Env fire

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.

Key Values

• Name

The name that other entities refer to this entity by.

• Parent

The name of this entity's parent in the movement hierarchy. Entities with parents move with their parent.

• Start Disabled

If Yes, It doesn't start burning until it is triggered.

• Duration

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

• Size

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

• Attack

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

• Type

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

• Ignition Point

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

• Damage Scale

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

• Infinite Duration

Forces the flame to burn forever (unless removed).

• Smokeless

Just creates the flame, no smoke is given off.

• Start On

As soon as the map loads the flame is enabled.

• Start Full

Ignore the attack time and simply start fully built.

• 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).

• No Glow

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

• Delete When Out

Delete the entity all together when the flame goes out.
