InteractV
Status: Beta
A dynamic NPC interaction mod for GTA V. Rival gangs start turf wars, shake down the homeless, rob shopkeepers, and react to the police, all on their own, without you needing to be involved (unless you want to be, with a paid Gamer or Partner edition).
How it works
When two NPCs (or a gang and the player) are close enough and the conditions are right, an encounter starts: they approach each other, argue, threaten, and it can escalate into a fight, a robbery, an arrest, or de-escalate peacefully, depending on the factions involved and a bit of randomness.
For richer encounters, once the scripted opening plays out, control passes to a reactive AI: NPCs keep deciding what to do next on their own, based on their faction's personality (aggressive, fearful, disciplined) and the situation around them.
Everything is fully customizable: you can add or change encounters and NPC behavior without writing any code.
