A flare at the beginning of d2_prison_08.

env_flare is a point entity available in Half-Life 2 series. Creates a red flare. Useful for creating a dark environment with just enough light to navigate. The flickering red light of the flare creates a tense atmosphere and a strong feeling of fight-or-die.

Tip:To make flares like the ones seen in Episode One, create a prop_physics with the model props_junk/flare.mdl. The rest (activation, burning, etc) is handled automatically. Note that this model was only added in Episode One.

Note:CFlare inherits CBaseCombatCharacter, so it can have relationships defined.
