MazeGenerator | Blender add-on for generating Mazes | 3D Animation library

It is recommended to avoid over using the force-unwrapping the optional variables.

Even if you're sure, the code might generate nil values in some corner cases that you might have not expected earlier. This will then result in unnecessarily crashing your app and giving a bad user experience.

Try using Optional Binding if-let / guard-let statement to unwrap your optionals safely.

You must initialize data members of reference type with a member initializer list, like this:

Add event to the class using EventEmitter

Your code would look like this:

There are several things wrong with your code:

1. You are never calling checkGameFinished(), so the check and the hiding are never performed
2. By the time your script is executed, the element #mazeComplete does not exist yet. Move your script to the end of the body.
3. In your if conditions, gameComplete = false and gameComplete = true are not comparing the value, but setting it! Change the operator to === to perform a type-safe comparison.

Update:

This answer is wrong at first place. The exception is complaining about accessing the MazeDirectives's transform, not mazeGoal object. But the comments below did give some useful info. So I'm keeping this post for references.

For complete solution, see here.

From the line mazeGoal.transform.SetParent(transform); throws the exception:

This is somewhat brute force, but should do the trick. This routine would be called from the main menu scene before you load the maze scene.

You need to add and remove listeners correctly. For example, in OnEnable() add listeners and in OnDisable() remove them like below:

You can use UnityEvent and UnityAction in unity as well.

Since the connection is proven to be established, I suspect this is an issue of a way you emit the data. Your second parameter hi may not be taken as a data to be transmitted, according to

https://socket.io/docs/server-api/#socket-emit-eventname-args-ack

In my understanding, socket.io emit Object instead of String so can you try this?

To rotate all the cubes at once, I would rotate the parent object they are all attached to. I would simply change the rotation of the parent object in the Start function of your MazeGenerator script, so your Start would look like this:
