Methods

ActionUpdate(Action, GameTime, TimeSpan, float, bool)

This method is called when an Action that this object is involved in updates, which is every Microsoft.Xna.Framework.Game.Update(Microsoft.Xna.Framework.GameTime) frame. Note that this includes actions that are underlying (see Parent) and actions that aren't fully in progress yet (FullyInProgress). This object counts as involved in the action if its ActionInfo's GetInvolvedObjects<T>(ObjectCategory, bool, bool) includes this object. In general, the base method should be called for Furniture objects, since it sets deals with Dirty objects.

public virtual void ActionUpdate(Action action, GameTime time, TimeSpan passedInGame, float speedMultiplier, bool isAuxiliary)

Parameters

action Action

The action

time GameTime

The current game time

passedInGame TimeSpan

The amount of time that has passed, in game time

speedMultiplier float

The game speed multiplier, which represents how fast things should happen, which is usually determined by Speed

isAuxiliary bool

Whether this object counts as an auxiliary object. If this value is false, the object is th eGetActionObject<T>(bool)

CanExecuteAction(ActionType, ActionInfo, bool, bool)

Returns whether the given action can be executed at this map object. By default, this method returns Valid for all actions, but Furniture additionally returns custom results based on whether the furniture is Broken or based on AreUtilitiesDisabled.

public virtual CanExecuteResult CanExecuteAction(ActionType action, ActionInfo info, bool automatic, bool isAuxiliary)

Parameters

action ActionType

The action that is querying whether it can be executed.

info ActionInfo

The action info.

automatic bool

ignoreVisibility bool

Whether this object's Visibility should be ignored.

items List<StaticSpriteBatch.Item>

A list of sprite batch items that items should be added to if the batch is a MLEM.Graphics.StaticSpriteBatch.

DoUpdate(GameTime, TimeSpan, float)

Updates this map object if it is an IUpdatingObject, additionally invoking all required events.

public bool DoUpdate(GameTime time, TimeSpan passedInGame, float speedMultiplier)

Parameters

time GameTime

The game's time

speedMultiplier float

The game speed multiplier, which represents how fast things should happen, which is usually determined by Speed

Returns

bool

Draw(GameTime, object, Vector2, Color?, List<Item>)

Draws this object on the current Map, at the current Position. To draw a map object while invoking all the required events, use DoDraw(GameTime, object, Color?, bool, List<Item>).

public virtual void Draw(GameTime time, object batch, Vector2 drawPos, Color? overrideColor, List<StaticSpriteBatch.Item> items)

Parameters

GetPathCostModifier(Point)

Returns a modifier that indicates the "cost" for pathfinding over this object. If this object is a Furniture object, it has to have the NonColliding category for the returned value to have an effect. Note that, if this object moves, MarkDirtyForPathfinding(Point, int) should be invoked for its previous and resulting Position. By default, this method returns 0, meaning no additional pathfinding cost is added.

public virtual float GetPathCostModifier(Point position)

Parameters

custom bool

Whether the static reset is happening in a custom context, that is, a Household being exported normally rather than through cheats, or a custom Map being exported.

Returns

bool

Whether this object should stay on the map after the static reset. If false is returned, this object is removed.

SetMapAndValidate(Map)

Shorthand method for setting this object's Map and then calling ValidateEarly() and Validate(). If an exception occurs while validating, the exception is caught and false is returned. If moving an already validated object to a different map is desired, MoveToMap(Map, Vector2, float) should be used instead.
