Hi!
I'm planning to make a lot that's like a run down/closed down fair/arcade/amusement park, but I would like stuff like the popcorn machine/slush maker etc (they were store content items, right?) to be like, decorative only/preferably empty as well. Does anyone know where the best place is to find that stuff? I'm sure someone else must have had the same thought at some point, lol.

I was also hoping that booths/stalls (like the snack booths from Seasons) would be somewhere as deco items as well? Or maybe they are possible to "shut down" with a nraas mod? I believe one of the nraas mod could make items unsuable in some way but I forget how, or if it would work on something that needs an NPC.

Nraas' Register will let you select a role giving object and disable NPC assignment (I use this a lot to keep the LN bars from bringing in people to play piano). The popcorn machine is from the store but the slushie machine is from Seasons. To keep people from using it, you could try the Trasmogrifier to change their script to a decorative item. Please note that the popcorn machine has an associated sound of popping that constantly plays (even if it's on a festival lot for a different season).

Mod the Sims has a lot of the Sims 4 stalls converted but unfortunately they aren't recolorable so you can't make them look worn down.

First, thank you, omg I've been thinking forever about keeping sims from playing instruments on lots, lol! XD
Secondly, thanks again, I've got the Nraas Register, so. I guess the Nraas Register thing will work to keep NPCs/randoms from using those the popcorn/slushie too? It would be a closed off lot anyway so I'm not too bothered by that, I was hoping that I could find it somewhere without popcorn/looking empty.

Thank you for the links, I'll have a look around and see if maybe I have skip those two items and maybe find something else or think differently. :-)
