Probably

Using QueryEntityOptional directly with the player properties
Character structs are camera structs in build mode
The FlyCam rotation is not updated in build mode, only the camera is

Copying to Plugins folder on build
Registering deterministic game engines automatically
Each event handler is wrapped so if one fails it will still trigger the rest

Not all engine properties are added (yet)
The old block types can be brought back when/if they come back, potentially with different properties

Fixed prefab update for nonexistent blocks
Removed Type from block placed/removed event args
Added test to check the block ID enum (whether it has any extra or missing IDs)
Added test to place every block on the ID enum
Added test to set and verify each property of each block type (type-specific properties are also set when they can be through the API)
Added support for enumerator test methods with exception handling

Also fixed ID of wood material

Most of the removed initialitzers are actually important
Also, the prefab ID was not calculated correctly
Also, the category is 1, not sure why but it is

Replaced typeToGroup with GroupToConstructor
The block object's type is determined by the exclusive group instead of a type parameter
Removed the Specialise() method, the API should always return specialised objects

This fixes the not supported exception but not the game crash that follows

Though the major benefit is only for blocks right now (using initializers)

It broke everything using the type

Regex is great

GetBlockInfo\(this, \((\w+) (\w+)\) ?=> ?\2(.+)\);
GetBlockInfo<$1>(this)$3;

SetBlockInfo\(this, \(ref (\w+) (\w+), \w+ (\w+)\) ?=> \2(.*) = \3,\s*value\);
GetBlockInfo<$1>(this)$4 = value;

Removed all of the different block property getter methods

Added extension methods to query data from ECS objects
Added base class for ECS objects
Added support for representing in-construction ECS objects with an OptionalRef<T>

Except those that actually refer to the game's code

Now it prints them ordered and mostly suitable to be used in code (it only needs a couple replaces)

Added property to get the camera from the player
Removed pointer magic

Just some native code that's totally unnecessary

Removed some command line engines that shouldn't be registered
Fixed registering custom commands - registering it with the existing ones

Added some TODOs as well

And not storing custom block data for now
