Hi again x.x
I got this script from the Castlevania Collaborative Demo, which I used in Silver Night's Crusaders.

Code: 
void target0T(float Time, float Tx, float Ty, float dx, float dy, void Vel, int Flip)
{// Basic Targetting certain coordinate before dashing
// Produced velocity will be required speed to get to target within specified time
// Time = specified time
// Tx = target x coordinate
// Ty = target y coordinate
// dx = x added distance
// dy = y added distance
// Vel = Desired output

    void self = getlocalvar("self");
    int dir = getentityproperty(self, "direction");
    float x = getentityproperty(self, "x");
    float y = getentityproperty(self, "a");
    float Vx;
    float Vy;

    if(Flip == 1){
      if(Tx < x){
        changeentityproperty(self, "direction", 0);
      } else {
        changeentityproperty(self, "direction", 1);
      }
    }

    x = x+dx;
    y = y+dy;
// Calculate velocity for targetting

    Vx = (Tx-x)/Time;
    Vy = (Ty-y)/Time;

    if(Vel == "x"){
      return Vx;
    }
    if(Vel == "y"){
      return Vy;
    }
}

void targetB(float Time, float dx, float dy, int Flip)
{// Targetting opponent before tossing bomb
// Time = specified time
// dx = x added distance
// dy = y added distance
// Flip = flip flag

    void self = getlocalvar("self");
    int dir = getentityproperty(self, "direction");
    float x = getentityproperty(self, "x");
    float y = getentityproperty(self, "a");
    float Vx;

    setlocalvar("T"+self, findtarget(self)); //Get nearest target
    void Target = getlocalvar("T"+self);

    if( Target != NULL()){
      float Tx = getentityproperty(Target, "x");
      float Ty = getentityproperty(Target, "a");
      float C;
      float Sy = y + dy - Ty;

      if (Sy < 0){ //Negative?
        Sy = -Sy; //Invert to positive
      }

      C = 0.5*(x-Tx)*(y+dy-Ty)/(Time+Sy);

      if (dir == 0){ //Is entity facing left?                 
        dx = -dx; //Reverse X direction to match facing
      }

      Vx = target0T(Time, Tx, Ty, dx-C, 0, "x", Flip);

    } else {
      Vx = 0;
    }

    setlocalvar("x"+self, Vx );
    setlocalvar("T"+self, NULL()); //Clears variable
}


void tosser2(void Bomb, float dx, float dy, float Vx, float Vy)
{ // Tossing special bomb with desired speed
   void self = getlocalvar("self");
   void candamage  = getentityproperty(self, "candamage");
   int Direction = getentityproperty(self, "direction");
   void Shot;

   if (Direction == 0){ //Is entity facing left?                 
      Vx = -Vx; //Reverse Vx direction to match facing
   }

   Shot = spawn01(Bomb, dx, dy, 0);
   tossentity(Shot, Vy, Vx);
   changeentityproperty(Shot, "owner", self);
   changeentityproperty(Shot, "candamage", candamage);
   return Shot;
}

void toss2(void Shot, float dx, float dy, float Vy)
{ // Tossing targetted bombs
   void self = getlocalvar("self");
   float Vx = getlocalvar("x"+self);
   int Direction = getentityproperty(self, "direction");

   if (Direction == 0){ //Is entity facing left?                 
      Vx = -Vx; //Reverse Vx direction to match facing
   }

   if( Vx!=NULL() && Vy!=NULL() ){
     tosser2(Shot, dx, dy, Vx, Vy);
   }
}

Is just what I need!
It throws the Bomb in the proper X and Y Axis, but how can I add the Z axis for use it in a Beat'em up?

