Button Fire / Button shoot
Okay. A best place to put the code is in the buttonshoot (tambak) class. Remove all previous codes that try to shoot and change the act method in the tambak class to:
public void act()
{
if (Greenfoot.mousePressed(this))
{
addObject(new Bullet(), getX(), getY());
}
}this code i try. but position not in roket but the bullet position in buttonshoot. i want if i press the button shoot, then the bullet position in roket. this game popular shoot. have the button for shoot and navigation. please help me mr. :)
Adjust class names as needed:
//in Player class
private Actor shootButton = new Button();
protected void addedToWorld(World w)
{
w.addObject(shootButton, x-coordinate, y-coordinate); //use x and y of the position where the button should be
}
public void act()
{
if (Greenfoot.mousePressed(shootButton))
{
addObject(new Bullet(), getX(), getY());
}
}if i put this code in class roket, this not work. but it i'm change this to if (Greenfoot.mousePressed(this)), this work but i must press the rocket not button shoot :(
i want press the button shoot and rocket fire the bullet.
Logic its same of the code. but not work :(
Do you only add the button from the rocket class and not from the world?
i add button shoot in world. addObject(new buttonshoot(), 200, 300);
and no problem.
i add one more object, this is roket object.
i put the your code in class roket, but not work. i'am sory, please me :)
Try this in the bulletsoot class:
public void act()
{
if (Greenfoot.mousePressed(this) && !getWorld().getObjects(Rocket.class).isEmpty())
{
Actor rocket = (Actor)getWorld().getObjects(Rocket.class).get(0);
addObject(new Bullet(), rocket.getX(), rocket.getY());
}
}Ok, so you control the rocket from your world class. Why are you not doing the same thing for the shooting?
uh i'm sory mr.super_hipo .. i want the all control have one button. i post my problem. can you see that? please me :) i'am very new in greenfoot
I did see it. That's why I asked you why the shooting button isn't a button like the moving buttons. Those buttons change a variable in the world which then controls the rocket based on those variables. (This is not the best way of doing it, but it is a way at least.)
The shooting button could do a similar thing, change a variable in the world which lets the rocket shoot its bullet.
so i must make the method for the roket can shoot and that method i must make in world? ...
oke i want try. thank mr :) but if you have time, you can help me solved that project, please me mr.:)
]In Latar class, change 'new tembak()' to 'new tembak(roket)'. Then have this for tembak class:
and for the roket class:
import greenfoot.*;
public class tembak extends Actor
{
private roket roket;
public tembak(roket roket)
{
this.roket = roket;
}
public void act()
{
if (Greenfoot.mousePressed(this))
{
getWorld().addObject(new peluru(), roket.getX(), roket.getY());
}
}
}import greenfoot.*;
public class roket extends Actor
