Which method of IF statements are better in terms of optimising and efficiency? [closed]

As of now, I've been using a mix of two:

method 1:

1local condition1 = true
2local condition2 = true
3local condition3= true
4 
5if condition1 and condition2 and condition3 then
6    print("all conditions are true")
7end

method 2:

01local condition1 = true
02local condition2 = true
03local condition3= true
04 
05if condition1 then
06    if condition2 then
07        if condition3 then
08            print("all conditions are true")
09        end
10    end
11end

Hi Marmalados,

According to Roblox Studio, method 2 is faster. I ran multiple tests to prove that and here is the code that I used:

Time Testing Code

01method1 = 0 -- Will count how many times method 1 came out to be successful in the trials.
02method2 = 0 -- WIll count how many times method 2 came out to be successful in the trials.
03 
04for x = 1, 100000 do -- Runs 100 thousand trials on the code.
05    t1 = tick()
06 
07    if workspace:FindFirstChild("Script") and workspace:FindFirstChild("Baseplate") then
08    end
09 
10    t1 = tick() - t1
11 
12    t2 = tick()
13 
14    if workspace:FindFirstChild("Script") then
15        if workspace:FindFirstChild("Baseplate") then
16        end
17    end
18 
19    t2 = tick() - t2
20 
21    if t1 < t2 then -- If method 1 turned out to be faster then add points to method 1.
22        method1 = method1 + 1
23    else
24        method2 = method2 + 1
25    end
26end
27 
28if method1 > method2 then -- If method 1 had more points then it is best.
29    print("Method 1 is best.")
30else -- Otherwise method 2 is better.
31    print("Method 2 is better.")
32end

I hope I helped and had a great day/night.

The first statement is like, if yes and yes2 and yes3 then runs the script, while method 2 is like if yes then (checkpoint) if yes2 then (checkpoint) if yes3 then (checkpoint) as in consequently checking if they are all accompanied to each other, as in if the first yes is true, then check if the 2nd yes is true, vise versa.

I believe if you want a more-effecient based script, i'd prefer method 2 as in consequently running check-ups while proceeding throughout the script. Like I said, the method 1 is just to check at first if all method's are true to proceed, while method 2 is checking if the first if statement is true, to proceed to second if statement and so on.

But which method would be less taxing on game performance? Marmalados 193 — 6y

Well, game performance really doesn't determine on a script's layout but I believe what you're wondering is what's the best way to not request to much information from the game, which you're not really requesting much here unless you're planning to use RemoteEvents, as in I would say method 1 would be best for that, as it runs it through the first line. The method 2 would just check continuously. Resplendid 3 — 6y
