DODS/Creating Weapon Spawns

While weapons can be placed in your Day of Defeat: Source level, it takes a bit of setup to make them work properly. First the entities must be added to the .FGD, then additional setup is required to keep them from despawning after a few seconds.
__TOC__
== Weapon Entities ==
While they exist in the game, the default FGD is missing all the required entities to place weapons.
You can either find a custom .FGD that has them included, or add them yourself. To add them, copy and paste this into your dod.fgd:
@BaseClass base(Targetname, Angles, Parentname, RenderFields) color(0 0 200) = WeaponItemBase
[
	input Ignite(void) : "Sets the item on fire."
	output OnIgnite(void) : "Fired when the item is set afire."
]
@BaseClass base(WeaponItemBase) = Weapon
[
	spawnflags(Flags) =
	[
		1 : "Start asleep (don't fall to ground)" : 0
	]
	output OnPlayerUse(void) : "Fires when the player +uses this weapon"
	output OnPlayerPickup(void) : "Fires when the player picks up this weapon"
	// output OnNPCPickup(void) : "Fires when an NPC picks up this weapon"
]
@BaseClass base(WeaponItemBase) = Item

If done correctly, you should now be able to select all the games' weapons from the entity list.
== Building a Weapon Spawner ==
If you just place a weapon in your map, unlike in other Valve games, it will just disappear after a few seconds. To avoid having our weapons get cleaned up before the player can reach them, we need to use point_template to create the weapon on demand. The exact implementation will depend on how you want to use the weapon spawner.
===Standard Weapon Pickup===
This is for creating a weapon that stays in the same spot and respawns after a set time. (If you don't want the respawning ability, just use a trigger_once instead of a trigger_multiple)
While we want the weapon to appear to always be present in the level when available, dropped weapon cleanup means we're going to have to fake it a bit.
You will need 4 entities: The weapon entity, a prop_dynamic with the same model, a point_template, and a trigger.
- Place the weapon entity and the prop_dynamic in the same position, and give your weapon a name. For the purposes of this guide, we'll assume your weapon is a Bazooka, and we'll simply call the entity "bazooka_wp". Under flags, check "Start Asleep".
- Place a point_template. We'll name it "bazooka_template". Under "Template 1", select "bazooka wp"
- Build a brush around your weapon, large enough that the player has to be inside it to pick up the weapon.
- Press Ctrl-T, and assign it to trigger_multiple. Set "Delay before Reset" to your desired value if you want it to have a cooldown before another player can pick it up.
- Go to outputs and add the following
	My Output 	Target Entity 	Target Input	Parameter	Delay	Only Once
	OnStartTouch	bazooka_template	ForceSpawn 	<none> 	0.00 	No
- If you want the weapon model to disappear until it's ready to be picked up again, name your prop_dynamic, then add the following to your weapon entity's outputs:
	My Output 	Target Entity	Target Input	Parameter	Delay	Only Once
	OnPlayerPickup	bazooka_prop 	TurnOff 	<none> 	0.00 	No
	OnPlayerPickup	bazooka_prop 	TurnOn 	<none> 	15.00	No
Make sure TurnOn delay matches the value you used for your trigger's "Delay before Reset".
===Weapon Crate===
Day of Defeat also lacks item_item_crate, but we can put together our own. This process will be similar to what we did before, with the addition of an env_entity_maker so we can create the weapon wherever its box is opened.
For this example we'll use the Springfield (weapon_spring) as it's the right size to fit in a weapon crate.
You will need a total of 4 entities for this.
weapon_spring - call it spring_wp. Leave all settings at defaults.
prop_physics_multiplayer - call it spring_box. Set model to supply_crate02.mdl
point_template - call it spring_template. Set Template 1 to spring_wp.
env_entity_maker - call it spring_spawner. Set Parent to spring_box and "Point_template to Spawn" to template_spring.
Set the Outputs of spring_box to the following:
	My Output 	Target Entity 	Target Input	Parameter	Delay	Only Once
	OnPlayerUse	spring_spawner	ForceSpawn 	<none> 	0.00 	No
If done correctly, when you press E on the box it should break open and the rifle should fall out.
