I am not afraid of fixing anything in scripting but raycasting. I’m trying to make the raycast to check if the fireball is on the ground or not. But even though it is it still wont fire the function.
Please help me. Here’s the code:

local poss = fireball.Position
							local e = -((poss-(Vector3.new(poss.X,game.Workspace.Baseplate.Position.Y,poss.Z)+Vector3.new(0,game.Workspace.Baseplate.Size.Y/2,0))).Magnitude)
							if workspace:Raycast(poss,Vector3.new(0,-1,0)) then
							lightstrike(poss+Vector3.new(0,e,0))
							end

Use RaycastResult for more detailed information, such as the exact point of impact, etc. then go from there.

Btw I found the solution on my own. I just need to set the number 1 to something higher.
