I have a boss actor and I only want it to move a certain amount. I've looked everywhere but nothing I find nothing that helps here is the code: /** * Write a description of class WalkerBoss here. * * @author (your name) * @version (a version number or a date) */ public class WalkerBoss extends Actor { private int frame; private GreenfootImage walker1 = new GreenfootImage("WalkerBoss1.png"); private GreenfootImage walker2 = new GreenfootImage("WalkerBoss2.png"); private GreenfootImage walker3 = new GreenfootImage("WalkerBoss3.png"); private GreenfootImage walker4 = new GreenfootImage("WalkerBoss4.png"); private GreenfootImage walker5 = new GreenfootImage("WalkerBoss5.png"); private GreenfootImage walker6 = new GreenfootImage("Walkerboss6.png"); private GreenfootImage walker7 = new GreenfootImage("WalkerBoss7.png"); private GreenfootImage walker8 = new GreenfootImage("WalkerBoss8.png"); private GreenfootImage walker9 = new GreenfootImage("WalkerBoss9.png"); private GreenfootImage walker10 = new GreenfootImage("WalkerBoss10.png"); private GreenfootImage walker11 = new GreenfootImage("WalkerBoss11.png"); private GreenfootImage walker12 = new GreenfootImage("WalkerBoss12.png"); private GreenfootImage walker13 = new GreenfootImage("WalkerBoss13.png"); private GreenfootImage walker14 = new GreenfootImage("WalkerBoss14.png"); private GreenfootImage walker15 = new GreenfootImage("WalkerBoss15.png"); private GreenfootImage walker16 = new GreenfootImage("Walkerboss16.png"); private int imageCounter; private int walkerspeed = -8; private int speed = 0; public static GreenfootSound AT_AT_Walk = new GreenfootSound("AT AT sound.mp3"); int collisionCountdown = 0; private int timer = 0; public void act() { bossmove(); AT_AT_Walk.playLoop(); } private void addTimer(){ timer++; } public void bossmove() { imageCounter = (++imageCounter)%15; // change '2' higher to slow down animation if (imageCounter == 0) switchImage(); } public void move() { bossmove(); } public void switchImage() { move(walkerspeed); frame++; switch (frame){ case 1: setImage(walker1); break; case 2: setImage(walker2); break; case 3: setImage(walker3); break; case 4: setImage(walker4); break; case 5: setImage(walker5); break; case 6: setImage(walker6); break; case 7: setImage(walker7); break; case 8: setImage(walker8); break; case 9: setImage(walker9); break; case 10: setImage(walker10); break; case 11: setImage(walker11); break; case 12: setImage(walker12); break; case 13: setImage(walker13); break; case 14: setImage(walker14); break; case 15: setImage(walker15); break; case 16: setImage(walker16); break; case 17: frame = 0; } } private void checkForJump() { } /** * Hit this asteroid dealing the given amount of damage. */ public void hit(int damage) { } }

public void move()
{
    move(5)
}
That's a simple method for an object to move... Which then you can get much more complex with it. In regards to what direction, or if you want it to move toward when a key is pressed. Sorry for errors, on my phone.

Use something like: 
if (getX() > 300) move(walkerspeed); // addjust location as needed
for the first line of the switchImage method.

Ok, I have one problem with that and that is the switch image method doesn't stop with the movement. How would I fix this?

One way is to change it to: 
if (getX() < 300) return;
move(walkerspeed);

Ok, that worked but there is one more thing I can't seem to get, the walking sound effect also doesn't stop with it any way I could get that to stop?

Add a third line to the above: 
if (getX() < 300) AT_AT_Walk.stop();

Ok, I did that, but it stops and then starts to play again. It doesn't stop completely

That is because you start it in your act method. Start it in a constructor block instead.

I did that the only thing that it did was that it stopped longer than played again. Maybe im doing it wrong?

public void WalkerEffect() { AT_AT_Walk.play(); } That is the code I added.

Remove the word void to make it a constructor and not a regular method. Also, it should be called WalkerBoss (using the name of the class).

Alright. Time to go back a bit. Remove the constructor and start the sound in the act method using this line: 
if (AT_AT_Walk != null) AT_AT_Walk.playLoop();
Then do the following: 
// change this line
if (getX() < 300) AT_AT_Walk.stop();

// to this
if (getX() < 300)
{
    AT_AT_Walk.stop();
    AT_AT_Walk = null;
}
