Entity Description
Note:env_fire doesn't create a lighting effect of any sort, you have to use a flickering light for that.Keyvalues
Targetname:
- Name <string>
- The targetname other entities refer to this entity by.
Parentname:
- Parent
<targetname> - Specifies the targetname of this entity's movement parent. Entities with parents move with their parent.
EnableDisable:
- Start Disabled
<bool> - Stay dormant until activated (probably with the Enable input).
- 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
- Note: Under certain circumstances, this flag may cause the map to crash when run
