2017-10-27 02:32:07 +00:00

# Features
(Eventually), the high-level, user-facing features for the game are:
* **Draw your own levels** freehand and then play them like a 2D platformer
game.
* In **Adventure Mode** you can play through a series of official example
levels that ship with the game.
* In **Edit Mode** you can draw a map freehand-style and lay down physical
geometry, and mark which lines are solid or which ones behave like fire.
* Drag and drop **Doodads** like buttons, doors and keys into your level and
link them together so that buttons open doors and levers activate devices.
* In **Play Mode** you can play your level as a 2D platformer game where you
collect keys, watch out for enemies, and solve puzzles to get to the exit.
* Easily **Share** your custom maps with friends.
## Mod-friendly
2019-06-26 01:58:48 +00:00
(Eventually) all these features will support custom content in the
game:
2018-06-17 21:15:59 +00:00
* Users can create **Custom Doodads** to extend the game with a scripting
language like JavaScript. The sprites and animations are edited in-game
in Edit Mode, but the scripting is done in your text editor.
* In **Edit Mode** you can drag custom doodads into your maps.
* To **Share** your maps, you can choose to **bundle** the custom
doodads inside your map file itself, so that other players can play
the map without needing to install the doodads separately.
* If you receive a map with custom doodads, you can **install** the doodads
into your copy of the game and use them in your own maps.

# Built-In Doodads
A brief introduction to the built-in doodads available so far:
- **Characters**
- Blue Azulian: this is used as the play character for now. If
dragged into a level, it doesn't do anything but is affected
by gravity.
- Red Azulian: an example mobile mob for now. It walks back and
forth, changing directions only when it comes across an
obstacle and can't proceed any further.
- **Doors and Keys**
- Colored Doors: these act like solid barriers until the player or
another doodad collects the matching colored key.
- Colored Keys: these are collectable items that allow the player or
another doodad to open the door of matching color. Note that
inventories are doodad-specific, so other mobs besides the
player can steal a key before the player gets it! (For now)
- Electric Door: this mechanical door stays closed and only
opens when it receives a power signal from a linked button.
- Trapdoor: this door allows one-way access, but once it's closed
behind you, you can't pass through it from that side!
- **Buttons**
- Button: while pressed by a player or other doodad, the button
emits a power signal to any doodad it is linked to. Link a button
to an electric door, and the door will open while the button is
pressed and close when the button is released.
- Sticky Button: this button will stay pressed once activated and
will not release unless it receives a power signal from another
linked doodad. For example, one Button that links to a Sticky
Button will release the sticky button if pressed.
