-atc_set_disable_ars(true)
+atc_set_disable_ars(boolean)
Disables (true) or enables (false) the use of ARS for this train. The train will not trigger ARS (automatic route setting) on signals then.
+ Note: If you want to disable ARS from an approach callback, the call to atc_set_disable_ars(true) must happen during the approach callback,
+ and may not be deferred to an interrupt(). Else the train might trigger an ARS before the interrupt fires.
# Approach callbacks
The LuaATC interface provides a way to hook into the approach callback system, which is for example used in the TSR rails (provided by advtrains_interlocking) or the station tracks (provided by advtrains_lines). However, for compatibility reasons, this behavior needs to be explicitly enabled.
