This entity is not in the FGD by default.
It should not be put directly in a map because it can only be configured through code in Steam versions of the game. You still can use it in mod version of the game via Hammer.

Hornet's model in Steam versions of the game.

Hornet's model in the mod version of the game.

grenade_hornet is a point entity available in Black Mesa. The grenade entity that used by weapon_hivehand and alien grunts. It is a xen hornet that spawns hivehand to attack enemies. With primary attack, player's hornet can home in on targets (if it notices them) and bounce off walls if it collides with them, explodes after a certain amount of time. With secondary attack, hornet will fly forwardly until it hits an object or until explodes after a certain amount of time. This entity also used by alien grunts, they can use only secondary attack.

Represented by class CGrenade_Hornet.

Bug:Level transition will break the detonation timer, causing this entity. This situation crash entire game after a while. In the mod version, hornet explodes after next level loaded.

Bug:This grenade entity can stuck at dynamic (not physics) objects, such as prop_dynamic. In such situation, hornet will turn at the certain direction and will not move until it explodes. Usually happens with objects that have a dynamic collision, or objects that are in motion.

Tip:If you need to fix this issue, use trigger_hurt that will kill stucked hornets, this trigger should be toggled by logic_timer every 0.5-1.0 seconds.

Example.

Example with 50 caliber machine gun. Example with a xen flora.

(not in )

Note:Only in Black Mesa (the mod version) this entity can hit physical object with primary attack. In Steam version, this entity will bounce from it such object.

Note:Only in Black Mesa (the mod version) this entity can create decal and impact sound when bounce. Example.

Note:Only in Steam versions this entity bounce from player ally NPCs (primary attack only).

Note:Particles from this entity are different in mod and last Steam versions.

Example.

This is how it looks like in current Steam versions of the game. This is how it looks like in the mod version.

Note:It explodes if hits skybox in the mod version. In Steam versions, it just disappears.

Inputs

DisableSeeking <void> (only in )

Fired by this entity if player used secondary attack of hivehand. This input disallows hornet to bounce and change flight direction.

SetSwarmingWithStartingAngle <float> (only in )

Fired by this entity if player used secondary attack of hivehand. Its use in a normal situation will cause hornet no longer bounce properly.

SetSwarmingWithNoiseFactor <float> (only in )

Fired by this entity if player used secondary attack of hivehand. Gives shaking during flight.

Note:Hornet may will note bounce properly after this input.

SetSwarmingWithRadiusScale <float> (only in )

Sets size of loop during flight.

SetTarget <string> (only in )

Sets specified target to force hornet fly and hit the target.

StopHoming <void> (only in )

Fired by this entity if player used secondary attack of hivehand. This input disallows hornet to bounce and change flight direction.

StartHoming <void> (only in )

Allows hornet to bounce.

SetTimer <float> (only in )

Sets amount of time before detonate.

Detonate <void> (only in )

Detonates hornet.

Fired by this entity when appears via player's hivehand. Doesn't do anything.

Outputs

OnDetonate <void> (only in )

Fired by this entity when detonated.
