Hi! I'm currently messing around with some ideas for a simple Helloween-Screensaver. I want to have a ghost move around on the screen in a "natural looking" way. Graphics 1024,768,16,1 Global bg_ghost ; image handle Global bg_ghostx,bg_ghosty ; cur ghost pos Global bg_ghostwx,bg_ghostwy ; next waypoint bg_ghost=LoadImage("ghost.png") ; Init bg_ghostx=Rnd(0,1023) bg_ghosty=Rnd(0,767) bg_CreateWaypoint() While Not KeyHit(1) ; Main loop Cls ; Waypoint calculation If bg_ghosty > bg_ghostwy Then bg_ghosty=bg_ghosty-1 If bg_ghosty < bg_ghostwy Then bg_ghosty=bg_ghosty+1 If bg_ghostx > bg_ghostwx Then bg_ghostx=bg_ghostx-1 If bg_ghostx < bg_ghostwx Then bg_ghostx=bg_ghostx+1 If (bg_ghostx=bg_ghostwx) And (bg_ghosty=bg_ghostwy) Then bg_CreateWaypoint() DrawImage bg_ghost, bg_ghostx, bg_ghosty ; Output some Debuginfo Color 255,0,0 Text 10,10,"Ghost: "+bg_ghostx+"/"+bg_ghosty Text 10,30,"Next Waypoint: "+bg_ghostwx+"/"+bg_ghostwy Line bg_ghostwx-2, bg_ghostwy, bg_ghostwx+2, bg_ghostwy Line bg_ghostwx , bg_ghostwy+2, bg_ghostwx, bg_ghostwy-2 Flip Wend FreeImage bg_ghost End ; of all being Function bg_CreateWaypoint() ; Create new waypoint to be seeked by the ghost bg_ghostwx=Rnd(0,1023) bg_ghostwy=Rnd(0,767) End Function Ghostimage Any ideas on how to make this movement look better are welcome. Thanks.
