EDIT2:
Im using this now:

PHP Code:

public fw_EmitSound(ent, channel, const sample[], Float:volume, Float:attn, flags, pitch)
{
    if(equali(sample, "weapons/mine_activate.wav") && pev_valid(ent))
    {
        new Float:flOrigin[3]
        new Float:flVecEnd[3]

        pev(ent, pev_origin, flOrigin)
        flVecEnd[0] = get_pdata_float(ent, m_vecEnd_x, XO_PLAYER)
        flVecEnd[1] = get_pdata_float(ent, m_vecEnd_y, XO_PLAYER)
        flVecEnd[2] = get_pdata_float(ent, m_vecEnd_z, XO_PLAYER)

        new beam
        beam = get_pdata_cbase(ent, 176, XO_PLAYER)

        if(pev_valid(beam))
            RelinkBeam(beam, flVecEnd, flVecEnd, flOrigin)
    }
}

RelinkBeam(const beam, const Float: Origin[3], const Float: startPos[3], const Float: endPos[3])
{
    static Float: mins[3], Float: maxs[3]

    mins[0] = floatmin(startPos[0], endPos[0])
    mins[1] = floatmin(startPos[1], endPos[1])
    mins[2] = floatmin(startPos[2], endPos[2])

    maxs[0] = floatmax(startPos[0], endPos[0])
    maxs[1] = floatmax(startPos[1], endPos[1])
    maxs[2] = floatmax(startPos[2], endPos[2])

    xs_vec_sub(mins, Origin, mins)
    xs_vec_sub(maxs, Origin, maxs)

    set_pev(beam, pev_mins, mins)
    set_pev(beam, pev_maxs, maxs)

    engfunc(EngFunc_SetSize, beam, mins, maxs)
    engfunc(EngFunc_SetOrigin, beam, Origin)
} 


If you found anything that could be optimized, please tell me
Thanks.

I said the whole code, but it's was just the pev_origin, but since you relink after, I guess it's fine.

equal() is enough. You could also just checking some letters. Except that, not really.

[kNowo]

Aha! you missed one thing: TR_vecEndPos
I need to traceline and get_tr2 TR_vecEndPos or else the beam will visually go through brushes/entities

[Arkshine]

Not sure what you mean, 2048 is used only 2 times.

[kNowo]

I am really bad at explaining things.

flVecEnd is 4000.0 units away from the tripmine, so when I relink the beam, it will relink (visually only) starting from the tripmine and go all the way 4000 units away. So, I traceline the endorigin (where it hits something) first, then relink from tripmine to the new endorigin.

[Arkshine]

I don't think I get what you say. The traceline before calculating "vecTmpEnd" uses m_vecEnd offset.
So just recalculating vecTmpEnd, and relinking with this new origin should be enough.
I don't think it's necessary, but you may need to set pev_origin before, as it's what does "SetStartPos".

[kNowo]

I didn't recalculate vecTmpEnd. Maybe that's why the beam was piercing brushes and entities.
