How to choose a random number?
No- I'm not really asking for something that basic.
Basically, what I'm trying to do is when the player clicks the button, it determines a random number (currently between 1 and 4, though I want to add more) and if the number is 1, it teleports them one place, if its 2 then it teleports them to another place, and so on.
01 | local i = math.random(4) |
02 | if 1 then |
03 | game.Players.LocalPlayer.Character.Torso.CFrame = CFrame.new(154.8, 5, -167.8) |
04 | end |
05 | if 2 then |
06 | game.Players.LocalPlayer.Character.Torso.CFrame = CFrame.new(-37, 5, 0) |
07 | end |
08 | if 3 then |
09 | game.Players.LocalPlayer.Character.Torso.CFrame = CFrame.new(197, 5, 154) |
10 | end |
11 | if 4 then |
12 | game.Players.LocalPlayer.Character.Torso.CFrame = CFrame.new(-99, 5, -217) |
13 | end |
14 | wait(1) |
15 | end |
What (i think) the problem is is that the game reads that i = 4 instead of whatever random number it is, but I dont know how to fix it... it always teleports me to option 4
Help please :o

Your Problem
You're not comparing the random number, i, to the specified number! You're just stating if [number] then when you need to state if i == [number] then.
01 | local i = math.random(4) |
02 |
03 | if i == 1 then |
04 | game.Players.LocalPlayer.Character.Torso.CFrame = CFrame.new(154.8, 5, -167.8) |
05 | end |
06 | if 2 then |
07 | game.Players.LocalPlayer.Character.Torso.CFrame = CFrame.new(-37, 5, 0) |
08 | end |
09 | if 3 then |
10 | game.Players.LocalPlayer.Character.Torso.CFrame = CFrame.new(197, 5, 154) |
11 | end |
12 | if 4 then |
13 | game.Players.LocalPlayer.Character.Torso.CFrame = CFrame.new(-99, 5, -217) |
14 | end |
15 | wait(1) |
16 | end |
Efficiency Fixes
Current Code Setup;
You should use
elseifstatements after your initialif statement.You should make a variable, so you don't have to repetitively type
game.Players.LocalPlayer.Character.Torso.
New Setup;
But I mostly suggest making a table full of all of the wanted CFrames. This way, you can index the table with the random number..
Indexing a table works like this;
1 | local a = {3,2,1} |
2 | local b = a[1] |
3 | print(b) -->3 |
'b' printed '3' because index 1 of table 'a' was 3. So if you index the table randomely then it will get a random index..
Another thing you should know is that the # operator gets the length of any string or table, so if you use math.random with the second argument of #[table], '[table]' being whatever table you're getting the index of, then it will automatically adjust to th table's size.
Goulified Code
01 | --Table of positions |
02 | local Positions = { |
03 | CFrame.new(154.8, 5, -167.8), |
04 | CFrame.new(-37, 5, 0), |
05 | CFrame.new(197, 5, 154), |
06 | CFrame.new(-99, 5, -217) |
07 | } |
08 |
09 | --Random index number |
10 | local i = math.random(1,#Positions) |
11 | --Random Position, from 'Positions' table. |
12 | local pos = Positions[i] |
13 | --Character Variable |
14 | local char = game.Players.LocalPlayer.Character.Torso |
15 |
16 | --Teleport character |
17 | char.CFrame = pos |
0
Wouldn't you need to say if i == number instead of just if number?
