HELP ME PLEASE :)

Ok so a really simple way to do this is to make a boolean variable in the class the says gotGun or whatever you want it to be. And if you confused right now don't worry i will explain it in a moment. And you shoot with keys im assuming so to start off with the code heres where it will begin. this is below the class signature. public static boolean gotGun "or whatever you will call it" = false; then you will put the code for when you pick it up below the act method public void pickUpGun() //"or whatever you want to call it" { Gun is whatever the name of the gun is Gun gun = (Gun) getOneIntersectingObject(Gun.class); if(gun != null) { gotGun = true; getWorld().removeObject(gun); } } so what this does is, when you touch the gun it will remove it and make it so that you will be able to shoot once you have put that boolean variable gotGun into action so the way you do that is simple so this is your player class lets say you use space to fire so here is the keyPress method public void checkKeyPress() { if (Greenfoot.isKeyDown("space") && Gun.gotGun == true) { then insert your fire method here } } then put the checkKeyPress and pickUpGun method into your actMethod
