Instantiate Unity

To do so, you first need to start by creating a new folder and naming it "Resources" You put whatever you want to load in the script in the folder, textures, prefabs, all that stuff. So if you want to Instantiate a prefab, you would simply put this in the code. var boat : GameObject = (Resources.Load("Boat")); Instantiate(boat, location, rotation); Simple right? If you want to get something out of a folder in the resources folder you just say: var smallBoat : GameObject = (Resources.Load("folder name/Small Boat")); Ta da. Easy.

Unity has on their site free packages and extentions you can download and get amazing prefabs. Such as this explosion prefab.
