Detailed Description

Singleton providing current render context for scene view.

Unity-like static access for gizmo implementations: auto& view = SceneView::Get(); float halfW = sprite->width * view.GetScaleX() * view.GetZoom() * 0.5f;

The SceneViewPanel calls BeginObject/EndObject to set up context for gizmo rendering. Visual content is rendered via DekiRenderSystem.

Member Function Documentation

Get()

SceneView & DekiEditor::SceneView::Get ( )

static

Get singleton instance.

GetScreenX()

float DekiEditor::SceneView::GetScreenX ( ) const

inline

Screen X position of object center.

GetScreenY()

float DekiEditor::SceneView::GetScreenY ( ) const

inline

Screen Y position of object center.

GetWorldX()

float DekiEditor::SceneView::GetWorldX ( ) const

inline

World X position.

GetWorldY()

float DekiEditor::SceneView::GetWorldY ( ) const

inline

World Y position.

GetScaleX()

float DekiEditor::SceneView::GetScaleX ( ) const

inline

World scale X.

GetScaleY()

float DekiEditor::SceneView::GetScaleY ( ) const

inline

World scale Y.

GetRotation()

float DekiEditor::SceneView::GetRotation ( ) const

inline

Rotation in radians (engine convention).

GetZoom()

float DekiEditor::SceneView::GetZoom ( ) const

inline

View zoom level (editor wheel zoom * dpi only — no PPM).

GetPixelsPerMeter()

float DekiEditor::SceneView::GetPixelsPerMeter ( ) const

inline

Pixels per meter for the active project camera (world scale).

GetWorldToScreenScale()

float DekiEditor::SceneView::GetWorldToScreenScale ( ) const

inline

World meters to screen pixels (= zoom * pixelsPerMeter).

Use this for any gizmo dimension that originates in world units (e.g. CameraComponent::GetVisibleWidth, or an emission shape's radius). For fixed-screen-size accents (crosshairs, handle dots) use GetZoom().

GetDisplayWidth()

float DekiEditor::SceneView::GetDisplayWidth ( ) const

inline

Display width (for current component).

GetDisplayHeight()

float DekiEditor::SceneView::GetDisplayHeight ( ) const

inline

Display height (for current component).

IsCurrentObjectSelected()

bool DekiEditor::SceneView::IsCurrentObjectSelected ( ) const

inline

Whether current object is selected.

GetCurrentObject()

DekiObject * DekiEditor::SceneView::GetCurrentObject ( ) const

inline

Get current object being rendered.

GetTargetWidth()

int DekiEditor::SceneView::GetTargetWidth ( ) const

inline

Project render target width in pixels (DisplaySettings.targetWidth).

GetTargetHeight()

int DekiEditor::SceneView::GetTargetHeight ( ) const

inline

Project render target height in pixels (DisplaySettings.targetHeight).

SetTargetSize()

void DekiEditor::SceneView::SetTargetSize ( int width, int height )

inline
