Hey,
Right now, my React code has a good few instances of using GameObject.FindObjectOfType<> wrapped in setIntervals as often when I initially try find a script/object, the scene has not finished loading (at least this is my assumption), and thus they remain null.
Is there a particular callback I can hook into to guarantee the scene has loaded so I can remove the setIntervals?

Just use e.g. the onStart
hook Needle Engine Scripting | Needle Engine Documentation
You can also use the <needle-engine loadfinished>
attribute
Thanks Marcel.
Can you please help me understand a bit more about the onStart, specifically the part in the documentation that says its called once per context. Right now from my App.tsx it seems to be getting called 6 times, and I dont really understand why its being called that many times. I want to just be able to know the scene has loaded, and that Unity components can be found. I assumed this would only need to be run once, not six times.
I have attached a screenshot to show what I mean.
How/where do you invoke the onStart hook now in your app? Can you show your script/more context? It it possible that App.tsx is mounted 6 times or that the function from where you call onStart
is called every time your app re-renders? Because if you call onStart multiple times (or add/remove the needle-engine component) your hook will be called once.
Hey Marcus.
Iāve since wrapped this in a use effect. I was calling it outside of any hook in React so it was getting called every re-render.
