Pathfinding AI tries to walk through wall

Help and Feedback Scripting Support
#1

I want to make an AI to find the player at any time and location. The problem is, the AI doesn’t use it’s Pathfinding right. It tries to walk through a wall instead of walking around it…

Script:

local humanoid = script.Parent.Humanoid
local humanoidrootpart = script.Parent.HumanoidRootPart

local PathFindingService = game:GetService("PathfindingService")

local agentparams = {
	AgentRadius = 8,
	AgentHeight = 5,
	AgentCanJump = true
}

local function getPath(destination)	
	local path = PathFindingService:CreatePath(agentparams)
	
	path:ComputeAsync(humanoidrootpart.Position, destination.Position)
	
	return path
end

local function getToPlayers()
	local target
	local players = game.Players:GetPlayers()

	for _, plr in pairs(players) do
		local char = plr.Character
		if char then
			local plrhumanoidrootpart = char:FindFirstChild("HumanoidRootPart")
			if plrhumanoidrootpart then
				if target then
					if (humanoidrootpart.Position - plrhumanoidrootpart.Position).Magnitude < 200 then
						target = plrhumanoidrootpart
					end
				else
					target = plrhumanoidrootpart
				end
			end
		end
	end
	if target then
		local path = getPath(target)

		for i, waypoint in pairs(path:GetWaypoints()) do
			humanoid:ChangeState(Enum.HumanoidStateType.Running)
			humanoid:MoveTo(waypoint.Position)
		end
	end
end

game:GetService("RunService").Stepped:Connect(getToPlayers)

I think your script is running through the waypoints too fast as it is not waiting for the first move command to finish before moving on to the next…

Change it to:

		for i, waypoint in pairs(path:GetWaypoints()) do
			humanoid:ChangeState(Enum.HumanoidStateType.Running)
			humanoid:MoveTo(waypoint.Position)
			humanoid:MoveToFinished:Wait()
		end

Even if you do this , it will not work. It does a line

Try this code out:

local humanoid = script.Parent.Humanoid
local humanoidrootpart = script.Parent.HumanoidRootPart

local PathFindingService = game:GetService("PathfindingService")

local agentparams = {
	AgentRadius = 8,
	AgentHeight = 5,
	AgentCanJump = true
}

local function getPath(destination)	
	local path = PathFindingService:CreatePath(agentparams)

	path:ComputeAsync(humanoidrootpart.Position, destination.Position)

	return path
end

local function getToPlayers()
	local target
	local players = game.Players:GetPlayers()

	for _, plr in pairs(players) do
		local char = plr.Character
		if char then
			local plrhumanoidrootpart = char:FindFirstChild("HumanoidRootPart")
			if plrhumanoidrootpart then
				if target then
					if (humanoidrootpart.Position - plrhumanoidrootpart.Position).Magnitude < 200 then
						target = plrhumanoidrootpart
					end
				else
					target = plrhumanoidrootpart
				end
			end
		end
	end
	if target then
		local path = getPath(target)

		for i, waypoint in ipairs(path:GetWaypoints()) do
			if waypoint.Action == Enum.PathWaypointAction.Jump then
				humanoid.Jump = true
			end
			
			humanoid:ChangeState(Enum.HumanoidStateType.Running)
			humanoid:MoveTo(waypoint.Position)
			humanoid.MoveToFinished:Wait()
		end
	end
end

while true do
	getToPlayers()
	task.wait()
end

The waypoint, is reset every .5 seconds so it looks like the npc isn’t constantly aware of it’s targets position. Would you know how to make the npc chase the targets position without any breaks?

You can use GetActions() which returns the suggested actions from the pathfinding service. They will be in order of how to get to the destination.
