Can i detect multi-touch inside a polygon region?

I've drawn 4 polygon regions on my screen to split my stage up into 4 areas (4 inverted triangles).

I want to detect which region a touch occurs, is this possible?

My only use of multi-touch has been detecting if the touch has been inside of x y coordinates in a square/rectangle.

Thanks

Can somebody answer this pliz? I also want to know how to do that!

Nortfield82 did you find out how this can be accomplished?

thanks

here is ther theory for it > http://stackoverflow.com/questions/2049582/how-to-determine-if-a-point-is-in-a-2d-triangleI havenf had the time to work this out yet tho

Thank you TheIndieStation but after reading up about regions and people not advising on using them I think I'll just create transparent actors attached to my actor and when touched it will determine the movement. You think it will work? Thanks

Hi Maruda,  yes that's the option I went for in the end.  Works just the same

Northfield82 idea is good but execution . . .   any pointers?

How can I control one actor when the other is being pressed on ?

And how do you attach one actor to the other? I'm using "follow target" from forge but cant tell if itsworking.

thanks in advance for help
