Raycasting parts at different intervals

#1

I am attempting to create a fireball effect that is created when player activates their sword.

See below.

As seen, the blaze shoots out multiple flames at different seconds.

I tried to attempt this with my code, but it still does not replicate the same behaviour.

function fireAbility()
	tickB = tick();
	local mouseloc = uis:GetMouseLocation()
	local origin = camera:ViewportPointToRay(mouseloc.X, mouseloc.Y)
	local raycastparams


	for i, v in pairs(game.Players:GetPlayers()) do
		if v.Name ~= Player.Name then
			table.insert(IgnoreList, v)
			local character = v.Character
			ignoreAccessories(character)



			raycastparams = RaycastParams.new() 
			raycastparams.FilterDescendantsInstances = {IgnoreList}
			raycastparams.FilterType = Enum.RaycastFilterType.Include;

			local handPosition = Sword:WaitForChild("Handle").Position
			local direction = (mouse.Hit.Position - handPosition).Unit * 30
			local ray = workspace:Raycast(origin.Origin, origin.Direction * 1000, raycastparams)

			local part = Instance.new("Part")
			part.Anchored = true
			part.CanCollide = false 
			part.Position = origin.Origin + (origin.Direction.Unit * 5)
			part.Parent = workspace
			part.Size = Vector3.new(1,1,1)

			local part2 = Instance.new("Part")
			part2.Anchored = true
			part2.CanCollide = false
			part2.Position = origin.Origin + (origin.Direction.Unit * 5)
			part2.Parent = workspace
			part2.Size = Vector3.new(1,1,1)

			local part3 = Instance.new("Part")
			part3.Anchored = true
			part3.CanCollide = false
			part3.Position = origin.Origin + (origin.Direction.Unit * 5)
			part3.Parent = workspace
			part3.Size = Vector3.new(1,1,1)


			local tweenInfo = TweenInfo.new(
				0.6, -- Time
				Enum.EasingStyle.Linear, -- EasingStyle
				Enum.EasingDirection.Out, -- EasingDirection
				0, -- RepeatCount (when less than zero the tween will loop indefinitely)
				false, -- Reverses (tween will reverse once reaching it's goal)
				0 -- DelayTime
			)

			local tweenInfo2 = TweenInfo.new(
				1.5, -- Time
				Enum.EasingStyle.Linear, -- EasingStyle
				Enum.EasingDirection.Out, -- EasingDirection
				0, -- RepeatCount (when less than zero the tween will loop indefinitely)
				false, -- Reverses (tween will reverse once reaching it's goal)
				0 -- DelayTime
			)


			local tweenInfo3 = TweenInfo.new(
				1, -- Time
				Enum.EasingStyle.Linear, -- EasingStyle
				Enum.EasingDirection.Out, -- EasingDirection
				0, -- RepeatCount (when less than zero the tween will loop indefinitely)
				false, -- Reverses (tween will reverse once reaching it's goal)
				0 -- DelayTime
			)

			local tween = TweenService:Create(part, tweenInfo, { Position = origin.Origin + (origin.Direction.Unit) * 50})

			local tween2 = TweenService:Create(part2, tweenInfo2, { Position = origin.Origin + (origin.Direction.Unit) * 50})
			local tween3 = TweenService:Create(part3, tweenInfo3, { Position = origin.Origin + (origin.Direction.Unit) * 50})

			tween:Play()
			tween2:Play()
			tween3:Play()

My attempt below:

It’s because you’re playing all of the tweens at the same time, add some waits in between or smth

tween:Play()
task.wait(1)
tween2:Play()
task.wait(1)
tween3:Play()
#3

it’s because they aren’t using single raycast, but many, see you should create point every 3-4 studs in this case depending on speed and then check, on client you can simply lerp between those points and achieve smooth effect

#4

Sorry for getting back to you so late. I tried this now, I can’t seem to get the desired effect. If I lerp the new part to the ray, the part will only be infront of my camera where I have clicked.

Could you provide a code snippet to help me understand what you mean?

thanks

You don’t lerp anything on server, only cast rays, also code will look like this:

repeat
    local direction = currentPoint + Vector3.new(0,0,-3) -- add your direction

    -- code to raycast ect.

    currentPoint = nextPoint
