◆ GetRandomBits()

uint32_t RoadStopScopeResolver::GetRandomBits ( ) const
overridevirtual

Get a few random bits.

Default implementation has no random bits.

Returns
Random bits.

Reimplemented from ScopeResolver.

◆ GetTriggers()

uint32_t RoadStopScopeResolver::GetTriggers ( ) const
overridevirtual

Get the triggers.

Base class returns 0 to prevent trouble.

Returns
The triggers.

Reimplemented from ScopeResolver.

Definition at line 62 of file newgrf_roadstop.cpp.

References st, and BaseStation::waiting_triggers.

◆ GetVariable()

uint32_t RoadStopScopeResolver::GetVariable ( uint8_t  variable,
[[maybe_unused] ] uint32_t  parameter,
bool &  available 
) const
overridevirtual

Get a variable value.

Default implementation has no available variables.

Parameters
variableVariable to read
parameterParameter for 60+x variables
[out]availableSet to false, in case the variable does not exist.
Returns
Value

Reimplemented from ScopeResolver.
