IonAmbient
The overall light level in force while an ion storm is running, where 1 is full daylight.
Scenario lighting
Specification — Scenario lighting
- Applies to
- scenarios
- File
map file- Section
[Lighting]- Value
- floating point
- When omitted
- Context-dependentThe value this scenario's Ambient key sets in the same section, read immediately before it. With neither key present that is 1, full daylight.
[Lighting]Ambient=1IonAmbient=.5A storm does not apply this level outright: it becomes the target of the ambient fade, which walks the map down to it over several steps and back up to Ambient when the storm ends. The palette tint changes at once, so a map with a dark ion level shows its ion colors well before it shows its ion darkness.
Random map generation
Specification — Random map generation
- Applies to
- random map generation
- File
map file- Section
[Lighting]- Value
- floating point
- When omitted
- Context-dependentThe ambient level generation has just set from the seed's time of day.
Random map generation reads this entry from the hard-coded file ION.INI, and only when the seed carries UseIonStorms=yes. It replaces the value the generated map was built with, so that file is where a mod sets the storm lighting every generated map will use.
