What should I learn for Magic, like Fairytail, lightning, elements?

Hello

Im not really that good at scripting but i hope this helps.

The first things are variables,pretty much texts that store some type of value,for this script we might need to make some variables..

repeat wait() until game.Players.LocalPlayer --i do this because an error would appear.
local Player = game.Players.LocalPlayer
local Char = Player.Character
local Mouse = Player:GetMouse()

So i guess your making a magic,right? well,if you are going to make a projectile,you will need to know how to create a part.

local Flare = Instance.new("Part")
Flare.Parent = game.Workspace

easy,right? Well,in order to make it move,we will have to give it some velocity,so..

local BV = Instance.new("BodyVelocity")
BV.Parent = Flare
BV.Velocity = Mouse.Hit.lookVector * 60 -- this is the direction & speed of the projectile
BV.MaxForce = Vector3.new(1e8,1e8,1e8)

And,to finish it off you might need to add some projectiles to the flare,so you can simply put some in a folder,clone them,and put them in the flare.

local Particle = script.Parent.Folder --if its going to be on a folder..
Particle.Parent = Flare -- placing it on the flare.

so,that should get you started.

Variables are important Learning functions to make things shorter is also helpful. Learning loops can be useful for making explosions,by resizing a Sphere mesh,for example.

local Mesh = Instance.new("SpecialMesh")
Mesh.MeshType = "Sphere"

for i = 0,32 do --this will resize the Sphere mesh over time,making an explosion-like effect.
    Mesh.Scale = Mesh.Scale + Vector3.new(1,1,1)
    wait()
end

Learning evens is also helpful,for example..

Mouse.KeyDown:connect(function(key)
    if key == "q" then
        --Your code here.
    end
end)

This will help making the keys for the moves.

I really hope this helped.
