so i have a 3 level game that has to change the background for each level, and i have a background actor to do this. the problem is that when i start the second level, the background image is still initially the first one and it takes a quick second for it to change to the second one. i would like to know if there's a way to have it set to the second picture by the time the second level starts.

You will need to show your codes for review.

I have thisin my background actor:

public static GreenfootImage picture; 
    public void act() 
    {
        setImage(picture);
}

this in level1's act:

background.picture = new GreenfootImage ("background1.png");

and this in level2's act:

background.picture = new GreenfootImage ("background2.png");

initially the background is set to "background1.png"; after level1 is over, level2 starts, and it changes the picture, but for the first frame it still shows the first image...

You should just set the image when the level changes instead of changing the field value (background.picture). The you would not need the field or setting the image every act cycle.

Show code changing worlds.

You could just use multiple worlds instead of actors for that. If you complete a level, let's say you have to touch a specific object, set a condition e.g.

if (isTouching(object.class))
{
    Greenfoot.setWorld(new Level2());
}

Each world has a different Background

\i do have different worlds, but the background is moving, that's why i'm using an actor

this reminded me that i should change the picture when setting the new world, not once it's set. thank you.
