GetRandomBits()

uint32_t RailTypeScopeResolver::GetRandomBits ( ) const

overridevirtual

Get a few random bits.

Default implementation has no random bits.

Returns

Random bits.

Reimplemented from ScopeResolver.

GetVariable()

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

overridevirtual

Get a variable value.

Default implementation has no available variables.

Parameters

	variable	Variable to read
	parameter	Parameter for 60+x variables
[out]	available	Set to false, in case the variable does not exist.

Returns

Value
