Request: 3 player horizontal split screen.

[Angel_Mapper]

In GameViewportClient there are several options for split screen, but both of the 3 player options have one player with either the upper or lower half of the screen. If I can I'd like to request an option for 3 player vertical split screen, with each player taking up a third of the screen (left, middle and right). Please let me know if this is reasonable, it'd be a great help to the simulation projects I do at work.

This is for 3P VERT SPLIT but a few changes can make it work for horizontal as well.

1. Add new type of SplitScreenInfo to enum ESplitScreenType so it now looks like this:

enum ESplitScreenType
{
	eSST_NONE,			// No split
	eSST_2P_HORIZONTAL,		// 2 player horizontal split
	eSST_2P_VERTICAL,		// 2 player vertical split
	eSST_3P_FAVOR_TOP,		// 3 Player split with 1 player on top and 2 on bottom
	eSST_3P_FAVOR_BOTTOM,	// 3 Player split with 1 player on bottom and 2 on top
	eSST_4P,				// 4 Player split
	eSST_3P_VERTICAL        // 3 Player Vertical Split each get 1/3 width of screen
};

2. Define it in the DefaultProperties block:

SplitscreenInfo(eSST_3P_VERTICAL)=
{(PlayerData=((SizeX=0.3f,SizeY=1.0f,OriginX=0.0f,OriginY=0.0f),	(SizeX=0.3f,SizeY=1.0f,OriginX=0.3f,OriginY=0.0f),(SizeX=0.3f,SizeY=1.0f,OriginX=0.6f,OriginY=0.0f)))}

3. In GetPixelSizeOfScreen(), add this:

case eSST_3P_VERTICAL:  
		out_Width = Canvas.ClipX * 3;
		out_Height = Canvas.ClipY;
		return;

4. I have no clue what the SafeZones are for, but this how I set them up.
For HasTopSafeZone(), HasBottomSafeZone() and HasLeftSafeZone() I used the same case block as 2P_VERTICAL
For HasRightSafeZone(),

case eSST_3P_VERTICAL:
		return (LocalPlayerIndex < 2) ? false : true;

5. In UpdateActiveSplitscreenType(), I commented out the code existing for case 3 and made it

SplitType = eSST_3P_VERTICAL;

On testing this using DebugCreatePlayer, it shows a 3P Vertical Split with some left-over part of the screen. I tried changing the definition to accommodate the entire screen but all this did was make the game part black even though I can see each player's HUD.

To make the split horizontal all you have to do is change the definition. (hint: SizeY and OriginY take the values instead of SizeX and OriginX)

Hope this helps.

highondota - GameViewportClient is a native class, editing it in that fashion is going to cause issues (likely memory related crashes): the enumerator you've defined now mismatches with the one in the native binary.

Ah I must be going crazy, I think I meant vertical split. Having the players set up across the screen left, middle and right.

I tried this out and I'm amazed it even compiled, but yeah the leftover part of the screen is a dealbreaker unless you know a way to set a monitor to an extremely arbitrary resolution.
