Trouble with Blocking System

I created a blocking system for holding the back key with animation script. Plus, there are two scripts that correlate the blocking. One is for making the opponent block and the other is for resulting the unblocking afterwards.

C: 
void makeOpponentBlock(){
//void opponent = whatever method you use to get opponent;
//int opponentIndex = get your opponent player index;
//function variable name = script function
    void self = getlocalvar("self");
    //void opponent = findtarget(self);
    void opponent = getentityproperty(self, "opponent");
    int P1 = getplayerproperty(0, "entity");
    int P2 = getplayerproperty(1, "entity");
    //void opp1 = findtarget(P1);
    //void opp2 = findtarget(P2);

    void opp1 = getentityproperty(P1, "opponent");
    void opp2 = getentityproperty(P2, "opponent");

    int opponentIndex = getentityproperty(opponent, "playerindex"); // in the future, you should check that opponent is indeed of type player
    int iDir1 = getentityproperty(opp1, "direction");
    int iDir2 = getentityproperty(opp2, "direction");
    int iDir = getentityproperty(opponent, "direction");
    int iLeft = playerkeys(opponentIndex, 0, "moveleft");
    int iLeft1 = playerkeys(opp1, 0, "moveleft");
    int iLeft2 = playerkeys(opp2, 0, "moveleft");
    int iRight = playerkeys(opponentIndex, 0, "moveright");
    int iRight1 = playerkeys(opp1, 0, "moveright");
    int iRight2 = playerkeys(opp2, 0, "moveright");
    void vAniID = getentityproperty(opponent, "animationid");
    void vAniID1 = getentityproperty(opp1, "animationid");
    void vAniID2 = getentityproperty(opp2, "animationid");
    int frame = getentityproperty(opponent, "animpos");
    int frame1 = getentityproperty(opp1, "animpos");
    int frame2 = getentityproperty(opp2, "animpos");
    int type;
    int attacking = getentityproperty(opponent, "attacking");
    float x = getentityproperty(self, "x");
    float z = getentityproperty(self, "z");

   
    int i = 0;
    void opp = NULL();
   
    for(i = 0; i < openborvariant("count_entities"); ++i){
        void entity = getentity(i);
       
        if(getentityproperty(entity, "exists")){
            void type = getentityproperty(entity, "type");
            if(type == openborconstant("TYPE_ENEMY")){
                opp = entity;
                break;
            }
        }
    }
   
    if(getentityproperty(opp, "exists") && opp != NULL()){
        int attacking = getentityproperty(opp, "attacking");
        void opp = findtarget(opponent);
       
        float Tx = getentityproperty(opp, "x");
        float Tz = getentityproperty(opp, "z");
        float Disx = Tx - x;
        float Disz = Tz - z;
       
    //    if(Disz < 0){
    //        Disz = -Disz;
    //    }
   
        //if(iDir = 0){

                if( /*Disx >= 0 && Disx <= 30 && */ iDir == 1 && iLeft) // Target within range on right facing?
                {
                    performattack(opponent, openborconstant("ANI_FOLLOW4"));
                    tossentity(opponent, 0, 0, 0);

        //}
    }
   
    log("\nopponentIndex" + "\nopponent");
   
}

C: 
void makeOpponentUnblock(){

    void self = getlocalvar("self");
    void opponent = findtarget(self);
    int opponentIndex = getentityproperty(opponent, "playerindex");

Here are the blocking animations.
blocking-animations-png.5528


I copied the guard script under anim pain from the Map demo but modified it for holding the back key. But when I hold back while getting hit with pain anim, the health bar doesn't reduce.
anim-pain-on-blocking-mechanics-png.5525


My main problem with the blocking system is that when you hold the back key for performing it, you have to get hit first. That's when you're able to perform blocking animation after.

I use findtarget and it seems to work, but it crashes when you try to use block when a projectile reaches you. That's why I started using the opponent property instead of findtarget.

