Class AbstractBlockLogicExtension

  • public abstract class AbstractBlockLogicExtension
    extends java.lang.Object
    Manages the game logic for a block. The instances are not saved in the map save file; therfore, every data saved in the fields are lost after quitting.
    Points to a Coordinate in the map. If the content of the coordinate changes it will be removed via Map. Check if is about to be removed via isValid().
    If you want to save information in the save file you have to use and spawn an AbstractEntity.

        Creates a new logic instance if registered. This can happen before the chunk is filled at this position.
        blockId - the block at the position
        value -
        coord - the position where the logic block is placed
        null if not registered

        public static boolean isRegistered​(byte blockId)
      • getPosition

        public Coordinate getPosition​()
        This method must be named "getPosition" so that this method can implement other interfaces using this API signature
        not copy safe. never null
      • isValid

        public boolean isValid​()
        A logicblock is still valid if the pointer shows to a block with the same id as during creation.
        false if should be deleted

        dt - time in ms
