Interaction Interface Quick Decision v1.1

Use live gameplay control options to set gameplay elements

This is part of the base code for IIQD. The mouse code was taken from Tanus' SyndicateMod. Also the way
the image coding is done may seem familiar with the Sega500 website tutorials.
Also I highly doubt this is the most efficient way to do this. I think I took the long way around in doing
some of these things. I'll change the textures to ones found within UT2k3 as soon as I get around to it.
Also I'll put the playercontroller which is needed for this to make much sense and the gametype for conclusion. The playercontroller is a
stripped down version of Tanus'. Finally the UnitPress() function in the playercontroller still needs tweaked.

### Dll To Lib, Header File

    //    dinterface_supp.h : supplement header file for dinterface.dll
    //    Author: DLL to Lib version 1.42
    //    Date: Friday, December 12, 2003
    //    Description: The declaration of the dinterface.dll's entry-point function.
    //    Prototype: BOOL WINAPI xxx_DllMain(HINSTANCE hinstance, DWORD fdwReason, LPVOID lpvReserved);
    //    Parameters:
    //            hinstance
    //              Handle to current instance of the application. Use AfxGetInstanceHandle()
    //              to get the instance handle if your project has MFC support.
    //            fdwReason
    //              Specifies a flag indicating why the entry-point function is being called.
    //            lpvReserved
    //              Specifies further aspects of DLL initialization and cleanup. Should always
    //              be set to NULL;

#### Goal

My Goal right now is to fool around with creating an RTS style gametype.
1.Spawn a playercontroller at the playerstart
2.Spawn 6 possessable pawns in a circular position around the playercontrollers start.
3.Create a HUD with a mouse pointer where I can click on the pawns to possess them.
4.When I left click on a pawn it posseses it, when I right click on a place, the pawn will move there.\\

#### CODE

Startmatch()
6 ai controlled pawns
1 playercontroller in spec mode to take care of extra bot
*Pawns stand still, don't shoot each other
*Click on Pawn, selects it
Decide which pawn is selected
InterFace
Make Pawn Look selected
Mouse cursor
On click, trace from viewactor down, if pawn, select pawn
On right click, if pawn is selected, trace down and move pawn to location
Pawn AI - stand still, dont shoot, move when playercontroller tells it to
playercontroller - calls to pawns, must decide which pawn, decide which pawn.function, detect pawn

Wormbo: Maybe you could make a new Pipebomb tutorial page at the UnrealScript Lessons.

Switch`: What's that dinterface_supp.h for?
