Now we’ll add some entities to the map. Entities are objects which have behaviors, and which can (usually) be interacted with somehow.

This page covers point entities, which are those that exist at a single point on the grid. Brush entities, covered by the next article, are slightly different.

---

Switch to the Hammer Entity Tool.

Entities are placed using the Entity tool . Select it with ⇧ Shift+E, or from the left-hand icon bar.

---

Select the entity type.

Next we pick which entity to insert. There is a list of available entities in the Object Toolbar, which is in the lower-right corner of the Hammer window. Dica:You can search the list by typing into its text box. There is rarely any need to scroll around. The one that we want at the moment is a spawn location for the player. Its exact name varies slightly. See Category:Player spawn entities for a list. Singleplayer game: info_player_start Deathmatch game: info_player_deathmatch Team game: info_player_<team> (red/blue, terrorist/counterterrorist, axis/allies, etc.)

Left-click on the floor in the 3D View to place the starting entity.

Now we’ll place this entity in the map. When placing entities aligned with a surface, you can do this simply by clicking where on the surface you want it in the 3D View, so click somewhere on the floor of the room, like in the image here, and the entity will be placed at the spot you click: Dica:You can also position entities by clicking in a 2D view and dragging around the crosshairs that appear. When you’re happy, with your mouse still over a 2D view hit ↵ Enter to create the entity. (Dragging works after they’ve been created too!)

Placing Guns

Pick the weapon_357 from the entity list...

..and place it on the floor.

Many Source games involve shooting guns, so let’s place one. Weapons also vary from game to game, of course, but they always have names starting with weapon_. Notar:You do not need to place weapons down for Team Fortress 2, as the retrieval is automated. You can search the entity list for that term to see a list of what’s available. If you're working with anything related to Half-Life 2 you'll have the option of creating a weapon_357, like this: Depending on the rules of the game you’re working with, you may need to create ammunition for the gun too before the player is able to fire it. Not all games provide ammo entities however, and it’s not obvious which ammo type goes with which weapon even for those that do. Try searching for item_ammo_ entities, but if that fails you can always use the Developer Console to enable cheats, and then give yourself ammo (after picking the weapon up) with the givecurrentammo command.

Compiling

Once a player start exists you can compile your map and walk around in it, hopefully without seeing any strange warnings. If you want to do this now, skip ahead to Saving and Compiling.
