env_firesensor is a point entity available in all Source Source games. It detects changes in heat from nearby env_fires.

C++ In code, it is represented by theCEnvFireSensorclass, defined in thefire.cppfile.

Flags

Start On : [1]

Keyvalues

Radius (fireradius) <float>
The radius around this entity in which to detect heat changes.
Heat level (heatlevel) <float>
The target heat level to check for. Outputs are fired when the heat moves over this target level (increasing or decreasing).
Time at level (heattime) <float>
The amount of time the heat level must spend over the target level before the 'OnHeatLevelStart' output is fired.
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.
