How to make parts not "explode" when touching certain parts?

So, I’m currently working on a game with magic, kind of like Arcane Adventures (if you’ve ever heard or played it, it was a great game), and I am working on a kind of boss battle. The boss works and the attacks work and deal damage as intended, but one attack doesn’t work as I intended it to. When testing, the projectiles summoned from the attack would always collide with each other and “explode” before reaching the player, this video will explain what I’m talking about:

Basically, not all projectiles actually reach anywhere close to the player, it instead just hits another then disappears. This is the code of the specific attack showed in the video:

function plasmastorm()
	if debounce == false then
		debounce = true
		local anim = Instance.new("Animation")
		anim.AnimationId = "rbxassetid://3953961100"
		local playanim = npc.Humanoid:LoadAnimation(anim)
    	playanim:Play()
		local BG = Instance.new("BodyGyro", npc.HumanoidRootPart)
		BG.MaxTorque = Vector3.new(250000,250000,250000)
		BG.P = 20000
		BG.D = 150
		spawn(function()
			while wait(.01) do
				BG.CFrame = CFrame.new(npc.HumanoidRootPart.Position, target.HumanoidRootPart.Position - Vector3.new(0,12,0))
			end
		end)
		game.Debris:AddItem(BG,20)
		wait(.5)				
		playanim:AdjustSpeed(0)
		local pcircle = game.Lighting.PlasmaCircle:Clone()
		local pcircle2 = game.Lighting.PlasmaCircle:Clone()
		local pcircle3 = game.Lighting.PlasmaCircle:Clone()
		local pcircle4 = game.Lighting.PlasmaCircle:Clone()
		local pcircle5 = game.Lighting.PlasmaCircle:Clone()
		pcircle.Parent = workspace.Magic
		pcircle2.Parent = workspace.Magic
		pcircle3.Parent = workspace.Magic
		pcircle4.Parent = workspace.Magic
		pcircle5.Parent = workspace.Magic
		spawn(function()
			while wait(.01) do				
				pcircle.CFrame = npc.HumanoidRootPart.CFrame*CFrame.new(0.45,0.5,-4)
				pcircle2.CFrame = npc.HumanoidRootPart.CFrame*CFrame.new(10,8,-4)
				pcircle3.CFrame = npc.HumanoidRootPart.CFrame*CFrame.new(-9,8,-4)
				pcircle4.CFrame = npc.HumanoidRootPart.CFrame*CFrame.new(10,-6.4,-4)
				pcircle5.CFrame = npc.HumanoidRootPart.CFrame*CFrame.new(-9,-6.4,-4)
				
				if pcircle.Orientation ~= npc.HumanoidRootPart.Orientation then
					pcircle.Orientation = pcircle.Orientation + npc.HumanoidRootPart.Orientation
					pcircle2.Orientation = pcircle.Orientation + npc.HumanoidRootPart.Orientation
					pcircle3.Orientation = pcircle.Orientation + npc.HumanoidRootPart.Orientation
					pcircle4.Orientation = pcircle.Orientation + npc.HumanoidRootPart.Orientation
					pcircle5.Orientation = pcircle.Orientation + npc.HumanoidRootPart.Orientation
				end	
			end

end

And this is the damage script, which I believe is the reason why the projectiles are like this:

script.Parent.Touched:Connect(function(hit)
	if hit.Parent.Parent == workspace.Effects or hit.Parent.Parent == workspace.Magic or hit.Parent.Name == script.Parent.Name then return end
	spawn(function()
		local explosion = script.Explosion
       	explosion.Disabled = false
	end)
	
	local hitbox = Instance.new("Part",workspace.Effects)
	hitbox.Transparency = 1
	hitbox.CanCollide = false
	hitbox.Anchored = true
	hitbox.Size = Vector3.new(15,15,15)
	hitbox.Position = script.Parent.Position
	game.Debris:AddItem(hitbox,1)
		
	for i,v in pairs(workspace:GetChildren()) do
		if hit.Parent:FindFirstChild("Humanoid") and hit.Parent.Name ~= "Metta" and (hit.Parent.Torso.Position-hitbox.Position).Magnitude <= 15 then
			if hit.Parent:FindFirstChild("IsPSHit") then return end
			local IsPSHit = Instance.new("BoolValue",hit.Parent)
			IsPSHit.Name = "IsPSHit"
			game.Debris:AddItem(IsPSHit,0.5)
			local Humanoid = hit.Parent:FindFirstChild("Humanoid")
			Humanoid:TakeDamage(220)
			script.Explosion.Disabled = false
		
			if hit.Parent:FindFirstChild("IsPlasmaBurned") then return end
			local IsPlasmaBurned = Instance.new("BoolValue",hit.Parent)
			IsPlasmaBurned.Name = "IsPlasmaBurned"
			game.Debris:AddItem(IsPlasmaBurned,25)
			script.PlasmaBurn.Disabled = false
			local PlasmaBurn = script.PlasmaBurn:Clone()
			PlasmaBurn.Parent = hit.Parent
			game.Debris:AddItem(PlasmaBurn,25)
			wait(1)
			script.Disabled = true
		end	
	end
end)

--[[script.Parent.Touched:Connect(function(hit)
	if hit.Parent.Name ~= "Metta" and hit.Parent:FindFirstChild("Part") then
		script.Explosion.Disabled = false
		script.Disabled = true	
	end
end)]]

Any help?

Have you tried using a simple if statement to make sure that the part it touched isn’t another projectile, and if it isn’t then explode?

For example, if all your projectiles were named “projectile”, you could do something such as

if projectile.Name == "projectile" then
    ...
end

P.S., make sure you format your code correctly! It makes it easier for us to read. To format code, surround it in backquotes, like below:

…lua
code here
…

(replace the periods with backquotes: `)

I have tried that a while ago but the results are the same. The projectiles explode when touching each other, AND the magic circle.

script.Parent.Touched:Connect(function(hit)
	if hit.Parent.Name ~= script.Parent.Name and hit.Parent:FindFirstChild("Part") then -- "script.Parent" is the projectile
		script.Explosion.Disabled = false
		script.Disabled = true	
	end
end)

I believe this is where I’ve done something similar, though I could have done it wrong. The other code that triggers the explosion, the spawn() one also doesn’t work, when trying to add the if statement, my game lags and the error logs are spammed with “Attempt to index nil with ‘FindFirstChild’”
