i’m wondering when you would use the for loop
for i = 1, 10, 3 in pairs
-- code
end
i understand 1 is the beginning, 10 is the end, and 3 is the increment but when would someone use this type of for loop?
i only know how i would use
for i, v in pairs()
-- code
end
Here are 5 examples I usually use these for:
local arr = {1,4, "string"}
for i = 1,#arr,1 do
print(arr[i] .. "is number" .. i)
end
for i = 10,0,-1 do
print(i .. " seconds left!")
wait(1)
end
local str = "Hello this is my string"
local loopStr = ""
for i = 1, #str,1 do
loopStr = loopStr .. str:sub(i,i)
print(loopStr)
end
for i = 1,10,1 do
print("I want this to repeat 10 times")
end
Apparently, looping with the increment is faster than the in-pairs or next.
Lets say I had these parts in the workspace and I didn’t wanna have a script inside of everyone of them checking if they were touched I could just use a for loop for example:
for i,v in pairs(game.Workspace.Parts:GetChildren())do
if v:IsA('BasePart')then
v.Touched:Connnect(function(Player)
if game.Players:GetPlayerFromCharacter(Player.Parent)then
v.Transparency = 0
end
end)
end
end
If you play a game like Roblox piggy… and watch the guis of the npc and cutscenes, then you should see a little type writing effect. Which is quite helpful if you want to add detail and engage your players.
thank you for the example. do you have one for
‘’‘lua
for i = 1, 10, 3 in pairs
–code
end
‘’’
thank you for this link. it’s very helpful.
I like to use for loops with moving bricks. Here’s an example:
local brick = script.Parent
for i = 0, 21 do
brick.Position = brick.Position + Vector3.new(0,0,0.5)
wait(0.01)
end
or… I use for loops for specific indexes. For example, a fade out script.
for i = 0, 1, 0.1 do
brick.Transpaency = i
wait(0.01)
end
Using tween service for things like that would be way more effective. But for beginners thats not bad!
in that example, is it going to times the position amount by what you put however many times you have?
Yes my apologies, you can use a + instead of a *. LuaGoats, I know haha. I figured if they’re a beginner then I would show them the easy way first.
so for the transparency one it would go up by .1 until it gets to 1? i think im starting to understand it now.
It’s useful for mathematical iterations or sequences that you want to iterate by a specific amount instead of using an epsilon for accuracy, such as a fibonnaci sphere or tilings.
Yes, so for the first loop, the transparency is 0.1, then for the 2nd loop it’s 0.2, the third is 0.3, etc…
yeha i was gonna say haha might crash or something. idk bout crash but it would get pretty crazy.
im starting to understand! breakthroughs bro haha. i love scripting. so what whats a good example if you were getting information? i cant think of a good scenario
Nope, it works totally fine haha. I also made a cool one where you can dim all the lights in your game.
for i = 255, 0, -1 do
game.Lighting.Ambient = Color3.fromRGB(i,i,i)
wait(0.01)
end
oh okay. thank you for the information!
dude you can do -1 as increment and have the start be a high number then low number. thats cool. yo everone is being so helpful. thank you. so much value.
Yessir! A good starting point is make a game where if the player touches a brick, they start to fade away. Or you can do is you can put a bunch of parts in a folder, use a for i, v in pairs loop and have them fade away periodically. That’s a solid example.
oh that’s awesome. i’m starting to understand more. i’m going to write some scripts to better understand for loops. this already has been so helpful. i now understand a lot more.
