Projectile's palette according the parent's one

16-bit Fighter · Jun 11, 2023

In my mod a char uses the projectile command and I'd like the projectile's palette to be according the char's one.

I created an onspawnscript for the projectile's entity but nothing happens:

C:

void main ()

{

    void self = getlocalvar("self");

    void parent = getentityproperty(self, "parent");

    int PMap = getentityproperty(parent, "map");

    if(parent!=NULL()){

    changeentityproperty(self, "map", PMap);

    }

}

Any idea about the problem please?

Probably your projectile doesn't knows who is the parent.
projectiles throw by native means knows who is the parent, but the ones by script doesn't. You need to feed it.

Thanks! I'm not familiar with parents so could you tell me how to make the connection between the two entities please?

How are you spawning your projectile?

I was wrong, sorry, I actually use the command toss, not projectile:

C:

void toss(void Bomb, float dx, float dy, float dz)
{ // Tossing bomb
   void self = getlocalvar("self");
   int Direction = getentityproperty(self, "direction");
   int x = getentityproperty(self, "x");
   int y = getentityproperty(self, "a");
   int z = getentityproperty(self, "z");

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

   projectile(Bomb, x+dx, z+dz, y+dy, Direction, 0, 1, 0);
}

This is how I do it when spawning a projectile, but both projectile and parent need to have their colors in the same color table. I have not tried it with separate color tables for each of those two, but this is all I know.

Solved - Item On Death Palette

Hi so I asked about how to make a 'dead' animation that loops a while ago and my uneducated hunch was correct, you do the ol' nodieblink 2 and spawn an object. But what if you want it to match the palette of the enemy? All I can think of is writing a script that gets what palette the enemy is...

www.chronocrash.com

Remove that if condition from it, so you let that changeentityproperty function be outside along with those.

BTW the script looks similar to what I did weeks ago. I can spawn it with spawnframe or spawning scripts.

EDIT:

C:

void main ()
{
    void self = getlocalvar("self");
    void parent = getentityproperty(self, "parent");
    int PMap = getentityproperty(parent, "map");

    changeentityproperty(self, "map", PMap);
}

O Ilusionista · Jun 11, 2023

This SHOULD work - its how I use on my scripts:

C-like:

void toss(void Bomb, float dx, float dy, float dz)
{ // Tossing bomb
   void self = getlocalvar("self");
   int Direction = getentityproperty(self, "direction");
   int x = getentityproperty(self, "x");
   int y = getentityproperty(self, "a");
   int z = getentityproperty(self, "z");

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

   projectile(Bomb, x+dx, z+dz, y+dy, Direction, 0, 1, 0);
   changeentityproperty(Bomb,"parent",self); // <--- ADDED
}

Thanks guys but it doesn't work yet.

There's no change with this script.

When the char performs the function the program shuts down. Here is the log:

O Ilusionista · Jun 12, 2023

weird, try changing the order like this:

C-like:

void toss(void Bomb, float dx, float dy, float dz)
{ // Tossing bomb
   void self = getlocalvar("self");
   int Direction = getentityproperty(self, "direction");
   int x = getentityproperty(self, "x");
   int y = getentityproperty(self, "a");
   int z = getentityproperty(self, "z");

   if (Direction == 0){ //Is entity facing left?               
      dx = -dx; //Reverse X direction to match facing
   }
   changeentityproperty(Bomb,"parent",self); // <--- ADDED
   projectile(Bomb, x+dx, z+dz, y+dy, Direction, 0, 1, 0);
}

We can even add a safe check

C-like:

void toss(void Bomb, float dx, float dy, float dz)
{ // Tossing bomb
   void self = getlocalvar("self");
   int Direction = getentityproperty(self, "direction");
   int x = getentityproperty(self, "x");
   int y = getentityproperty(self, "a");
   int z = getentityproperty(self, "z");

   if (Direction == 0){ //Is entity facing left?               
      dx = -dx; //Reverse X direction to match facing
   }
if (vShot){// safe check
   changeentityproperty(Bomb,"parent",self); // <--- ADDED
}
   projectile(Bomb, x+dx, z+dz, y+dy, Direction, 0, 1, 0);
}

I have two versions of this script, and the second one has this parent part:

C-like:

void toss(void Bomb, float dx, float dy, float dz)
{ // Tossing bomb
   void self = getlocalvar("self");
   int Direction = getentityproperty(self, "direction");
   int x = getentityproperty(self, "x");
   int y = getentityproperty(self, "a");
   int z = getentityproperty(self, "z");


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


   projectile(Bomb, x+dx, z+dz, y+dy, Direction, 0, 1, 0);
}


void toss2(void Shot, float dx, float dy, float dz, float Vx, float Vy, float Vz)
{ // Shooting projectile
   void self = getlocalvar("self");
   int Direction = getentityproperty(self, "direction");
   int x = getentityproperty(self, "x");
   int y = getentityproperty(self, "a");
   int z = getentityproperty(self, "z");
   void vShot;


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


    vShot = projectile(Shot, x+dx, z+dz, y+dy, Direction, 0, 1, 0);
    if (vShot){// safe check
    changeentityproperty(vShot, "velocity", Vx, Vz, Vy);
  
   return vShot;
 }
}

I'm stuck, nothing changes. And with the your script below, @O Ilusionista , OB shuts down from loading.

