Unity collision and feedback[PLEASE HELP]!

Unity Engine
1

Can someone help me please somehow? I have two questions:

  1. I need a virtual scissors (it’s already programmed to move and rotate) to collide with a virtual paper. When the collision is happening i want something to happen, for example the paper to be destroyed(i think this is the simplest way…). The scissors is a Maya object, and the paper is a Unity box.

2)The second phase is that I need Unity to send information to the serial port when a virtual scissors interacts with the virtual paper(I will replace the destroying of the paper with the function that calls the interaction with the serial port). It just has to sent an impulse to a simple DC motor. I read somewhere that you can import a c++ code as a plugin in Unity to interact with haptic devices like PHANTOM. It’s something with"[DLLImport]…" but i’m not sure it works.

Can someone please help me, i need this for my diploma exam at the university, and i am stuck here. I have only a month left…

This should be a good entry point into Plugins. It is a Pro only feature, so you can’t use Unity Indie for it, but it should be able to help.

There should also be a DLLImport sample project on the Unity Site.

I’ve not gotten into Plugins yet so I can’t really help you on the front of actually creating the plugin.

Thank you very much, i hope this will do some work.
You were a great help!
