Subject: fixed bug with not recognizing ".mode_loop: false" for music
X-Git-Tag: 4.1.1.0~39
X-Git-Url: https://git.artsoft.org/?p=rocksndiamonds.git;a=commitdiff_plain;h=39fb4fecfb8d4647d3563bdb18ce0065f6129522

fixed bug with not recognizing ".mode_loop: false" for music

Before, music was always played in loop mode, even if it was defined
with option "<music>.mode_loop: false".

Now, disabling loop mode for music in config files will indeed cause
music to be played only once.

Note: This commit changed the behaviour of the existing function
"PlayMusic()" (which always played music in loop mode before), which
will now play music only once, while a new function "PlayMusicLoop()"
was added, which always plays music in loop mode.
