EMEHook hook: (Contributed by Freaka)
|
||
|
|
EmonEngine is used by LoveJuice company and TakeOut. Earlier builds were apparently
|
||
|
|
called Runrun engine. String parsing varies a lot depending on the font settings and
|
||
|
|
speed setting. E.g. without antialiasing (which very early versions did not have)
|
||
|
|
uses TextOutA, fast speed triggers different functions then slow/normal. The user can
|
||
|
|
set his own name and some odd control characters are used (0x09 for line break, 0x0D
|
||
|
|
for paragraph end) which is parsed and put together on-the-fly while playing so script
|
||
|
|
can't be read directly.
