From 48026421c968b41049e453d37b6a2540f3bbc102 Mon Sep 17 00:00:00 2001 From: Kelsi Date: Tue, 5 May 2026 04:14:29 -0700 Subject: [PATCH] feat(editor): NPC scatter tool, adjacent tile creation, multi-tile prep - Scatter tool: place N creatures in a radius around cursor position with random rotation and uniform disk distribution - File > Add Adjacent Tile: creates and exports a blank tile N/S/E/W of current (foundation for multi-tile zone editing) - Scatter UI: count slider (1-30), radius slider (10-200) - Scatter places all copies with same stats/behavior as template --- tools/editor/editor_app.cpp | 16 ++++++++++++++++ tools/editor/editor_app.hpp | 3 +++ tools/editor/editor_ui.cpp | 26 ++++++++++++++++++++++++++ tools/editor/npc_spawner.cpp | 18 ++++++++++++++++++ tools/editor/npc_spawner.hpp | 4 ++++ 5 files changed, 67 insertions(+) diff --git a/tools/editor/editor_app.cpp b/tools/editor/editor_app.cpp index 8bd82458..d03980c7 100644 --- a/tools/editor/editor_app.cpp +++ b/tools/editor/editor_app.cpp @@ -603,6 +603,22 @@ void EditorApp::setGizmoAxis(TransformAxis axis) { viewport_.getGizmo().setTarget(sel->position, sel->scale);
