Making NPCs see in a "Tile"/"Block"/"Lane" sight?

[ajsbnfoa (yYouHATEMe)]

If you’ve played the game “Plants vs Zombies” before, there are “towers” that can shoot whenever a zombie infront of them.
Plants vs Zombies is a lane-styled tower defense game.

My current code is simply in these steps:

1. Finding the lane the tower is in.

2. Check if the lane is not empty.

3. Get the enemies inside the lane

4. Check if the distance is lower than the range. (flawed)

   local laneSelected : Folder = workspace.Enemies[config.LaneDefend.Value]
   
   if (#laneSelected:GetChildren() > 0) then
   	for _, enemy : Folder in pairs(laneSelected:GetChildren()) do
   		local Distance = (tower:FindFirstChildOfClass("Model").PrimaryPart.Position - enemy:FindFirstChildOfClass("Model").PrimaryPart.Position).Magnitude
   		if Distance <= config.Range.Value then
   			return true
   		else
   			return false
   		end
   	end
   else
   	return false
   end
   end
   
   

My issue is towers would shoot even if an enemy is behind them and would like replace the code with the tiles as a term of range. Any form of help would- well… Help.

Use a RayCast.

Raycasting | Documentation - Roblox Creator Hub

Or ShapeCast if the enemies are in a different height of the tower.

WorldRoot | Documentation - Roblox Creator Hub

The direction will be something

local range = 50
local direction = PrimaryPart.CFrame.LookVector * range

Sorry for not helping more, I am on phone right now.
