Env fire

env_fire on top of a pile of trash

Entity description

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

Note:The fire may fall through the world on spawn if placed exactly at ground level. Place it a little bit above the ground to fix this.

Bug:This entity doesn't work in Portal. Please see Portal:Env_Fire_fix for more details  [todo tested in ?]

Bug:While still available, it does not have particle effects in Team Fortress 2. This method is recommended instead.  [todo tested in ?]

Bug:While still available, it does not currently work correctly in your Source 2007 based mod until you build(/rebuild) the project.  [todo tested in ?]
