From 690f77eea0f84b30d85cb2b416d3d549aa96d5a8 Mon Sep 17 00:00:00 2001 From: scawful Date: Mon, 29 Sep 2025 09:42:06 -0400 Subject: [PATCH] Implement critical fixes for tile cache issues and optimize resource management - Updated Tile16Editor to regenerate blockset atlas directly from ROM data, bypassing problematic tile cache. - Enhanced clipboard functionality to extract tile data directly from the atlas, improving reliability. - Refactored Arena class shutdown process to ensure safe cleanup of resources, preventing double-free issues. - Optimized Canvas rendering logic to utilize pre-calculated values for improved performance with large selections. --- src/app/editor/overworld/tile16_editor.cc | 28 ++++------ src/app/gfx/arena.cc | 35 +++++------- src/app/gui/canvas.cc | 67 ++++++++++++++--------- 3 files changed, 66 insertions(+), 64 deletions(-) diff --git a/src/app/editor/overworld/tile16_editor.cc b/src/app/editor/overworld/tile16_editor.cc index 6a896f4d..53fc933b 100644 --- a/src/app/editor/overworld/tile16_editor.cc +++ b/src/app/editor/overworld/tile16_editor.cc @@ -338,16 +338,13 @@ absl::Status Tile16Editor::RefreshTile16Blockset() { return absl::FailedPreconditionError("Tile16 blockset not available");
