Public Member Functions
virtual RectangleF	GetDrawLocationScreen (View view)
	Converts the tile's world location to screen coordinates based on the specified view.
virtual RectangleF	GetCollisionAreaScreen (View view)
	Converts the tile's collision area from world coordinates to screen coordinates.
virtual void	Draw (BackbufferBase backbuffer, RectangleF destRectScreen)
	Renders the tile to the specified backbuffer at the given screen location.

Properties
static List< Tile >	TilesAnimating = new() `[get]`
	Gets the collection of all tiles that are currently animating in the scene. Used to track and update animated tiles during the render cycle.
bool	IsPositionFixed `[get]`
	Gets a value indicating whether the tile's position is fixed in screen space (e.g., UI elements) or moves with the world (e.g., game objects).
Rectangle	DrawLocationWorld `[get]`
	Gets the tile's draw location in world coordinates as a rectangle. This represents the area occupied by the tile in the game world.
PointF	SceneLayerCoordinates `[get]`
	Gets the tile's position within its scene layer using the layer's coordinate system.

string?	Nickname `[get, set]`
	Gets or sets an optional friendly name for the tile, useful for debugging and identification.
virtual bool	Visible `[get, set]`
	Gets or sets a value indicating whether the tile is visible and should be rendered. Setting this property triggers a refresh of the tile's screen area.
virtual int	ZOrder `[get, set]`

virtual Overhang	OverhangPixels `[get]`
	Gets the overhang dimensions (in pixels) that extend beyond the tile's primary area. This is typically used for tiles with visual elements that exceed their logical boundaries.
virtual Frame	CurrentFrame `[get, set]`

	Gets or sets a value indicating whether the tile's animation is currently paused.
virtual ? ICollider	Collider `[get]`
	Gets the collider used for collision detection with this tile. Returns null if the tile has no collision detection.
virtual Rectangle	CollisionArea `[get]`
	Gets the effective collision area of the tile in world coordinates, incorporating any adjustments specified by AdjustCollisionArea.
virtual bool	EnableFog `[get, set]`
	Gets or sets a value indicating whether fog of war rendering is enabled for this tile. Setting this property triggers a refresh of the tile's screen area.
virtual Point[]	OutlinePointsWorld `[get]`
	Used to determine polygonal area when drawing grid lines or fog. Override this property in a derived class to define custom areas for these effects.
virtual CollisionDetectionAdjustment	AdjustCollisionArea = CollisionDetectionAdjustment.None `[get, set]`
	Gets or sets the collision area adjustment values that modify the tile's collision boundaries. Use this to fine-tune the collision detection area relative to the tile's visual bounds.
TypedValueBag	ValueBag = new() `[get]`
	Gets the value bag for storing arbitrary typed values associated with this tile. Useful for attaching custom game-specific data without subclassing.

Detailed Description

Represents an abstract base class for drawable tiles in the Gondwana engine. Provides core functionality for rendering, animation, collision detection, and scene layer integration.

Member Function Documentation

◆ CompareTo()

int Gondwana.Drawing.Tile.CompareTo ( Tile? tile )

Compares this tile to another tile for sorting purposes. Fixed-position tiles are rendered first, followed by tiles sorted by Y-coordinate, Z-order, and X-coordinate.

Parameters

tile	The tile to compare with this instance.

Returns: A negative value if this tile should be drawn before the other tile, zero if they have the same draw order, or a positive value if this tile should be drawn after the other tile.

◆ Dispose()

virtual void Gondwana.Drawing.Tile.Dispose ( )

virtual

Releases all resources used by the tile, including removing it from animation tracking, disposing its animator, and clearing collision references.

Reimplemented in Gondwana.Drawing.Sprites.Sprite.

◆ Draw()

virtual void Gondwana.Drawing.Tile.Draw	(	BackbufferBase	backbuffer,
		RectangleF	destRectScreen )

virtual

Renders the tile to the specified backbuffer at the given screen location.

Parameters

backbuffer	The backbuffer to render to.
destRectScreen	The destination rectangle in screen coordinates where the tile should be drawn.

Implements Gondwana.Drawing.IDrawable.

◆ GetCollisionAreaScreen()

virtual RectangleF Gondwana.Drawing.Tile.GetCollisionAreaScreen ( View view )

virtual

Converts the tile's collision area from world coordinates to screen coordinates.

Parameters

view	The view containing camera and viewport information for the transformation.

Returns: The tile's collision area in screen space as a rectangle.

◆ GetDrawLocationScreen()

virtual RectangleF Gondwana.Drawing.Tile.GetDrawLocationScreen ( View view )

virtual

Converts the tile's world location to screen coordinates based on the specified view.

Parameters

view	The view containing camera and viewport information for the transformation.

Returns: The tile's location in screen space as a rectangle.

Implements Gondwana.Drawing.IDrawable.
