+# World of Chaos : Dungeon and Knowledge
+
+First level should be a very hard wave defense where you need to lose, but the difficulty go higher until the player cannot defend it anymore.
+
+Add effect for item drop or mob drop for rarity with special sound and effect for legendary one.
+
+___
+
+ ## 1. Game Overview
+
+ - Name-> World of Chaos : Dungeon and Knowledge
+
+ - Genre-> Real-time Survival Base-Builder & Defense with Sandbox Construction, Tech-Tree Progression, Wave Survival, Dungeon-Crawl
+ - Platform-> Desktop (Windows, Linux)
+ - Perspective-> 2D Top-Down, Tile-Based
+ - Core Experience-> Fast-paced, responsive building + combat (akin to MOBA/RTS), layered loops reward both planning (base, tech) and moment-to-moment skill (aim, positioning).
+
+___
+
+ ## 2. High-Level Concept
+
+ - MVP Vision:
+
+	 - Sandbox Build Mode: Place walls, turrets, resource-gatherers on a grid.
+
+	 - Defense Loop: Survive waves of enemies attacking your base.
+
+	 - Round Survival Loop: Fixed-arena rounds with escalating difficulty.
+
+	 - Dungeon Crawl Loop: Enter procedural dungeon, defeat boss; failure sends boss to assault your base in next wave.
+
+
+
+ - USP (Unique Selling Points):
+
+	 - Four interlocking loops: your dungeon success directly impacts base defense.
+
+	 - Deep tech-tree: unlock new defenses, units, dungeon skills.
+
+	 - Responsive, omnidirectional movement & aiming—skill matters.
+
+___
+
+ ## 3. Core Gameplay Mechanics
+
+ - Movement & Combat:
+	 - 8-directional movement.
+	 - real-time aiming with mouse.
+	 - instant feedback on attacks & blocks.
+ - Building:
+	 - Grid-snapping placement.
+	 - rotate/flip tiles.
+	 - undo/redo.
+	 - resource cost preview.
+ - Resources:
+	 - Wood, Stone, Metal.
+	 - gathered via structures or dungeon pickups.
+ - Tech Tree:
+	 - Multi-branch:
+		 - Base Defense.
+		 - Resource Efficiency.
+		 - Dungeon Skills.
+		 - Elite Units.
+ - Enemy Waves:
+	 - Scripted + procedural mix.
+	 - includes fast scouts, heavy brutes, flying units.
+ - Dungeon:
+	 - Procedural rooms.
+	 - puzzles.
+	 - minibosses.
+	 - culminates in boss fight with unique mechanics.
+
+___
+
+ ## 4. Game Loops
+
+ - Sandbox Build (Persistent): Place/upgrade structures; plan defenses.
+
+ - Defense Wave (Dynamic): Enemies pathfind toward base; survive until timer.
+
+ - Round Survival (Arena): Fixed map, randomized spawn points; earn bonus resources per round.
+
+ - Dungeon Crawl: Voluntary loop—risk vs. reward. Dungeon boss grants tech unlock on success; on failure, boss invades next wave.
+
+ - Opinion: Prioritize implementing the Defense Wave & Sandbox Build first—they form the spine of player engagement. Then layer in Round Survival. Dungeon Crawl can initially be a single hand-crafted level to prove the loop.
+
+___
+
+ ## 5. MVP Feature List
+
+ - A. Core Systems (Week 1–3)
+
+	 - Tilemap rendering & collision (raylib tilemap module)
+
+	 - Player movement/aim/shoot
+
+	 - Basic enemy AI (pathfinding to base)
+
+ - B. Building & Resources (Week 4–6)
+
+	 - Place/destroy grid-aligned buildings
+
+	 - Resource spawn & collection
+
+ - C. Wave Defense Loop (Week 7–9)
+
+	 - Wave spawner, UI timer, win/lose conditions
+
+ - D. Tech Tree UI & Data (Week 10–11)
+
+	- Data-driven tech nodes, unlock logic, simple UI
+
+ - E. Round Survival & Score (Week 12–13)
+
+ - F. Dungeon Prototype (Week 14–16)
+
+___
+
+ ## 6. Tech-Tree Design
+
+```
+        [Resource Efficiency]──┐
+                               ├─[Advanced Turrets]──[Energy Shield]
+        [Base Armor]───────────┘                      │
+                                                      ├─[Boss Summon Tech]
+        [Trap Mastery]─────────┐                      │
+                               ├─[Dungeon Vision]─────┘
+        [Spellcraft]───────────┘
+```
+
+ - Node Details:
+
+	 - Cost in tech-points (earned per wave/dungeon).
