Actor removeFromWorld()

By MrBradley, with no replies.

Has any thought been given to the possibility of adding a removeFromWorld() method on Actor? This would be similar in purpose to the addedToWorld() method that allows some customization. In removeFromWorld, it allows for the opportunity for an Actor to take some appropriate action. At the least, the instance would be notified of an imminent removal. If this has been considered in the past, what was the reasoning for not adding it? Thanks, Mr Bradley

Did you put the code into the act method? If this is already the case, make sure you don't remove the object from the world before this code is executed.

Help with wait() method in greenfoot!!

By Venbha, with 4 replies.
Last reply by danpost, over 9 years ago:

The 'wait' methods of the Object class are thread operations which are not intended to be used with greenfoot. Greenfoot provides the act method, which can be used to control when an object does anything (which is the same as when it is not to do something, or anything)..

Not sure why pacman ends in a wall, but the error message happens in the Level class, so you have to show this class.

Ability Cooldowns

Sounds like you could use something like a bar type object (similar to a health bar in appearance). Only, this bar will either increase or decrease with time and the ability will be reusable when the time has expired. You can check out my Value Display Tutorial scenario to see how to create a bar object (or other type object that can display your timer). If you cannot access it, you can also find the tutorial here. I do have a Bar support class that you could use. It is

Nothing, you only need to add a Timer object into the world. Well, you need Greenfoot version 3.1.0 or you need to import the java.awt Color and Font classes.
