Inheritance diagram for Gondwana.Drawing.IDrawable:

Public Member Functions
RectangleF	GetDrawLocationScreen (View view)
	Computes the object's destination rectangle in SCREEN pixels for rendering on the Backbuffer, using the provided View to project from world-space.
void	Draw (BackbufferBase backbuffer, RectangleF destRectScreen)
	Draws the object to the Backbuffer using the provided SCREEN-space destination rectangle. The rectangle is assumed to already be projected into screen-space; no world-to-screen conversion should occur within this method.

Properties
Guid	Id [get]
	Auto-assigned unique identifier for the object.
string?	Nickname [get]
	Optional human-readable name associated with the object.
bool	Visible [get]
	Gets a value indicating whether the object is visible.
int	ZOrder [get]
	Gets the z-order of the element, which determines its visual stacking order relative to other elements. Higher z-order values are drawn on top of lower ones.

Detailed Description

Represents an object that can be drawn on a visual surface, with properties for visibility and stacking order.

The IDrawable interface defines the contract for drawable objects, including a unique identifier, optional nickname, visibility state, and z-order for determining the drawing order. Implementations of this interface must provide a mechanism to render the object via the Draw method.

Member Function Documentation

Draw()

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

Draws the object to the Backbuffer using the provided SCREEN-space destination rectangle. The rectangle is assumed to already be projected into screen-space; no world-to-screen conversion should occur within this method.

Parameters

backbuffer	The Backbuffer to draw onto.
destRectScreen	The destination rectangle in absolute SCREEN pixel coordinates on the Backbuffer.

Implemented in Gondwana.Drawing.Direct.DirectComposite, Gondwana.Drawing.Direct.DirectDrawingBase, and Gondwana.Drawing.Tile.

GetDrawLocationScreen()

RectangleF Gondwana.Drawing.IDrawable.GetDrawLocationScreen

(

View

view

)

Computes the object's destination rectangle in SCREEN pixels for rendering on the Backbuffer, using the provided View to project from world-space.

Parameters

view	The View providing camera, zoom, parallax, and viewport offsets used to convert the object's world-space bounds into screen-space.

Returns

A rectangle in absolute SCREEN pixel coordinates on the Backbuffer.

Implemented in Gondwana.Drawing.Direct.DirectComposite, Gondwana.Drawing.Direct.DirectDrawingBase, and Gondwana.Drawing.Tile.

Property Documentation

Id

Guid Gondwana.Drawing.IDrawable.Id

get

Auto-assigned unique identifier for the object.

Implemented in Gondwana.Drawing.Direct.DirectComposite, Gondwana.Drawing.Direct.DirectDrawingBase, and Gondwana.Drawing.Tile.

Nickname

string? Gondwana.Drawing.IDrawable.Nickname

get

Optional human-readable name associated with the object.

Implemented in Gondwana.Drawing.Direct.DirectComposite, Gondwana.Drawing.Direct.DirectDrawingBase, and Gondwana.Drawing.Tile.

Visible

bool Gondwana.Drawing.IDrawable.Visible

get

Gets a value indicating whether the object is visible.

Implemented in Gondwana.Drawing.Direct.DirectComposite, Gondwana.Drawing.Direct.DirectDrawingBase, and Gondwana.Drawing.Tile.

ZOrder

int Gondwana.Drawing.IDrawable.ZOrder

get

Gets the z-order of the element, which determines its visual stacking order relative to other elements. Higher z-order values are drawn on top of lower ones.

Implemented in Gondwana.Drawing.Direct.DirectComposite, Gondwana.Drawing.Direct.DirectDrawingBase, Gondwana.Drawing.Sprites.Sprite, Gondwana.Drawing.Tile, and Gondwana.Scenes.SceneLayerTile.
