Feature Request: Add `getObjectById()` method

[Captain Coder]

Currently, there doesn't seem to be a way for object to easily talk to each other.

For example, I'm trying to make a snake game and I cannot have my "player" check if it is colliding with a "food" because it cannot reference the food object.

Hack:

To get around this, I add this cod to the start method of each of my objects:

  if (!window.myObjects) {
    window.myObjects = {};
  }

This gives me a way to access object. Then, I can capture the scope using anonymous functions:

  head.getPosition = () => getTilePos();
  head.levelUp = () => levelUp();
  window.myObjects.head = head;

Then in my food object, I can reference my head (player) object like this:

  let headPos = window.myObjects.head.getPosition();
  let pos = getTilePos();
  if (pos.x === headPos.x && pos.y === headPos.y) {
    respawn();
    window.myObjects.head.levelUp();
  }

It's a little convoluted. And has a major downside that I cannot really have two "head" objects. To do this, I would need to write a hack to check which one is instantiated first.

Proposal:

• Add an id field to each instance of a GameObject. The id must be unique and can be set manually in the editor when the instance is selected:

By default, the id could be a generated UUID. You would need to have error handling to ensure that two objects don't have the same name / auto rename with -2 or -3 if they do.

• Add a global Scene object that has a getObjectById() method. For example:

  CodeTrain.Scene.getObjectById("SomeIdHere");

I'd love your thoughts!

Thanks for the request, this looks like a great addition! I'll get to work on it.

Resolved with 67f6b09. GameObjects can be assigned IDs in the editor and retrieved with getObjectById(id). See the docs for more details.
