Drawing a curved line

[s7N]

Hi guys,

I need to draw a curve line from point A (fixed) to the mouse loc.
Anyone knows how to script that?

Basically it's for a "fishing" game where my point A is the start of my fishing line, and the mouse will act as the bait. The user will just guide the bait around the screen to catch items. The line will keep redrawing.

Cheers,
Thanks in advance and happy new year!

look in the flash help for the drawing API, there you should find as well the curveTo(); command. Combine that one with lineTo(); and you should have a curve
Very easy to understand in the help

Thanks for the reply.
Hmm.. I managed to draw a straight line from the point till mouse with the lineTo.. But don't really get how the curveTo works..

some little insight:

the flash curveTo method uses the quadratic bezir method:

Thanks thanks. Managed to get it to work, by setting a function to keep drawing a curve line from point to mouse.
Thanks.

and you understand how you influence the curve now?
it´s just like you do in flash with the line and move manipulator, - the line becomes a curve and points (1 edge, not 2 like in freehand, illustrator,...) to where you drag the mouse- same goes the curve to command.

you could add some fx by drawing multiple lines over each other but each one a little bit thinner ( lineStyle(x,...); ) that way you´ll get outlines or even gradients within the stroke if you use enough layered lines

Yea, the two points will act as a anchor point to curve the line. By tweaking the two points and also adding a little bit of random(10), i managed to make it look pretty much like a fishing line in water.

Pls dont say i bumped this... there is an API drawing tool that produces the code for you here, and an API animator that does the same here

Wow, gecko, nice links, very useful applications. Bet it'll come in handy someday.
