fireball.Size=Vector3.new(4.5.6)
did you define fireball as a variable before using it also use commas instead of dots like this Vector3.new(4, 5, 6)
first of all you have to define fireball...
1 | fireball = Instance.new( "Part" , game.Workspace) |
then you did the (4.5.6) part wrong it is actually
1 | fireball.Size = Vector 3. new( 4 , 5 , 6 ) |
full script here
1 | fireball = Instance.new( "Part" , game.Workspace) |
2 | fireball.Size = Vector 3. new( 4 , 5 , 6 ) |
If it is wrong tell me via PM.
