isTouching()

The code doesn't work correctly, because a2 isn't a client address but a gentity address.
You need to replace 'clientaddress_to_num' with 'gentityaddress_to_num' to get a valid client number.

Are you sure? This is what my log returns;

clientaddress_to_num = 0, gentityaddress_to_num = 1024

		    int clientnum = clientaddress_to_num(a2);
    int clientnum2 = gentityaddress_to_num(a2);
    printf("clientaddress_to_num = %i, gentityaddress_to_num = %i\n", clientnum, clientnum2);
