Using modelsUnderLoc information

Question

Hi, I have properties that I've extracted using the modelsUnderLoc command in a behavior that's used on a 3d sprite.  I need to use the #isectPosition parameter to give a position vector to a model that I place in the world on the fly.  That portion of my script looks like this:
pt = the mouseLoc - point(pSprite.left, pSprite.top)
put sprite(pSprite).camera.modelsUnderLoc(pt, [levelOfDetail: #detailed]).isectPosition
The output from the modelsUnderLoc with the detailed information within the message window looks like this:
-- [[#model: model("036 OTHER Vertebral basilar"), #distance: 37.4722, #isectPosition: vector( -2.8409, -4.5276, -5.8558 ), #isectNormal: vector( -0.2357, -0.2357, 0.9428 ), #meshID: 1, #faceID: 1958, #vertices: [vector( -2.8551, -4.6074, -5.8793 ), vector( -2.8189, -4.4988, -5.8431 ), vector( -2.8913, -4.5712, -5.8793 )], #uvCoord: [#u: 0.6492, #v: 0.2563]]]
How do I get only the #isectPosition vector out of all of that info?

Answer 1

If you attach the following behavior to your 3d sprite, it should output the required information:
on mouseDown(me)
  tempSprite = sprite(me.spriteNum)
  pt = _mouse.mouseLoc - point(tempSprite.left, tempSprite.top)
  m = tempSprite.camera.modelsUnderLoc(pt, [#levelOfDetail: #detailed])
  if m.count then
    -- at least one model has been raycast
    -- output the intersect position of the first model raycast
    put m[1][#isectPosition]
  end if
end mouseDown
