Set Camera FOV (Flowgraph Node)

Overview

• Node Name: Set Camera FOV
• Category: repeat_instant
• File: extensions/flowgraph/nodes/scene/camera/setCameraFOV.lua

Sets the camera's Field of View (FOV) to a specified angle. Automatically switches to free camera mode. Restores the original FOV when execution stops.

Pin Schema

Input Pins

Behavior

• work() - Each frame:
  1. Switches to free camera if not already active.
  2. Sets the FOV via core_camera.setFOV(0, value).
• _executionStarted() - Stores the current FOV in self._storedFov for later restoration.
• _executionStopped() - Restores the original FOV from self._storedFov, then clears it.
• drawMiddle() - Displays the current FOV value in the node editor.

Key Dependencies

• commands.isFreeCamera() / commands.setFreeCamera() - Free camera management
• core_camera.getFovDeg() - Read current FOV
• core_camera.setFOV(playerIndex, fovDeg) - Set FOV in degrees

How It Works

The node saves the original FOV when the flowgraph starts and restores it when execution ends - ensuring cinematic FOV changes don't permanently alter the player's view. During execution, it continuously applies the target FOV every frame.

Example Usage

-- Cinematic zoom: wire a number provider to gradually change FOV
-- e.g., start at 60° and interpolate down to 30° for a zoom effect
-- FOV automatically restores when the flowgraph stops
