Hi, I'm trying to code a small game for a school project, but I'm sort of stuck.
I want the game to be about a character dodging vines coming from the ceiling, and everything works except for the last part of the vines. What I'm trying to achieve is that the vines will come down from the ceiling, go back up and disappear, sp that another vine can come down to do the same thing over and over.
But the vines either won't disappear. or give me an error about the line of code that kills my character when it touches a vine not working anymore.
Does anyone know how I could fix this?
here is my code by the way:
class code:
world code:
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class Vine1 here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class Vine1 extends Actor
{
GifImage myGif = new GifImage("maybe this works.gif");
/**
* Act - do whatever the Vine1 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.
setImage( myGif.getCurrentImage() );
runVineDownTimer();
Actor tommy;
tommy = getOneObjectAtOffset(50,150, Tommy.class);
if (tommy != null)
{
World world;
world = getWorld();
world.removeObject(tommy);
}
//if (Greenfoot.getRandomNumber(100) < 10)
//{
//if(Greenfoot.isKeyDown("right")) setLocation(getX()+3, getY());
//if(Greenfoot.isKeyDown("left")) setLocation(getX()-3, getY());
//if(Greenfoot.isKeyDown("down")) setLocation(getX(), getY()+3);
//if(Greenfoot.isKeyDown("up")) setLocation(getX(), getY()-3);
//moveDown();
//}
}
private int VineDownTimer;
private void runVineDownTimer()
{
VineDownTimer = (VineDownTimer+1)%300;
if (VineDownTimer < 200) moveUp();
if (VineDownTimer > 200) moveDown();
if (VineDownTimer == 0) getWorld().removeObject(this);
}
public void moveDown()
{
setLocation(getX(), getY()+2);
}
private void moveUp()
{
setLocation(getX(), getY()-6);
}
}import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class MyWorld here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class MyWorld extends World
{
/**
* Constructor for objects of class MyWorld.
*
*/
public MyWorld()
{
// Create a new world with 600x400 cells with a cell size of 1x1 pixels.
super(400, 400, 1);
prepare();
}
public void act()
{
setPaintOrder(Tommy.class,Vine1.class);
// in act method of world class
runVineSpawnTimer();
}
// instance field in world class
private int VineSpawnTimer;
// new method in world class
private void runVineSpawnTimer()
{
VineSpawnTimer = (VineSpawnTimer+1)%300; // adjust '300' as desired
if (VineSpawnTimer == 0) spawnVine();
}
//e
private void spawnVine()
{
// add code spawning vine here
int x = Greenfoot.getRandomNumber(400);
addObject(new Vine1(), x, -50);
}
/**
* Prepare the world for the start of the program.
* That is: create the initial objects and add them to the world.
*/
private void prepare()
{
Tommy tommy = new Tommy();
addObject(tommy,190,350);
}
