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.

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.

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.
