Need help with detecting nearby objects

Help and Feedback Scripting Support
#1

Hey guys,

recently I’ve been making a mesh deformation NPC, and I wanted to make it so that if it is near an object that is in a certain folder, it tweens itself to that object, sort of like tweening to the closest path point. Anyone know how I could manage to script this?

Thanks.

Check these URL:

https://developer.roblox.com/en-us/api-reference/function/Humanoid/MoveTo

And to check of is near use something like this:

local part = script.Parent
local part2 = script.Parent
local magnitude = (part2.Position, part.Position).Magnitude

If the magnitude its a low number, that means that is near. If the magnitude its high number, that means that is far.

wait why would u want it to tween to the certain object when u could use path finding or the moveto function

well, the reason I want to tween to different points is because my “NPC” is currently just a mesh with a humanoid (I should have been more specific), and the map it will be walking around has doors, which would make it unable to find a path using PathfindingService.

#5

You can make an invisible NPC and weld the mesh to the humanoidRootPart.

#6

I’ve tried this, but I don’t know how to get it to detect the nearest path point.

#7

does ur NPC have a Humanoid Root Part, /torso
also is it in R6 or R15?

#8

Currently not, unless the main mesh counts as the root part.

and I don’t think it’s either R6 or R15.

#9

oh then i really dont know, but does it have a primary part?

#10

Yup,

local PathfindingService = game:GetService(“PathfindingService”)
local char = the NPC
local humanoid = char.Humanoid
local destination = EndPartToGo
local path = PathfindingService:CreatePath()

path:ComputeAsync(char.HumanoidRootPart.Position, destination.Position)
local waypoints = path:GetWaypoints()

for _, waypoint in pairs(waypoints) do
if waypoint.Action == Enum.PathWaypointAction.Jump then
humanoid.Jump = true
end
humanoid:MoveTo(waypoint.Position)
end

#12

he said he wanted it to be using tween service, but this is how u properly move an NPC

#13

He can weld the mesh to a NPC or to tween the position to the waypoint.Position.

#14

I think it’d be better to use an actual humanoid, but the script here will make the NPC stuck if there is a door obstructing it’s path.

#15

path finding can detect if a door is in the path heres some waypoints for path finding i did a bit ago:

#16

How can pathfinding detect the door?

#17

im not 100% sure but i think its cus the computer is detecting it

#18

also the type that cant detect the door are those dumb NPCs who only use the move to function

#19

put this script into a normal NPC and add a part into workspace named end part

local PathFindingService = game:GetService("PathfindingService") -- get path finding service
local humanoid = script.Parent.Humanoid
local HRP = script.Parent.HumanoidRootPart
local NPC = script.Parent
local path = PathFindingService:CreatePath()
path:ComputeAsync(HRP.Position, game.Workspace.EndPart.Position) -- computes the path
local waypoints = path:GetWaypoints() -- makes the waypoints(where the NPC walks to.)
for i,v in pairs(waypoints) do -- pair loop
	local waypoint = v
	local showpart = Instance.new("Part", workspace)
	showpart.Size = Vector3.new(1,1,1)
	showpart.Position = v.Position
	humanoid:MoveTo(v.Position) -- moves the NPC to the waypoings
	humanoid.MoveToFinished:Wait() -- waits for the NPC to finish walking to the waypoint
	print(i) -- prints the steps
end

I don’t know if it’s the best thing to do, but long ago I made something like this with Raycast, just send a ray to the front, back, left and right. Hopefully helps.
