How would i take the getX() of one object and apply it to another object? Also how would i add an object to the world after a condition has been met?

if (condition) getWorld().addObject(new ObjName(), getX(), getY());

public void checkTarget()
    {
        if(Greenfoot.isKeyDown("z"))
        {
          getWorld().addObject (new laser(),300, 165);
        }
hmm. This was my code but when i try to run it nothing occurs. And where the 300 is i want to set that equal to an object that is already in the world. Do i need to set the other objects x = to a variable then out that where 300 is?

(1) make sure you can instantiate a laser object by right-clicking and selecting 'new laser()' from the options and then clicking anywhere in the world area (2) make sure that the 'checkTarget' method is being called somewhere within the 'act' method or a method it calls (3) you will probably need to add a delay between laser bursts

Does this mean: step 1: passed step 2: passed but, still no laser objects appear during the running of the simulation while the z key is pressed?

Ok. Post the class that 'fires' the laser.

The act method of an object is only called if it is in the world. Maybe thats the problem. Are you shure that the object that calls the method is in the world when you press the key?

Make sure your 'Caps Lock' is off.

ah i think i might not have explained myself clearly. Im not shooting lasers. Im trying to make a sort of "orbital cannon" i want the player to be able to move the "target" to the location they want and i want the laser to take the X coordinate of the target and use it as its own. i dont have a fireLaser() class

In what class did you place this code? Is it a world class or an actor class? and what is the name of that class?
