From 700c21ce961836f844075b6e226cedd6e3ec04f6 Mon Sep 17 00:00:00 2001 From: John McCardle Date: Sun, 15 Mar 2026 22:14:02 -0400 Subject: [PATCH] Phase 3: Behavior system with grid.step() turn manager - Add EntityBehavior struct with 11 behavior types: IDLE, CUSTOM, NOISE4/8, PATH, WAYPOINT, PATROL, LOOP, SLEEP, SEEK, FLEE. Each returns BehaviorOutput (MOVED/DONE/BLOCKED/NO_ACTION) without modifying entity position directly (closes #300) - Add grid.step(n=1, turn_order=None) turn manager: groups entities by turn_order, executes behaviors, fires triggers (TARGET/DONE/BLOCKED), updates cell_position and spatial hash. Snapshot-based iteration for callback safety (closes #301) - Entity properties: behavior_type (read-only), turn_order, move_speed, target_label, sight_radius. Method: set_behavior(type, waypoints, turns, path) - Update ColorLayer::updatePerspective to use cell_position Co-Authored-By: Claude Opus 4.6 (1M context) --- src/EntityBehavior.cpp | 321 ++++++++++++++++++++++++++++ src/EntityBehavior.h | 81 +++++++ src/UIEntity.cpp | 150 +++++++++++++ src/UIEntity.h | 18 ++ src/UIGrid.cpp | 184 ++++++++++++++++ src/UIGrid.h | 3 + tests/integration/grid_step_test.py | 155 ++++++++++++++ tests/unit/entity_behavior_test.py | 104 +++++++++ 8 files changed, 1016 insertions(+) create mode 100644 src/EntityBehavior.cpp create mode 100644 src/EntityBehavior.h create mode 100644 tests/integration/grid_step_test.py create mode 100644 tests/unit/entity_behavior_test.py diff --git a/src/EntityBehavior.cpp b/src/EntityBehavior.cpp new file mode 100644 index 0000000..4f8b423 --- /dev/null +++ b/src/EntityBehavior.cpp @@ -0,0 +1,321 @@ +#include "EntityBehavior.h" +#include "UIEntity.h" +#include "UIGrid.h" +#include "UIGridPathfinding.h" +#include +#include + +// Thread-local random engine for behavior randomness +static thread_local std::mt19937 rng{std::random_device{}()};
