The equals method compares the characters/content in the string (true if they are the same), == is only true if they are both the same string (the same object). As a simple rule: Always use equals instead of == for strings. (Unless you actually want to check if it is the same object of course.)

You cannot call a method (showText -- on last line) on a non-existent object. The reference to a World object returned by getWorld will be null if this actor is removed from the world (previous line). Change last line to: <Code Omitted>

thx dadpost

epico its working now :)

So i am using shift instead of q and now everything is working fine. Thank You.

Please provide code, error and location of error.

If the orc is an intersecting object, then line 7 removes the wrong actor.

nvm figured it out

If you have a variable in your Enemy class which saves the traveled distance for the actor (increase it by its speed whenever it moves) and a method to return it … <Code Omitted>… then a tower can get the enemy in range with highest distance traveled and shoot a bullet in that direction:

Have the method, addMarbles, and add all the marbles in one calling. That is, move the loop from the constructor to the method. That way, the loop counter value can aid in controlling the y-coordinate value where the marbles are placed.

<Code Omitted>

it would probably just be easier to add the new drone in the previous drone like this<Code Omitted>

import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) /** * Write a description of class Vcela here. * * @author (your name) * @version (a version number or a date) */ public class Vcela extends Actor { /** * Act - do whatever the Vcela wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { if (Greenfoot.mouseClicked(this)) { ((Louka) getWorld()).smazVcely(); } } }

Thank you very much

Works, thank you very much! :)
