heres my ball thing

%n00bish bouncing ball 
setscreen("nocursor") 
setscreen("graphics:400;350") 
var ballx,bally,ballxdir,ballydir:int 
drawfillbox(1,1,400,350,white) 
randint(ballx,0,maxx) 
randint(bally,0,maxy) 

ballxdir:=1 
ballydir:=1 

loop 
    drawfilloval(ballx,bally,5,5,12) 
    delay(1) 
    drawfilloval(ballx,bally,5,5,0) 
    
if ballx>maxx and ballxdir>0 then 
ballxdir:=-ballxdir 
elsif ballx0 then 
ballydir:=-ballydir 
elsif bally maxu or ballu < 0 then
   bally *= -1
end if


bally *= -1 
is the same as
bally := bally * -1

You want the ball to "have a mind of its own" you mean, jumping around like a person, not in an orderly fashion? That would mean you don't need physics, but an animation. like moving a circle around.
