How to use GetChildren() to weld a bunch of parts together at once?
The model I am making is a drawer with a bunch of cups inside of it. I inserted a Script into the part of the model that the cups are attaching to so I could weld them together. However, since the cups are all the same and there is a lot of them, I don't want to weld them individually, so I tried to weld them all at once:
01 | drawers = script.Parent |
02 |
03 | cups = drawers.Parent.Cups:GetChildren() |
04 | for _, child in ipairs(cups) do |
05 | CupWeld = Instance.new("Weld") |
06 | CupWeld.Parent = child |
07 | CupWeld.Part0 = child |
08 | CupWeld.Part1 = drawers |
09 | CupWeld.C0 = CFrame.new(child.Position.x,child.Position.y,child.Position.z)-Vector3.new(drawers.Position.X,drawers.Position.Y,drawers.Position.Z) |
10 | end |
This works, sort of. The cups DO weld to the drawers, but they are all in one place. I want them to be in the position they were in before the script is run.

If you are welding them all to to one part then you need to get the offset of each cup from that part. The CFrame math is weird but all you need to know is that the offset of a cf1 from cf2 is cf1:inverse() * cf2. Also achieved by a simple cf1:toObjectSpace(cf2). This is easy to work in.
You also have to make sure you give the weld a parent at the last step, or else the cups teleport before you set C0.
01 | drawers = script.Parent |
02 |
03 | cups = drawers.Parent.Cups:GetChildren() |
04 | for _, child in ipairs(cups) do |
05 | CupWeld = Instance.new("Weld") |
06 | CupWeld.Part0 = child |
07 | CupWeld.Part1 = drawers |
08 | CupWeld.C0 = child.CFrame:toObjectSpace(drawers.CFrame) |
09 | CupWeld.Parent = child |
10 | end |
Cheers!
