How would I make a NPC jump when using :MoveTo()

MrOofBoyPlayz · July 29, 2020, 1:02pm

Hi everybody!

How would I make my NPC jump when using :MoveTo() when the NPC is stuck on a jump-able object (or terrain).

I currently have this game: Free In-Game Admin! [Free Private Servers!] - Roblox

Which has my own piggy character in it but I can’t seem to make him jump when he gets stuck when moving to the nearest player.

Could anyone help?

Here is the follow code:

local npcHRP = script.Parent.HumanoidRootPart

local function GetNearestPlayer(minimumDistance)
    local closestMagnitude = minimumDistance or math.huge
    --minimumDistance is a number in studs
    local closestPlayer
    for i,v in next, game.Players:GetPlayers() do
		local Character = v.Character
		if (Character) then
			local humanoid = Character.Humanoid
			local HRP = Character.HumanoidRootPart
			if (humanoid.Health > 0) then
				local mag = (npcHRP.Position - HRP.Position).Magnitude
				if (mag <= closestMagnitude) then
					closestPlayer = v
					closestMagnitude = mag
				end
			end
		end
	end
	return closestPlayer
end

while wait() do
	local nearPlr = GetNearestPlayer(70)
	pcall(function()
		script.Parent.Humanoid:MoveTo(nearPlr.Character.HumanoidRootPart.Position, nearPlr.Character.HumanoidRootPart)
	end)
end

You use Humanoid:ChangeState()

But how would I know if the NPC needs to jump when it is stuck?

SpacialEthanRB · July 29, 2020, 1:48pm

You would use pathfinding and check the action of one of the waypoints.

Here is a video explaining it:

MrOofBoyPlayz · July 29, 2020, 1:57pm

Yeah but how would I make it path find the player?

MrOofBoyPlayz · July 29, 2020, 2:29pm

I mean, I don’t know how I would make it do this

You could just set the jump bool in Humanoid to true (I forgot its name). It will go back to false on its own too.

MrOofBoyPlayz · July 29, 2020, 2:33pm

I know, I am currently testing what @SpacialEthanRB said.

Theyoloman1920 · July 29, 2020, 2:34pm

You could set the destination to the player’s HumanoidRootPart. If you put it into a run service function, you can get it following you non stop!

MrOofBoyPlayz · July 29, 2020, 2:44pm

Wait… here is my new follow script:

local npcHRP = script.Parent.HumanoidRootPart

local PathFindingServ = game:GetService("PathfindingService")

local npcH = script.Parent.Humanoid
local npcT = script.Parent.Torso

local function GetNearestPlayer(minimumDistance)
    local closestMagnitude = minimumDistance or math.huge
    --minimumDistance is a number in studs
    local closestPlayer
    for i,v in next, game.Players:GetPlayers() do
		local Character = v.Character
		if (Character) then
			local humanoid = Character.Humanoid
			local HRP = Character.HumanoidRootPart
			if (humanoid.Health > 0) then
				local mag = (npcHRP.Position - HRP.Position).Magnitude
				if (mag <= closestMagnitude) then
					closestPlayer = v
					closestMagnitude = mag
				end
			end
		end
	end
	return closestPlayer
end

while wait() do
	local nearPlr = GetNearestPlayer(70)
	pcall(function()
		local path = PathFindingServ:CreatePath()
		path:ComputeAsync(npcT.Position, nearPlr.Character.HumanoidRootPart.Position)
		local waypoints = path:GetWaypoints()

		for _, wp in pairs(waypoints) do
			if wp.Action == Enum.PathWaypointAction.Jump then
				script.Parent.Humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
			end
			print(wp.Action)
			script.Parent.Humanoid:Move(wp.Position)
			script.Parent.Humanoid.MoveToFinished:Wait(2)
		end

		script.Parent.Humanoid:MoveTo(nearPlr.Character.HumanoidRootPart.Position, nearPlr.Character.HumanoidRootPart)
	end)
end

But the NPC/piggy just wants to not live and goes to the edge of the map and falls off.

