Sorry if I can't post this, first time posting here.

I'm new to Sims 2 modding. I want to make an object that is not autonomous for sims and have to made autonomously for sims to use. The object is the Runs with Scissors Playset by ADD. I know it's only use is for sims to run around and possibly get killed by it, but I'm playing the Asylum Challenge and I'd think it'd be interesting for sims to use it on their own. I've read tutorials on how to make objects autonomous for sims, but I'm not sure if I'm doing it right. Is there a way to do this? If so, how? Thanks!
