[VEN]

I noticed that many coders dealing with weapon drop. Often they have problems with detection of some of the following details:

- WeaponBoxOwnerClientIndex
- WeaponDropType
- WeaponIndex
- WeaponName
- WeaponBoxEntityIndex
- WeaponEntityIndex
- WeaponBoxModel

Note: The weaponbox entity is not the actual weapon, it is the "box" entity that "contain" the weapon_* entity, i.e. the actual weapon entity. Of course weapon_* entities classnames (which equal to weapon names) are unique for the different weapon types. The actual weapon type is stored in the weapon's entity private data area that can be easily accessed via corresponding native function from the cstrike module.

This script shows how to retrieve the details that is listed above:
