I don't understand raycasting

Help and Feedback Scripting Support
#1

I know how to raycast simply but I don’t know how to use it for other stuff. I wanna use it to detect when a part hits the ground or when your in the air.

#2

I learned from it,
you can learn raycasting + how to make a minigun

#3

if you want to detect if a player is in the air, just do this

repeat wait() until script.Parent.Humanoid

script.Parent.Humanoid.StateChanged:Connect(function(oldState, newState)
	if newState == Enum.HumanoidStateType.Freefall then
		print("player is falling")
	end
end)

(LocalScript from StarterCharacterScripts)

script.Parent.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") then
		print("a character touched in the part")
	else
		print("something touched the part")
	end
end)

(Script from Part)

#4

This is deprecated. And I already know how to raycast but I mean how do I apply this knowledge to detect when something hits the floor or is in the air

#5

also if you want to detect every single moment that the player is in the air you must make a loop for it.

#6

can you explain what are you trying to do and not what you need to do? if so I can help you with you’re trying to do and it will help you at your development of the game
