Magazine to gun.
You can try adding a variable to represent the amount of magazines the gun has left. Otherwise, please specify your scenario XD
I need it to this game: http://www.greenfoot.org/scenarios/8390
Once again, it is simple. Have a variable called Ammo in your player class. Every time you fire, presumably by clicking the left mouse button, decrease this variable. Then, when Ammo = 0, have a delay before you reset Ammo to 8, for example, and then you can fire again. In the if statement controlling when you fire, add the condition that Ammo has to be greater than 0.
int Ammo = 10;
int reloadDelay = 100;
if (Greenfoot.isKeyDown("space") && Ammo > 0)
{
Code to fire a bullet
Ammo--;
}
if (Ammo <= 0)
{
reloadDelay--;
if (reloadDelay <= 0)
{
Ammo = 10;
reloadDelay = 100;
}
}
This doesen't act:
import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)
public class Soldier extends Actor
{
private int soldierSpeed = 3;
private GreenfootImage soldierWalk1 = new GreenfootImage("Roboani1.png");
private GreenfootImage soldierWalk2 = new GreenfootImage("Roboani2.png");
private GreenfootImage soldierWalk3 = new GreenfootImage("Roboani3.png");
private int animationCount = 0;
private int frame = 1;
private int mouseX;
private int mouseY;
public static int currentX;
public static int currentY;
public static int currentRot;
int Ammo = 10;
int reloadDelay = 100;
public void act()
{
move();
faceMouse();
shoot();
currentX = getX();
currentY = getY();
currentRot = getRotation();
}
public void move()
{
animationCount ++;
if(Greenfoot.isKeyDown("w"))
{
move(3);
if(animationCount % 8 == 0)
{
animationWalk();
}
}
else if(Greenfoot.isKeyDown("s"))
{
move(-3);
if(animationCount % 8 == 0)
{
animationWalk();
}
}
else
{
setImage(soldierWalk1);
}
}
public void animationWalk()
{
if(frame == 1)
{
setImage(soldierWalk1);
frame = 2;
}
else if(frame == 2)
{
setImage(soldierWalk2);
frame = 3;
}
else if(frame == 3)
{
setImage(soldierWalk3);
frame = 1;
}
}
public void faceMouse()
{
if(Greenfoot.getMouseInfo() != null)
{
mouseX = Greenfoot.getMouseInfo().getX();
mouseY = Greenfoot.getMouseInfo().getY();
turnTowards (mouseX, mouseY);
}
}
public void shoot()
{
if (Greenfoot.isKeyDown("space") && Ammo > 0)
{
if(Greenfoot.getMouseInfo() != null)
{
if(Greenfoot.getMouseInfo().getButton() == 1)
{
getWorld().addObject(new Bullet(), getX(), getY());
Ammo--;
}
if (Ammo <= 0)
{
reloadDelay--;
if (reloadDelay <= 0)
{
Ammo = 10;
reloadDelay = 100;
}
}
}
}
}
