So I have a game https://scratch.mit.edu/projects/BuildingSim/ and when you hit the zoom in and out button its supposed to set the size of all the houses/shops/buildings to 50% and if your zoomed out have them all 30% but I can't figure out how to do this. Thanks hopefully you can help me! Also (forgot to say) there is a bug where you can place a building on top of another building that I tried to do but for some reason it won't work something to do with the script in sprite 2 and 3.

take out the

stamp

Then you can't place more than one house or store…

Then you either need to use

clear

and then redraw all the houses, which you could do if you save their co-ordinates in a list.
or
use clones…

In the house sprite, make a local variable “clone?” and put

set [clone? v] to [0]

in the first green flag script.

replace the second green flag with

when I start as a clone
show

and replace the stamp with

set [clone? v] to [1]
create clone of [myself v]
set [clone? v] to [0]
hide

In the clone script you suggested it just makes it even worse not letting you place houses anywhere or anything. And the stamp script and then clear and save coordinates I don't get…

If you use a grid system (you'll find a demo somewhere in my projects) all you need to do is record a number in a list which tells you what is at that grid position. Then very easy to redraw and to check whether the position is available. Both problems solved.

Edit - https://scratch.mit.edu/projects/47150778/

Zooming is then just a matter of costume sizes and adjusting the positions according to zoom level and, perhaps, the centre of zoom.

Sorry, I forgot one bit! You need the whole script under the “when i receive buildhouse” hat block to be inside

if <(clone?) = [0]> then

end

It still won't work for me???

just had a look at it, you've put it back to stamp but I can see the “clone?” variable you made is a global (for all sprites) and not a local (this sprite only) which is important!

I tried it again with local and it didn't work. I kept the script outside of the scripts I have so you can see what I did instead of stamp.

I made a remix https://scratch.mit.edu/projects/224905040/
