Matter v0.2.0

[0.2.0] - 2022-06-04

Added

• Added a second parameter to Matter.component, which allows specifying default component data.
• Add QueryResult:snapshot to convert a QueryResult into an immutable list

Changed

• queryChanged behavior has changed slightly: If an entity's storage was changed multiple times since your system last observed it, the old field in the ChangeRecord will be the last value your system observed the entity as having for that component, rather than what it was most recently changed from.
• World and Loop types are now exported (#9)
• Matter now uses both __iter and __call for iteration over QueryResult.
• Improved many error messages from World methods, including passing nil values or passing a Component instead of a Component instance.
• Removed dependency on Llama

Fixed

• System error stack traces are now displayed properly (#12)
• World:clear() now correctly resets internal changed storage used by queryChanged (#13)

Removed

• Additional query parameters to queryChanged have been removed. queryChanged now only takes one argument. If your code used these additional parameters, you can use World:get(entityId, ComponentName) to get a component, and use continue to skip iteration if it is not present.
