SetMaskColor problem

Please Help me! There is my code

 		AutoMidHandle True 
	     Type player
	               	   Field x#,y#,xspd#,yspd#,friction#=0.004,acceleration#=0.008,spdvector#,direction#,maxspd#=0.6
				   	   Field turnspd#,turnaccel#=0.1,turnmax#=0.7,turnfriction#=0.04, life
					    Field entity=LoadImage("player.png")
					Method create()
						x=400 ; y=300 ' ñîçäàíèå ïëååðà â öåíòðå ýêðàíà
					End Method
					
		 Method update()
						If KeyDown(Key_up)
							 xspd:+Cos(direction)*acceleration	 
							 yspd:+Sin(direction)*acceleration
						End If
						If KeyDown(Key_down)
							 xspd:-Cos(direction)*acceleration
							 yspd:-Sin(direction)*acceleration
						End If
						spdvector=Sqr(xspd*xspd+yspd*yspd) 'âåêòîð ñêîðîñòè
									If spdvector > 0
										xspd:-(xspd/spdvector)*friction
										yspd:-(yspd/spdvector)*friction
									End If
									
									If spdvector>maxspd
										xspd:+(xspd/spdvector)*(maxspd-spdvector)
										yspd:+(yspd/spdvector)*(maxspd-spdvector)
									End If
							If spdvector<0.2		  ' óñëîâèå "ñêîëüæåíèÿ"
								turnfriction=10
							Else
								turnfriction=0.04
						    End If
							      	x:+xspd
									y:+yspd
						DrawText (spdvector,15,15)
						
						If KeyDown(KEY_RIGHT) turnspd:+turnaccel
						If KeyDown(KEY_LEFT) turnspd:-turnaccel
						
		  If turnspd>turnmax turnspd=turnmax
		  If turnspd<-turnmax turnspd=-turnmax	
		  direction:+turnspd
		  If direction>360 direction:-360
		  If direction<0 direction:+360				
	      If turnspd>turnfriction Then turnspd:-turnfriction
		  If turnspd<-turnfriction Then turnspd:+turnfriction
	      If turnspd < turnfriction And turnspd > -turnfriction Then turnspd=0		
							SetScale 0.3,0.3
							SetRotation direction
							DrawImage entity,x,y
							SetRotation 0
							SetScale 1,1
	 End Method
				  
		EndType 
		
		Graphics 800,600,32
		water=LoadAnimImage("wateranim.jpg",124,124,0,23)
		AutoImageFlags (MASKEDIMAGE)
		SetMaskColor (0,0,0)
		player1:player=New player
		player1.create()
		Repeat
		Cls
		frame=MilliSecs()/92 Mod 23
		TileImage (water,0,0,frame)
		player1.update()
		Flip
		Until KeyHit(Key_Escape)

Who know, why setmaskcolor don't work?
