Minds Eye BézierCurve

 

The Minds Eye BézierCurve is an XTRA for use by developers writing lingo for Adobe Director versions 8.5 to 11.5 and currently under Win32 Operating Systems only.

It is very simple and easy to use. It's an Xtra that allows a Lingo programmer to create curved lines based on 4 points (2 end points and 2 control handles).

However, it's not just for drawing curved lines...

Create 2D animations

The Minds Eye BézierCurve XTRA contains 7 functions for working with Bézier curves in different ways. Essentially, a call to one of the handlers generates a list of points. You can use these points to draw curves or create animations. For example, each time the exitFrame handler is called, you can simply set the location a sprite to be the next location in the list (see example at bottom of page).

 

Create 3D geometry and 3D animations

The Minds Eye BézierCurve XTRA also works with 3D data. By supplying four vectors, BézierCurve XTRA returns a list of vectors in 3D space. Also, the BézierCurve XTRA can read XML files that have been exported from 3D Studio MAX using the FREE Minds Eye Shockwave 3D spline exporter (included in the Full Evaluation Bundle).

Example

The following frame behaviour script creates an instance of the BezierCurve Xtra and uses it to move sprite(1) along a Bézier on each call to exitFrame handler.

property ptList
property pInc

on beginSprite me
   pts = [point(290,300), point(300, 50), point(450, 310), point(440, 40)]
   ptList = []
   oBez = new(xtra "mevBezierCurve", "")
   oBez.mevcGet2dBezier(pts[1], pts[2], pts[3], pts[4],  200, ptList)
end

on exitFrame me
   --increment pInc if less than 200 (otherwise reset it back to one)
   if pInc < 200 then
     pInc = pInc + 1
   else
     pInc = 1
   end if

   sprite(1).loc = ptList[pInc]
   go the frame
end
