Duel at Dusk

November 2024

Classic turn-based Artillery Shooter

Github

A two-player, turn-based artillery game written entirely in Easy68k assembly. Players adjust angle, power and battle dynamic wind on a hostile battlefield. Delivered under tight low-level constraints, it features:

– Custom Memory Manager: Heap initialization, allocation/deallocation, block coalescing & shrinking to support bitmap rendering and dynamic projectile lifecycles without leaks

– Optimized Bitmap Renderer: Selective sprite‐sheet extraction, transparency handling & background redraws tuned for 30–40 FPS on 68k hardware

– Fixed-Point Physics (12.4): Lookup-table sine/cosine & pre-shifted multiplication enable accurate projectile trajectories under varying wind conditions

– AABB Collision System: Bounding-box checks with segmented head/body/leg hitboxes for precise impact detection using minimal cycles

7-Segment Display UI: Assembly-driven segment control renders real-time health and wind meters on simulated hardware displays

– Procedural Wind Randomization: Timestamp‐bit PRNG produces unpredictable wind speed/direction each turn

– Sprite Animations & Sound Effects: Frame‐by‐frame animations for throws and hits, plus basic sound effects for a more engaging experience.
