Tactical Ai Overhaul

Combat & Perception

• Realistic Line of Sight: Units see and shoot through glass and leaves.
• Suppression System: Incoming fire builds pressure on targets, degrading their accuracy until it naturally cools down.
• Smart Combat States: Uses Schmitt hysteresis thresholds to prevent rapid, erratic switching between attacking, taking cover, and retreating.
• Full Tactical Config: Dedicated configuration settings for suppression, audio detection, decay rates, and accuracy penalties.

Movement & Navigation

• Hazard Avoidance: Units actively route around lava, cacti, and dangerous blocks.
• Obstacle Clearing: NPCs break obstructing glass or leaves when pathfinding.
• Ladder Navigation: Overhauled pathfinding for reliable ladder climbing.
• Adaptive Speed: Movement speed dynamically adjusts based on tactical state (e.g., cautious peeking vs. fast retreats).

Cover & Evasion

• Dynamic Cover Search: Scans for optimal, reachable, and safe cover positions.
• Soft Cover Utilization: Smart use of non-solid or partial blocks for concealment.
• Killzone Reaction: Exposed NPCs immediately prioritize escaping, diving into cover, or firing back to suppress the threat.
• Performance Cooldowns: Search algorithms use cooldown timers to prevent game performance drops.

Squad & Audio Systems

• Audio Processing: Gunfire and bullet impacts generate tactical alerts, causing nearby NPCs to investigate, orient, or take cover.
• Squad Memory: Units share local context and remember recent engagements as a cohesive unit.

Tactical Decision-Making

• Confidence & Threat Scoring: Real-time evaluation of health, weapon status, allies, and suppression to calculate combat confidence.
• Advance vs. Hold Logic: NPCs only push forward when conditions favor it; otherwise, they hold position or set up ambushes.
• CQB Mode Trigger: Automatically shifts to aggressive close-quarters tactics when fighting indoors or at short ranges.
• Emergency Response: Critical danger events instantly override standard decision flows for immediate self-preservation.
