What happened?

Hey, congratulations for this amazing library! I have been testing and found that booleans doesnt work as parameter of send (ints and strings work perfectly). The thing is that Unity documentation doesnt seem to support booleans:

SendMessage(objectName, methodName, value);

Where objectName is the name of an object in your scene; methodName is the name of a method in the script, currently attached to that object; value can be a string, a number, or can be empty.

Do you internally cast it to int or something before sending to SendMessage? You say in documentation that booleans can be sent too. I havent seen anything related to this in the issues so it seems strange. Here you have the code in both sides and the exception thrown by Unity:

Uncaught false is does not have a type which is supported by SendMessage.

Below is the code i have used to reproduce the issue, just create a method and pass a boolean

Reproducible test case

React

useEffect(() => {
  const focus = show ? 1 : 0;
  unityContext.send("WebGLEditorManager", "OnEditorChangeFocusInt", focus);
  unityContext.send("WebGLEditorManager", "OnEditorChangeFocusBoolean", show);
}, [show]);

Unity

public void OnEditorChangeFocusBoolean(bool newFocus)
{
    Debug.Log($"Received value {newFocus} on editor change bool");
}

public void OnEditorChangeFocusInt(int newFocus)
{
    Debug.Log($"Received value {newFocus} on editor change int");
}

Would you be interested in contributing a fix?

• yes, I would like to contribute a fix

Sorry i have found they are not supported in the discussion section! Just make sure you update the docs to fix that!!
