tConfig is best described as a content creation tool and content loader, where the content can be: items (weapons, armor, potions, accessories), tiles (blocks, furniture, crafting stations), projectiles (stuff that goes flying through the air), and NPCs. By using tConfig, all of these things can be created and organized into Mod Packs - folders containing modified or custom content. The main features are: Modify & Create Items Armor - Set Bonuses and other effects defined using C# Accessories - Effects defined using C# Weapons - Add debuff effects to enemies or alter various variables using C# Write Save & Load methods to save any data related to your custom item Modify & Create Projectiles Define unique AI using C# Modify & Create Buffs (requires C#) Modify & Create NPCs Town NPCs - Setup shops; define dialogue, spawn requirements Enemy mobs - Define AI, spawn conditions Use custom Gore images Define an interface. Make an NPC which can enchant items, for instance. Modify & Create Tiles Create new Active/Inactive blocks, Furniture, and more Modify the world when it is generated - Add new ores, place items in chests, do whatever you like! (Advanced programming may be required...) Modify & Create Walls Optionally use Visual Studio to have more control over your code Add new sound effects for use with Items and NPCs 'ModPack Builder' tool that compiles INI files and .cs code files into a single file Multiplayer - works only if you have the same mods loaded as the server New save file format for worlds - save files are named after the world names, and there is no longer any limit to the number of worlds you can have.
