FLASH: intelligent cursor

[Mountain, Mike J]

Folks


As you can see from the above, I've been working on some means of having an

intelligent cursor which points the direction the mouse is going (numerous

applications in games etc.) but I can only get it to work properly at 90

degree intervals - ie. horizontally and vertically.


The method I'm using is checking it's old position then comparing to see if

it falls within four sectors of an X and Y grid...the centre of the cursor

being (0,0)...so if the new position y>0 x=0 then it points down etc.


I've tried numerous methods of getting the 45 degree angles to work, none of

which work properly, most are pretty "jerky"...so what with all this Bezier

curve business flying around I've decided to dig this one out again and do a

rethink.


So how do I do it? What would be ideal is detecting the new cursor position

and from this calculating the angle with which to rotate the f16

mc.....(with maybe a 10 degree "snap").


If anyone can provide any suggestions I'd be most grateful.


Cheers


Mike M
