the IF statement will mean that scissor's actor will be removed.

Place your actors in an array field: <Code Omitted>They will each now have a number associated with them: <Code Omitted>Your act method can then start wit

You meant the GameScene and not the TitleScreen right? << Code Omitted >>

Yeah. I wanted to see what it does for its extensions. It is not a cause of your current concern; however, I do not really see a need for the class (it actually creates and plays multiple instances of the bg music -- one for each time an object is created for it or any of its extensions). Let us start afresh -- back to your originally posted code (w/o any of the changes I previously suggested) and think about this logically. You start with a TitleScreen object. Fine -- let

They end up in a traffic jam that's the problem .

Well, they will be either on top of each other (fully or partially) or not. You cannot have it any other way.

Smooth movements

This: <Code Omitted>from the nachrechts method, is equivalent to this: <Code Omitted>A similar thing can be said for the loop in the nachlinks method. Instead of Position values of 0 and 1, it would be better to have Direction values of 1 and -1. Also, instead of a constant verschiebung value, you can have it decremented to zero during a move (setting it to 88 when a move is initiated). The multiple similar if statements can also be simplified. You woul

How to use mousePressed?

I don't understand how to use the Greenfoot.mousePressed command. Like what do I have to put in the brackets? I know that I have to put the object but how do I write it?

The Greenfoot class documentation says this:

Parameters: obj - Typically one of Actor, World or null

Most of the time, it will be 'null', meaning any click anywhere, or 'this', referring to the object, created from that class or one of its subclasses, that the current block of code is being executed on (or for). If not one of those, it will be a named reference to an
