Describe the bug
using unityContent.send does not work inside react hook "useeffect". Method is not called in unity.

unityContent.send(
"TestObject",
"TestMethod",
10
);
}, [updatedParameter]);

Expected behavior
method should be called in unity

I havent used React Hooks yet. But it. seems like useEffect is just an arrow function, it shouldn't matter what you're invoking inside it, right? Are you sure a console log right there shows up in the inspector? Have you tried it outside off a hook?

[DanielAudaptic]

Using the below code, if the button is pressed the "clicked" is printed in the console, and the method is called in unity. But if the useEffect is triggered, the "clicked" is printed but the method in unity is not called.
And after useEffect is called once, and if I then click the button again, the "clicked' is printed but the method is no longer called in unity.

const UnityContainer: React.FC = ({ appState, scenarioState, unityContent }) => {

React.useEffect(() => {
    onClick();
}, [scenarioState]);


const onClick = () => {
    unityContent.send(
        "Cube",
        "TestMethod",
        10
    );

    console.log("clicked");
}


return <div>
    <button onClick={onClick}>Press!</button>
    <Unity unityContent={unityContent} />
    </div>

};

export default UnityContainer;

Looks like the same issue as: #74

[GildedHonour]

Is help needed on this?

[AdhamMoussa]

I checked #74 and I think the problem is initializing unityContent inside the component.
I believe this should be done outside of the component to prevent re-initializing it on every re-render.
If you're doing the same, this maybe the problem u have
(check the parent component that is providing unityContent to UnityContainer)

@AdhamMoussa your are correct! that solved my issues, thank yo ujso much for the assitans!