C:

    [CODE=clike]void toss(void Bomb, float dx, float dy, float dz)

    { // Tossing bomb

       void self = getlocalvar("self");

       int Direction = getentityproperty(self, "direction");

       int x = getentityproperty(self, "x");

       int y = getentityproperty(self, "a");

       int z = getentityproperty(self, "z");


       if (Direction == 0){ //Is entity facing left?           

          dx = -dx; //Reverse X direction to match facing

       }

    if (vShot){// safe check

       changeentityproperty(Bomb,"parent",self); // <--- ADDED

    }

       projectile(Bomb, x+dx, z+dz, y+dy, Direction, 0, 1, 0);

    }

Here is the log:

Ah if you are using the second code, change the (vShot) to (Bomb)

Tested what you suggested but when the function is activated OB shuts down.

Its pretty much what I posted above

@16-bit Fighter here, I've tested it and it works - I made a different function to not clash with your previous function:

C-like:

void tossParent(void Bomb, float dx, float dy, float dz)
{ // Toss bomb with parent
   void self = getlocalvar("self");
   int Direction = getentityproperty(self, "direction");
   int x = getentityproperty(self, "x");
   int y = getentityproperty(self, "a");
   int z = getentityproperty(self, "z");
   void vShot;


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


    vShot = projectile(Bomb, x+dx, z+dz, y+dy, Direction, 0, 1, 0);
    if (vShot){// safe check
    changeentityproperty(vShot,"parent",self);
 
   return vShot;
 }
}

The usage is the same, just keep in mind the function name is tossParent

Probably, the issue was the lack of "return".

Thanks but it still doesn't work. I don't know where I make an error. I renamed the tossParent function in toss in exchange for the previous toss function. The player can perform the move but the projectile is with the palette 0 no matter the number of char's palette.
What should I check according to you?

Edit: Well, if I use my the function in the anim itself it works but the onspawnscript function doesn't. Strange...

@16-bit Fighter
The methods @O Ilusionista and @pudu posted should work, I use the same in some SORX scripts. But as an alternative, you can define the spawn map directly without getting a parent's map, I use this method too.

C:

void toss(void Bomb, float dx, float dy, float dz)
{ // Tossing bomb
    void self = getlocalvar("self");
    int Direction = getentityproperty(self, "direction");
    int x = getentityproperty(self, "x");
    int y = getentityproperty(self, "a");
    int z = getentityproperty(self, "z");
    int map = getentityproperty(self, "map");

    if (Direction == 0){ //Is entity facing left?                 
        dx = -dx; //Reverse X direction to match facing
    }
    projectile(Bomb, x+dx, z+dz, y+dy, Direction, 0, 1, 0);
    changeentityproperty(Bomb, "map", map);
}

16-bit Fighter · Jun 22, 2023

I'd really prefer the onswpanscript to work instead of my current solution. Because it makes more sense and my script in the animation itself works only from the second frame, which makes me have to make the first frame having delay 1 if I want the problem not to be noticed.

With the onspawnscript (not working):

C:

void main ()

{

    void self = getlocalvar("self");

    void parent = getentityproperty(self, "parent");

        int PMap = getentityproperty(parent, "map");

    if(parent!=NULL()){

    changeentityproperty(self, "map", PMap);

    }

}

With the animation (working but just form the 2nd frame):

C:

anim idle

    delay    7

    offset    31 31

    loop    1 1 // 1 1

    followanim    1

    followcond    1

    attack3    3 2 59 62 18 0 0 0 8 17 //

    forcedirection    -1

    @script

    void self = getlocalvar("self");

    void parent = getentityproperty(self, "parent");

        int PMap = getentityproperty(parent, "map");

    if(parent!=NULL()){

    changeentityproperty(self, "map", PMap);

    }

    @end_script

    @cmd    antiwallCollide 10 "ANI_FOLLOW2"

    frame    data/chars/andy'/hishoken01.png

    delay    7

    @cmd    antiwallCollide 10 "ANI_FOLLOW2"

    frame    data/chars/andy'/hishoken02.png

    @cmd    antiwallCollide 10 "ANI_FOLLOW2"

    frame    data/chars/andy'/hishoken01.png

    @cmd    antiwallCollide 10 "ANI_FOLLOW2"

    frame    data/chars/andy'/hishoken02.png

If I use the condition below instead of the one above, it doesn't work:

C:

if(frame == 0 && parent!=NULL())

Is there someone who sees an error?

Did the suggestion I posted changing the map inside the @cmd toss work? Currently I'm using it on all projectiles in SORX and working from the first frame.
