Extended Object Types

• CUnit

  EPDCUnitMap is another way to write CUnit
  Unit instance operation object, which can operate a specific unit on the map. In the editor, Unit actually refers to the unit type instead of the unit instance.
  CUnit is a reference type, and the unit instance it operates on belongs to data that needs to be synchronized.

  object CUnit {
      function constructor(epd) {}
      static function from_read(epd) {}
      static function from_ptr(ptr) {}

• UnitGroup

  UnitGroup is an optimized unit instance container after applying CPTricks.

  object GUnit {
      function remove(){}           // Remove itself from the UnitGroup you belong to
      const dying : EUDGUnitIter;   // It is not actually an iterator. If the unit is alive, the foreach code block will not execute. If the unit dies, after executing the code block in foreach, the dead unit will remove itself from the UnitGroup it belongs to.
  }
  
  object UnitGroup {
      function add(epd) {}
      const cp_loop : EUDGUnitIter; // cp_loop returns an iterator that iterates over all unit instances in the container. For now, let's call this unit instance type GUnit. GUnit has a remove method to remove itself from the UnitGroup it belongs to
  };

  // epScript example
  
  // UnitGroup Declaration
  const zerglings = UnitGroup(1000);
  // max capacity = 1000, will use CPTrick
  
  // Register Unit
  zerglings.add(epd);
  
  // Loop UnitGroup
  foreach(unit : zerglings.cploop) {
      // Run Triggers on **any** zerglings (alive or dead)
      foreach(dead : unit.dying) {
          // Run Triggers on dead zerglings
      }  // <- dead zergling will be removed at end of *dying* block
      // Run Triggers on alive zerglings
  }
  
  // example usage
  function afterTriggerExec() {
      const zerglings = UnitGroup(1000);
      foreach(cunit : EUDLoopNewCUnit()) {

      foreach(unit : zerglings.cploop) {
          foreach(dead : unit.dying) {
              // spawn Infested Terran when zergling dies
              dead.move_cp(0x4C / 4);  // Owner
              const owner = bread_cp(0, 0);
