Um Objeto de Entrada representa uma única entrada do usuário, como movimento do mouse, toques, pressionamentos de tecla e muito mais. Ele é criado quando uma entrada começa.
As propriedades deste objeto variam de acordo com o UserInputType.Cada tipo de entrada passará por várias mudanças em seu UserInputState.Durante a vida de uma entrada, outras propriedades que descrevem a entrada podem mudar, como Position e Delta.Pressões de teclado e botões de gamepad terão o configurarde propriedades KeyCode.
Uma vez criado no início de uma entrada, o mesmo objeto persiste e é atualizado até que a entrada termine.Como resultado, você pode rastrear as alterações do Objetousando o evento Changed quando o usuário muda a entrada em questão.Você também pode colocar esses objetos em uma lista de entradas ativas e interagir com o objeto após sua criação por um evento como UserInputService.InputBegan.Isso é principalmente útil para eventos de toque, pois cada ponto de toque terá um objeto de entrada separado.
Veja também:
- ContextActionService , que passa um objeto de entrada para bound funções de manipulação de ação
- UserInputService , cujos eventos e funções muitas vezes usam InputObject
- GuiObject , cujos eventos relacionados à entrada do usuário usam o InputObject

Delta
Um Vector3 descrevendo o Delta (mudança) entre os movimentos do mouse/joystick.
Isso é útil quando usado com o input's position para rastrear a posição e o movimento do mouse/joystick do usuário, como quando você está criando scripts de movimento personalizados ou câmera.Considere alterações de entrada de objetos de rastreamento usando o evento Object.Changed ou quando as alterações de entrada do usuário via eventos, como UserInputService.InputChanged e GuiObject.InputChanged , ocorrem.
Observe que um InputObject correspondente a Enum.UserInputType.MouseButton1 (clique à esquerda) e Enum.UserInputType.MouseButton2 (clique à direita) fornecido por um InputBegan callback não terá seu Delta ou Position atualizado uma vez criado, exceto quando a entrada do mouse termina.Para obter deltas atualizados para entradas de mouse, você deve, em vez disso, referenciar um InputObject de um InputChanged de retorno de chamada ou chamar GetMouseDelta() .No entanto, qualquer InputObjects correspondente a entradas de toque terá seu delta e posição atualizados a cada quadro durante toda a vida útil.

UserInputService.InputChanged:Connect(InputChanged)This example creates a binoculars script that decreases the player's FieldOfView() and MouseDeltaSensitivity() when a player with a MouseEnabled() left mouse clicks. The script also points the player's Camera towards the Vector3 world position of the mouse click.
When the player left mouse clicks again, the player's camera reverts back to the a custom Enum.CameraType with the same field of view and CFrame() as before the player zoomed in with the script.
While the player uses the binoculars, the script locks the player's mouse to the center of the screen by setting the player's MouseBehavior() to LockCenter. The player's camera moves when the player moves their mouse according to the InputObject.Delta property passed by InputChanged() indicating the mouse's Vector2 change in screen position.
In order for this example to work as expected, it should be placed in a LocalScript.

Essa propriedade descreve um valor posicional de Vector3 desta entrada.
Para entrada de mouse e toque, esta é a posição da tela do mouse/toque, descrita nos componentes X e Y.O inseto aplicado a elementos de GUI (como da barra superior) é contado na posição.
Para a entrada da roda do mouse, o componente Z descreve se a roda foi movida para a frente (1), para trás (-1) ou não em tudo (0).
Para Enum.KeyCode, isso indica a posição do Mouse.
Observe que um InputObject correspondente a Enum.UserInputType.MouseButton1 (clique à esquerda) e Enum.UserInputType.MouseButton2 (clique à direita) fornecido por um InputBegan callback não terá seu Delta ou Position atualizado uma vez criado, exceto quando a entrada do mouse termina.Para obter posições atualizadas para entradas de mouse, você deve, em vez disso, referenciar um InputObject de um InputChanged de retorno de chamada ou chamar GetMouseLocation() .No entanto, qualquer InputObjects correspondente a entradas de toque terá seu delta e posição atualizados a cada quadro durante toda a vida útil.

endBy default, Roblox relies on a LocalScript to control the user's camera. However, this script can be overridden with a custom CameraScript. The example below demonstrates how to create a custom script to control the user's camera using many of the UserInputService events.
The script is broken into two parts:
- Mobile camera events, which rely on touch events
- Non-mobile camera events, which rely on keyboard input and tracking the user's movement
First, the camera script needs utility functions to setup the camera and set its Camera.CameraType to Scriptable so that the script can control the camera. It also needs a function to update the camera when it moves, rotates, and zooms.
Using touch events allows us to track user input as they interact with the touchscreen on their mobile device. These events allow us to handle camera movement, rotation, and zoom.
The second half of the code sample adds camera support for players on desktop devices. When input begans, the function Input() checks that the state of the input is Enum.UserInputState.Begin to ignore all keypress inputs other than when the user first presses a key down. When the user presses I and O the camera zooms in and out. When the presses down and moves their left mouse button, the script locks the player's mouse by changing the UserInputService.MouseBehavior property. The camera rotates according to the mouse's change in screen position. When the player moves their character, the camera moves with them.
All of the parts discussed above are combined and shown in the code sample below.

UserInputService.InputChanged:Connect(InputChanged)The following example demonstrates one of many usage examples of handling user input from InputBegan depending on its type.
Handling InputBegan
-- In order to use the InputBegan event, the UserInputService service must be used
local UserInputService = game:GetService("UserInputService")
-- A sample function providing multiple usage cases for various types of user input
UserInputService.InputBegan:Connect(function(input, gameProcessed)
if input.UserInputType == Enum.UserInputType.Keyboard then
print("A key is being pushed down! Key:", input.KeyCode)
elseif input.UserInputType == Enum.UserInputType.MouseButton1 then
print("The left mouse button has been pressed down at", input.Position)
elseif input.UserInputType == Enum.UserInputType.MouseButton2 then
print("The right mouse button has been pressed down at", input.Position)
elseif input.UserInputType == Enum.UserInputType.Touch then
print("A touchscreen input has started at", input.Position)
elseif input.UserInputType == Enum.UserInputType.Gamepad1 then
print("A button is being pressed on a gamepad! Button:", input.KeyCode)
end
if gameProcessed then
print("The game engine internally observed this input!")
else
print("The game engine did not internally observe this input!")
end
end)By default, Roblox relies on a LocalScript to control the user's camera. However, this script can be overridden with a custom CameraScript. The example below demonstrates how to create a custom script to control the user's camera using many of the UserInputService events.
The script is broken into two parts:
- Mobile camera events, which rely on touch events
- Non-mobile camera events, which rely on keyboard input and tracking the user's movement
First, the camera script needs utility functions to setup the camera and set its Camera.CameraType to Scriptable so that the script can control the camera. It also needs a function to update the camera when it moves, rotates, and zooms.
Using touch events allows us to track user input as they interact with the touchscreen on their mobile device. These events allow us to handle camera movement, rotation, and zoom.
The second half of the code sample adds camera support for players on desktop devices. When input begans, the function Input() checks that the state of the input is Enum.UserInputState.Begin to ignore all keypress inputs other than when the user first presses a key down. When the user presses I and O the camera zooms in and out. When the presses down and moves their left mouse button, the script locks the player's mouse by changing the UserInputService.MouseBehavior property. The camera rotates according to the mouse's change in screen position. When the player moves their character, the camera moves with them.
All of the parts discussed above are combined and shown in the code sample below.
