Hello, is there something wrong with this function that returns distance between entity and ground. If the entity "is not on ground", it returns normal value. Now if the entity is on or under of the ground, it returns 9999.0. Any ideas?

Float:DistanceToGround(this)
{
    static Float:flFraction, Float:vecStart[3], Float:vecEnd[3];

    entity_get_vector(this, EV_VEC_origin, vecStart);
    xs_vec_set(vecEnd, vecStart[0], vecStart[1], vecStart[2] - 9999.0);

    //engfunc(EngFunc_TraceLine, vecStart, vecEnd, IGNORE_MONSTERS, this, 0);
    engfunc(EngFunc_TraceHull, vecStart, vecEnd, IGNORE_MONSTERS, HULL_HEAD, this, 0);

    //global_get(glb_trace_fraction, flFraction);

    get_tr2(0, TR_flFraction, flFraction);
    
    return flFraction * 9999.0;
}

Why not using fm_distance_to_floor from fakemeta_util ?

Same issue, but now returning 7848.52.

dont return/stamp if its equal to that number, cuz you only need distance above the ground ?

Well, for my purpose looks working fine, but maybe it won't work at another situations. I will keep the post opened, case anyone have other suggestion.

Float:DistanceToGround(this)
{
    static Float:flFraction, Float:vecStart[3], Float:vecEnd[3];

    entity_get_vector(this, EV_VEC_origin, vecStart);
    xs_vec_set(vecEnd, vecStart[0], vecStart[1], vecStart[2] - 9999.0);

    //engfunc(EngFunc_TraceLine, vecStart, vecEnd, IGNORE_MONSTERS, this, 0);
    engfunc(EngFunc_TraceHull, vecStart, vecEnd, IGNORE_MONSTERS, HULL_HEAD, this, 0);

    //global_get(glb_trace_fraction, flFraction);

    get_tr2(0, TR_flFraction, flFraction);
    
    if (flFraction == 1.0)
        return 0.0;

    //flFraction *= 9999.0;

    return flFraction * 9999.0;
}

Just check if the player is on ground and return 0.

[CrazY.]

The purpose is not check if player is on the ground. Basically, the entity is set in player's aim origin, but must keep on ground, that means, x/y based on player's view angle origin and z based on ground. So what I did was subtract distance from vecOrigin[2]. Anyway, the code still is not working properly.

Why not use TraceLine & get vecEndPos?

[CrazY.]

Because if player aim at the sky or wall, the entity don't keep on ground, on the contrary, it floats. Or you mean traceline in DistanceToGround function?

Why we need player aim, just get origin and subtract from 3rd dimension maximum value to get endorigin for traceline?
