' - FUZZY SCREEN EFFECT!!!
' - BY ROB OF CYBORNETICS - Jan 94
' - There's a small(?) delay while it generates the fuzz.
' - Alternatively you could use a picture to store the static fuzz.
FUZZ[110,88,100,80,5000,True] : Rem - Not really INTENSE enough.
FUZZ[110,88,100,80,10000,False] : Rem - About the right INTENSITY. No Sound.
FUZZ[110,88,100,80,20000,True] : Rem - A bit too INTENSE.
FUZZ[0,0,320,256,40000,True] : Rem - BIG one. Takes ages. Not INTENSE enough!
Procedure FUZZ[X,Y,WIDTH,HEIGHT,_INTENSITY,SFX]
' - X - X coordinate of fuzz on screen 0
' - Y - Y coordinate of fuzz on screen 0
' - WIDTH - Number of pixels wide the fuzz is (MAX 320)
' - HEIGHT - Number of pixels high (MAX 256)
' - INTENSITY - Number of dots in the fuzz. Works best with high intensity.
' - - Takes ages to generate though, if you have too many.
' - SFX - If True then the fuzz will be accompanied by sound
' - DIFF determines how random each frame is.
' - It's the number of pixels extra added to the width when it's generated.
' - A higer number creates a better effects but needs higer intensity.
DIFF=40
' - Display screen
Screen Open 0,320,256,2,Lowres
Curs Off : Cls 0 : Hide On : Flash Off : Colour 1,$FFF
' - Setup fuzz generation screen
Screen Open 1,320+DIFF,256+DIFF,2,Lowres
Curs Off : Cls 0 : Flash Off : Hide : Colour 1,$FFF
Screen Hide 1
' - Generate the static fuzz
Ink 1
SW=WIDTH+DIFF
SH=HEIGHT+DIFF
For SPOT=0 To _INTENSITY
PX=Rnd(SW)
PY=Rnd(SH)
Plot PX,PY
Next SPOT
Screen 0
' - Bring the noise...
If SFX Then Noise To 15
' - And the fuzzzzz...
Repeat
If SFX Then Play Rnd(10)+80,0
FROMX=Rnd(DIFF)
FROMY=Rnd(DIFF)
Screen Copy 1,FROMX,FROMY,FROMX+WIDTH,FROMY+HEIGHT To 0,X,Y
Until(Mouse Key=1) or(Inkey$<>"") : Rem - Wait for mouse button or any key!
End Proc
