Why thank you kind sir! :)
Yes, but get Chair ID's how? Like, get new Chair's and add them into your WZ? Or dump a list of all Chair ID's in your current XML/WZ? For the first one, you can use something like WzRepacker that can copy nodes from the right-side to the left-side so you can obtain chairs without needing to do XML editing or anything else with a hassle. For the second one, you can use OdinMS's Maple Data Tools from the provider to parse the "0301.img" section of Ins.xml, loop the children, and output child.getName() which will be your chair ID. You can append it to a string or add it to a list or just directly output it to a log somewhere if you need it.
Hey, just curious. Do you by chance WZ Edit?
Because we all got busy with life/school. But also because v83 is a useless version to host. Top v83 right now according to GTOP is only #10.
