Public Member Functions
void	Update (long tick)
	Updates the state of the object based on the specified tick value.
Public Member Functions inherited from Gondwana.Drawing.IDrawable
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.

void Gondwana.Drawing.Direct.IDirectDrawable.Update

(

long

tick

Implemented in Gondwana.Drawing.Direct.DirectComposite, Gondwana.Drawing.Direct.DirectDrawingBase, Gondwana.Drawing.Direct.DirectDrawingMovableBase, Gondwana.Drawing.Direct.DirectRectangle, Gondwana.Drawing.Direct.Particles.ParticleSurface, and Gondwana.Drawing.Direct.TextBlock.

Property Documentation

Mode

DirectDrawingMode Gondwana.Drawing.Direct.IDirectDrawable.Mode

get

Gets the drawing mode that determines where and how this drawable is rendered.

The drawing mode defines the coordinate space and rendering lifecycle:

• DirectDrawingMode.SceneLayer Renders in world space as part of a scene layer and is affected by camera position, zoom, and parallax.
• DirectDrawingMode.View Renders in screen space at the view level and is independent of camera movement, making it suitable for UI, overlays, and debug visuals.

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

RenderSurfaceHost

RenderSurfaceHostBase Gondwana.Drawing.Direct.IDirectDrawable.RenderSurfaceHost

get

The rendering surface to which this drawable belongs.

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

ScreenBounds

Rectangle Gondwana.Drawing.Direct.IDirectDrawable.ScreenBounds

get

The bounding rectangle of this drawable in SCREEN space.

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

WorldBounds

Rectangle Gondwana.Drawing.Direct.IDirectDrawable.WorldBounds

get

The bounding rectangle of this drawable in WORLD space.

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

Event Documentation

Disposing

EventHandler<IDirectDrawable>? Gondwana.Drawing.Direct.IDirectDrawable.Disposing

Occurs when the object is being disposed.
