Touched event doesnt always fire?

Help and Feedback Scripting Support

so i added throwable flares to my game, which are supposed to weld to whatever they hit and it works fine, but for some reason the touched event doesnt always fire or it fires with a delay and the flare just falls underground (even though the handle’s CanCollide property is set to true?). i havent had this issue with other sticky grenades like the c4. the touched event is being handled on the server and the flares networkship owner is set to nil (server). any ideas?

Can you please provide the code, I want to make sure that your code isn’t written incorrectly

You should set the network owner to the person who threw the flare.

I haven’t done touches with terrain ever, because I don’t make terrain.

nade.PrimaryPart.Touched:Connect(function(part)

			local charParts = {}
			for i,v in pairs(plr.Character:GetDescendants()) do
				if v:IsA("BasePart") or v:IsA("UnionOperation") or v:IsA("MeshPart") then
					table.insert(charParts,v)
				end
			end

			if not table.find(_G.Blacklist,part) and not table.find(charParts,part) and part.Parent ~= plr.Character and nade.Handle:FindFirstChild("TouchedWeld") == nil and nade.Handle.Anchored == false then
				print("touched")
				if part.Name ~= "Terrain" then
					nade.FX.Rotation = Vector3.new(0,0,-90)
					local weld = Instance.new("WeldConstraint",nade.PrimaryPart)
					weld.Name = "TouchedWeld"
					weld.Part0 = nade.PrimaryPart
					weld.Part1 = part
				else
					nade.FX.Rotation = Vector3.new(0,0,-90)
					nade.PrimaryPart.Anchored = true
					nade:SetPrimaryPartCFrame(CFrame.new(nade.PrimaryPart.Position)*CFrame.Angles(math.rad(nade.PrimaryPart.Rotation.X),math.rad(nade.PrimaryPart.Rotation.Y),math.rad(nade.PrimaryPart.Rotation.Z)))
				end
			end

this is the touched event

There’s a thing in game design where some tools can sometimes pierce through objects by frames.

A kart is going at a forward direction, it moves at a forward velocity. In real life, the kart would hit the wall and crash, but in games, the kart could sometimes pierce and go through the wall.

This has to do with framerate sometimes, and it seems to be what is happening to you.

A solution to it I would suggest you do is to make an external hitbox around the flare, bigger than the flare, and use the hitbox for collision instead. Because if the small tiny flare is the one detecting collisions, there’s a higher chance it will pierce through. With a bigger hitbox collission, that chance should get reduced up until the probability of it happening is not one that happens often in game (we’re talking a flare that is going 5 million km/s)

i think that could have been the problem. i guess the handle part was too small. i made it a little bit bigger and it seems to be better
