Isometric 2.5D Rendering: Custom IsoTransform functions project 3D coordinates (X, Y, Z) onto a 2D canvas. Includes dynamic depth sorting (Painter's Algorithm) for large buildings and units.
A* Pathfinding: Units intelligently navigate around obstacles, water, and each other using a tile-based A* algorithm. If a direct path is blocked during combat, units will dynamically recalculate a path to flank the enemy.
Collision Avoidance: Units reserve their current and next tiles, preventing them from overlapping or driving through each other.
RTS Controls: Left-click drag to select units, right-click to move or attack. Middle-click drag to pan the camera.
C&C Style Unit Spawning: UI buttons below the minimap allow you to dynamically spawn new Tanks and Soldiers at your base during gameplay.
Dynamic Zoom: Mouse wheel zooms the camera in and out seamlessly. Minimap, selection boxes, and movement coordinates mathematically adapt to the current zoom level.
Combat System: Units automatically acquire targets within range, rotate their turrets, and fire homing projectiles. Soldiers maintain distance to tanks to shoot from cover.
Destructible Environments & Base Defenses: Trees and houses have health and can be destroyed. The enemy base is protected by solid walls that must be breached or destroyed.
Distinct Particle Effects: Thread-safe particle system spawns specific visual effects based on the destruction type:
    Tanks: Massive orange/yellow explosions with semi-transparent smoke.
    Trees: Burst into green leaves and brown wood chips.
    Houses: Break apart into gray concrete blocks and red roof shingles.
    Soldiers: Crushed by tanks, leaving red blood splatters.
Dynamic Visuals: Tanks and houses show structural cracks when heavily damaged, and tanks emit faint, transparent engine smoke when their health is critical.
Crush Mechanic: Tanks can run over and instantly kill enemy infantry, leaving a distinct blood splatter.
Win/Lose State: Game detects when all units of a faction are destroyed, displays a message, and automatically resets the map.
Large Dynamic Map: 48x48 tile map featuring rivers, two tactical bridges, random lakes, and procedural scenery placement with safe-spacing algorithms.
Minimap: Transparent, click-to-pan minimap showing the map layout, units, and an exact isometric polygon representing the current camera viewport.
Tank Tracks: Tanks leave physical tread marks on the ground that align perfectly with their driving direction and slowly fade over time.
Post-Processing: Press 'F' to cycle between None, Paper, and Cuphead (Film Grain + Vignette) visual filters.

Move Camera: WASD, Edge Scrolling, or Middle-Click Drag
Zoom In/Out: Mouse Wheel
Select Units: Left-Click Drag
Move/Attack: Right-Click
Spawn Units: Click 'T' (Tank) or 'S' (Soldier) buttons below the Minimap
Minimap Navigation: Left-Click on Minimap
Toggle Filters: 'F'

Renderer: Pure Skia Canvas (No Game Engine, no FMX shapes). Everything is drawn using paths, masks, and procedural shaders.
Thread-Safe Particle Queue: Physics and AI run on a background thread. To prevent race conditions when modifying the particle list, the physics thread queues explosion requests (position + type) using a TCriticalSection, which the UI thread safely processes during the render loop.
Single-File Architecture: The complete game engine, including rendering, logic, and procedural texture generation, is contained in one highly commented file.

SkiaRTSProto.pas: The complete C&C style RTS engine in a single file.
Sample project and executable(zipped) included.

Open the project in RAD Studio (Delphi).
Ensure you have the Skia4Delphi library installed.
Run and play!
