Can You be a little more Precise? Just move forward and back? Randomly? If yes, in which delay? You can post code here by inserting it between Code and /Code

*Here's the actor i that i want to move back and forward* import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) /** * Write a description of class Alligator here. * * @author (your name) * @version (a version number or a date) */ public class Alligator extends Actor { /** * Act - do whatever the Alligator wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { // Add your action code here. } } could you add the code for it to do that, also once it make connection with one of the actors called goldenball the goldenball will disappear

Well I'll just pretend u want it to walk forward and back in a certain duration? Use a random number, which you have to figure out for yourself since I don't know how long you want it to move Whenever your number is 0 Turn 180 degrees

Private void walk()
{
   Int pause = x  //<- Pick a number
   Move(y);        // y= move speed
   If(pause>o)
{
   pause--;
}
   else
{
    setRotation(getRotation-180)
    pause = x
}
}

private void touch
{
    Actor a = getOneIntersectingObject(goldenball.class)
    If( a != null)
{
    removeObject(a)
}
}

afaik there is nothing as "steps", they move pixel by pixel Just try around some numbers for x, to get the desired distance
