- - cell parameters (https://forums.alliedmods.net/showthread.php?t=301562)

Hello, i'm wondering how can i put the parameters for the "WriteShort(Float Fade time) and "WriteShort(Float Fade duration)" for the message "ScreenFade" in the code below

so the native in sma code would be -native send_screen_fade(Index, Float:Fade, Float: Duration, Type, Red, Green, Blue, Alpha)

PHP Code:


		
			
static cell AMX_NATIVE_CALL send_screen_fade( AMX *, cell * pParameters ) {
    if( gpGlobals -> time > 4 && !FNullEnt( INT_TO_EDICT( pParameters[ 1 ] ) ) ) {
        MESSAGE_BEGIN( MSG_ONE_UNRELIABLE, CMessages.screenfade, 0, ENT( INT_TO_EDICT( pParameters[ 1 ] ) ) );
        WRITE_SHORT( 4096 ); // this parameter
        WRITE_SHORT( 2048 ); // this parameter
        WRITE_SHORT( 0 ); // and this parameter
        WRITE_BYTE( pParameters[ 2 ] );
        WRITE_BYTE( pParameters[ 3 ] );
        WRITE_BYTE( pParameters[ 4 ] );
        WRITE_BYTE( pParameters[ 5 ] );
        MESSAGE_END( );
    }

    return 1;
}

so i would send the screen fade like:

PHP Code:


		
			
public func(index)
{
     // for exapmle  
     send_screen_fade(index, 1.0, 0,60, 0x0000, 255, 0, 0, 255) // id, float fade, float duration, fade type , color red, green, blue, alpha


}

Re: cell parameters

Do it just like you would do with any other parameter? Not sure what exactly is the issue here. If you want to get the float value from a parameter you can use amx_ctof function.

Re: cell parameters

Yes, yes solved, i just puted like the other parametters

but i still cannot send the "ScreenFade" message with duration and fade time float

like :

Code:

send_screen_fade(index, 2.00, 0.40....)

i only can:

Code:

send_screen_fade(index, (1<<12), (1<<12), ...

or:

Code:

send_screen_fade(index, (1<<12)*2, (1<<12)*4, ...

PHP Code:


		
			
static cell AMX_NATIVE_CALL send_screen_fade( AMX *, cell * pParameters ) {
    if( gpGlobals -> time > 4 && !FNullEnt( INT_TO_EDICT( pParameters[ 1 ] ) ) ) {
        MESSAGE_BEGIN( MSG_ONE_UNRELIABLE, CMessages.screenfade, 0, ENT( INT_TO_EDICT( pParameters[ 1 ] ) ) );
        WRITE_SHORT( pParameters[ 2 ] ); 
        WRITE_SHORT( pParameters[ 3 ] ); 
        WRITE_SHORT( pParameters[ 4 ] ); 
        WRITE_BYTE( pParameters[ 5 ] );
        WRITE_BYTE( pParameters[ 6 ] );
        WRITE_BYTE( pParameters[ 7 ] );
        WRITE_BYTE( pParameters[ 8 ] );
        MESSAGE_END( );
    }

    return 1;
}

Re: cell parameters

1 << 12 is equal to 4096. So you can multiply 4096 by the number of (floating point) seconds and then round it to the nearest short integer.

Re: cell parameters

Thank you i appreciate your advice.

but how can i round it in cpp like this below writted in pawn

PHP Code:


		
			

stock do_screen_fade(id, Float:fadeTime, Float:holdTime, type, red, green, blue, alpha)

    new fade, hold;
    fade = clamp(    floatround(     fadeTime * float(1<<12)), 0, 0xFFFF    );

    hold = clamp(     floatround(         holdTime * float(1<<12)), 0, 0xFFFF      );
        
    // Message
    message_begin(    MSG_ONE_UNRELIABLE, "ScreenFade", _, id );
    write_short(          fade    );
    write_short(    hold    );
    write_short(    type   );
    write_byte(      red    );
    write_byte(  green    );
    write_byte(    blue    );
    write_byte(     alpha    );
    message_end(    );

Search on Google, that's been answered too many times already.
