Ai pathfinding open door the wrong way

NongChaITh · October 10, 2023, 6:27pm

This is my first post, don’t mind my Language because i am asian

You can write your topic however you want, but you need to answer these questions:

What do you want to achieve? fix code around 20 round but but i don’t know how to fix, somebody fix it?
What is the issue? here the video
What solutions have you tried so far? I tried to rewhrite but every is same

Here the code in npc model

script

local plrs = game:GetService("Players")
local runs = game:GetService("RunService")
local pfs = game:GetService("PathfindingService")
local ts = game:GetService("TweenService")
local collectSS = game:GetService("CollectionService")

local NPC = script.Parent
local Humanoid = NPC.Humanoids
local HumanoidRootPart = NPC:WaitForChild("HumanoidRootPart")
local BodyColor = NPC:WaitForChild("Body Colors")

repeat
	task.wait()
until workspace:FindFirstChild("Monster")
task.wait(1)
HumanoidRootPart:SetNetworkOwner(nil)

local OriginalSpeed = Humanoid.WalkSpeed

local openSound = script:WaitForChild("Open"):Clone()
local openKnobSound = script:WaitForChild("OpenKnob"):Clone()
local closeSound = script:WaitForChild("Close"):Clone()

	},
	[2] = {
		["Color"] = BrickColor.Green(),
	},
	[3] = {
		["Color"] = BrickColor.Blue(),
	}
}

local function betterWait(number)
	local delta = 0
	
	while delta < number do
		delta += runs.Heartbeat:Wait()
	end
	
	return delta
end

function Play_Sound(id, parent)
	local sound = Instance.new("Sound", parent)
	sound.SoundId = id
	sound.PlayOnRemove = true
	game:GetService("Debris"):AddItem(sound, sound.TimeLength)
end

local rnd = Random.new()
local pickColor = ColorTables[rnd:NextInteger(1, #ColorTables)]
BodyColor.TorsoColor = pickColor.Color

--NPC open door
local params = RaycastParams.new()
params.FilterType = Enum.RaycastFilterType.Blacklist
params.FilterDescendantsInstances = {HumanoidRootPart}
params.IgnoreWater = true

while betterWait(0.5) do
	local direction
	for _, model in pairs(collectSS:GetTagged("Door")) do
		direction = model.TriggeredPart.Position - HumanoidRootPart.Position
	end

	local raycast = workspace:Raycast(HumanoidRootPart.Position, direction, params)

	if raycast then
		local obj = raycast.Instance

				local TriggeredPart = model:WaitForChild("TriggeredPart")

				local currentCFrame = hingeDoor.CFrame
				
				local goal
				local tsInfo = TweenInfo.new(
					1,
					Enum.EasingStyle.Linear,
					Enum.EasingDirection.Out
				)

				if (raycast.Position - TriggeredPart.Position).Magnitude < 5 then

							Play_Sound("rbxassetid://7038967181", hingeDoor)
							goal = {CFrame = currentCFrame * CFrame.Angles(0, math.rad(0), 0)}

Looks like your currentCFrame value is being updated upon each frame. So if your door is already rotated from the last open, it’ll turn another 90 degrees based on where the door’s CFrame is in that exact moment.
Before you run your while loop you need to pre-establish the CFrames of the doors. You can do this by caching them into a table. Then when you need the goal you already have your closed position and just need to offset 90 degrees for the open position (and negate the rotation based on which side they’re opening it from).

Also just a quick note here:

goal = {CFrame = currentCFrame * CFrame.Angles(0, math.rad(0), 0)}

^ This is the same as:

goal = {CFrame = currentCFrame}

I did it and wrote it as you said and it’s the same.

NongChaITh · October 10, 2023, 6:47pm

Is there an example of all the code lines?

Locard · October 10, 2023, 6:51pm

Mind sending in the code that you changed it to? I’ve given you the answer but your application might be different. We can correct it from there.

Looks like you missed this part in what I mentioned. This is the actual fix to your problem, not the code I posted.

Do This BEFORE your while loop:

Make an empty table
For every door, wait for your hinge to pop up and then do table[hingeDoor] = hingeDoor.CFrame

Do this IN your while loop:

The goal’s CFrame will be:

table[hingeDoor] (for the door closing)
table[hingeDoor] * CFrame.Angles(0, math.rad(90), 0) (for the door opening)

Oh, thank you, IT WORK!!!
–My npc is stuck around corner of door, But forget it

NongChaITh · October 11, 2023, 10:06pm

Um, friend?
I open all door in house, but My ai pathfinding open the wrog way again, Here this video :Sory for my video solution:

Lord_BradyRocks · October 11, 2023, 11:30pm

Do you have the script you are using with the above ‘solution’ ?

Thanks
