I'm currently planning to port a LG @ Quake Live to TF2...

I made a demo source code

PHP Code:

    if(weapon == iweaponlist[client][WEAPON_LIGHTNING]) {
        float clpos[3], eyepos[3], clang[3], endpos[3], beampos[3];
        
        GetClientAbsOrigin(client, clpos);
        GetClientEyePosition(client, eyepos);
        GetClientEyeAngles(client, clang);
        
        GetEndPosition(endpos, eyepos, clang, LIGHTNING_LENGTH);
        Handle hTrace = TR_TraceRayFilterEx(eyepos, clang, MASK_PLAYERSOLID, RayType_Infinite, TraceRayAllAllow, client);  
        if(TR_DidHit(hTrace)) {
            TR_GetEndPosition(beampos, hTrace);
        }
        
        if(GetVectorDistance(clpos, endpos) < GetVectorDistance(clpos, beampos)) {
            beampos[0] = endpos[0];
            beampos[1] = endpos[1];
            beampos[2] = endpos[2];
        }
        
        clpos[2] += 30.0;
        
        if(GetClientTeam(client) == 2) TE_SetupBeamPoints(clpos, beampos, LaserModel, HaloModel, 0, 66, 0.058, 1.5, 1.5, 3, 0.0, {255, 0, 255, 255}, 0);
        if(GetClientTeam(client) == 3) TE_SetupBeamPoints(clpos, beampos, LaserModel, HaloModel, 0, 66, 0.058, 1.5, 1.5, 3, 0.0, {0, 255, 255, 255}, 0);
        TE_SendToAll();
    }
stock void GetEndPosition(float end[3], float start[3], float angle[3], float distance, bool:negative = false)
{
    float vector[3];
    end[0] = start[0];
    end[1] = start[1];
    end[2] = start[2];

    vector[0] = Cosine(DegToRad(angle[1]));
    vector[1] = Sine(DegToRad(angle[1]));
    vector[2] = Sine(DegToRad(angle[0])) * -1.0;
    NormalizeVector(vector, vector);
    ScaleVector(vector, distance);

    if(negative) ScaleVector(vector, -1.0);
    AddVectors(end, vector, end);
} 


but the beams can't follow the fire speed..

What forwards or functions should I use to fix this problem?

So are you wanting more beams to appear? or are you wanting the older beams to die faster so you only see a single beam?

I wanting the older beams to die faster so I can only see a single beam like

The sixth argument of the TE_SetupBeamPoints function is the life of the drawn effect. You have this set to 0.058, you will want to make this even small to like 0.01, however keep in mind going really low may result in the beam not drawing at all. Also you'd want to call the function more frequently. You can only go as fast as the tick rate of the server so 1.0/128 = 0.0078 or 1.0/64 = 0.015. This also will still probably look choppy and bad, the only way to sustain an effect like that smoothly in the source engine would be to make it into a model and have it attached to the player entity so it rotates with them. However that comes with issues itself as it will still move up and down on the yaw axis really strangely.

I researched more, but sadly the TE_SetupBeamPoints function's maximum life time is limited above 0.05 seconds. which I think I should use another methods.