It doesn’t jump when I put a brick in front of it either

MrOofBoyPlayz · July 29, 2020, 3:03pm

It has only 1 waypoint too which is where the npc starts moving.

Theyoloman1920 · July 29, 2020, 3:13pm

Just follow the tutorial mentioned by @SpacialEthanRB, but use the player’s humanoidRootPart as the destination.

MrOofBoyPlayz · July 29, 2020, 3:14pm

I did! Did you not see the code I sent? Please help

MrOofBoyPlayz · July 29, 2020, 3:15pm

Here is the code again:

local npcHRP = script.Parent.HumanoidRootPart

local PathFindingServ = game:GetService("PathfindingService")

local npcH = script.Parent.Humanoid
local npcT = script.Parent.Torso

local function GetNearestPlayer(minimumDistance)
    local closestMagnitude = minimumDistance or math.huge
    --minimumDistance is a number in studs
    local closestPlayer
    for i,v in next, game.Players:GetPlayers() do
		local Character = v.Character
		if (Character) then
			local humanoid = Character.Humanoid
			local HRP = Character.HumanoidRootPart
			if (humanoid.Health > 0) then
				local mag = (npcHRP.Position - HRP.Position).Magnitude
				if (mag <= closestMagnitude) then
					closestPlayer = v
					closestMagnitude = mag
				end
			end
		end
	end
	return closestPlayer
end

while wait() do
	local nearPlr = GetNearestPlayer(70)
	pcall(function()
		local path = PathFindingServ:CreatePath()
		path:ComputeAsync(npcT.Position, nearPlr.Character.HumanoidRootPart.Position)
		local waypoints = path:GetWaypoints()

		for _, wp in pairs(waypoints) do
			local part = Instance.new("Part")
			if wp.Action == Enum.PathWaypointAction.Jump then
				script.Parent.Humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
			end
			print(wp.Action)
			script.Parent.Humanoid:Move(wp.Position)
			script.Parent.Humanoid.MoveToFinished:Wait()
		end
	end)	
end

I have posted a new post for this issue, see this: PathfindingService is making NPC jump off the edge of map instead of chasing player

graviiity · July 29, 2020, 3:52pm

You’re doing Humanoid:Move(wp.Position), You should be doing Humanoid:MoveTo(wp.Position)

Also, Humanoid.MoveToFinished:Wait() ends up studdering, you might wanna look into using magnitude instead of .MoveToFinished.

MrOofBoyPlayz · July 29, 2020, 5:29pm

Ah thanks, how would I use the magnitude though?

MrOofBoyPlayz · July 29, 2020, 5:33pm

New script but makes the NPC all juttery and delayed:

local npcHRP = script.Parent.HumanoidRootPart

local PathFindingServ = game:GetService("PathfindingService")

local npcH = script.Parent.Humanoid
local npcT = script.Parent.Torso

local function GetNearestPlayer(minimumDistance)
    local closestMagnitude = minimumDistance or math.huge
    --minimumDistance is a number in studs
    local closestPlayer
    for i,v in next, game.Players:GetPlayers() do
		local Character = v.Character
		if (Character) then
			local humanoid = Character.Humanoid
			local HRP = Character.HumanoidRootPart
			if (humanoid.Health > 0) then
				local mag = (npcHRP.Position - HRP.Position).Magnitude
				if (mag <= closestMagnitude) then
					closestPlayer = v
					closestMagnitude = mag
				end
			end
		end
	end
	return closestPlayer
end

while wait() do
	local nearPlr = GetNearestPlayer(70)
	pcall(function()
		local path = PathFindingServ:CreatePath()
		path:ComputeAsync(npcT.Position, nearPlr.Character.HumanoidRootPart.Position)
		local waypoints = path:GetWaypoints()

		for _, wp in pairs(waypoints) do
			local part = Instance.new("Part")
			if wp.Action == Enum.PathWaypointAction.Jump then
				script.Parent.Humanoid.Jump = true
			end
			print(wp.Action)
			script.Parent.Humanoid:MoveTo(wp.Position)
			wait(0.05)
		end
	end)	
end

When he is in water, he doesn’t jump to come out of it.
