Github repository, made some minor improvements

[zort]

There were some changes I wanted to make. To share them, I put them in a github repository: https://github.com/zort/lf2-ai-scriptengine Can consider this zort's fork until Silva or SomeoneElse give their approval I guess.

Here's the list of changes:

• Upgraded to Angelscript 2.32.0 (mainly for array.sort() that takes comparator function)
  
• Added Object.vrests (was split into int vrest and char unkwn8[396])
  
• Added global elapsed_time (number of TUs since start of match)
  
• Added vector3 type
  
• Copy more fields from Object to Info (the self and target globals):
  • x_real, y_real, z_real
    
  • vector3 position, velocity
    
  • wait_counter (also fixed offset in Object, previously was 4 bytes off, as was ctimer and ccatcher)
    
  • weapon_holder
    
• Added function setEnemy(int) for use in ego() for setting the enemy that the AI targets when you return 0 from ego() (in fact I initially thought this was what loadTarget did) - though it's only as useful as ego() is, which at the moment is not very useful because it's limited to basic Template AI
  
• Fixed signatures of Info constructors, now you can construct an Info via Info(object_num) (useful because unlike Object, Info stores its own num and other goodies)
  
• Made Info fields changeable (non-const), now you can do like obj.frame = obj.data.frames[obj.frame].next to simulate obj in the next TU
  
• Added enum ItrKinds:

     KIND_NORMAL = 0,
  KIND_CATCH_DOP = 1,
  KIND_PICK_WEAPON = 2,
  KIND_CATCH = 3,
  KIND_THROWN = 4,
  KIND_WEAPON = 5,
  KIND_FINISH_HIM = 6,
  KIND_ROWING_PICK = 7,
     KIND_HEAL = 8,
  KIND_SHIELD = 9,
  KIND_FLUTE = 10,
  KIND_FLUTE_2 = 11,
  KIND_OBSTACLE = 14,
  KIND_WHIRLWIND_LIFT = 15,
  KIND_WHIRLWIND_FREEZE = 16,

Here's the DLLs: debug, release

Everything is backwards compatible of course, or at least it should be.

To show some of the new features, here's a script that always targets the nearest enemy (gets very confused):

AI-Code: double distance_to(const Info& other) {    return (self.position - other.position).length(); }   bool closer(const Info& a, const Info& b) {    return distance_to(a) < distance_to(b); }   array<const Info@> getEnemyObjects() {    array<const Info@> ret = {};    for (int i = 0; i < 400; i++) {        // exists        if (!game.exists[i])            continue;        // not us        if (i == self.num)            continue;        // is enemy        if (game.objects[i].team == self.team)            continue;        // is alive        if (game.objects[i].hp <= 0)            continue;          ret.insertLast(Info(i));    }      return ret; }   array<const Info@> getEnemies() {    array<const Info@> enemyObjects = getEnemyObjects();    array<const Info@> ret = {};    for (uint i = 0; i < enemyObjects.length(); i++) {        // is human        if (enemyObjects[i].type != 0)            continue;          ret.insertLast(enemyObjects[i]);    }      return ret; }   array<const Info@> attackableEnemies() {    array<const Info@> enemies = getEnemies();    array<const Info@> ret = {};      for (uint i = 0; i < enemies.length(); i++) {        if (enemies[i].state == STATE_LYING)            continue;          if (enemies[i].blink != 0)            continue;          ret.insertLast(@enemies[i]);    }      return ret; }   array<const Info@> attackableEnemiesByDistance() {    array<const Info@> attackable_enemies = attackableEnemies();        attackable_enemies.sort(function(a,b){return closer(a,b);});        return attackable_enemies; }   int ego() {    array<const Info@> enemies = attackableEnemiesByDistance();    if (enemies.length > 0)        setEnemy(enemies[0].num);      return 0; }