+
+	 - Prerequisites enforce meaningful choices.
+
+	 - Strong opinion: cap tech depth to 15–20 nodes for MVP.
+
+___
+
+ ## 7. Systems Architecture
+
+ - Language: C99
+
+ - Engine: raylib (windowing, input, 2D rendering, audio)
+
+ - Modules:
+
+```
+        tilemap.c/h (grid, pathfinding)
+
+        player.c/h (movement, input)
+
+        entity.c/h (enemies, projectiles)
+
+        buildings.c/h (construction, upgrades)
+
+        waves.c/h (spawn logic)
+
+        dungeon.c/h (room gen, boss logic)
+
+        tech.c/h (tech-tree data & UI)
+
+        ui.c/h (HUD, menus)
+```
+
+ - Data: JSON or simple CSV for wave definitions, tech nodes, tile properties.
+
+___
+
+## 8. Controls & UI
+
+ - Controls:
+
+	 - WASD or arrows: Move
+
+	 - Mouse: Aim & shoot
+
+	 - 1–5: Hotkeys for building types
+
+	 - T: Open Tech Tree
+
+	 - Esc: Menu/Pause
+
+ - UI Layout:
+
+	 - Top-center: Wave timer & round
+
+	 - Bottom-left: Resource counters
+
+	 - Bottom-right: Build hotkeys
+
+	 - Center-right: Tech-tree button
+
+___
+
+## 9. Art & Audio (MVP)
+
+ - Art Style: Simple, high-contrast tiles; clear readability over detail.
+
+ - Animations: 4-frame loops for player/enemies.
+
+ - Audio:
+	 - Looping ambient track
+
+	 - SFX: construction, shooting, enemy death
+
+ - Opinion: Defer polish art until gameplay is locked; use placeholders but ensure clarity.
+
+___
+
+## 10. Success Metrics & KPIs
+
+ - Playtest Goal: Survive at least 5 waves with basic defenses.
+
+ - Performance: Stable 60 FPS on moderate hardware (Intel i5, integrated GPU).
+
+ - Engagement: Test loop—players should face meaningful choices every 30 s.
+
+___
+
+## 11. Risks & Mitigations
+
+```
+	Risk->Mitigation:
+
+Pathfinding stalls on large maps->Limit map size; use A* with node caching
+Feature creep (dungeon complexity)->Lock dungeon to 3 room types for MVP
+Balancing tech-tree overpowered->Data-driven values; expose easy tuning parameters
+```
+
+___
+
+## 12. Roadmap & Milestones
+
+ - Prototype (Weeks 1–3): Movement, tilemap, enemy pathfind.
+
+ - Alpha (Weeks 4–9): Building, resources, first 3 waves.
+
+ - Beta (Weeks 10–14): Tech tree, survival rounds, basic dungeon.
+
+ - MVP Release (Week 16): All loops functional; placeholder assets.
+
+___
+
+## 13. Next Steps
+
+ - Review GDD—prioritize any missing “must-have.”
+
+ - Scaffold C modules & basic raylib window.
+
+ - Implement tilemap + player movement immediately.
+
+ - Schedule weekly playtest to validate loops.
+
+___
+
+## how it started
+
+I give myself 2 mounth to finish this project, the roadmap can be seen in roguelike_projecct_roadmap.md
+
+the point is to challenge myself to finish a simple commercial game
+
+```c

+	int height, width;
+	float rotation;
+}	obstacle_hitbox;

+- base building and defense (kinda more like terraria)
+- dungeon exploration
+- wave survival
+- exploration ?
+- hand crafted world no procedural (only dungeon using presets parts)
+- using advanced shader using normal texture and depth of object top down 2D
+
+- load level from tiled xml
+- use tile in a 3D world, but only one layer with cartoon texture

+# 2D Roguelike with Dual Game Loops: Roadmap & Deadline
+
+This document outlines a detailed plan to create a simple 2D roguelike in C using raylib, featuring two distinct game loops: defending your base against hordes and pillaging a dungeon.
