How do I make a script that will delete all children in a model except for one!? [closed]

function destroyAllBut(model, keep)
    for k, v in next, model:GetChildren() do
        if v.Name ~= keep then
            wait(2)
            v:Destroy()
        end
    end
end

destroyAllBut(game.Workspace.Model, "Banana");

First things first, the part or object you want to keep will have a unique name, assuming so anyway, so pass that as the second argument to the function.

The first argument is the path to your model.

:Destroy() will destroy any thing and it's children that doesn't share the name of the object you want to keep.

This will destroy everything in the model except objects that have the same name as the keep argument, as a result it is more useful than just keep all but one object.

If you do just want to keep any random one object use this.

function destroyAllButOne(model)
    num = #model:GetChildren()
    for k, v in next, model:GetChildren() do
        if k < (num - 1) then
            wait(2)
            v:Destroy()
        end
    end
end

destroyAllButOne(game.Worskpace.Model)

Destroy all but Random

function destroyAllButRandom(model)
    math.randomseed(tick())
    local random = model:GetChildren()[math.random(0, #model:GetChildren())]
    for k, v in next, model:GetChildren() do
        if v ~= random then
            wait(2)
            v:Destroy()
        end
    end
end

destroyAllButRandom(game.Workspace.Model)

This script will destroy every child of a model except one. Make sure to point the mdl variable to the model you would like the script to use.

This removes every part of the model except one random one:

mdl = game.Workspace.Model
items = mdl:GetChildren()

for i = 1, #items - 1 do
    wait(2)
    items[i]:Destroy()
end

This removes every part of the model except one you want to keep:

mdl = game.Workspace.Model
keep = "Special"
items = mdl:GetChildren()

for i = 1, #items do
    wait(2)
    if(items[i].Name ~= keep) then
        items[i]:Destroy()
    end
end

Well, You can get children. I'm sure alot of people wont use my method but here's some code:

model = game.Workspace.model -- What model?
children = model:GetChildren() -- Get an array.
dontremove = "bob" -- Name of the object that we wont remove
for i = 1, #children do
    if children[i].Name ~= dontremove then --If the child's name isn't bob.
        children[i]:Remove() -- Remove it.
    end
end

Here's a reference for the future: http://wiki.roblox.com/index.php?title=GetChildren_(Method)

In the script below, you can place multiple names in the 'Keepers' table, objects found inside the 'Instance' variable (obj) with a name that is found inside the table will not be deleted.

function tableFind(table, val)
    for _, v in pairs(t) do
        if v == value then 
            return true
        end
    end
    return false
end

Keepers = {
    'Part';
    'OtherPart'; -- Optional
}
Instance = Parent['ModelName']
for _,v in pairs(Instance:GetChildren()) do
    if not tableFind(Keepers, v.Name) then
        v:Destroy()
    end
end

Hope this helps.
