Grenade Detonation - Shootable HL2 Grenades

Another addon made out of boredom and pointless interest.

What does it do?

Grenade Detonation adds several features, the most important being the ability to shoot HL2 grenades.

Normally, grenades thrown by players and NPCs have no hitbox, thus making it impossible to shoot them. What this addon does is it creates an invisible object around the grenade, which acts as a hitbox for the grenade. This now includes SMG1 grenades.

Grenade Detonation
Dealing enough damage (can be changed via settings) to the grenade causes it to detonate, creating an explosion and dealing damage. The radius and damage of this explosion can be changed. Detonation can be induced by bullet, explosive, or all damage types, depending on your settings.

Grenade Arming
A secondary feature is the ability to arm inactive grenades. Grenade pickups (the ones that give you ammo) that are shot can be either armed or straight up detonated, depending on the amount of damage dealt (can be changed via settings)

Grenades that become armed act the same as thrown grenades, and can also be detonated by damage.

Hitbox Settings
In the hitbox settings menu, the player can choose the type of hitbox the grenades should have. It should be noted that this hitbox is not applied to inactive grenades, only the live (thrown) kind have it.

NPC/Player Grenade Dropping
A third feature is the ability for NPCs to drop live grenades when shot in the chest/stomach region. This is to mimic the idea of shooting a grenade off an enemy. This can also be disabled in the settings menu.

This feature also works for players, with separate settings specific to players.

Each feature also has a chance setting, which allows for a degree of randomness.

Physical Grenade Carrying
Enabling the physical grenade carrying setting will make NPCs and players carry a physical grenade on their model. The grenade will use the same logic as the grenade pickups, allowing it to be shot and armed/detonated depending on the damage dealt.

This feature functions separately from the hitbox-based dropping, and can be enabled/disabled alongside it.

Whitelist System
The whitelist system allows you to pick and choose which NPC models the grenade carrying/grenade dropping settings are enabled for. Each system has its own list, and models can be added and removed with relative ease.

Test Object
In the settings menu under "Hitbox Settings" there are buttons that allow you to spawn test objects that display a visual hitbox of the model that will be used. The test object can be shot to indicate whether the damage dealt would arm or detonate the grenade:

Green is the default state. If the color does not change, it means the damage was not enough to arm/detonate.

Yellow indicates that the damage would arm an inactive grenade.

Red indicates that the damage was high enough to instantly detonate the grenade.