Code: 
    void opp1 = findtarget(P1);
    void opp2 = findtarget(P2);

Player projectile:

This one is for projectile and it works like you play in any SF game which you are limited to unleash a projectile once until it hits or misses its target.
C: 
void spawnAndThrow(void projName, float xPos, float zPos, float yPos, float fX, float fZ, float fY){
    
    void proj = spawn01(projName, xPos, yPos, zPos);
    throwProj(proj, fX, fZ, fY); 
}

void throwProj(void proj, float fX, float fZ, float fY){

    void self = getlocalvar("self");
    void target = getentityproperty(self, "opponent");
    void parent = getentityproperty(self, "parent");
    void index = getentityproperty(self, "playerindex");

    if(fX == -77) fX = getlocalvar("x"+self);
    else if(fX == -33) fX = getlocalvar("x"+self) / 2;
    else if (getentityproperty(proj, "direction")==0){
        fX = -fX;
    }
    
    if(fZ == -77) fZ = getlocalvar("z"+self);
    else if(fZ == -33) fZ = getlocalvar("z"+self) / 2;
    
    
    changeentityproperty(proj, "velocity", fX, fZ, fY);

}

How can I allow a player to make a firmly automatic block without having to get hit first? The player does not block every time its opponent poses any attacks.

I copied the guard script under anim pain from the Map demo but modified it for holding the back key

Which guard script? I've checked it and Fighter is the only one with 50% dodge script in his damagescript.

Anyways, I've made quick read of this thread and I really don't understand why you would need the attacker to order the opponent to block.
I always consider blocking in Fighting games as "if opponent is attacking when player is moving back, do block instead". IOW you should be checking if opponent is attacking you or not to decide to block or not when moving backward. I guess range check is also needed here.

Indeed. That's the Fighter's guard damagescript (Dodger.c). I used the Fighter's damage script as a reference for the pain animation.

I copied this one from the Map demo.
C: 
anim pain1
@script
    if(frame == 0){
      void self = getlocalvar("self");
      int Dodge = getentityvar(self, 8);

      if(Dodge == 1){
        changeentityproperty(self, "animation", openborconstant("ANI_FREESPECIAL5"));
      }
    }

This is my damage script I have for the player which I renamed it to guard.c.
C: 
void main(){
    void self = getlocalvar("self");
    int index = getentityproperty(self, "playerindex");
    int left = playerkeys(index, 0, "moveleft");
    int right = playerkeys(index, 0, "moveright");
    int y = getentityproperty(self, "a");
    int direction = getentityproperty(self, "direction");
    int HP = getentityproperty(self, "health");
    void aniID = getentityproperty(self, "animationid");
    void target = getentityproperty(self, "opponent");
    void tAniID = getentityproperty(target, "animationid");
    int damage = getlocalvar("damage");
    int r = rand()%30;
    int lastHitY = openborvariant("lasthity");
    //void Block = loadsample("data/sounds/block.wav");
    
    if((lastHitY > 52) && ((direction == 1 && left) || (direction == 0 && right))){
//        if(r > 0){
            setentityvar(self, "guard", 1);
            changeentityproperty(self, "health", HP + damage);
        }else if((lastHitY <= 52) && ((direction == 1 && left) || (direction == 0 && right))){
            setentityvar(self, "guard", NULL());
//        }
    }
}

While you block, the player plays pain animation instead of block animation after the projectile hits you. However, the player's lifebar doesn't deplete. That's because I'm trying to not let the health bar reduce after/while blocking. Maybe I would like the health bar to reduce slightly when the opponent performs with any special move.

Thanks, Bloodbane! 😁 Does that mean I'm gonna have to use checkrange() for range checks between a player and the opponent? Do you have an example of how checkrange is used? Not only am I struggling with the player blocking in PvP matches, but also one player mode against any CPU opponents. I do want the players to block as you said. Block when the opponent does attack. In closed range or open (far) range?

checkrange(entity, target, int animid)

  • Check if the given target is in range. Range, rangez, rangea of the specified animation will be used for checking.
  • entity - animation owner. Must be a valid entity handle. Required.
  • target - must be a valid entity handle. Required.
  • animid - animation id. Optional. If it is not given, current animation will be used.
