Deep dive into advanced modding concepts including custom AI, world generation, and complex game mechanics.
⚠️ Expert Level Content
This guide assumes:
- • Strong C# programming skills
- • Experience with basic tModLoader development
- • Understanding of game development concepts
- • Familiarity with Terraria's internal systems
Advanced Custom AI Systems
Creating sophisticated AI behavior for NPCs and bosses requires understanding Terraria's AI framework and implementing custom logic.
State Machine AI Example
public override void AI()
{
switch ((int)NPC.ai[0])
{
case 0: // Idle state
IdleBehavior();
break;
case 1: // Chase state
ChaseBehavior();
break;
case 2: // Attack state
AttackBehavior();
break;
}
}
Custom World Generation
World generation in tModLoader allows you to add biomes, structures, and terrain features that generate naturally in new worlds.
Biome Generation
- • Custom terrain shapes
- • Unique block placement
- • Special structure generation
- • Environmental effects
Structure Systems
- • Dungeon-like structures
- • Treasure room generation
- • Multi-layer buildings
- • Loot table integration
Performance Optimization for Complex Mods
Optimization Strategies
- • Use object pooling for frequently created/destroyed objects
- • Implement efficient collision detection
- • Cache expensive calculations
- • Minimize allocations in hot code paths
