Hello, :smile: I may be interested in creating several mods for Fallout 3, but before learning the programming langage and the skills to create mods, i want to know if it is possible to use scripts to position npcs and items randomly (but following certain rules) in the world of Fallout 3. For example i want to be able to position new npcs in many interior cells, like in the metro tunnels or in the abandonned houses. Is it possible to do that ? Is there a way (by script) to detect an empty space in a room, and to position a new furniture ? Also from what i have read, Fallout 3 AI uses navmeshes so that npcs can avoid the furnitures and walls. So if for example i create a script to position new furnitures in an interior cell, is there a way to recalculate the navmesh automatically, depending on the position of the furniture, his width, his depth ? I am used to program simple video games from scratch so i have no idea if it is possible to do such things with fallout 3 scripting langage... Thanks
