getticks <gamevar>
Writes the amount of milliseconds(1 second = 1000 millisecond) since the game started to <gamevar>. This clock isn't synced with the game which means that it must not be used for the gameplay if the mod is supposed to work in multiplayer. This command is useful for visual animating(especially in EVENT_DISPLAYMENU) and for performance profiling.
Example code(animation)
gamevar prevtick -1 0
gamevar curtick 0 0
gamevar tmp 0 0 // =curtick-prevtick
gamevar y 0 0
onevent EVENT_DISPLAYMENU

/*
output
CONLOGVAR: L=1266 NUMWALLS (read-only) (Global) =14793
CONLOGVAR: L=1272 val2 (Global) =1628 // normal
CONLOGVAR: L=1278 val2 (Global) =1285 // reverse
It shows how that processing in reverse order is faster.
