Start Cam Path (Flowgraph Node)

Overview

• Node Name: Start Cam Path
• Category: once_instant
• File: extensions/flowgraph/nodes/scene/camera/startCamPath.lua

Starts playback of a camera path loaded from a .camPath.json file or created procedurally.

Pin Schema

Input Pins

Output Pins

Behavior

• postInit() - Configures the pathName pin to accept .camPath.json files in the file browser.
• workOnce() - Finds the path via self.mgr.modules.camera:findPath(pathName), starts it with startPath(id, loop), and outputs the path id. Sets the activated impulse.
• work() - Manages the activated impulse flag so it only fires for one frame.

Key Dependencies

• self.mgr.modules.camera:findPath(name) - Resolves a path name to an internal id
• self.mgr.modules.camera:startPath(id, loop) - Begins camera path playback

How It Works

This is the primary node for initiating camera path playback. It accepts either a file path to a .camPath.json or a procedurally generated path name (from Procedural CamPath nodes). The activated impulse fires exactly once on the frame the path starts, then clears. The output id can be wired to Get Cam Path, Restart Cam Path, or Stop Cam Path nodes.

Example Usage

-- Start a camera path from file
-- Wire pathName = "levels/west_coast_usa/art/camera/intro.camPath.json"
-- Wire loop = true for continuous playback
-- Use the id output with Get Cam Path to monitor completion
