A CanCollide Command? [closed]

First, use string.sub() to get the substring of the msg that the player has chatted using the player event.

Get the player by using PlayerAdded. You must do this in a regular script. You can use Local scripts for this but the local script would get copied and there would have to be 1 local script per player instead of just 1 script for the whole server.

game:GetService("PlayerAdded"):connect(function(player)
    print(player.Name) --Get the player's name.
end)

See if they have chatted using the chatted event.

game:GetService("PlayerAdded"):connect(function(player)
    player.Chatted:connect(function(chat)
        if string.sub(chat, 1,8) == "/unlock " and workspace:FindFirstChild(string.sub(chat,9)) then
            workspace:FindFirstChild(string.sub(chat,9)).CanCollide = false
        elseif string.sub(chat, 1,5) == "/lock " and workspace:FindFirstChild(string.sub(chat,6)) then
            workspace:FindFirstChild(string.sub(chat,6)).CanCollide = true
        end
    end)
end)

Or you can do this to just lock the spawn.

game:GetService("PlayerAdded"):connect(function(player)
    player.Chatted:connect(function(chat)
        if string.sub(chat, 1,12) == "/unlockspawn" then
            workspace.Spawn.CanCollide = false
        elseif string.sub(chat, 1,5) == "/lockspawn" then
            workspace.Spawn.CanCollide = true
        end
    end)
end)

If you want to do this in a script:

function lock(part)
    part.CanCollide = true
end

function unlock(part)
    part.CanCollide = false
end

lock(game.Workspace.Part)
unlock(game.Workspace.Part2)

Hope it helps!

If you only want some people to say it:

admin = {"LordDragonZord", "Player1"} --Add your name here. Add as much people as you'd like.

game:GetService("PlayerAdded"):connect(function(player)
    player.Chatted:connect(function(chat)
        for _,AdminName in pairs(admin) do
            if player.Name == AdminName then
                if string.sub(chat, 1,8) == "/unlock " and workspace:FindFirstChild(string.sub(chat,9)) then
                    workspace:FindFirstChild(string.sub(chat,9)).CanCollide = false
                elseif string.sub(chat, 1,6) == "/lock " and workspace:FindFirstChild(string.sub(chat,7)) then
                    workspace:FindFirstChild(string.sub(chat,6)).CanCollide = true
                end
            end
        end
    end)
end)

Or...

admin = {"LordDragonZord", "Player1"} --Add your name here. Add as much people as you'd like.

game:GetService("PlayerAdded"):connect(function(player)
    player.Chatted:connect(function(chat)
        for _,AdminName in pairs(admin) do
            if player.Name == AdminName then
                if string.sub(chat, 1,12) == "/unlockspawn" then
                    workspace.Spawn.CanCollide = false
                elseif string.sub(chat, 1,5) == "/lockspawn" then
                    workspace.Spawn.CanCollide = true
                end
            end
        end
    end)
end)
