How to apply HealthBar
The rest of this discussion deals with using my Progress bar/Health bar class.
Maybe that will help.
i already saw that but still can't figure out how to apply it
also some other scenarios as well but still can't figure it out
With my class, just include it, as is, into your project and follow my blueprint for the Zombie class in the discussion thread linked above.
if you got a picture for your actor like this:
image=new GreenfootImage("finish.png");
setImage(image);
you can simply add a text to it this way:
image.drawString("North",100,10);
100 and 10 are the coordinates and "North" a string, you add your health bar there i guess
Now i've got an error could you please check my code here it is
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
/**
* Write a description of class K here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class K extends ShooterActors
{
/**
* Act - do whatever the K wants to do. This method is called whenever
* the 'Act' or 'Run' button gets pressed in the environment.
*/
private int fspeed = 0;
private int acceleration = 2;
private int speed =5;
boolean CanJump;
KiBlast kiblast = new KiBlast();
private int points = 0;
private Bar healthBar;
public void act()
{
movement();
if(isOnGround()){
CanJump = true;
} else{
CanJump = false;
fall();
}
fire();
shoot();
}
public K()
{
healthBar = new Bar("", "", 100, 100);
healthBar.setShowTextualUnits(false);
healthBar.setBarWidth(30);
healthBar.setBarHeight(3);
}
public boolean isOnGround()
{
Cl Window = (Cl) getWorld();
if(getY() + (getImage().getHeight() / 2) >= (Window.getHeight() -1)) {
return true;
}
return false;
{ healthBar.setLocation(getX(), getY()-30);
if (healthBar.getValue() == 0) getWorld().removeObect(this); }
}
public void jump()
{
fspeed = -10;
fall();
}
public void fall()
{
setLocation ( getX(), getY() + fspeed);
fspeed = fspeed + acceleration;
}
public void movement()
{
if(Greenfoot.isKeyDown("left"))
{
MoveLeft();
}
if(Greenfoot.isKeyDown("right"))
{
MoveRight();
}
if(Greenfoot.isKeyDown("up"))
{
jump();
}
}
public void MoveLeft()
{
setLocation (getX() - speed, getY());
}
public void MoveRight()
{
setLocation (getX() + speed, getY());
}
public void fire()
{
if(Greenfoot.isKeyDown("x"))
{
World world = getWorld();
world.addObject(kiblast, 0, 0);
kiblast.setLocation(getX(),getY());
}
}
public void shoot()
{
{
if ("c".equals(Greenfoot.getKey()))
getWorld().addObject(new KiBlast(), getX(), getY());
points = points+5;
}
}
protected void addedToWorld(World world)
{
world.addObject(healthBar, getX(), getY()-30);
}
}
my error is on line 38
I fixed it but my only problem is that how will my hp be depleted when i get shot??
When the actor detects it has been hit and damage is done, use the 'subtract' method on the healthbar object to reduce its value.
how would my actor detect it? can i have the code for it?please
i understand what you mean but i can't apply it to my actor
Use one of the Actor class methods that are used for collision (intersection). Basically, if intersects damaging object, remove damaging object and decrement healthbar value; if healthbar value is zero, remove the actor.
how can i make the method of the bar available to my Main character actor also i'm going to use intersecting object for this right?
