+When a '*' is seen next to an entity's name, that means it is altered compared to its ur-type and is unsaved. There are a number of ways to take care of a '*'. If you do not do one of the below, something on the entity will be lost.
 
-|Left|Select|
+- Changes can be saved to the ur-type. This makes all other entities derived from the ur-type change.
-|Middle|Quick grab|
+- Changes can be saved as a sub ur-type. This creates a brand new type that can then be reused over and over again.
-|Right|Unselect|
+- Changes can be saved by saving the containing ur-type. Ur-types remember variances in the entities it 'owns'.

-== Components
+## Levels?
-Components all have their own set of controls. Many act similar to
-objects. If a component has a position attribute, it will react as
-expected to object grabbing; same with scaling, rotation, and so on.
 
-If a component uses an asset, the asset viewer will serve to pick new
+The concept of a 'level', a collection of spawned entities, is handled simply by creating sub ur-types of an empty entity.

-## Yugine Programming
+In this case, tablebase is saving a modified flipper.
 
-### Object functions
+lvl1
+  %tablebase
+    %flipper
 
-* start(): Called when the object is created, before the first update is ran
+This is ambiguous. lvl1 could be storing the flipper's diff, or tablebase could be. Additionally, tablebase could have a unique flipper, and then lvl1 also alters it.
-* update(dt): Called once per frame
-* physupdate(dt): Called once per physics calculation
-* stop(): Called when the object is killed
-* collide(hit): Called when this object collides with another. If on a collider, specific to that collider
-  - hit.hit: Gameobject ID of what's being hit
-  - hit.velocity: Velocity of impact
-  - hit.normal: Normal of impact
-
-### Colliders
-Colliders visually look different based on their status. Objects can
-be in one of three states
-
-- Dynamic: respond to physics
-- Kinematic: modeled with infinite momentum. An "unstoppable force"
-controlled by a user.
-- Static: modeled with infinite mass. An "immovable object" that
-shouldn't move.
-
-Objects can then have colliders on them, each collider being a sensor,
-or solid. Sensors respond to collision signals, while solid ones also
-do not let objects through.
-
-
-
-### Input
-Input works by adding functions to an object, and then "controlling"
-them. The format for a function is "input_[key]_[action]". [Action]
-can be any of
-
-- down: Called once per frame the key is down
-- pressed: Called when the key is pressed
-- released: called when the key is released
-
-For example, "input_p_pressed()" will be called when p is pressed, and not again
-until it is released and pressed again.
-
-### Your game
-
-When the engine runs, it executes config.js, and then game.js. A
-window should be created in config.js, and custom code for prototypes
-should be executed.
-
-game.js is the place to open your first level.
-
-### Levels
-
-A level is a collection of objects. A level has a script associated
-with it. The script is ran when the level is loaded.
-
-Levels can be added to other levels. Each is independent and unique.
-In this way, complicated behavior can easily be added up. For example,
-a world might have a door that opens with a lever. The door and lever
-can be saved off as their own level, and the level script can contain
-the code that causes the door to open when the lever is thrown. Then,
-as many door-lever levels can be added to your game as you want.
-
-The two primary ways to add objects to the game are World.spawn, and
-Level.add. World.spawn creates a single object in the world, Level.add
-adds an entire level, along with its script.
-
-Levels also can be checked for "completion". A level can be loaded
-over many frames, and only have all of its contents appear once it's
-finished loading. World.spawn is immediate.
-
-Level.clear removes the level from the game world.
-
-.Level scripting
-Each level has a script which is ran when the level is loaded, or the
-game is played. A single object declared in it called "scene" can be
-used to expose itself to the rest of the game.
