EditorContext class
#include <Editor/Public/EditorContext.h>

EditorContext — owns all editor UI state and panel drawing.

Called by the renderer between ImGui::NewFrame() and ImGui::Render(). All ImGui:: calls for editor panels live here, keeping editor logic separated from engine rendering code.

Function documentation

void EditorContext::BuildFrame()

Build the editor UI for this frame. Called on the render thread after ImGui::NewFrame(), before ImGui::Render().

void EditorContext::LoadScene(const std::string& path, bool bReset = true)

Load a scene file: reset registry, spawn entities, update editor state. If bReset is false, skips ResetRegistry (used for initial load into an empty world).

void EditorContext::OpenConstructEditor(const char* typeName, const char* filePath = nullptr)

Open the Construct editor and create/focus a tab for the given type name. filePath is the absolute path to the header — when provided the doc is parsed from disk.

void EditorContext::OpenEntityEditor(const char* typeName, const char* filePath = nullptr)

Open the Entity editor and create/focus a tab for the given type name. filePath is the absolute path to the header — when provided the doc is parsed from disk.

void EditorContext::OpenPrefabEditor(const std::string& filePath)

Open the Prefab editor and create/focus a tab for the given .tnxprefab file. Switches to the Asset workspace automatically.

ImVec2 EditorContext::GetViewportPanelPos() const

Returns the screen-space top-left of the 3D viewport panel (logical pixels). Updated each frame during DrawEditorViewportPanel(); valid after BuildFrame() returns.
