💡 Gatherers

A continuation of the 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.
• Draw scaled down versions of entities in the minimap instead of coloured blocks.
• Selectable renderer: Direct3D.
• Engine:
  • Homebrew renderer (DIBSECTION)...
  • Pre-processing...
  • Post-processing...
  • Networking...
  • Sound...
  • 3D spectator mode...
• Crossplatform support: Refactor IO, clock, etc...
• Mouse wheel zoom in or out.
• 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.
• Tiled backdrop for very large maps.
• Fixed point arithmetic?
• New assets...

🔹 May 2025 Updates

• Rough-in pathfinding optimizations.
• Rough-in renderer dirty zones.
• Memory pools for critical allocation paths (pathfinding).
• Refactor existing mallocs to use memory pools where applicable.
• Change constant #defines 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.

🔹 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.

• General code review and distance calculations.
• Note: Dev-C++ generates _private.h/.rc files by default — aligned these with main.rc where applicable.
