Help with splash code

Help and Feedback Scripting Support

for some reason my splash is way off from were it hit, any help?

local part = script.Parent
local raycastDistance = 100 

part.Touched:Connect(function(hit)
	if not hit.Parent:FindFirstChild("Humanoid") then
		local raycastResult = workspace:Raycast(part.Position, (hit.Position - part.Position).Unit * raycastDistance)
		if raycastResult then
			local hitPart = raycastResult.Instance
			local hitCFrame = hitPart.CFrame
			local randomnum = math.random(1, 3)
			local splashpart = game.ReplicatedStorage.Splash:FindFirstChild("splash"..randomnum):Clone()
			splashpart.Parent = workspace

			local hitLookVector = hitCFrame.LookVector
			local hitUpVector = Vector3.new(0, 1, 0) -- Set the up vector to point upwards
			local hitRightVector = hitLookVector:Cross(hitUpVector)

			splashpart.CFrame = CFrame.new(raycastResult.Position, raycastResult.Position + raycastResult.Normal)
			splashpart.CFrame = splashpart.CFrame * CFrame.Angles(0, math.rad(90), 0)

			splashpart.Color = script.Parent.Color
			script.Parent:Destroy()
		end
	end
end)

it could possibly be something to do with adding the normal to the raycast result position

I don’t see how this would make it not acurate as I researched quite a few devforum posts on trying to make this and I saw them all add the normal

what does adding the normal do exactly?

Im not exactly sure but I believe it is perpendicular to the surface

#6

remove it and see what happens. from there, you may be able to find a solution

I tried that but it did not work

what changed when you got rid of that bit?

It broke and put it in the normal CFrame of the part that was not moved

#10

you made sure you did:

splashpart.CFrame = CFrame.new(raycastResult.Position)

?

No this script is like this tio get the position and rotation not just the position

the normal sets the rotation??

I’m not sure what the problem is, but you could try starting the raycast from above the part by a small offset like so:

local raycastResult = workspace:Raycast(part.Position + Vector3.new(0,1,0), (hit.Position - part.Position).Unit * raycastDistance)

Or you could try to, similar to what @Chiseled_Cheese mentioned, set the CFrame of the splash differently:

splashpart.CFrame = CFrame.new(raycastResult.Position) * CFrame.Angles(0, math.rad(90), 0)

I’m not familiar with the normal vectors, so I’m not sure where the RaycastResult.Normal comes into play…
