How do I make background shake?

nlin060

I want to make an Earthquake-feel. But I don't know how to make the background shake, if that even is possible?
All help is much appreciated, thank you so much in advance!

You could try using a sprite for the background, zoom it in a little and then code it to shake and move.

Good question!
I hope my answer is just as good too!
Maybe, instead of using a backdrop, use a sprite instead. I've seen people do this before so I know it works, by the way. Use the sprite and click on “Movement.” Then, you can make it glide back and forth or rotate it. I dunno if that'll suit your project… but it's another idea! Really good question!

If you'd like, check out my featured project on my profile. It would mean SO MUCH to me if you did.

If you mean screen shaking like in Ace Attorney, then do the following:
1. Make your backdrop entirely black
2. Create a sprite for the background and bring it back every layer
3. Use the following script:

define shake (initial intensity) (falloff)
set rotation style [don't rotate v]
set [force v] to (initial intensity)
play sound [boom v]//optional
repeat until <not <(force) > [0]>>
go to x: (0) y: (0)
point in direction (pick random (0) to (359))
move (force) steps
change [force v] by ((-1) * (falloff))
end
go to x: (0) y: (0)

note: setting (falloff) to anything other than a positive number will cause the shaking to be infinite

Do it as a sprite:

when green flag clicked
go back (10) layers
forever
change y by (-10)
wait (.05) secs
change y by (10)
end

Really cool question!
I've actually done something like that before just recently. Some say a sprite would be easier, but I wouldn't go that direction, especially if you need to click and drag lots of other sprites around it. Just make one backdrop and duplicate it to go left sometimes and right some others. https://scratch.mit.edu/projects/160229686/ . This demonstrates ways you can make the background move with the actual backdrops.

That's a bit of a waste. It just creates clutter and gives people with slower computer substantially more lag.

it cannot shake! only sprites can shake!

Use the select tool to select the entire backdrop and paste it into a sprite. Then do this:

when green flag clicked
show
set [Intencity v] to [5]
switch costume to [shakeyshakey v] 
go to x: (0) y: (0)
repeat (idc)
change y by (Intencity)
change y by ((Intencity) * (-1))
end

repeat ()
change x by ((pick random (-3) to (3)) * (5))
change y by ((pick random (-3) to (3)) * (5))
wait () secs
end

Please do not spam or necropost. Thanks.

Catsarefun

when green flag clicked

I don't think you can change backgrounds(even a code expert can't help me)!

You literally just do:

switch backdrop to [ Another backdrop v]

Edit: BTW that was kinda off topic and I think this is already resolved…

Another edit: This was from 2017 soo it was definitely resolved… Please don't necropost.
