Enum DebugDrawSpace

Specifies the coordinate space in which a debug draw command is interpreted and rendered.

Namespace: Scylla.Core.Util.DebugDraw

Assembly: ScyllaCore.dll

Syntax

public enum DebugDrawSpace

Remarks

The two spaces correspond to the two separate materials and rendering paths managed by DebugDrawManager:

World: The world material sets ZTest LEqual so that debug shapes are occluded by scene geometry closer to the camera. A single world-space mesh is built from all world commands and submitted via Graphics.DrawMesh for all active Game cameras simultaneously.
Screen: The screen material sets ZTest Always so that debug shapes are drawn unconditionally on top of all scene geometry. A separate screen-space mesh is built and submitted per camera because the pixel-to-world coordinate transformation differs per camera.

Scene View cameras are excluded from screen-space rendering because pixel coordinates are only meaningful in the Game View. Screen-space shapes will not appear in the Scene View panel even during Play mode.

Fields

Name Description

Screen

Name	Description
Screen	Screen-space pixel coordinates with no depth testing (`ZTest Always`). Shapes always render on top of all scene geometry, regardless of depth. The coordinate origin `(0, 0)` is at the bottom-left corner of the screen, matching Unity's `GL.LoadPixelMatrix()` convention. The X axis increases rightward and the Y axis increases upward. The top-right corner is at `(Screen.width, Screen.height)`. A separate mesh is built and submitted per Game camera because pixel coordinates must be converted to world coordinates using each camera's individual viewport transform. Scene View cameras are not included. Screen-space shapes will not appear in the Scene View panel because pixel coordinates have no stable mapping to the Scene View's continuously changing viewport.
World	World-space 3D coordinates with standard depth testing (`ZTest LEqual`). Shapes are occluded by scene geometry that lies between them and the camera. Coordinates are interpreted as standard Unity world-space positions. A single mesh is built from all world-space commands and rendered for all active Game cameras via `Graphics.DrawMesh` with `Matrix4x4.identity`. During Play mode in the Editor, world-space shapes are also drawn into open Scene View panels via `Graphics.DrawMeshNow` through the `SceneView.duringSceneGui` callback.

Screen-space pixel coordinates with no depth testing (ZTest Always). Shapes always render on top of all scene geometry, regardless of depth.

The coordinate origin (0, 0) is at the bottom-left corner of the screen, matching Unity's GL.LoadPixelMatrix() convention. The X axis increases rightward and the Y axis increases upward. The top-right corner is at (Screen.width, Screen.height).

Scene View cameras are not included. Screen-space shapes will not appear in the Scene View panel because pixel coordinates have no stable mapping to the Scene View's continuously changing viewport.

World

World-space 3D coordinates with standard depth testing (ZTest LEqual). Shapes are occluded by scene geometry that lies between them and the camera.

Coordinates are interpreted as standard Unity world-space positions. A single mesh is built from all world-space commands and rendered for all active Game cameras via Graphics.DrawMesh with Matrix4x4.identity. During Play mode in the Editor, world-space shapes are also drawn into open Scene View panels via Graphics.DrawMeshNow through the SceneView.duringSceneGui callback.
