Can we extract more block values?

[lluiscab]

I've been looking at the game code with MCP and I've found some calls to setLightOpacity and setLightLevel. Could this data be extracted?

I'd also like to get whatever the block is transparent or not and if possible, it's bounding box, even tho I think I can get the bounding box from the block model.

I've been trying to read the burger code to try and understand what's happening and how it works but no luck. I'd really appreciate if I could get such data for minecraft-data. Would make updating versions much easier.

For light, it seems possibly useful and probably possible to do fairly easily, assuming that the properties are set by calling methods (if it were overriding methods things would be harder).

Transparency, I'm not sure about. Might be possible or it might not; I haven't looked at the implementation.

For hitboxes, I'm pretty sure that that is done by overriding methods and isn't really feasible to do generally (especially since some blocks such as fences and stairs have very complicated hitboxes that depend on the block state).

Burger's code is definitely rather hard to understand, unfortunately :/. The one thing to note to start with is that it works by following the bytecode and looking at method calls, and that there aren't any names on the methods at this point (so code is a lot harder to follow than in MCP).

I've implemented blast resistance (you didn't ask for it, but it seemed useful) and light level. Opacity seems to be a lot harder to do in 1.13, as it's not actually a fixed property (for instance, ice defers to water), so for the moment I'm not doing it. Transparency also seems hard, since I'm just not sure what the right definition of transparency even is.
