Entity Description

A point entity that handles a single flame at its origin. The flame causes heat 'damage' to other env_fire entities around it, and will eventually ignite non-flaming env_fire entities nearby, causing the fire to spread.

Note:Env_fire doesn't create a lighting effect of any sort, you have to use a flickering light for that.

Note:Env_fire doesn't work in Portal. Please see Portal:Env_Fire_fix for more details

Keyvalues

Name (targetname) <string>[ Edit ]

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

See also:  Generic Keyvalues, Inputs and Outputs available to all entities

Parentname:

Parent (parentname) <targetname>

Specifies a movement parent. An entity will maintain its initial offset from its parent. An attachment point can be added to the end of the name, separated by a comma.

Start Disabled (StartDisabled) <boolean>

Stay dormant until activated (with theEnableinput).

• health

<integer> Amount of time the fire will burn (in seconds).

• firesize

<integer> Height (in world units) of the flame. The flame will get proportionally wider as it gets higher.

• fireattack

<integer> Amount of time the fire takes to grow to full strength. Set higher to make the flame build slowly.

• firetype

<choices> Either Natural or Plasma. Natural is a general all purpose flame, like a wood fire.

• Normal
• Plasma

• ignitionpoint

<float> Amount of heat 'damage' to take before this flame should ignite.

• damagescale

<float> Multiplier of the burn damage done by the flame. Flames damage all the time, but can be made to hurt more. This number multiplies damage by 1(so 50 = 50 damage). It hurts every second.

Flags

• 1 : Infinite Duration

Forces the flame to burn forever (unless removed).

• 2 : Smokeless

Just creates the flame, no smoke is given off.

• 4 : Start On

As soon as the map loads the flame is enabled.

• 8 : Start Full

Ignore the attack time and simply start fully built.

• 16 : Don't Drop

The entity will not drop down to the floor when spawned (i.e. it will float mid-air where it is placed).

• 32 : No Glow

Turns off the light the flame gives off (a flickering orange dynamic light). Makes the fire less expensive to render.

• 128 : Delete When Out

Delete the entity all together when the flame goes out.

• 256 : Visible from above (in all games since )

Note: Under certain circumstances, this flag may cause the map to crash when run
