How does TE_LIGHTNING work?!

OciXCrom · **Author**

I tried many parameters, tried searching everywhere, but I didn't manage to get this thing to work.

PHP Code:


			
message_begin(MSG_ALL, SVC_TEMPENTITY)

write_byte(TE_LIGHTNING);

write_coord(pos1[0]);

write_coord(pos1[1]);

write_coord(pos1[2]);

write_coord(pos2[0]);

write_coord(pos2[1]);

write_coord(pos2[2]);

write_byte(10);

write_byte(10);

write_byte(2);

write_short(beam); // "sprites/laserbeam.spr"

message_end();

Nothing happens when I execute this code. Tested both on 1.8.2 and latest 1.8.3 dev build.
pos1 and pos2 are working correctly, tested it with TE_BEAMPOINTS.

Im not sure if i saw this message functioning

But here try this for lightning.

PHP Code:


			
    engfunc(EngFunc_MessageBegin, MSG_BROADCAST, SVC_TEMPENTITY, {0.0, 0.0, 0.0}, 0)
    write_byte(0) 
    engfunc(EngFunc_WriteCoord, tfOrigin[0]) // Start
    engfunc(EngFunc_WriteCoord, tfOrigin[1])
    engfunc(EngFunc_WriteCoord, tfOrigin[2])
    engfunc(EngFunc_WriteCoord, fOrigin[0]) // End
    engfunc(EngFunc_WriteCoord, fOrigin[1])
    engfunc(EngFunc_WriteCoord, fOrigin[2])
    write_short(g_lightning_sprite) "sprites/lgtning.spr"
    write_byte(1) // framestart 
    write_byte(10) // framerate 
    write_byte(30) // life 
    write_byte(100) // width 
    write_byte(100) // noise 
    write_byte(200) // r, g, b 
    write_byte(200) // r, g, b 
    write_byte(200) // r, g, b 
    write_byte(200) // brightness 
    write_byte(50) //  
    message_end()

I know how I can do it with other TE_ types. I need to know how TE_LIGHTNING specifically works if it even works. I don't need this for a plugin.

Where do you think I got the things in the first post from? I did it exactly as described in both links and it's not working.

Actually i've tested and its working but it invisible, cause when i spawned many beams together and was looking them my fps was dropping down.

Code:


Try the following format i moved sprite model index to 7th param instead of the last.

/**
 *TE_LIGHTNING is TE_BEAMPOINTS with simplified parameters
 *
 * @note
 * write_byte(TE_LIGHTNING)
 * write_coord(startposition.x)
 * write_coord(startposition.y)
 * write_coord(startposition.z)
 * write_coord(endposition.x)
 * write_coord(endposition.y)
 * write_coord(endposition.z)
 * write_short(sprite model index)
 * write_byte(life in 0.1's)
 * write_byte(width in 0.1's)
 * write_byte(amplitude in 0.01's)
 */

I just noticed that if TE_BEAMPOINTS is executed, then TE_LIGHTNING will work using the colors previously set with TE_BEAMPOINTS.

This is definitely a bug or wrong documentation. @Arkshine?

@Natsheh - that didn't work either.

Tried using the same parameters as TE_BEAMPOINTS - no effect also.

It's up to the engine, not AMXX.

But anyway the code that uses TE_LIGHTNING can only be found in one spot in HLSDK and it's commented out in favor of TE_BEAMPOINTS, so maybe it never worked.

Here found a usable in the hlsdk/effects.cpp

PHP Code:


			


void CLightning::Zap( const Vector &vecSrc, const Vector &vecDest )

{

#if 1

    MESSAGE_BEGIN( MSG_BROADCAST, SVC_TEMPENTITY );

        WRITE_BYTE( TE_BEAMPOINTS);

        WRITE_COORD(vecSrc.x);

        WRITE_COORD(vecSrc.y);

        WRITE_COORD(vecSrc.z);

        WRITE_COORD(vecDest.x);

        WRITE_COORD(vecDest.y);

        WRITE_COORD(vecDest.z);

        WRITE_SHORT( m_spriteTexture );

        WRITE_BYTE( m_frameStart ); // framestart

        WRITE_BYTE( (int)pev->framerate); // framerate

        WRITE_BYTE( (int)(m_life*10.0) ); // life

        WRITE_BYTE( m_boltWidth );  // width

        WRITE_BYTE( m_noiseAmplitude );   // noise

        WRITE_BYTE( (int)pev->rendercolor.x );   // r, g, b

        WRITE_BYTE( (int)pev->rendercolor.y );   // r, g, b

        WRITE_BYTE( (int)pev->rendercolor.z );   // r, g, b

        WRITE_BYTE( (int)pev->renderamt );    // brightness

        WRITE_BYTE( m_speed );        // speed

    MESSAGE_END();

#else

    MESSAGE_BEGIN( MSG_BROADCAST, SVC_TEMPENTITY );

        WRITE_BYTE(TE_LIGHTNING);

        WRITE_COORD(vecSrc.x);

        WRITE_COORD(vecSrc.y);

        WRITE_COORD(vecSrc.z);

        WRITE_COORD(vecDest.x);

        WRITE_COORD(vecDest.y);

        WRITE_COORD(vecDest.z);

        WRITE_BYTE(10);

        WRITE_BYTE(50);

        WRITE_BYTE(40);

        WRITE_SHORT(m_spriteTexture);

    MESSAGE_END();

#endif

    DoSparks( vecSrc, vecDest );

}
