RoomSpawner mask

[TheShuEd]

About the PR

Add tilemask for room spawning.
In the room prototype, you can specify a tile that will be ignored when transferred to the actual game. This is EXTREMELY useful for procedural generation:

right now, in the game all rooms have clear square dimensions, and are copied in their entirety. If we want to have irregularly shaped rooms, we have to do a terrible thing: stitch environment elements into the room itself. As it is done now on VGroid:

this has the disadvantage that these rooms cannot be reused, for example in generation with a different kind of stone and floor.

What I did: I added the ability to specify a tile mask that will be ignored

and now these rooms fit perfectly into any biome or asteroid:

I also removed the restriction that room spawners can only spawn rooms of 1 size. Now they can spawn rooms of any size, although the restriction can be rewritten through prototypes.

Breaking changes

RoomFillComponent ClearExisting field now true by default. This means that all rooms from RoomFillComponent now by default erase all entities underneath them.

[DataField]
public bool ClearExisting = true;

DungeonSystem.Rooms.cs GetRoomPrototype function changed from
public DungeonRoomPrototype? GetRoomPrototype(Vector2i size, Random random, EntityWhitelist? whitelist = null)
to
public DungeonRoomPrototype? GetRoomPrototype(Random random, EntityWhitelist? whitelist = null, Vector2i? size = null)
this function now does not limit the rooms it spawns to a certain default size.

Requirements

• I have read and am following the Pull Request and Changelog Guidelines.
• I have added media to this PR or it does not require an ingame showcase.
