I want to make a similar game to “Zombie Rush” or “Zombie Attack” and currently I’m working on the zombie AI.
The issue
The issue however, is that the zombie does successfully get to me (the closest player) but he doesn’t get “close enough” by that I mean touching my Torso.
I have given the zombie 30 walk speed (default is 16) to demonstrate what is happening.
In the video above you can see the zombie quickly moving to me (the nearest player) and at around 6 studs away from me he starts moving at the same pace as me. (keep in mind that the zombie is almost double as fast as me)
What I want to Achieve
I want to make the zombie be able to fully catch up to me and “attack” me (as in just touching me).
What I have been able to do
I tried looking for solutions in the past, however I haven’t found any solution that has satisfied me yet.
I even tried making the zombie move to a position in front of me by a couple of studs, but this didn’t really work either.
In the script below I have a function to move to the nearest player and what that function does is it ray casts to the targeted player to check if path finding is necessary.
local players = game.Players
local zombie = script.Parent
local humanoid = zombie.Humanoid
local humanoidRootPart = zombie.HumanoidRootPart
local runService = game:GetService("RunService")
local baseparts = zombie:GetChildren()
for _, basepart in pairs(baseparts) do
if basepart:IsA("BasePart") then
basepart:SetNetworkOwner(nil)
end
end
local function findNearestPlayer ()
local allPlayers = players:GetPlayers()
local nearestPlayer = nil
local nearestMagnitude = math.huge
for _, player in pairs(allPlayers) do
local character = player.Character or player.CharacterAdded:Wait()
local magnitude = (character.HumanoidRootPart.Position - humanoidRootPart.Position).Magnitude
if magnitude < nearestMagnitude then nearestPlayer = character nearestMagnitude = magnitude end
end
return nearestPlayer
end
local function rayCastToPlayer (raydestination, rayparms)
local rayorigin = humanoidRootPart.Position
local rayDirection = (raydestination - rayorigin).Unit
local raycast = workspace:Raycast(rayorigin, rayDirection * (rayorigin - raydestination).Magnitude, rayparms)
return raycast
end
local function moveToPlayer (target)
local rayParams = RaycastParams.new()
rayParams.FilterType = Enum.RaycastFilterType.Blacklist
rayParams.FilterDescendantsInstances = {baseparts}
local needToPathfind = true
local rayCast = rayCastToPlayer(target.HumanoidRootPart.Position, rayParams)
if rayCast and rayCast.Instance.Parent == target then needToPathfind = false end
if needToPathfind then
local path = game.PathfindingService:CreatePath({
AgentRadius = 2,
AgentHeight = 4,
AgentCanJump = true
})
path:ComputeAsync(humanoidRootPart.Position, target.HumanoidRootPart.Position)
if path.Status == Enum.PathStatus.Success then
local waypoints = path:GetWaypoints()
if waypoints and waypoints[2] then
local data = waypoints[2]
humanoid:MoveTo(data.Position)
end
end
else
humanoid:MoveTo(target.HumanoidRootPart.Position)
end
end
runService.Heartbeat:Connect(function()
local nearestPlayer = findNearestPlayer()
if nearestPlayer then moveToPlayer(nearestPlayer) end
end)
Any help would be great!
