Can't see any reason to use them when you have vector3. Could anyone give me some examples of when you use them and how to use it?
COMMUNITY QUESTION
What are vector2 values used for?
1 answer
In their most basic form, they're used to represent a point on a plane (a plane only consisting of only two dimensions). I found that they are most useful for passing into functions when you already know one of the three coordinates. For instance, if you were making a clone of Terraria on Roblox, but it was in 3D, you'd be creating every block with a z value of 0, so you'd only need a vector2 when spawning one in.
function CreateBlockAt(cords)
--Create a block at (cords.x, cords.y, 0)--
end
They can also be used for UI, but that should be a more obvious use.

Why are you encouraging somebody to get struck by copyright? Bad.

I meant Terraria clone as in a genre of games, such as Terraria, Starbound, Planet Centauri, Junk Jack, etc... The creator of Terraria himself actually said that Terraria is a Minecraft clone, but obviously he meant he was simply inspired by Minecraft when he made it. Besides, I was not even encouraging to begin with, I said "if you were".

never used that before but maybe for 2D games?
vector2 is basically like vector3 but with only 2 axis. I never really needed to use vector 2 but heres a link to a wiki containing more info:https://developer.roblox.com/api-reference/datatype/Vector2
