Inline comments:
In `@docs/test/github-actions-ci-plan.md`:
- Line 50: Update the CI planning table row for repositories without
.github/workflows so it no longer lists scheduled CI as a required new workflow;
mark scheduled or nightly CI as deferred, while retaining the required CI
action.
In `@engine/Editor/include/EditorManager.hpp`:
- Around line 30-53: Document the public editor contracts at EditorManager.hpp
lines 30-53, IEditorPanel.hpp lines 8-28, InspectorPanel.hpp lines 13-30,
LogPanel.hpp lines 10-24, SceneHierarchyPanel.hpp lines 14-31, and
ViewportPanel.hpp lines 7-24: describe initialization, frame ordering,
ownership, shutdown, lifecycle and context behavior for EditorManager and
IEditorPanel, inspector scope and material editing for InspectorPanel, log-sink
registration and ownership for LogPanel, deferred child creation for
SceneHierarchyPanel, and viewport rendering and roaming-state behavior for
ViewportPanel.
- Around line 22-28: Update EditorCreateInfo to default-initialize renderer,
window, sceneManager, and scene to nullptr, and change window’s type to
GLFWwindow*. In the editor initialization flow, validate renderer and window
before invoking VulkanAdapter::Initialize, rejecting missing required pointers
while preserving nullable sceneManager and scene behavior.
In `@engine/Editor/src/EditorManager.cpp`:
- Around line 89-119: Replace the static layout guard and dockspace flags in
EditorManager with member state, using _dockLayoutInitialized and
_dockspaceFlags, and reset the layout-initialized member in Initialize() so
docking is rebuilt after ImGui context recreation. Update the layout-building
logic to use these members, and remove the DockBuilderDockWindow binding for the
unregistered "File" panel.
In `@engine/Editor/src/InspectorPanel.cpp`:
- Around line 227-252: Update the pointer-handling branch in the property
drawing method to return the boolean result from DrawReflectedObject(ptrValue,
refClass) instead of always returning false, so nested pointer-object edits
propagate their changed state to the caller.
- Line 683: Update the ImGui::TextDisabled call displaying the GameObject UID to
pass go->GetID() as an unsigned long long via an explicit cast, matching the
%llu format specifier across platforms.
In `@engine/Editor/src/LogPanel.cpp`:
- Around line 42-45: Bound m_messages in the FetchMessages append flow by
enforcing a fixed maximum size after inserting new messages, removing the oldest
entries when the limit is exceeded. Preserve the existing append behavior and
Clear handling, and define or reuse an appropriate named maximum rather than
allowing unbounded growth.
In `@engine/Editor/src/main.cpp`:
- Around line 15-17: Add an explicit <filesystem> include in main.cpp for the
std::filesystem::path return type used by ParseProjectPath, removing reliance on
the transitive include from ProjectDescriptor.hpp.
- Around line 29-74: Update CreateRenderBaselineScene to validate each
CreateGameobject/GetGameObject result before dereferencing it, covering
animatedObject, plane, instance, culled, and light; use the existing
Core::IsValidGameObjectID and null-check pattern, and skip or safely handle
failed creations. Capture the LightComponent returned by AddComponent before
assigning color and verify it is non-null.
- Around line 125-131: Update OnUpdate so m_editor->Tick(deltaTime) runs after
BeginFrame and before OnImGuiRender, while preserving the existing BeginFrame
and EndFrame calls.
In `@engine/Editor/src/ProfilerTimelineModel.cpp`:
- Around line 22-29: In the timeline zone-processing loop, validate each zone’s
interval before computing clipped coordinates or width: skip zones where
zone.endNs is less than zone.startNs. Keep valid zones’ existing clipping and
result.push_back behavior unchanged, using the surrounding zone iteration logic
to place the guard.
In `@engine/Editor/src/ProfilerTimelinePanel.cpp`:
- Around line 205-213: Update the GPU-zone drawing loop using gpuCursor so it
accounts for the frame-relative visible interval derived from viewStart and
viewDuration. Clip each zone to that interval, skip fully outside zones, and
calculate x and zoneWidth from the clipped start and duration while preserving
the existing rendering behavior.
In `@engine/Editor/src/SceneHierarchyPanel.cpp`:
- Around line 109-119: Defer the drag-and-drop reparent operation in the
SceneHierarchyPanel traversal instead of calling Transform::SetParent
immediately. Queue the child and target transform from the CHIKA_GAME_OBJECT
payload, then apply the request after traversal alongside
CommitPendingCreateChild(), preserving the existing keep-world-transform
behavior.
- Around line 199-208: Update the scene hierarchy drag-and-drop handling around
BeginDragDropTarget so it uses a window-level drop target rather than only the
“Create GameObject” button. Cover the full hierarchy area, including empty
space, with an invisible full-size item or BeginDragDropTargetCustom using the
window rectangle, while preserving the existing CHIKA_GAME_OBJECT payload
handling and SetParent behavior.
In `@engine/Editor/src/ViewportPanel.cpp`:
- Around line 157-171: Guard all renderer-dependent paths with
_context->renderer before dereferencing it: move the viewport resize and
offscreen-texture block into the existing renderer check, and add equivalent
null checks in Tick and the selection path before CalculateRayFromScreen and the
access around the later renderer use. Preserve current behavior when a renderer
exists while safely skipping these operations when it is absent.
In `@engine/Editor/src/VulkanAdapter.cpp`:
- Around line 16-76: Update engine/Editor/src/VulkanAdapter.cpp around
VulkanAdapter::Initialize to wrap initialization after the initial Shutdown() in
try/catch, call Shutdown() in the catch handler, and rethrow. Update
engine/Editor/include/VulkanAdapter.hpp around VulkanAdapter to declare a
destructor that calls Shutdown() and delete copy/move constructors and
assignment operators, preventing duplicated ownership of Vulkan handles; apply
the cleanup/ownership changes at both listed sites.
- Around line 123-143: Remove the redundant _device->WaitIdle() call from
VulkanAdapter::GetTextureHandle before ReleaseTextureDescriptor(). Preserve
descriptor cleanup, and rely on the existing frame-fence synchronization for
retiring the previous descriptor.

Replace the
static bool first_timelayout guard with member state, and remove the stale "File" dock entry.
first_timehas static storage duration. It is set tofalseon the first frame of the process. IfShutdown()andInitialize()run again,VulkanAdapterdestroys and recreates the ImGui context, so all dock node state is lost.first_timestaysfalse, the builder block never runs again, and every panel then opens as a floating window instead of docking. Store the flag inEditorManagerand reset it inInitialize(). Apply the same change todockspace_flagsat line 70.Line 113 docks a window named "File".

Dear ImGui official source IsKeyDown GetIO MouseDelta Render NewFrame assertions💡 Result:
In Dear ImGui, the relationship between NewFrame, Render, input handling (IsKeyDown, GetIO, MouseDelta), and assertions is critical for correct operation. Core API Functions - GetIO: Accesses the ImGuiIO structure, which contains input state (mouse, keyboard, gamepad), time, and configuration flags [1][2]. - NewFrame: Initiates a new Dear ImGui frame. You must call this before submitting any widgets [2][3]. It processes inputs, updates timing, and prepares the frame [3]. - Render: Ends the Dear ImGui frame and finalizes draw data. Once called, you can retrieve the draw data using GetDrawData [2]. - IsKeyDown(ImGuiKey key): A function used to check if a specific key is currently held down [4][5]. It should be used instead of direct array access to io.KeysDown[] for compatibility with modern input APIs [6]. Input Handling Best Practices - MouseDelta: This field in the ImGuiIO structure represents the mouse movement delta and is maintained by Dear ImGui [1]. - Input Routing: Check io.WantCaptureMouse and io.WantCaptureKeyboard before NewFrame to determine if your application should process input or defer to Dear ImGui [7][1]. Assertions and Lifecycle Dear ImGui uses assertions (IM_ASSERT) to enforce correct API usage. Common reasons for assertions include: - Incorrect Lifecycle: Calling widgets before NewFrame or after Render will trigger an assertion [3]. Similarly, calling NewFrame twice without an intervening Render or EndFrame is invalid [3]. - Input Tampering: Assertions exist to ensure that input state (such as key modifiers) is not modified mid-frame by your backend or application code [8][9]. Backends should submit inputs via functions like AddKeyEvent before NewFrame, rather than modifying internal state directly during the frame [1][3]. If you encounter an assertion related to io.KeyMods or similar fields, it is often due to input events being processed after NewFrame has already started [8][9]. For further guidance, consult the official documentation in the GitHub repository, specifically the FAQ.md, the Getting Started guide, and the comments within imgui.h and imgui.cpp [10][11][12].

Dear ImGui BeginDragDropTarget last item window drop target BeginDragDropTargetCustom💡 Result:
In Dear ImGui, drag and drop functionality is centered around widgets. The standard BeginDragDropTarget function automatically uses the last submitted item in the current window as the drop target, meaning its effective bounding box is tied to that specific widget [1][2][3]. If you need a drop target that does not correspond to a standard widget—or if you need more control over the target's area—you can use the internal function BeginDragDropTargetCustom [1][3]. Key Concepts and Differences: BeginDragDropTarget: - Usage: Call immediately after submitting a widget (e.g., Button, Selectable, TreeNode) [2][4]. - Behavior: Automatically uses the bounding box of the last submitted item [1][3]. - Recommendation: This is the standard, preferred approach for most use cases [3]. BeginDragDropTargetCustom: - Usage: Defined in imgui_internal.h; requires an explicit bounding box (ImRect) and a unique ID (ImGuiID) [1][3]. - Behavior: It allows you to designate an arbitrary area as a drop target, regardless of what widgets were previously submitted [3]. - Use Cases: Subdividing an area, defining a target that covers only a portion of an item, or making an entire window or custom-drawn area (like a canvas drawn with ImDrawList) a drop target [3][5]. - Warnings: Because it is an internal API, it is subject to change. Use it only when the public API is insufficient, as it increases maintenance requirements [3]. To use BeginDragDropTargetCustom effectively, you typically combine it with the window's ID or a specifically calculated ID [3][5]: // Example usage if (ImGui::BeginDragDropTargetCustom(rect, ImGui::GetID("my_custom_target_id"))) { if (const ImGuiPayload* payload = ImGui::AcceptDragDropPayload("MY_PAYLOAD_TYPE")) { // Process payload } ImGui::EndDragDropTarget; } Always ensure you call ImGui::EndDragDropTarget only if BeginDragDropTarget or BeginDragDropTargetCustom returns true [4]. If you are working with viewports or complex docking scenarios, consider if newer additions like BeginDragDropTargetViewport (also in internal headers) might be more appropriate for your specific needs [6].

Dear ImGui imgui_impl_vulkan.cpp ImGui_ImplVulkan_RemoveTexture descriptor set lifetime command buffer draw data💡 Result:
In the Dear ImGui Vulkan backend, ImGui_ImplVulkan_RemoveTexture is a utility function provided for API symmetry that calls vkFreeDescriptorSets to release a descriptor set previously allocated via ImGui_ImplVulkan_AddTexture [1][2][3]. Because Vulkan command buffers are recorded and submitted asynchronously, you must ensure that any descriptor set passed to ImGui_ImplVulkan_RemoveTexture is no longer in use by the GPU before freeing it [4]. If you free a descriptor set while a command buffer referencing it is still being executed by the GPU (i.e., it is currently "in flight"), you will trigger a Vulkan validation error and potentially cause undefined behavior or crashes [4]. To safely manage the lifetime of these descriptor sets: 1. Synchronization: Before calling ImGui_ImplVulkan_RemoveTexture, you must ensure that all frames (command buffers) that could possibly reference this descriptor set have finished execution [4]. This is typically achieved using standard Vulkan synchronization primitives, such as waiting for the device to be idle (vkDeviceWaitIdle) or using per-frame fences to track when the command buffers are completed [4]. 2. Descriptor Pool Requirements: The descriptor pool used by the Dear ImGui backend must have been created with the VK_DESCRIPTOR_POOL_CREATE_FREE_DESCRIPTOR_SET_BIT flag if you intend to use ImGui_ImplVulkan_RemoveTexture [5][1]. If the pool lacks this flag, vkFreeDescriptorSets (and by extension, the backend's removal function) will fail. 3. Recommended Practice: For applications where textures are frequently created and destroyed, manage your own descriptor pool and ensure it is sized correctly to accommodate the Dear ImGui texture requirements [5]. It is often safer and more flexible to manage the lifetime of your descriptor sets in synchronization with your application's frame-in-flight resources rather than relying solely on the backend's convenience functions [5]. In summary, ImGui_ImplVulkan_RemoveTexture is not "command buffer aware." It is the user's responsibility to guarantee that no pending command buffers—including those currently being recorded or those submitted and awaiting execution—contain references to the descriptor set being removed [4].
