I have this script that makes the camera follow the player from a top down perspective, but when the camera pass the 55 studs Y position the player die. I don't know how to make the player stop dying.
local Players = game:GetService("Players")
local offset = 0
local wheelpos = 20
local cam = game.Workspace.CurrentCamera
local RunService = game:GetService("RunService")
local mouse = Players.LocalPlayer:GetMouse()
cam.CameraType = "Scriptable"
RunService.RenderStepped:Connect(function()
local Pos = game.Players.LocalPlayer.Character.HumanoidRootPart.Position
local pos = Vector3.new(Pos.X ,wheelpos,Pos.Z)
local lookat = Vector3.new(Pos.x,0,Pos.Z)
cam.CFrame = CFrame.new(pos, -lookat)
end)
mouse.WheelForward:Connect(function()
if offset == 0 then
wheelpos += 5
offset += 1
offset = 0
end
end)
mouse.WheelBackward:Connect(function()
if offset == 0 then
wheelpos -= 5
offset += 1
offset = 0
end
end)
I tried to wait for player to spawn and then run the script but didn't work.

I've tried switching from Vector3 to CFrame and it still hasn't been working. The best I've gotten is the part appearing like 10 feat in the air, this is what I have so far.
local Dog = game:GetService("ReplicatedStorage"):WaitForChild("PetTesting")
local RunService = game:GetService("RunService")
local tweenService = game:GetService("TweenService")
local Petfollow = game:GetService("ReplicatedStorage"):WaitForChild("PetFollow")
game.Players.PlayerAdded:Connect(function(player)
player.CharacterAdded:Connect(function(char)
wait(1)
local dc = Dog:Clone()
dc.Name = "Pet"
dc.Parent = char
local offsetCframe = CFrame.new(0, 0, 0)
dc.CFrame = char:WaitForChild("HumanoidRootPart").CFrame + offsetCframe
dc.Anchored = true
dc.CanCollide = false
dc.Transparency = 0
end)
end)
You can use a bit of CFrame manipulation as described in https://developer.roblox.com/en-us/api-reference/datatype/CFrame. I am not sure if this is the right way of doing this, so please reply if this is incorrect.
local offset = Vector3.new(0, 0, 10)
local newCFrame = humanoidRootPart.CFrame * offset
In a game I'm making, there's a square where the game is happening inside. I want the circles that spawn in to start at the top and travel down to the bottom. In the original program, they travel from left to right. How would I go about this? I don't know how to get it to start at the top and travel down instead of starting at the left and traveling to the right.
Here's the original code (I know it's a lot, sorry). I am trying to help a friend.

I've been working on a script for Roblox. Here's the code:

local char = Player.Character
local hum = char.Humanoid

UIS.InputBegan:Connect(function(input)
if input.KeyCode == Enum.KeyCode.F then
Activation.SoundId = "rbxassetid://1581091676" --Plays Mangekyou Sharingan Activation Sound.
Activation:Play()
wait(0.3)
game.Players.LocalPlayer.Character.Head.face.Texture = "rbxassetid://76285632" --When F is pressed, face texture changes to sharingan decal.
game:GetService("Chat"):Chat(Player.Character.Head, "Mangekyou Sharingan!")
end
end)
UIS.InputBegan:Connect(function(input)
if input.KeyCode == Enum.KeyCode.R then
Activation.SoundId = "rbxassetid://1580990602" --Plays Amaterasu Activation Sound.
Activation:Play()
game:GetService("Chat"):Chat(Player.Character.Head, "Amaterasu!")
local Target = Instance.new("Part") --makes a part
Target.Parent = game.Workspace

Target.Transparency = 1

local Amaterasu = Instance.new("Fire")

if input.KeyCode == Enum.KeyCode.G then
game.Players.LocalPlayer.Character.Head.face.Texture = "rbxassetid://22557247" --When G is pressed, face texture changes back to normal.(leaves face blank isnt working :/)
end
end)
-----------------------------
What I need help with is spawning a the part that parents the amaterasu fire at the current position of my mouse in game. I have researched and tried both Target.Position = Vector3.new(Mouse.target.Position), and Target.Position = Vector3.new(Mouse.Hit).
These both don't work and the end result is the part spawning in the middle of the baseplate no matter where my mouse's position is in game.
What we need is a CFrame. So we'll do:
Target.CFrame = CFrame.new(Mouse.target.Position)
Here is the ticket
local Part = Instance.new("Part",game.Workspace);
Part.CFrame = Mouse.Hit;
Target.CFrame = CFrame.new(Mouse.target.Position)
That Should Work
I am trying to move my hero in a multiplayer setup to the left and right.
I have to squares to initiate move left and move right for a regular crircle on a ground.
I am using AppWarp to initate the multiplayer instance and that is working fine, however I am having trouble on how to communicate the moving of the circle.
Here is my lua:
-- When left arrow is touched, move character left
function left:touch()
motionx = -speed;
end
left:addEventListener("touch",left)
-- When right arrow is touched, move character right
function right:touch()
motionx = speed;
end
right:addEventListener("touch",right)
-- Move character
local function movePlayer (event)
appWarpClient.sendUpdatePeers(tostring(player.x))
end
Runtime:addEventListener("enterFrame", movePlayer)
-- Stop character movement when no arrow is pushed
local function stop (event)
if event.phase =="ended" then
motionx = 0;
end
The keyline here is
appWarpClient.sendUpdatePeers(tostring(player.x))
with this I send the current X position of my hero (the circle) and in my warplisteners I pick it up like so:
function onUpdatePeersReceived(update)
local func = string.gmatch(update, "%S+")
-- extract the sent values which are space delimited
--local id = tostring(func())
local x = func()
statusText.text = x
player.x = x + motionx
end
When I start the game on 2 clients I can start moving the ball but it is wobbeling back and forth between 62 units, wich i guess is my speed
speed = 6; -- Set Walking Speed
if I change this:
function onUpdatePeersReceived(update)
local func = string.gmatch(update, "%S+")
-- extract the sent values which are space delimited
--local id = tostring(func())
local x = func()
statusText.text = x
player.x = x + motionx
end
to this:
function onUpdatePeersReceived(update)
local func = string.gmatch(update, "%S+")
-- extract the sent values which are space delimited
--local id = tostring(func())
local x = func()
statusText.text = x
player.x = player.x + motionx
end
(last line before "end")
player.x = player.x + motionx
instead of
player.x = x + motionx
The coordinates gets updated but the hero only moves on one of the screens.
Any idea how to implement a better movement system that moves my hero on both clients at the same time?
Kind regards
edit:
Added if-else, it was pending between +-speed and 0 since the speed is 0 when hero is stopped.
if(motionx ~= "0") then
player.x = player.x + motionx
statusText.text = "motionx ~= 0"
elseif(motionx == "0") then
player.x = player.x
else
statusText.text ="Something went horribly wrong"
end

The error message is perfectly clear -- the variable sprite used at this line:
local bird1 = sprite.birdSheet( birdSet )
has a nil value, meaning it has not been initialized or was set to nil. You need to show the earlier code where you should have set it up.
(After OP updates)
I think this line
require "sprite"
should actually be
sprite = require "sprite"
