script for a fighting system like Street Fighter

[StrikerX]

Hi, I'm trying to create a script for a fighting system like Street Fighter, 1v1 but with Z-axis movement working. So, when holding "moveleft," the player move left and it doesn't turn around or turn player back to the enemy. The character always faces where the opponent is. This way, when holding back, the player uses the backwalk and stays facing the opponent. It worked, but the Z buttons don't function in this backwalk.

The moveup and movedown buttons are simply ignored in the backwalk animations.

I tried replacing the backwalk with a Follow22, but the result is the same. What is wrong with my script?

@script
    void self = getlocalvar("self");
    int plyr  = getentityproperty(self,"playerindex");
    void target = findtarget(self);

    if(!target) return;

    float x  = getentityproperty(self,"x");
    float Tx = getentityproperty(target,"x");
    int dir  = (Tx < x) ? 0 : 1;

    changeentityproperty(self,"direction",dir);

    // BACK
    if( (dir==1 && playerkeys(plyr,0,"moveleft")) ||
        (dir==0 && playerkeys(plyr,0,"moveright")) )
    {
        performattack(self, openborconstant("ANI_backwalk"));
    }

    // FORWARD
    else if( (dir==1 && playerkeys(plyr,0,"moveright")) ||
             (dir==0 && playerkeys(plyr,0,"moveleft")) )

Solved. AI showed me the correct code; now the player always faces the enemy, even if player moveleft, moveright, movedown or moveup. Reminded me now God of War.

    if(!target) return;

    int dir  = (Tx < x) ? 0 : 1;

    float vx = 0;

        if(playerkeys(plyr,0,"moveup"))   vz = -zspeed;
        if(playerkeys(plyr,0,"movedown")) vz =  zspeed;

        // ORDEM CORRETA: X , Z , Y

That might work, but you're fighting the engine. You would be much better off using the native force direction in a think event script. Just calculate which side the nearest opponent is on, set forcedirection property accordingly, and let OpenBOR do the rest. It will be smoother, get all that ugly inline script out of your model sheet, and let you use the engine's native Backwalk animations without any fuss.
