  • Method Details

    • values

      public static CollisionPositions[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static CollisionPositions valueOf​(java.lang.String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
      java.lang.NullPointerException - if the argument is null

    • calcPosition

      public Coordinates<java.lang.Double> calcPosition​(Coordinates<java.lang.Double> topLeft, Dimension dimension)
      Return the position calculate in a rectangle
      Parameters:
      topLeft - the top-left point
      dimension - the dimension of the rectangle
      Returns:
      the position calculate in a rectangle

    • calcTopLetHitBox

      public static Coordinates<java.lang.Double> calcTopLetHitBox​(Entity entity)
      Calc and return the top left point of the hit-box of the entity
      Parameters:
      entity - an entity
      Returns:
      the top left point of the hit-box of the entity

    • calcTopLetHitBox

      private static Coordinates<java.lang.Double> calcTopLetHitBox​(Coordinates<java.lang.Double> topLeftDimension, Dimension dimension, Dimension hitBox)
      Calc and return the top left point of the hit-box matching to an entity with describe by : a top left position of the dimension, a dimension size and a hit-box size
      Parameters:
      topLeftDimension - a top left position of the dimension
      dimension - a dimension
      hitBox - a hit-box
      Returns:
      the top left point of the hit-box matching to an entity with describe by : a top left position of the dimension, a dimension size and a hit-box size

    • isInHitBox

      public static boolean isInHitBox​(Coordinates<java.lang.Double> topLeft, Dimension dimension, Coordinates<java.lang.Double> collisionPoint)
      Return if the collisionPoint given is contain in the hit-box described by the topLeft point and the dimension. The hit-box is a rectangle, with a left-top point and width/height are determined by dimension. The points is contain in the rectangle if the condition are satisfied : -his X is contain between the minX and maxX of the rectangle, between coords.getX() and coords.getX() + dimension.getWidth() -his Y is contain between the minY and maxY of the rectangle, between coords.getY() and coords.getY() + dimension.getHeight()
      Parameters:
      topLeft - the top-left points of the rectangle
      dimension - the dimension of the rectangle
      collisionPoint - a point
      Returns:
      if the collisionPoint is include in the rectangle described by the topLeft point and the dimension.

    • simplyCollide

      Return if there is a collision between the 2 entity The type of calculation used to do that is simplest than the usual way to do that
      Parameters:
      entity1 - an entity
      entity2 - an entity
      Returns:
      if there is a collision between the 2 entity, with a simple kind of calculation
