Actor-oriented scripting language Mana

Issues, Discussions, Wiki, Doxygen

This scripting language was developed with the aim of developing a character's action using actor model. You can implement the execution engine easily into your computer game program.

What Mana code looks like

{mana:talk.mn} 
actor Mother
{
    int mFlag;
    action initialize
    {
        mFlag = 0;
    }
    action main
    {
        print("Hi");
        request(1, Child::talk);
    }
}
 
actor Child
{
    action update
    {
        int i;
    }
    action talk
    {
        print("Hi");
    }
}
