How to get pathfinding AI to play custom walking animation with script?

Help and Feedback Scripting Support
#1

Hello,

So I watched a YouTube tutorial by GnomeCode that covered how to script pathfinding onto a horror AI. I successfully got that part to work. He later showed how to animate it but didn’t really leave clear enough explanation for me to fully understand. I’ve looked at multiple threads that has to do with this issue and the GnomeCode tutorial but they weren’t helpful enough for my situation.

Video of pathfinding working:

The script to it:

local Igor = script.Parent
local humanoid = Igor.Humanoid
Igor.PrimaryPart:SetNetworkOwner(nil)

local function canSeeTarget(target)
	local origin = Igor.HumanoidRootPart.Position
	local direction = (target.HumanoidRootPart.Position - Igor.HumanoidRootPart.Position).unit * 40
	local ray = Ray.new(origin, direction)
	
	local hit, pos = workspace:FindPartOnRay(ray, Igor)
	
	
	if hit then
		if hit:IsDescendantOf(target) then
			return true
		end
	else
		return false
	end
end

local function findTarget()
	local players = game.Players:GetPlayers()
	local maxDistance = 40
	local nearestTarget
	
	for index, player in pairs(players) do
		if player.Character then
			local target = player.Character
			local distance = (Igor.HumanoidRootPart.Position - target.HumanoidRootPart.Position).Magnitude
			
			if distance < maxDistance and canSeeTarget(target) then
				nearestTarget = target
				maxDistance = distance
			end
		end
	end
	
	return nearestTarget
end

local function getPath(destination)
	local PathfindingService = game:GetService("PathfindingService")
	
	local pathParams = {
		["AgentHeight"] = 8,
		["AgentRadius"] = 3,
		["AgentCanJump"] = false
	}
	
	local path = PathfindingService:CreatePath(pathParams)
	
	path:ComputeAsync(Igor.HumanoidRootPart.Position, destination.Position)
	
	return path
end

local function attack(target)
	local distance = (Igor.HumanoidRootPart.Position - target.HumanoidRootPart.Position).Magnitude

	if distance > 2 then
		humanoid:MoveTo(target.HumanoidRootPart.Position)
	else
		local attackAnim = humanoid:LoadAnimation(script.Attack)
		attackAnim:Play()
		target.Humanoid.Health = 0
	end
end

local function walkTo(destination)
	
	local path = getPath(destination)
	
	if path.Status == Enum.PathStatus.Success then
		for index, waypoint in pairs(path:GetWaypoints()) do
			local target = findTarget()
			if target and target.Humanoid.Health > 0 then
				print("TARGET FOUND", target.Name)
				attack(target)
				break
			else
				print("Moving to ", waypoint.Position)
				humanoid:MoveTo(waypoint.Position)
				humanoid.MoveToFinished:Wait()
			end
		end
	else
		humanoid:MoveTo(destination.Position - (Igor.HumanoidRootPart.CFrame.LookVector * 10))
	end
end

function patrol()
	local waypoints = workspace.waypoints:GetChildren()
	local randomNum = math.random(1, #waypoints)
	walkTo(waypoints[randomNum])
end

while wait(0.25) do
	patrol()
end

At the top of the script, I tried changing the

run = 	{	
		     { id = "run.xml", weight = 10 }

part to

run = 	{	
		     { id = "http://www.roblox.com/asset/?id=(theid)", weight = 10 }

as some other stuff below it was listed like this but it didn’t do anything for it.

I’d appreciate any help on how to get that animation to play with the animation script as I’m not very sure how I’ll go about this and this literally the last thing I need to get working to finish part 1/3 of my horror game after several months!

Hey!

First, I’d like to say your character looks very cool.

Is the HumanoidRootPart on your character unanchored? For me, that usually solves the issue.

Thanks for the compliment!

Yes, the HumanoidRootPart of the character is unanchored.

Not so sure it has to do with that but I don’t know what I’m doing wrong with the animation script that it doesn’t want to play the walking animation I made for it. Anything else you may think is happening?

Alright, good to know!

So, in the GnomeCode tutorial model, the character that GnomeCode built is actually in R6. And, it looks like your character is in R15.

There are separate animations scripts for each rig. And, since GnomeCode is using an R6 rig, I don’t believe that it will work for your R15 rig.

Try replacing your animation script with this and changing the IDs to the ones you desire for your character:

-- I grabbed this from my R15 character
local Character = script.Parent
local Humanoid = Character:WaitForChild("Humanoid")
local pose = "Standing"

local userNoUpdateOnLoopSuccess, userNoUpdateOnLoopValue = pcall(function() return UserSettings():IsUserFeatureEnabled("UserNoUpdateOnLoop") end)
local userNoUpdateOnLoop = userNoUpdateOnLoopSuccess and userNoUpdateOnLoopValue

local userEmoteToRunThresholdChange do
    local success, value = pcall(function()
        return UserSettings():IsUserFeatureEnabled("UserEmoteToRunThresholdChange")
    end)
    userEmoteToRunThresholdChange = success and value
end

local userPlayEmoteByIdAnimTrackReturn do
    local success, value = pcall(function()
        return UserSettings():IsUserFeatureEnabled("UserPlayEmoteByIdAnimTrackReturn2")
    end)
    userPlayEmoteByIdAnimTrackReturn = success and value
end
