(hitTest(x, y, true))

[New2]

Question: Is there any way to make (hitTest(x, y, true)) or perhaps a work around work in 3dfa?
Something other than .collideRect() ?
To determine collision with the actual object and not the bounding box and not for like detecting the distance between balls?
In other words, is there anyway to get (hitTest(x, y, true)) working in 3dfa?


Thanks,
Stephen

I think so but it would require you writing your own function. The one I showed for circle collisions should do what you want with little modification as it's main methods is to determine the distance between two objects. I'm sure if you really needed to dectect collision between two complex shapes it could be done, but basically it would require a fairly complex alogrythm where you check each corner and the path to the next corner of both objects. I can almost visualize it but I'm not a hard core programmer.

Hard to imagine where you'd need this level of detection though. Perhaps if you shared what you are trying to do and perhaps there is a better solution.

Anyway, we need the hitTest() function in 3DFA anyway. Could somebody mail support? I've got no antivirus program, so i aint touching my mail right now... :/

Perhaps you miss understand me. Hittest is RectCOllide.

There really are only two ways in flash to detect collisions one on the bounding rec and the other would be by distance.

Actually there is another way you could do it if you really must detect irregular shaped objects.

You make your object a layer then underneath the visable object you place small rectangular objects that sort of build your object. Then you can test if ANY of those objects collide with the other object then hittest is true.

Lets sat we have a butterfly image. We make some rectangles under it and then assign an array these rectangles we can then do a hit test like for a object ball is colliding with any of the small rectangles we do:

hittest=ball.collideRect (b[0])||ball.collideRect (b[1])||ball.collideRect (b[2])||ball.collideRect (b[3])||ball.collideRect (b[4])