I already tried to add the Z axis like this and the game "crashes" or I'm missing something?:
Code: 
void target0T(float Time, float Tx, float Ty, float dx, float dy, float dz, void Vel, int Flip)
{// Basic Targetting certain coordinate before dashing
// Produced velocity will be required speed to get to target within specified time
// Time = specified time
// Tx = target x coordinate
// Ty = target y coordinate
// dx = x added distance
// dy = y added distance
// Vel = Desired output

    void self = getlocalvar("self");
    int dir = getentityproperty(self, "direction");
    float x = getentityproperty(self, "x");
    float y = getentityproperty(self, "a");
    float z = getentityproperty(self, "z");
    float Vx;
    float Vy;
    float Vz;

    if(Flip == 1){
      if(Tx < x){
        changeentityproperty(self, "direction", 0);
      } else {
        changeentityproperty(self, "direction", 1);
      }
    }

    x = x+dx;
    y = y+dy;
    z = y+dz;
// Calculate velocity for targetting

    Vx = (Tx-x)/Time;
    Vy = (Ty-y)/Time;
    Vz = (Tz-z)/Time;

    if(Vel == "x"){
      return Vx;
    }
    if(Vel == "y"){
      return Vy;
    }
    if(Vel == "z"){
      return Vz;
    }
}

void targetB(float Time, float dx, float dy, float dz, int Flip)
{// Targetting opponent before tossing bomb
// Time = specified time
// dx = x added distance
// dy = y added distance
// Flip = flip flag

    void self = getlocalvar("self");
    int dir = getentityproperty(self, "direction");
    float x = getentityproperty(self, "x");
    float y = getentityproperty(self, "a");
    float z = getentityproperty(self, "z");
    float Vx;

    setlocalvar("T"+self, findtarget(self)); //Get nearest target
    void Target = getlocalvar("T"+self);

    if( Target != NULL()){
      float Tx = getentityproperty(Target, "x");
      float Ty = getentityproperty(Target, "a");
      float Tz = getentityproperty(Target, "z");
      float C;
      float Sy = y + dy - Ty;

      if (Sy < 0){ //Negative?
        Sy = -Sy; //Invert to positive
      }

      C = 0.5*(x-Tx)*(y+dy-Ty)/(Time+Sy);

      if (dir == 0){ //Is entity facing left?                  
        dx = -dx; //Reverse X direction to match facing
      }

      Vx = target0T(Time, Tx, Ty, Tz, dx-C, 0, dz, "x", Flip);

    } else {
      Vx = 0;
    }

    setlocalvar("x"+self, Vx );
    setlocalvar("T"+self, NULL()); //Clears variable
}

void tosser2(void Bomb, float dx, float dy, float dz, float Vx, float Vy, float Vz)
{ // Tossing special bomb with desired speed
   void self = getlocalvar("self");
   void candamage  = getentityproperty(self, "candamage");
   int Direction = getentityproperty(self, "direction");
   void Shot;

   if (Direction == 0){ //Is entity facing left?                 
      Vx = -Vx; //Reverse Vx direction to match facing
   }

   Shot = spawn01(Bomb, dx, dy, dz);
   tossentity(Shot, Vy, Vx, Vz);
   changeentityproperty(Shot, "owner", self);
   changeentityproperty(Shot, "candamage", candamage);
   return Shot;
}

void toss2(void Shot, float dx, float dy, float dz, float Vy)
{ // Tossing targetted bombs
   void self = getlocalvar("self");
   float Vx = getlocalvar("x"+self);
   float Vz = getlocalvar("z"+self);
   int Direction = getentityproperty(self, "direction");

   if (Direction == 0){ //Is entity facing left?                  
      Vx = -Vx; //Reverse Vx direction to match facing
   }

   if( Vx!=NULL() && Vy!=NULL() && Vz!=NULL() ){
     tosser2(Shot, dx, dy, dz, Vx, Vy, Vz);
   }
}

The log says that Tz is missing and that's exactly what's missing in your target0T function.
Though even if your scripts are not crashing, they are missing Vz calculation.

If you want latest version of 3D bomb tossing scripts, you should get it from Bird Bunch. One of the bosses there tosses bombs toward birds. Although the first throw is buggy for some reason, the next throws work fine.

Thanks again Bloodbane :D.
Just two questions, maybe I have to create a new topic for this, but it's posible to use Scripts on "Scene" type Stages?
For example:
Code: 
file    data/levels/stage1.txt
next
file    data/levels/stage2.txt
scene    data/scenes/cutscene.txt <--- USE SCRIPTS HERE
next
file    data/levels/stage3.txt
next
file    data/levels/stage4.txt

It's also posible to use the "INTRO.TXT" file as an stage with a predefined Player?

Thanks for the answer :D.

The only way I know is by using either update.c or updated.c . That's how I made scripted Instruction pages in my latest games including Bird Bunch.

I think not.
