baseprojectile

baseprojectile is a point entity available in Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two, and Half-Life 2: Deathmatch.

This entity is not in the FGD by default.
It should not be put directly in a map.

It is a base class for sprite-based projectiles. It seems to have never been used for anything in Half-Life 2.

This entity should not be confused with CBaseProjectile, which is tied to proj_base.

In code, it is represented by theCBaseSpriteProjectileclass, defined in thecbasespriteprojectile.cppfile.
