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)

OK, That look s good! But theres just one thing, I would like it to wait like 2 seconds between each :Destroy() Would that be possible?

just add a wait(2) above it :).

Same place as before, I left it out accidently, just updated the answer for you again.

There is an Error at wait(2) Its expecting "Then"
0
missed that added it in. For clarification "any if condition should always be followed by a then keyword".

Hm So i have a tower of bricks and the one on the bottom name Bottom and on on top named top, it ALWAYS Delets the others but the bottom, so it seems like it not random :/
0
it's likely because bottom is rarely picked due to the fact that it's a random check between 0 and the total number of items in the model, if bottom is the first item (probably is) it's unlikely to get picked.

Hmm ok! Well Thanks :D O would upvote you but i need 1 REP :/
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.
