я конечно могу ответить но почему бы не открыть хэлп и не посмотреть описание этой функции.
а timer=MilliSecs()
это всё есть в хэлпах Global gfxSparks, frmSparks, tmrSparks
; Standard graphic declaration and double buffering setup
Graphics 640,480,16
SetBuffer BackBuffer()
; Load the imagestrip up and denote the frames 32x32 - for a total of 3 frames
gfxSparks=LoadAnimImage("c:Program FilesBlitzBasicsamplesGraphicsspark.bmp",32,32,0,3)
; We mask the image's color pink to be the 'transparent' color - look at the
; image in your favorite editor to see more why we use masking.
MaskImage gfxSparks,255,0,255
; Loop until ESC
While Not KeyHit(1)
Cls ; Standard clear screen
; The next statment checks to see if 100 milliseconds has passes since we
; last changed frames. Change the 100 to higher and lower values to
; make the animation faster or slower.
If MilliSecs() > tmrSparks + 100 Then
tmrSparks=MilliSecs() ; 'reset' the timer
frmSparks=( frmSparks + 1 ) Mod 3 ; increment the frame, flip to 0 if we are out
End If
DrawImage gfxSparks,MouseX(),MouseY(),frmSparks ; draw the image
Flip ; show the buffer
