|
|
# A script that generates data files for Android apk
|
|
|
|
|
|
# Below you can find some simple configuration variables.
|
|
# It's allowed to set "all" for KARTS and TRACKS if it's intended to create
|
|
# package with full data.
|
|
# The karts and tracks directories shouldn't exist in ASSETS_DIRS variable
|
|
# because they are handled separately.
|
|
# The TEXTURE_SIZE and SOUND_QUALITY take effect only if DECREASE_QUALITY has
|
|
# value greater than 0.
|
|
# The CONVERT_TO_JPG variable enables converting all images that are safe to
|
|
# convert and keeps other images untouched.
|
|
# The script needs imagemagick, pngquant and ogg utils installed in order to
|
|
# use DECREASE_QUALITY feature
