If someone wants to know how to add HSW-Style.

shavit.inc
(change code to this)

#define MAX_STYLES 8
#define MAX_ZONES 7

// game types
enum ServerGame(+=1)
{
	Game_CSS = 0,
	Game_CSGO,
	Game_Unknown
};

// bhop styles
// enum - for easier customization of settings
enum BhopStyle(+=1)
{
	Style_Forwards = 0,
	Style_Sideways,
	Style_WOnly,
	Style_Scroll,
	Style_400Velocity,
	Style_AOnly,
	Style_DOnly,
	Style_HSW
};

#endif

shavit-core.sp
add this code in line 806 after the STYLE_BLOCK's

// HSW
if(gI_StyleProperties[gBS_Style[client]] & STYLE_HSW_ONLY && !bOnLadder)
{
	if(vel[0] == 0)
	{
		bEdit = true;
		vel[1] = 0.0;
		buttons &= ~IN_MOVELEFT;
		vel[1] = 0.0;
		buttons &= ~IN_MOVERIGHT;
	}
}

btw. ^ this removes the bug/exploit that players hold W and S and can strafe normally like on Forward Style.
