+# bap-room-packager
+
+This program will take a collection of BAP rooms and automatically package them into BAP's directory format.
+
+## Room Folder Setup
+
+Each room folder must contain at minimum the following images. Every other file is optional.
+
+- ART
+- CREDIT
+- FLOOR
+- ROOF
+- WALL
+
+If the following optional images are not included, they will be automatically filled in with a transparent png file.
+
+- MINI
+- INTERACT
+- LAYER
+
+If the following optional audios are not included, they will be automatically filled in with a silent wav file.
+
+- FOOT
+- MUSIC
+
+Per BAP's readme file, here's a list of accepted file formats. Read BAP's readme file for engine limitations.
+
+- image
+  - PNG
+  - JPG
+  - BMP
+- audio
+  - WAV
+  - MP3
+  - OGG
+  - MIDI
+
+### Room Settings
+
+Each room's settings should be placed in a `ROOM.ini` (or `ROOM.txt`) file. Read BAP's readme file for more details of each setting.
+
+The settings from each `ROOM.ini` file will be used to generate the final `CF.ini` file.
+
+The following is an example `ROOM.ini` file. This is also the file's default settings, so any room with no `ROOM.ini`, or with missing settings from their `ROOM.ini` file, will use these values. The section title does not matter, in this case it's `example`.
+
+```ini
+[example]
+size=1
+speed=1
+FOV=55
+Texture_Repeat=3
+Room_Height=350
+Layer_Frames=1
+Fog_Color=0
+Fog_End=-1
+Mini_speed=1
+```
+
+## Usage
+
+You can view the help screen with `bappackage -h`:
+
+```txt
+Usage of bappackage:
+  -basePath string
+        path to your rooms collection (default "./rooms")
+  -outPath string
+        output path (default "./rooms_out")
+  -roomPerNight int
+        rooms per night (default 4)
+  -splash1 int
+        number of seconds splashscreen 1 will take (default 2)
+  -splash2 int
+        number of seconds splashscreen 2 will take (default 2)
+```
+
+The folder given by `basePath` will contain all of the room folders. For example the following folder structure:
+
+```txt
+rooms
+├───room_one
+│   ├───ART.png
+│   ├───...
+│   └───ROOM.ini
+├───my_second_room
+│   ├───ART.png
+│   ├───...
+│   └───ROOM.ini
+└───third_room
+    ├───ART.png
+    ├───...
+    └───ROOM.ini
+```
+
+The folder given by `outPath` can safely be the folder with BAP. This program will only touch the `DATA/NIGHT_*` folders and the `CF.ini` file in this folder.
+
+`roomPerNight` is used for rooms that do not have an assigned night and room number.
+
+### Assigning Night and Room Numbers
+
+The `ROOM.ini` file accpets 2 extra properties: `night` and `room`. This allows you to organize your room order manually. Any rooms without these properties will only be placed in nights after all manually assigned rooms.
+
+Here is an example of the example `ROOM.ini` above but directly assigned to night 1 room 1.
+
+```ini
+night=1
+room=1
+
+[example]
+size=1
+speed=1
+FOV=55
+Texture_Repeat=3
+Room_Height=350
+Layer_Frames=1
+Fog_Color=0
+Fog_End=-1
+Mini_speed=1
+```
