Summary

🤖 Generated by Copilot at 4754fcb

This pull request refactors and improves the code for the graph component, the flow-to-behave transformer, and the camera fade effect. It removes unused imports, simplifies loops, uses helper functions, and switches to more efficient meshes and materials. These changes enhance the performance, readability, and compatibility of the code.

• Simplify and improve the logic for updating the graph component property in BehaveFlow.tsx (link, link)
• Use useHookstate to create local state variables for the user interaction with the Flow component in Flow.tsx (link, link)
• Call onChangeGraph prop whenever the graph or the interaction state changes, but only if the user is not dragging and the mouse is over the pane, in Flow.tsx (link, link, link)
• Simplify the logic for converting the node data to the behave node configuration and parameters in flowToBehave.ts (link)
• Change the geometry, material, and mesh of the entity to use a sphere and a basic material instead of a plane and a shader material, in CameraFadeBlackEffectSystem.ts (link, link)
• Use ComputedTransformComponent to make the entity follow the camera position dynamically, in CameraFadeBlackEffectSystem.ts (link)
• Remove unused imports, constants, and functions from BehaveFlow.tsx, flowToBehave.ts, and CameraFadeBlackEffectSystem.ts (link, link, link, link, link)

We are the masters of the graph, we optimize the flow
We use the hooks and helpers, we make the code run low
We simplify the logic, we transform the nodes with ease
We fade the camera with a sphere, we bring the system to its knees
