# 💡 **Gatherers**

A continuation of the [Gatherers-Legacy](https://github.com/Broosky/Gatherers-Legacy) StarCraft-style simulation. Active development continues here when time allows. See the legacy repo for early progress and design context.

## 🔹 Ideas & Upcoming Changes

- Optimize pathfinding...

  - Selectable pathfinding mode: raycast (original), bisection...

  - Memoize pathfinding points, or compute full path + memoize.

  - For main pathfinding points, curve the transitions such that the movement is not jagged.

- Move entity resource diagnostic rendering out of entity rendering logic.

- Selectable renderer: Direct3D.

- Engine:

  - Homebrew renderer (DIBSECTION)...

  - Networking...

  - Sound...

  - 3D spectator mode...

- Crossplatform support: Refactor IO, clock, etc...

- Mouse wheel zoom in or out.

- Asset consolidation and compression.

- Save/load sim...

  - Drop save file onto exe to quick load.

- Replace classic `char` buffer copying with modern safer alternatives.

- Double check and update `const` parameters.

- Use stack allocations instead of repetitive pointer dereferences for tight loops.

- Single vs multiple instances.

- Doxygen documentation.

- Don't allow workers to move inside an entity.

- Check include paths for Linux toolchain.

- Unit movement acceleration/deceleration + framerate independent unit movement.

- Decompose blur algorithm from SIMD to non-SIMD for better compatibility at the cost of performance.

- Fixed point arithmetic?

- New assets...

## 🔹 June 2025 Updates

- Tiled terrain + minimap.

- Engine pre/post-processing.

- Draw scaled down versions of entities in the minimap instead of coloured blocks w/optional transparency.

- Instant FPS meter alongside the long-term average.

- Pretty print signed numbers.

- Min & max client size.

- Blitter index as enum.

- Directories for the logger.

- Consolidate TTS.

## 🔹 May 2025 Updates

- Rough-in pathfinding optimizations.

- Rough-in renderer dirty zones.

- Memory pools for critical allocation paths (pathfinding).

- Refactor existing `malloc`s to use memory pools where applicable.

- Change constant `#define`s to types.

- Migrate volatile settings to file + hot reload.

- Restructure `DOUBLE_BUFFER_T` to `RENDERER_T` and allow it to operate on a renderer implementation strategy.

- Selectable renderer: wireframe, GDI single/double buffer, SDL, Direct2D.

- Modified the resource bar for large numbers: 999,999,999.

- Crop blit selective background on redraw.

- Improve log flow with trace, warning, and others + common writing functions.

- Maintenance timebase + daily bookending of log file.

- Linked list traversal helpers.

- Rough in some engine pre/post-processing.

- Experiment with frame buffer channel masking and blurs using SSE SIMD vectorization.

- Restructured menu items.

- Split large functions into smaller ones.

- Other architectural and miscellaneous changes + toolchain updates.

## 🔹 April 2025 Updates

- Updated pointer dereference style.

- Arrow keys now adjust view translation.

- Added uptime tracking.

- Combined engine logic into Win32 message loop.

- Cropped images for DC blit ops.

- Added build mode, date & time stamping.

- Toolchain updates.

- Began benchmarking capture system.

- Introduced a logging system.

- Added Visual Studio 2022 solution/project setup and formatting rules.

- Configured debug/release flags for MSVC.

- Menu structure refinements.

- Reviewed local function types.

- Images -> Assets (renamed + consolidated GDI brushes/pens).

- `#include` dependency graph organization.

- All functions to reference passed pointers & variables instead of global declarations/externs (where applicable).

- Fail fast on bad `malloc`s.

- Bump map size.

- Borderless windowed mode (escape toggleable) + other chord QoL keys.

- Consolidate MoveTo/LineTo's.

- Replace I/FPOINT structs with I/FDELTA structs where applicable.

- When building, if the entity extends past the client area, disallow it.

- Right-click -> build none.

- Comma print large positive numbers.

- Clean up sorting.

- Render + slight pathfinding optimizations.

  

## 🔹 March 2025 Updates

- Output current working directory.

- Prefixed diagnostics for clarity.

- New diagnostics: selected entities, selection box dimensions, selected workers.

- Improved double-buffer canvas stability on resize.

- Tweaked initial conditions for quicker building.

- Renamed and rearranged menu items.

- Added a diagnostics toggle-all option.

- Diagnostic colour updates.

- Assigned IDs to entities.

- Minimap:

  - Displays selection area.

  - Allows left-click translation of main view.

  - Highlights selected entities.

- Worker AI:

  - Scatters to nearest resources when multiple are selected.

- File structure reorganization.

- Added project files for:

  - Code::Blocks

  - Dev-C++

- Updated Windows/Linux toolchain support.

- Reviewed and updated typedefs, code, and comments.

- General code review and distance calculations.

- Note: Dev-C++ generates `_private.h`/`.rc` files by default — aligned these with `main.rc` where applicable.
