Possible Memory Leak in Canvas about dome

[avivbeeri]

Hi there, thank you for getting in touch. Fortunately, this doesn't appear to be a bug in DOME, just a misunderstanding in how Wren works.

The culprit is the lines you have which look like this:
bird_idle=(value){ bird_idle = value }

These define methods which look like the "setters" you would see other languages, meaning you can do bird.bird_idle = some-value. In the example above, you are actually calling the setter again, recursively, leading to the behaviour you are seeing.

[https://wren.io/classes.html#getters and https://wren.io/classes.html#setters]

Classes and objects in Wren have fields, which are private and can only be accessed inside the object, which is why we have the setters and getters.

A common pattern you see for defining a field, with public setters and getters, looks like this:

bird_idle=(value) { _bird_idle = value } // setter, note the _, to indicate an instance field
bird_idle { _bird_idle } // getter, returning the value of _bird_idle

I hope this helps you with your project.
