Issues with stopping players shooting through walls with a raycasting gun

Help and Feedback Scripting Support

Here is what my gun is currently doing:

Everything works fine until i put the gun into the wall and it starts shooting through it

Here is my code:

local debris = game:GetService("Debris")

local tool = script.Parent  
local gunRemote = tool.GunRemote
local shootSound = tool.GunMesh.Shot  

local config = tool.Configuration
local configValues = {
	MaxDamage = config.MaxDamage.Value;
	MinDamage = config.MinDamage.Value;
	Range = config.Range.Value	;
}

local random = Random.new(tick())
local gunMesh = tool.GunMesh
local att1 = gunMesh.Att1
local beam = gunMesh.Beam

local function createBullet(targetPosition)
	local att1Clone = att1:Clone()
	local beamClone = beam:Clone()

	att1Clone.Parent = workspace.Terrain
	beamClone.Parent = gunMesh
	att1Clone.WorldPosition = targetPosition
	beamClone.Attachment1 = att1Clone

	debris:AddItem(beamClone,0.06)
	debris:AddItem(att1Clone,0.06)
end

local function onShoot(plr, mousePosition)  
	local rayOrigin = tool.RayOrigin.Position  
	local direction = (mousePosition - rayOrigin).Unit * configValues["Range"]  

	local raycastParams = RaycastParams.new()  
	raycastParams.FilterType = Enum.RaycastFilterType.Exclude  
	raycastParams.FilterDescendantsInstances = {tool,plr.Character}  
	
	local raycastResult = workspace:Raycast(rayOrigin, direction, raycastParams)

	if raycastResult then
		createBullet(raycastResult.Position)
		shootSound:Play()  
		local char = raycastResult.Instance:FindFirstAncestorWhichIsA("Model")
		if char then  
			local hum = char:FindFirstChildWhichIsA("Humanoid")  
			if hum then  
				local damage = random:NextInteger(configValues["MinDamage"],configValues["MaxDamage"])  
				hum:TakeDamage(damage)  
			end  
		end  
	end
end  

gunRemote.OnServerEvent:Connect(onShoot)

I’m not sure if I just didn’t code it right, but I tried to make a short raycast from the ray origin to check if it’s raycasting through a part and it didn’t work, here was my attempt:

local obstructionCheck = workspace:Raycast(rayOrigin, direction * 0.1, raycastParams)
if obstructionCheck then
	return
end

Is there any other way to fix this?

You could put the raycast starter position to the tip of the weapon and make it cast another ray in the opposite direction (facing the player’s character). If it hits one of the parts in the equipper’s character (BaseParts, which includes parts and meshes), then it has a high chance of not being clipped through a wall. If it detects something other than the BaseParts of the equipper’s character, then there’s a high chance of it clipping through a wall.
