env_entity_igniter is a point entity available in all Source games. It catches a target entity on fire. If the target is an animating model, it will have flame sprites attached to its skeleton. Otherwise the target will emit particle flame puffs.

AltNames: This entity is also tied to entityflame. See Code ↓

Code

Prior to Left 4 Dead 2 env_entity_igniter and entityflame are tied to the same C++ class called CEntityFlame. env_entity_igniter is the entity available in FGD for the mapper to setup target, lifetime and then fire Ignite input. After Ignite input is fired the game creates entityflame setting up its FlameThinker and attaching itself to the targetted entity.

Since Left 4 Dead 2 the functionality exposed to mapping i.e. lifetime keyvalue and Ignite input is stripped from CEntityFlame and instead CEnvEntityIgniter is created that solely has the purpose to initiate the ignition while entityflame remains as CEntityFlame doing the burning.
