drawing a vector line

[billbones webforumsuser@macromedia.com]

can someone suggest the best way to draw a line between a point and the mouseloc (mouse moving).

Using vectors in flash is perfect but I want to do something similar in Director but am struggling with the vectorlist stuff since the points are not stage relative.

Can someone point me in the right direction . Perhaps their is a technique using the quad (I have tried this but don't like the way the lines are drawing themselves: I'd like a really clean vector line if possible).

Any help or pointers to a tutorial would be much appreciated.

Bill.

"Can someone point me in the right direction . Perhaps their is a technique using the quad (I have tried this but don't like the way the lines are drawing themselves: I'd like a really clean vector line if possible)."

One nice trick is to create a vector shape that has one anchor point at the top left corner of the stage, and the other anchor at the bottom right. You then set the regPoint of the vector to 0,0 and move it to the corner, and then just draw a vector between your starting point and ending point that have direct mappings to the stage. Below is a behavior that you can attach to a vector sprite.

property spriteNum, pFromLoc, pMem, pW, pH

on beginSprite me
pW = the stageRight - the stageLeft
pH = the stageBottom - the stageTop
pMem = sprite(spriteNum).member
pMem.vertexList = [[#vertex: point(0,0)], [#newCurve], [#vertex: point(pW,pH)]]
pMem.regPoint = point(0,0)
sprite(spriteNum).loc = point(0,0)
pFromLoc = point(80,80)
end

on exitFrame me
newLoc = the mouseLoc
-- just to keep it on the stage area run a few quick ifs
if newLoc[1] < 0 then newLoc[1] = 0
if newLoc[1] > pW then newLoc[1] = pW
if newLoc[2] < 0 then newLoc[2] = 0
if newLoc[2] > pH then newLoc[2] = pH
pMem.vertexList = [[#vertex: point(0,0)], [#newCurve], [#vertex: point(200,200)],[#newCurve],[#vertex: pFromLoc], [#vertex:newLoc]]
end

Hope that gets you pointed (so to speak) in the right direction.
