Set Camera Position (Flowgraph Node)

Overview

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

Sets the free camera's position in world space. Supports two modes: a hardcoded custom position or a dynamic position from an input pin. Preserves current camera rotation.

Pin Schema

Output Pins

Dynamic Input Pins (mode-dependent)

Behavior

• work() - Each frame:
  1. Switches to free camera if needed.
  2. Reads position from the input pin (if mode is "from Pin") or uses the stored custom position.
  3. Calls SetCamera() which uses core_camera.setPosRot() with the new position and the current rotation quaternion.
  4. Outputs the applied position.
• drawCustomProperties() - Editor UI with:
  • Mode dropdown: custom or from Pin
  • Position drag fields (in custom mode)
  • "Set from camera" button to capture current camera position
  • "Preview" button to apply the position
• Serialization - Saves/restores position and mode through _onSerialize/_onDeserialized.

Internals

• self.position - vec3 storing the target position
• self.mode - 'custom' or 'from Pin'
• SetCamera() - Applies position while preserving rotation via core_camera.getQuat()

Key Dependencies

• commands.isFreeCamera() / commands.setFreeCamera() - Free camera management
• core_camera.setPosRot(player, x, y, z, qx, qy, qz, qw) - Sets camera transform
• core_camera.getQuat() - Gets current camera rotation
• core_camera.getPosition() - Gets current camera position (for editor capture)

How It Works

The node offers flexibility through two modes. In custom mode, the position is hardcoded in the node's properties and editable in the flowgraph editor. In from Pin mode, it dynamically creates an input pin to receive position data from other nodes. Both modes preserve the existing camera rotation when updating position.

Example Usage

-- Static camera: use custom mode, set position in editor, wire into scene
-- Dynamic camera: use from Pin mode, wire a vec3 from scene objects
-- Combine with Set Camera Rotation for full camera control

Additional Methods

C:drawMiddle(builder, style)
