Item battery (Black Mesa)

GoldSrc

Source Engine ( General | Half-Life: Source | Black Mesa )

edit

item_battery is a model entity available in Black Mesa. This is a portable battery that charges armor for the HEV suit when picked up. This entity also creates dynamic light source.

Placement Tip:In multiplayer maps, do not place this entity in easily accessible places and in large numbers. It's very hard to kill a player with full armor, smart players will also get a huge advantage due to the loop control of the area and using the batteries in the same place.

Note:Most objects that inherit class CBasePickup in Black Mesa have the following features:

• They're VPhysics objects (disabled in multiplayer mode).
• Respawn in multiplayer mode (item_weapon_ entities creating xen portal effects as well).
• No physics and collision in multiplayer.
• Model can be changed to your own via the parameter (which is not in the FGD by default, added in Enhanced Black Mesa FGD).

Note:Dynamic lighting from this entity is disabled in multiplayer mode. You're still able recreate it with newLight_Point entity.

Class hierarchy
CItem_battery ↳CBasePickup ↳CBaseAnimating ↳CBaseEntity

Bug:Doesn't collide with other CBasePickup and weapon_ entities (not in ).

Tip:Use this parameters for NewLight_Point to recreate the dynamic light effect for fake/non-pickable batteries or for multiplayer mode:

• Light color (lightcolor) "20 181 214 255"
• Appearance (style) "Flicker A"
• Light Intensity (Intensity) "256"
• Texture Name (texName) "lights/lightcookie_battery.vtf"
• Enable Texture Light (bTexLight) "1"
• Specular Multiplier (SpecMultiplier) "0"
• Light Type (lighttype) "2"
• Range (range) "30^[confirm]"

Tip:You can change some lighting settings for this entity in Dynlightscript.txt.

Important:Unlike the suit charger, the limit at which player can pick up a battery is hard coded, it is 100 armor.
