How to use Vector3?

Help and Feedback Scripting Support
#1

so I’m making a enchanted forest, and I added fireflies and I was hoping I could use vector3 to make them bob up and down lightly and maybe spin in a circle slowly. I’m not 100% sure if I use vector3 or something else. Please help.

It would probably better to use TweenService in your case, it’s a little easier to get the effects you mentioned using it. There are also plenty of resources on it

You can. math.sin would most likely be your best friend, alongside math.cos if you want a bobbing and circle motion. Another way you could do the bobbing is like how Jay mentioned, which is using TweenService. Vector3 would most definitely work.

ok, but the thing is I know nothing on scripting, I can do like the real real basic stuff like change a brick colour, so I have no idea what to do with those.

Then you should search up some tutorials or look on the ROBLOX wiki. It’s very helpful to look in those places.

You can make a bobbing effect using TweenService. A quick and easy one would be like this.

local TweenService = game:GetService("TweenService")
local HEIGHT = 5
local TIME = 1
local Direction = 1
while true do
    Direction = Direction == 1 and 0 or 1
    local Tween = TweenService:Create(part, TweenInfo.new(1), {CFrame = part.CFrame * CFrame.new(0, (Direction == 1 and HEIGHT or -HEIGHT), 0)})
    Tween:Play()
    Tween.Completed:Wait()
end

This should work.

it says line 7 is wrong, and since I have no idea what I’m doing I don’t know how to fix it.

Oops. Made a typo. I wrote “CFame” instead of “CFrame”.

Edit: There was also another typo. Everything should be fixed. I edited my last post so you can try copy and pasting the code to see if everything works fine now.

Did you fix the bracket? (30 chars)

#13

yes now its complaining about a nil value

edit: I think I know why, let me check

#14

its saying part is a nil value

#15

You have to replace “part” with what ever your using.

#16

that’s what I thought was wrong but It still didn’t work, the part I wanted to use was called fireflys1, though that’s a model so would that still work?

this is why i dont do scripting :neutral_face:

#17

If its a model then it won’t work as easily with a part. Your going to have to tween the PrimaryPart. Everything else in the model should be welded to the PrimaryPart.

This works fine with a part:

k ill try, just beware ill probably stuff it up
