env_warpball is a point entity available in all GoldSrc GoldSrc games. It was added in the Dreamcast and Playstation 2 ports of Half-Life. It is used in Half-Life: Decay Half-Life: Decay and Half-Life: Blue Shift Half-Life: Blue Shift. Even the PC version of Blue Shift uses this.


env_warpball is the warp-in effect when aliens from Xen teleport into a location. It can be seen in Half-Life and its expansions. It was first named in the Dreamcast version of Half-Life: Blue Shift.

In Half-Life Half-Life and Half-Life: Opposing Force Half-Life: Opposing Force, the warpball effect is a combination of entities producing sprites, beams, and sound effects. It appears as a small flashing transparent green ball that emits green light with energy beams projecting out of it. This method was replaced in the Dreamcast port of Half-Life with env_warpball, a single entity which handles the effect's creation. This allowed for easier placements of the effect in the maps by level designers. They can be obstructed to prevent the enemies from teleporting in. In Blue Shift and later installments, warpballs damage the player when in close proximity. This was most likely added to discourage the player from blocking them.
