Bro, thank you so much! You don't know how much I needed this! *Hugs*

Wait your script isn't working for me, could you get the script to be identical and have NO variable in the size, just poststep? Just try and edit this code to have the same effect (e)=>{
((keys.isdown("[4]") || keys.isdown("left")) && size(1) < 0.15507431) ? {
size = [0.40625, size(1) + 0.003]
} : {};
((keys.isdown("[1]") || keys.isdown("right")) && size(1) > 0.011029838) ? {
size = [0.40625, size(1) - 0.003]
} : {}
}

Did ya copy-paste the exact box? You can't move the script to another box bcause the local vars won't come with it!

Anyways I can't really help with that script....

Well I really don't want to directly copy the box entirely, maybe try and re-do the script that doesn't need any local vars, like mine? Because I've been trying and this script doesn't work at all for me, and I don't like to directly copy+paste the box to my engines.

What's wrong with copy-pasting? I mean, you could change color, density, size, etc?

I just never liked it.. it makes me feel like I'm just stealing something from someone else's scene, plus if it is a script on it's own, it's easier to adjust and stuff