+
+---
+
+## 1. Realistic Deadline Estimate
+
+- **Overall Estimate:** **80–120 hours** of focused development time
+  *(This can be spread over several weeks if you’re working part time.)*
+
+> **Note:**
+> If you’re new to C/game development or raylib, you may want to extend this timeline by an additional 50% or more to cover learning curves and extra debugging.
+
+---
+
+## 2. Roadmap / To-Do List
+
+### A. Pre-Production and Planning (8–12 hours)
+- **Concept Design:**
+  - Define the core mechanics for both game loops:
+    - **Base Defense Mode:** Determine horde attack wave system, enemy behavior, and defensive structure mechanics.
+    - **Dungeon Pillaging Mode:** Decide on dungeon layout, exploration dynamics, enemy encounters, and reward systems.
+  - Sketch out game flow diagrams and state transitions between modes.
+- **Feature List & Scope:**
+  - Create a brief design document outlining gameplay, UI, and any score/progression systems.
+  - Prioritize features (MVP vs. additional polish) to ensure core gameplay is functional.
+- **Tool Setup:**
+  - Install and configure raylib.
+  - Set up your development environment (IDE, version control, build scripts).
+
+### B. Prototyping Basic Framework (15–20 hours)
+- **Project Setup:**
+  - Initialize a basic C project structure and integrate raylib.
+  - Create a main game loop with a game state manager to switch between modes.
+- **Basic Game Loop Implementation:**
+  - Implement a splash screen or main menu for mode selection.
+  - Add stubs for each mode (base defense and dungeon) to verify mode switching.
+- **Input and Rendering:**
+  - Set up event handling using raylib for keyboard/mouse input.
+  - Render simple shapes or sprites as placeholders for the player, enemies, and bases.
+
+### C. Base Defense Mode Development (25–30 hours)
+- **Game Mechanics:**
+  - Code enemy spawning and implement wave mechanics for base defense.
+  - Develop basic AI for enemy movement and targeting the base.
+- **Player & Base Interactions:**
+  - Create defensive structures or player-controlled defenses.
+  - Implement collision detection between enemies and the base.
+- **Visual Feedback:**
+  - Display base health/integrity.
+  - Include simple animations or state feedback (damage effects, score updates).
+- **Testing and Iteration:**
+  - Continuously test and tweak enemy behavior, spawn rates, and difficulty.
+
+### D. Dungeon Pillaging Mode Development (25–30 hours)
+- **Dungeon Generation:**
+  - Design a simple procedural (or pre-defined) dungeon layout.
+  - Implement room transitions, corridors, or tile-based map structure.
+- **Player Mechanics:**
+  - Code player movement, attacks, and possibly a simple inventory or item system.
+  - Define enemy encounters with a basic combat system and AI.
+- **Environment Interactions:**
+  - Add interactive elements such as doors, traps, or treasure chests.
+  - Implement transitions between rooms or levels.
+- **Basic Story/Progression Elements:**
+  - Integrate objectives like reaching a goal or collecting treasures.
+  - Consider power-ups or enhancements to influence later base defense rounds.
+- **Testing and Iteration:**
+  - Playtest exploration, tweak enemy difficulty, and adjust dungeon layouts to ensure engagement.
+
+### E. Integration, Polish, and Debugging (10–20 hours)
+- **Integration:**
+  - Seamlessly connect the two modes so that players can transition between them.
+  - Implement transitions (e.g., carrying over score or narrative cues).
+- **Polish:**
+  - Refine graphics and animations (using temporary assets if necessary).
+  - Add sound effects and background music for an improved player experience.
+- **Debugging & Optimization:**
+  - Thoroughly playtest for bugs and balance gameplay.
+  - Optimize performance, particularly when managing multiple on-screen entities.
+- **Final Touches:**
+  - Develop a simple scoring or progression system, if desired.
+  - Implement a basic UI for health, score, and game mode transitions.
+
+### F. Buffer and Extra Time
+- **Extra Time (Optional):** Reserve an additional **10–20%** of the total planned hours for unforeseen challenges or potential extra features.
+
+---
+
+## 3. Final Considerations
+
+- **Iteration:** Game development is iterative. Be prepared to revisit and refine early stages as new challenges or ideas arise.
+- **Scope Management:** Focus initially on a minimal viable product (MVP) that covers both game modes. Additional features can be added once core gameplay is solid.
+- **Learning Curve:** If you are less experienced with raylib or game development in C, consider using online tutorials and community forums for additional guidance.
+
+Good luck with your project!
