    • getGrowPriority

      public int getGrowPriority()
      Returns the grow priority. Relative priority is used for determining which entities gets the extra space first.

      Returns:
      The grow priority.
    • setGrowPriority

      public void setGrowPriority(int p)
      Sets the grow priority. Relative priority is used for determining which entities gets the extra space first.

      Parameters:
      p - The new grow priority.
    • getGrow

      public Float getGrow()
      Returns the grow weight.

      Grow weight is how flexible the entity should be, relative to other entities, when it comes to growing. null or zero mean it will never grow. An entity that has twice the grow weight compared to another entity will get twice as much of available space.

      GrowWeight are only compared within the same GrowPrio.
