Sharing variables through multiple functions

The current way to pass things around is to utilize the dynamic property of the actor. Since actors can be cloned during runtime there needs to be a way to give each actor the ability to customize itself as needed. You could also define a global variable in the top of your script file like: int $globalValue = 0;. The dollar signs will make sure there's no naming collisions.

typedef struct $_MyVars
{
    int someValue;
        // Put more variables in here if you like.
} $MyVars;

void $Start(Actor *self)
{
        // Have to allocate space for this struct on the heap.
        $MyVars *myVars = ($MyVars *)malloc(sizeof($MyVars));

        myVars->someValue = 2;

        self->dynamic = myVars;
}

void $Update(Actor *self)
{
     $MyVars *myVars = ($MyVars *)self->dynamic;

     if (myVars != NULL)
     {
                int test = 1 + myVars->someValue;
     }
}

If the actor get destroyed the dynamic data will be released. I may find better ways in the future to allow actors to "talk" to each other and share variables within themselves. There is a notify method that lets you send messages to other actors.
