This article provides a method for switching between backdrops.
First, create a variable called screen:
This variable will store which backdrop is shown.
Then, in every sprite that would transition, put this:
when green flag clicked ... //Code before loop forever if <(screen) = [backdrop]> then //checks if the screen variable is the same as the wanted screen for the sprites to be shown show //If true, sprite is shown ... //Code for when it is shown else hide //If not true, sprite is hidden ... //Code for when it is hidden. end end
In short, the script checks whether the screen variable is the same as the screen for showing the sprites. If so, the sprites will show and do whatever is required. If not, it will stay hidden and run the blocks for when it is hidden.
For the stage, put this:
when green flag clicked ... //whatever code is wanted before loop forever switch backdrop to (screen) //Switches the backdrop to the string stored in the variable end
This script constantly switches the backdrop to the string stored in the variable
If music should change based on the screen, add the following script to the Stage (or the sprite playing the music if a sprite is playing the music):
when I receive [change music v] stop all sounds // this method could also be used to stop the music if <(screen) = [screen 1]> then forever // so the music doesn't randomly stop play sound [music 1 v] until done end end if <(screen) = [screen 2]> then forever play sound [music 2 v] until done end end ...
Execute this broadcast every time the music needs to be changed.
To make a black screen, first create a variable called
(next screen). Then, insert this into the black screen sprite:
when I receive [black screen v] go to front set [ghost v] effect to (100) // invisible show repeat (20) change [ghost v] effect by (-5) // fade into view end set [screen v] to  // nothing broadcast [change music v] // stop the music wait (1) secs set [screen v] to (next screen) // the screen to switch to broadcast [change music v] // change the music to the screen repeat (20) change [ghost v] effect by (5) // fade out of view end hide
Use this to execute the black screen:
set [next screen v] to [wanted] broadcast [black screen v]
