IsEnergySourceAtReach()

bool ComponentEnergyManager::IsEnergySourceAtReach ( vector from_position, float add_tolerance = 0, vector override_source_position = "-1 -1 -1" )

inlineprotected

Energy manager: Returns true if this device's virtual power cord can reach its energy source at the given position, depending on its cordLength config parameter. Otherwise returns false.

Аргументы

from_position	vector position from where the measurement will be taken
add_tolerance	float parameter will add to the cord's length in meters (optional)

Возвращает

bool True if the power source will be at reach for the plug, or if config param cordLength is absent or 0. False if not, or is not plugged, or this device lacks Energy Manager component.
