Hi
I'm trying to make the background flash between two back grounds while a sprite provides information in front of the flashing back ground. Up to now I have just alternated the back grounds between when the sprite say something but the code looks really confusing and messy. Does anyone have any ideas how I could do this? I tried to setup a broadcast to a repeat the back ground change 10 times in a loop and then continue with the main part of the program but that doesn't seem to be working.

I hope this makes sense.

If anyone who would like to play the game so they can see what I mean that would be great.

Thanks in advance

Would this do it? Or am I not understanding?

forever
    
switch backdrop to [next backdrop v]
end

Part of my problem is that for the evaporation question I need the backdrops to alternate between the normal backdrop and the evaporation backdrop. On the condensation question I need the backdrops to alternate between the normal backdrop and the condensation backdrop. Maybe I didn't create the game that well but the game evolved into what it is and it got more complicated than what I originally thought it would. At first I just wanted something to teach my son and then I saw all the cool things I could teach him and well……here I am.

Anyway, because I need specific backdrops to alternate depending on the “water cycle question” question I don't think your suggestion will work. Perhaps I'm wrong?

Thanks for your reply

Try something like this:

when I receive [evaporation flash v]
repeat (10)
switch backdrop to [Evaporation v]
wait (0.2) secs
switch backdrop to [Normal day v]
wait (0.2) secs
end

Thanks for your response. That worked. When I tried that without the wait time periods in between the switch backdrops it didn't work. I'm not sure why? Anyway thanks so much for your help.

Without the wait blocks between the switch backdrop blocks, the backdrop will switch very quickly, making it look like it never changed at all.

Ok that makes sense. Thanks for explaining that.
