Did you remember setting the contact delegate inside your scene? Place this line of code inside didMove(to:):

I made some modifications in you code. Problem was in speed definition, in you code speed is changed globally 2 times instead of each time for each ball. Here you go:

So I tried link above which you have mentioned teachable machine
As it turns out model you have exported is from tensorflow.keras and not directly from keras API. These two are different. So while loading it might be using tf.ragged tensors that might not be compatible with keras API.

Soulution to your issue:

Don't import keras directly as your model is saved with Tensorflow's keras high level api. Change all your imports to tensorflow.keras

Change:

I don't know your full code, but let me know if this helps you:

Somewhere before the drawing function

You can start the animation using Clock.schedule_once() as:

If you need precisely the value to be edited, do this:

Well, your restriction rule is incorrect. It says

"RedballContainer is equivalent to a class that only contains RedBallContainers"

It should be:

"RedballContainer is equivalent to a class that only contains RedBalls"

Edit as you found out the above fix does not remove the strange inferred equivalence relation. The reason it's there is somewhat convoluted, but it's roughly this:

1. we know that the domain of contains is Container, so anything that uses a contains property is, by definition, a Container.
2. we know that RedBallContainer is equivalent to anything that contains only RedBalls, so any item that contains only red balls is a red ball container.
3. we also know that RedBallContainer is a subclass of Container.

Now imagine some item that is not a Container. Two options are possible: it either contains something, or nothing. If it does contain something, by definition 1 it still is a Container after all.

However, if it does not contain anything, that means that all the balls it contains are in fact red balls (because none of the zero balls it contains are not red balls)! By our second definition, this thing therefore is a RedBallContainer. By our third definition, it therefore must be a Container after all.

In short, under this set of rules it's not possible for something to not be a Container. Everything is a Container, so Container and Thing are equivalent.

Ah, logic.

To fix, you could change your restriction to say that a RedBallContainer is equivalent to any Container that only contains red balls:

Pretty easy, actually. Just as you subscribe method to listen the predesigned instances' events, you can subscribe via temporary variable references. As long, as the variable holds the reference (or a pointer in C++ terms), you can address the instance and do anything you could do to a predesigned MovieClip:

This SO answer describes how to use a dictionary to map a string to a class.

You can do the same thing with the various strings you store. However, generics are a bit harder to manage.

First, you need to make a Serializer protocol that ResponseArraySerializer conforms to. This protocol will have the required init:
