getticks <gamevar>

Writes the amount of milliseconds(1 second = 1000 millisecond) since the OS 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
  getticks curtick
  ifvare prevtick -1 setvar tmp 0 else
  {
    setvarvar tmp curtick
    subvarvar tmp prevtick
  }

  mulvar tmp 8800
  addvarvar y tmp
  ifvarg y 13107200 setvar y 0 // 200*65536=13107200
  rotatesprite16 0 y 65536 0 0 0 0 26 0 0 xdim ydim

  setvarvar prevtick curtick

Example code(performance profiling)

gamevar i 0 0
gamevar j 0 0

// Loop from 0 to NUMWALLS-1
state process_normal
  setvar j 0
  whilevarn j 1000
  {
    setvar i 0
    whilevarvarn i NUMWALLS
    {
      addvar i 1
    }
    addvar j 1
  }
ends

// Loop from NUMWALLS-1 to 0
state process_backward
  setvar j 0
  whilevarn j 1000
  {
    setvarvar i NUMWALLS
    subvar i 1
    whilevarn i -1
    {
      subvar i 1
    }
    addvar j 1
  }
ends

/*
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.
