hello!!! so i'm planning to set a background, but the moment i press run, it changes. does anyone know how to do this? thank you so muchUm because i am making a game, so before making the program run, i want to have a background that says "press run to play"
once run is pressed however, the background will change into a new one which is the background that is set when the game is played
i hope this is clear enough :(
Make use of the 'started' method:
You did not show your code here -- but remove any other places where you try to set that particular image.
public void started()
{
setBackground(<< new background filename >>);
}
public class bg extends World
{
//GreenfootSound backgroundMusic = new GreenfootSound("music.mp3");
public void started()
{
setBackground("start.png");
GreenfootImage bg = new GreenfootImage("start.png");
bg.scale(getWidth(), getHeight());
}
public bg()
{//this sets the background
super(600, 400, 1);
setBackground("Final ICT BG.png");
//backgroundMusic.playLoop();
GreenfootImage bg = new GreenfootImage("Final ICT BG.png");
bg.scale(getWidth() +35, getHeight() +30);
setBackground(bg);
prepare();
//if("enter".equals(Greenfoot.getKey()));
}I think this is what you want:
public class bg extends World
{
public bg()
{
super(600, 400, 1);
GreenfootImage bg = new GreenfootImage("Final ICT BG.png");
bg.scale(600, 400);
setBackground(bg);
prepare();
}
public void started()
{
GreenfootImage bg = new GreenfootImage("start.png");
bg.scale(600, 400);
setBackground(bg);
}
//...
Remove line 7 and change the 'bg' in line 8 to 'getBackground()'. As it is right now, 'bg' is a new image and you scale it, but it is not the same image as the one you set as the background in line 6.
Same goes for line 13 vs. line 16. Since you use line 18 there, this 'bg' is used as the background, you can remove line 13 or do the same as described above.
Thank you so much, to the both of you! it's working! i'm sorry i've been asking so much questions for the past days
don't be sorry the forum is here for a reason
