Contagion Protocol changes
🧠 Smarter Zombies: Pathfinding Overhaul Complete
No more zombies dumbly faceplanting into walls.
New A* Grid System: Custom-built from scratch to handle huge zombie swarms without lag.
Obstacle Padding Logic: Prevents enemies from hugging colliders. Looks better, plays smoother.
Zombie Collisions Disabled: Forget the awkward crowd-stuck shuffles — they pass through each other now, fluid and deadly.
Script Cleanup: Obsolete systems like ZombiePathScheduler are gone. Simpler logic = better performance.
Performance? We tested this thing on hordes hundreds strong — smooth like decapitated butter. 🧈🧟
🌐 Dynamic World: Occlusion-Based Tilemap Fading
Who turned out the lights? Oh, it was a tree.
New Scene: RuralAmericana_01 — your first taste of the overgrown apocalypse.
Tilemap Layers: Ground, Props, Colliders, and now FadeableProps — smart environment rendering that fades when the player walks behind obstacles.
Custom Shader + Script: A TilemapFader uses player proximity to dynamically alpha-fade occluding tiles.
Sorting by Y-Axis: Implemented camera-based sorting for pixel-perfect layering.
It’s not just pretty — it’s readable. No more losing your survivor behind a bush.
🔧 Settings That Actually Stick
Options menus shouldn’t suck. Ours don’t.
Volume Sliders: Music & SFX with FMOD support, saved with PlayerPrefs.
Resolution Dropdowns: Duplicates filtered out, fullscreen toggle works right.
UI Prefab: Works across main menu & pause menu — modular and reskinned with full pixel art polish.
Got a CRT or a 4K ultrawide? We got you.
☣️ Boss Brain Boosts
We’ve revisited the Radioactive Furnace — your bile-spewing bullet-hell nemesis.
Attack Patterns Finalized: AcidSpit, ProjectileBurst, WallBarrage, and SpiralBlast now rotate cleanly.
Summon Phase Logic: Boss becomes invincible, spawns minions, turns green with envy (and poison) until you kill them all.
Performance Polished: All FX pooled, no lag spikes, and the visuals drip with radioactive flair.
This boss doesn’t just challenge you — it tests your ability to survive a tactical nightmare.
🧪 What’s Brewing in the Lab
Future targets — because this undead machine never stops mutating:
🧱 Finish arena lockdown system for proper boss fights.
🏠 Build the Safe House for meta-progression (upgrades, currency, unlocks).
🔓 Implement extraction logic + victory triggers.
🧠 Optimize pathfinding further using flow fields or spatial partitioning.
💾 Add save system for Contagion Credits and unlocks.
💀 Join the Plague Parade
Every wishlist, follow, and comment pushes this solo-dev dream further into the necrotic light.
Made with no studio, no publisher — just code, caffeine, and a pile of zombie parts.
🖤 Wishlist the game 📢 Follow for updates 🧠 Drop feedback — your ideas fuel the swarm
Until next time — stay sharp, stay sick, and don’t stop running.
