Laser should NOT extend Player (a laser is not a player). Your line of code should get x and y from player, not from the image of the player.

Customers (Diner Dash)

By APCSP-6, with no replies.

I need to create character to act as the customers for my Diner Dash game, but I can't seem to find any to work anywhere. Is there any way that I could take two actor people from Greenfoot and put them together. Follow-up is there any possible way that I could get them to sit and stand... and move? If that makes sense.

I figured it out! When I declared theFog to make it so that I could call Fog from another object, I didn't input <Code Omitted> which returned an error because it was trying to call something that didn't exist!

Random number generator influencing "isKeyDown"

I want the output of the generator to be saved as a sting not an integers.

An int value can be converted to a String representation of that value at any time using ""+intValue

The blankclass will never be in the world. It's just so that both the input indicators and the player can inherit from it.

You still need to create one, nonetheless, for any random values to be generated. Also, nothing prevents two random values being the same.

i placed a sound effect when an actor does an act and the sound seems to be playing over and over again while the actor is doin that act. i only need it to play once. for example when i shoot the sound wont stop until the shot disappears from the world

Instead of using Greenfoot.playSound, maintain a GreenfootSound object and play it when needed.
