//-----------------------------------------------------------------------------
bool UTIL_ShouldShowBlood( int color )
{
	if ( color != DONT_BLEED )
	{
		if ( color == BLOOD_COLOR_RED )

}

static ConVar violence_hblood( "violence_hblood","1", 0, "Draw human blood" );

static ConVar violence_ablood( "violence_ablood","1", 0, "Draw alien blood" );

Examples

//This simply checks the blood color of pHurt
//If their blood is set as DONT_BLEED, it returns false, and skips
//this function. Otherwise it will check the violence convars
//And decide if it should make the blood or not.
if ( UTIL_ShouldShowBlood(pHurt->BloodColor()) )
{
	// Hit an NPC. Bleed them!
	Vector vecBloodPos;

	switch ( BloodOrigin )
	{
		case HUNTER_BLOOD_LEFT_FOOT:
		{
			if ( GetAttachment( "blood_left", vecBloodPos ) )
			{
				SpawnBlood( vecBloodPos, g_vecAttackDir, pHurt->BloodColor(), min( iDamage, 30 ) );
			}
			
			break;
		}
	}
}

//This example just checks the violence convar for BLOOD_COLOR_YELLOW
//which is violence_ablood.
if ( UTIL_ShouldShowBlood( BLOOD_COLOR_YELLOW ) )
