I'm trying to use a struct to keep track of all of the player's stats, but the only thing that works is to use an array.
This is fairly clunky and unnecessary, as I only have one.
How can I do this?

Code: Select all

typedef struct playerStructAttributes {
    int energy;
    int health;
              }playerAttributes;

playerAttributes playerstats[1];

//Called from the view when it's created
void setattributes() {
    playerstats[0].energy = 0;
    playerstats[0].health = 100;
}

//Called from an actor at various points
void addenergy () {
    playerstats[0].energy += 5;
}


I'm not sure why it's breaking for you, but in this case it might be better just to use an "anonymous struct," where you don't name a struct data type, but create a variable using it without any of that.

Code: Select all

struct {
    int energy;
    int health;
} playerstats;


And then you can use the "playerstats" variable right away like "playerstats.health".

What do you mean when you say that the only thing that works is to use an array?
I modified your code to test it without an array and the code works perfectly fine for me.

Code: Select all

typedef struct playerStructAttributes
{
    int energy;
    int health;
}playerAttributes;

playerAttributes playerstats;

//Called from the view when it's created
void setattributes()
{
    playerstats.energy = 0;
    playerstats.health = 100;
}

//Called from an actor at various points
void addenergy()
{
    playerstats.energy += 5;
}

It works now; I was probably just making some stupid mistake.
Thanks for the suggestion DarkParadox, though.

Another problem:
This code throws the error: Error line 62: unexpected declaration sprintf

Code: Select all

void createenemy(int type) {
    Actor * view = getclone("view");
    char tempstring[256];
    sprintf(tempstring, "enemy%i", type);
    Actor * enemy = CreateActor("enemy", tempstring, "(none)", "(none)", view->x - 200, view->y - 200, true); //Line 62
       }

Code: Select all

void createenemy(int type) {
    Actor * c_view = getclone("c_view");
    char tempstring[256];
    Actor * enemy = CreateActor("enemy", tempstring, "(none)", "(none)", c_view->x - 200, c_view->y - 200, true);
    sprintf(tempstring, "enemy%i", type);
       }

This line:

Code: Select all

Actor * enemy = CreateActor("enemy", tempstring, "(none)", "(none)", view->x - 200, view->y - 200, true);

is not safe because enemy will point to the created actor. you can allocate it though and free when function ends. Idk were are you about to use the code tho.

The problem is that you can't have that sprintf() call there between the variable declarations.
You have to do it so that you define Actor ' enemy there, and then call sprintf, and after that set enemy equal to CreateActor()
