# Example

; Movie Commands Example ; ====================== ; This demonstrates the following commands: ; ; OpenMovie ; MovieHeight ; MovieWidth ; MoviePlaying ; DrawMovie ; Some constants to start with Const WIDTH = 640 Const HEIGHT = 480 ; First of all, set up the graphics Graphics WIDTH, HEIGHT SetBuffer BackBuffer() ClsColor 0,0,0 Color 0,255,0 ; Next, open the movie file. Feel free to change this to an AVI or MPEG file. movie=OpenMovie("media/hat.gif") ; check to see if it loaded okay If movie=0 Then RuntimeError "Error - Movie not loaded!" If Not(MoviePlaying(movie)) Then RuntimeError "Error - Movie not playing!" ;Now determine the size of the movie w=MovieWidth(movie) ; the width of the movie h=MovieHeight(movie) ; the height of the movie ; Now set up the starting position and timing variables x=(WIDTH-w)/2 ; the x position of the movie on screen y=(HEIGHT-h-100)/2 ; the y position of the movie on screen period=100 ; the interval between frames time=MilliSecs() ; the time of the last frame update ; And here's the main loop Repeat ; Wait for the specified period ; GIFs have no timing info, and as such will redraw the next frame on each call to DrawMovie. ; AVIs and MPEGs do have timing info, and as such will redraw the most recent frame on each call to DrawMovie. ; Ergo, this time limiter only has an impact, and is only required for GIFs. Repeat ; do nothing Until MilliSecs()-time>=period time=MilliSecs() ; save the current time for the next frame ; Handle keyboard inputs ; CONTROL adjusts the speed with which we do stuff If KeyDown(29) Or KeyDown(157) Then change=5 Else change=1 End If ; SHIFT means we're dealing with the size If KeyDown(42) Or KeyDown(54) Then If KeyDown(203) And w>change-1 Then w=w-change If KeyDown(205) And x+w+change < WIDTH Then w=w+change If KeyDown(200) And h>change-1 Then h=h-change If KeyDown(208) And y+h+change < HEIGHT Then h=h+change Else ; otherwise it's the position that we're changing If KeyDown(203) And x>change-1 Then x=x-change If KeyDown(205) And x+w+change < WIDTH Then x=x+change If KeyDown(200) And y>change-1 Then y=y-change If KeyDown(208) And y+h+change < HEIGHT Then y=y+change EndIf ; +/- to change the animation speed If ( KeyDown(13) Or KeyDown(78) ) And period>change Then period=period-change If ( KeyDown(12) Or KeyDown(74) ) And period < 500 Then period=period+change ; Redraw the screen, by... Cls ; clear the screen DrawMovie movie,x,y,w,h ; draw the movie ; draw the instructions Text 0,0,"Use the arrow keys to reposition the movie." Text 0,20,"Hold SHIFT with the arrow keys to resize." Text 0,40,"Use + or - or control the animation speed." Text 0,60,"Hold CONTROL to resize, move, or change speed faster." Text 0,80,"Press ESCAPE to exit." Text 0,100,"Current Command Syntax: DrawMovie(movie, " + x + ","+ y + "," + w + "," + h + ")" ; Flip the buffers Flip Until KeyHit(1) ; Escape to exit ; Remove the movie from memory before closing down CloseMovie(movie) End ; bye!
