Good working Mauzen !!
I am creating a system of zombies, advise the use of RNPC !!

Kill NPC

pawn Code:

// top of gm
new tirosLevados[MAX_PLAYERS];

// onplayer update
static targetplayer,  Keys,ud,lr;
GetPlayerKeys(playerid,Keys,ud,lr);
targetplayer = GetPlayerTargetPlayer(playerid);

if(targetplayer != INVALID_PLAYER_ID && Keys == KEY_FIRE || Keys == 132)
{
    if(IsPlayerNPC(targetplayer)) {
        tirosLevados[targetplayer]++;
        SetPVarInt(playerid, "timesTick", GetTickCount());
        if(tirosLevados[targetplayer] > 20) { // 20 shoots +-
            SpawnPlayer(targetplayer);
            OnPlayerDeath(targetplayer, playerid, GetPlayerWeapon(playerid));
            tirosLevados[targetplayer] = 0;
          }
    }
}

Follow

pawn Code:

CHK_RowMoviment(n, moviment) {

    if(moviment > rowNPCMove[n]) {
        return false;
    }
    
    static
        rowSTR[3][32];

    format(rowSTR[0], 32, "rowNPC%dX", moviment);
    format(rowSTR[1], 32, "rowNPC%dY", moviment);
    format(rowSTR[2], 32, "rowNPC%dZ", moviment);

    return IsPlayerInRangeOfPoint(n, 1.5, GetPVarFloat(n, rowSTR[0]),GetPVarFloat(n, rowSTR[1]),GetPVarFloat(n, rowSTR[2]));
}

EXE_RowMoviment(n) {

    if(!rowNPCMove[n] || execROWMoviment[n] > (rowNPCMove[n] - 1))  {
        return false;
    }

    if(execROWMoviment[n]) {
        if(!CHK_RowMoviment(n, execROWMoviment[n]-1)) {
            return false;
        }
    }

    
    static
        rowSTR[4][32];


    if(execROWMoviment[n] > 1) {
        for(new i = execROWMoviment[n]-1; i > -1; i--) {
            format(rowSTR[0], 32, "rowNPC%dX", i);
            format(rowSTR[1], 32, "rowNPC%dY", i);
            format(rowSTR[2], 32, "rowNPC%dZ", i);
            format(rowSTR[3], 32, "rowNPC%dS", i);

            DeletePVar(n,rowSTR[0]);
            DeletePVar(n,rowSTR[1]);
            DeletePVar(n,rowSTR[2]);
            DeletePVar(n,rowSTR[3]);
        }
    }
    
    format(rowSTR[0], 32, "rowNPC%dX", execROWMoviment[n]);
    format(rowSTR[1], 32, "rowNPC%dY", execROWMoviment[n]);
    format(rowSTR[2], 32, "rowNPC%dZ", execROWMoviment[n]);
    format(rowSTR[3], 32, "rowNPC%dS", execROWMoviment[n]);
    
    MoveRNPC(n, GetPVarFloat(n, rowSTR[0]),GetPVarFloat(n, rowSTR[1]),GetPVarFloat(n, rowSTR[2]),GetPVarFloat(n, rowSTR[3]));

    return execROWMoviment[n]++;
}

ADD_RowMoviment(n, Float:x, Float:y, Float:z, Float:s) {

    static str[32];

    format(str, 32, "rowNPC%dX", rowNPCMove[n]);
    SetPVarFloat(n, str, x);
    
    format(str, 32, "rowNPC%dY", rowNPCMove[n]);
    SetPVarFloat(n, str, y);
    
    format(str, 32, "rowNPC%dZ", rowNPCMove[n]);
    SetPVarFloat(n, str, z);
    
    format(str, 32, "rowNPC%dS", rowNPCMove[n]);
    SetPVarFloat(n, str, s);

    return rowNPCMove[n]++;
}

Now use:

pawn Code:

ADD_RowMoviment(npcid, x-0.1, y-0.1, z,0.006);
// MoveRNPC(npcid, x-0.1, y-0.1, z,0.006);
EXE_RowMoviment(npcid);

pawn Code:

new execROWMoviment[MAX_PLAYERS];
new rowNPCMove[MAX_PLAYERS];

This follows exactly where the player walks. It can also be optimized ..

- So the NPC does not fly on the wall, or walk inside them or fly into holes
