If this thread is inaccurate . . . lock it? no point trolling This tutorial will teach you how to create your own entities and use additional entities in your map. First off, an entity is pretty much anything which isn't already defined as a material, model or world brush, this includes the player. This first section will be brief and I advise only decent programmers or intelligent people view it http://developer.valvesoftware.com/wiki/Your_First_Entity By creating your own entities you have absolute freedom to create what ever you want - Including entirely new weapons and characters. Along with sounds, textures and models they could be added to your specific map and still work within TF2. __________________________________________________________________________________________________________________________________ Now for the more useful section. There are many custom entities floating around on the internet which you may find useful - yet more commonly you might want to nab entities from different games. I'm going to show you how to do this: Custom FDG's: Any custom FDG's you download, you're going to want to extract to this location. Program Files -> steam -> steam apps -> [Your User Name] -> sdk -> bin Adding new entities: It is actually very easy, open up hammer and go to tools -> options. From there just select add and direct to your FDG's. You're done - new entities __________________________________________________________________________________________________________________________________ You can snatch entities from other games, most will be useless [weapon_shotgun for instance] yet there are a few golden ones Valve missed out on. An example of a relevant TF2 entity you could create is an alternate KoTH type. Where you gain time for standing in a certain area rather then having to capture it first. Time goes up as well, rather then down.
