OK, I have created custom nightvision which consists of TE_DLIGHT + once sent ScreenFade message.But I am facing one problem, my nightvision conflicts with flashbangs.Whenever player is flashed, he can just turn on my nightvision and flash effect disappears.How can i prevent that?

I thought about blocking ScreenFade effect when player is flashed, but more problem appears.How to get whenever player is flashed.

I suppose through ScreenFade event/message hooking.Or maybe there is any private data offset, something like m_fIsFlashed?

This is piece of code I have right now:

#include < amxmodx >
#include < fakemeta >
#include < hamsandwich >

new bool:g_fNightVisionEnabled[ 33 ];

const FFADE_STAYOUT = 0x0004;

#define TASK_NVG    19368
#define ID_NVG    ( taskid - TASK_NVG )

public plugin_init( )
{
    register_clcmd( "nightvision",    "_nightvision_"    );
}

// ... code

public _nightvision_( Player )
{
    if( !FBitSet( g_afPlayerFlags[ Player ], PF_ALIVE )
        return PLUGIN_CONTINUE;
        
    if( FBitSet( g_afPlayerFlags[ Player ], PF_ZOMBIE )
    {
        g_fNightVisionEnabled[ Player ]    = !( g_fNightVisionEnabled[ Player ] );
        
        if( g_fNightVisionEnabled[ Player ] )
        {
            MSG_ScreenFade( Player, 1 << 12, 1 << 12, FFADE_STAYOUT, 253, 95, 95, 125 );
        
            set_task( 0.1, "TASK_EnableNVG", Player + TASK_NVG, _, _, "b" );
            emit_sound( Player, CHAN_ITEM, "items/nvg_on.wav", 0.94, ATTN_NORM, 0, 98 );
        }
        else
        {
            emit_sound( Player, CHAN_ITEM, "items/nvg_off.wav", 0.94, ATTN_NORM, 0, 98 );
        }
        
        return PLUGIN_HANDLED;
    }
    
    return PLUGIN_CONTINUE;
}

// ... more code...

public TASK_EnableNVG( taskid )
{
    if( !FBitSet( g_afPlayerFlags[ ID_NVG ], PF_ALIVE ) || !g_fNightVisionEnabled[ ID_NVG ] )
    {
        MSG_ScreenFade( ID_NVG );
