Source asset formats - Studio-Lovelies/GG-JointJustice-Unity GitHub Wiki

Overview

Various departments work with various file types and tools. This page offers guidelines on how to provide assets to the programmers for integration into Unity.

  • Save your original data in a format that is lossless and easy to work with for you and your department
  • In addition to your original data, offer a separate export to the programming team in the following formats, to enable easy integration of your assets into Unity

Audio

This applies to both sound effects and music.

Property Value
File container .wav / lossless .ogg
Channels 2 (Stereo)
Bits per sample 24
Sample rate 44100

Generally, avoid lossy containers (.mp3) and codecs (Theora).

Music

Seamless loops

To make sure reverb and other decaying effects properly loop, use the following song structure:

  1. intro (optional)
  2. one complete loop
  3. one complete loop again
  4. outro (optional)

Measure the exact timings of the start of 3. and the start of 4.. If you don't have an outro, use the end of 3. instead.

The game will use these as loop markers.

Measure these points in one of two formats:

  • hh:mm:ss.MMM, e.g.:
    • 3.: 00:01:37.123
    • 4.: 00:02:18.342
  • samples
    • 3.: 126345127
    • 4.: 139762386

From DAW to Unity

Complete these steps, to get your song ready for integration in Unity:

  1. Export your song using the properties outlined at the top
  2. Open your song in mp3tag
  3. Select View → Extended Tags and set two tags:
    • LOOP_START with the value of 3.
    • LOOP_END with the value of 4.
  4. Save the file
  5. Upload the file to this Google Drive
  6. Ping a programmer and let them know the song is ready for integration

Sprites

Bachgrounds

Property Value
File ending .png
Width 320px
Height 180px

Sprites should always be 320x180, even if the actual object is smaller.

Animated Sprites

Property Value
Width 320px x Frame Count
Height 180px
File ending .png
Interlacing Non-interlaced
Color space RGB with Alpha

Animated sprites should be 180px in height and 320px in width per frame.
Example: If you need 5 frames, 320px x 5 frames = 1600px. Nodding_ani

To change timings, either change the timings in the Unity editor or repeat the frames inside the source .png file:
