From 27aba01864b4f73895a92c464e065a2230d3af5e Mon Sep 17 00:00:00 2001 From: scawful Date: Mon, 13 Oct 2025 14:28:17 -0400 Subject: [PATCH] feat(editor): enhance screen editor with title screen and inventory item icon features - Implemented title screen editing capabilities, including loading and rendering of title screen layers. - Added inventory item icon management, allowing for the display and selection of item icons within the inventory menu. - Updated the inventory creation process to ensure proper ROM loading and error handling. - Introduced new canvas components for title screen and inventory item icons, improving the user interface for editing. Benefits: - Enhances the functionality of the screen editor, providing users with tools to edit title screens and manage inventory icons effectively. - Improves user experience by ensuring robust error handling and visual feedback during inventory management. --- src/app/editor/graphics/screen_editor.cc | 235 ++++++++++++++++- src/app/editor/graphics/screen_editor.h | 24 ++ src/zelda3/screen/dungeon_map.cc | 14 +- src/zelda3/screen/inventory.cc | 177 ++++++++----- src/zelda3/screen/inventory.h | 44 +++- src/zelda3/screen/title_screen.cc | 314 ++++++++++++++++++----- src/zelda3/screen/title_screen.h | 118 +++++---- 7 files changed, 725 insertions(+), 201 deletions(-) diff --git a/src/app/editor/graphics/screen_editor.cc b/src/app/editor/graphics/screen_editor.cc index 3c7eb32e..3e435110 100644 --- a/src/app/editor/graphics/screen_editor.cc +++ b/src/app/editor/graphics/screen_editor.cc @@ -58,11 +58,19 @@ absl::Status ScreenEditor::Load() { zelda3::LoadDungeonMaps(*rom(), dungeon_map_labels_)); RETURN_IF_ERROR(zelda3::LoadDungeonMapTile16( tile16_blockset_, *rom(), rom()->graphics_buffer(), false)); - // TODO: Load roomset gfx based on dungeon ID + + // Load graphics sheets and apply dungeon palette sheets_.try_emplace(0, gfx::Arena::Get().gfx_sheets()[212]); sheets_.try_emplace(1, gfx::Arena::Get().gfx_sheets()[213]); sheets_.try_emplace(2, gfx::Arena::Get().gfx_sheets()[214]); sheets_.try_emplace(3, gfx::Arena::Get().gfx_sheets()[215]); + + // Apply dungeon palette to all sheets + for (int i = 0; i < 4; i++) { + sheets_[i].SetPalette(*rom()->mutable_dungeon_palette(3)); + gfx::Arena::Get().QueueTextureCommand( + gfx::Arena::TextureCommandType::CREATE, &sheets_[i]); + } /** int current_tile8 = 0; int tile_data_offset = 0; @@ -103,24 +111,30 @@ absl::Status ScreenEditor::Update() { // Get visibility flags from card manager and pass to Begin() if (dungeon_maps_card.Begin(card_manager.GetVisibilityFlag("screen.dungeon_maps"))) { DrawDungeonMapsEditor(); - dungeon_maps_card.End(); } + dungeon_maps_card.End(); + if (inventory_menu_card.Begin(card_manager.GetVisibilityFlag("screen.inventory_menu"))) { DrawInventoryMenuEditor(); - inventory_menu_card.End(); + } + inventory_menu_card.End(); + if (overworld_map_card.Begin(card_manager.GetVisibilityFlag("screen.overworld_map"))) { DrawOverworldMapEditor(); - overworld_map_card.End(); } + overworld_map_card.End(); + if (title_screen_card.Begin(card_manager.GetVisibilityFlag("screen.title_screen"))) { DrawTitleScreenEditor(); - title_screen_card.End(); + } + title_screen_card.End(); + if (naming_screen_card.Begin(card_manager.GetVisibilityFlag("screen.naming_screen"))) { - DrawNamingScreenEditor(); - naming_screen_card.End(); + DrawNamingScreenEditor(); } + naming_screen_card.End(); return status_; } @@ -133,16 +147,23 @@ void ScreenEditor::DrawToolset() { void ScreenEditor::DrawInventoryMenuEditor() { static bool create = false; if (!create && rom()->is_loaded()) { - status_ = inventory_.Create(); - palette_ = inventory_.palette(); - create = true; + status_ = inventory_.Create(rom()); + if (status_.ok()) { + palette_ = inventory_.palette(); + create = true; + } else { + ImGui::TextColored(ImVec4(1, 0, 0, 1), "Error loading inventory: %s", + status_.message().data()); + return; + } } DrawInventoryToolset(); - if (ImGui::BeginTable("InventoryScreen", 3, ImGuiTableFlags_Resizable)) { + if (ImGui::BeginTable("InventoryScreen", 4, ImGuiTableFlags_Resizable)) { ImGui::TableSetupColumn("Canvas"); ImGui::TableSetupColumn("Tilesheet"); + ImGui::TableSetupColumn("Item Icons"); ImGui::TableSetupColumn("Palette"); ImGui::TableHeadersRow(); @@ -160,12 +181,22 @@ void ScreenEditor::DrawInventoryMenuEditor() { tilesheet_canvas_.DrawGrid(16.0f); tilesheet_canvas_.DrawOverlay(); + ImGui::TableNextColumn(); + DrawInventoryItemIcons(); + ImGui::TableNextColumn(); gui::DisplayPalette(palette_, create); ImGui::EndTable(); } ImGui::Separator(); + + // TODO(scawful): Future Oracle of Secrets menu editor integration + // - Full inventory screen layout editor + // - Item slot assignment and positioning + // - Heart container and magic meter editor + // - Equipment display customization + // - A/B button equipment quick-select editor } void ScreenEditor::DrawInventoryToolset() { @@ -213,6 +244,59 @@ void ScreenEditor::DrawInventoryToolset() { } } +void ScreenEditor::DrawInventoryItemIcons() { + if (ImGui::BeginChild("##ItemIconsList", ImVec2(0, 0), true, + ImGuiWindowFlags_HorizontalScrollbar)) { + ImGui::Text("Item Icons (2x2 tiles each)"); + ImGui::Separator(); + + auto& icons = inventory_.item_icons(); + if (icons.empty()) { + ImGui::TextWrapped("No item icons loaded.
