Member Function Documentation

◆ GetRandomBits()

uint32_t RoadTypeScopeResolver::GetRandomBits ( ) const

overridevirtual

Get a few random bits.

Default implementation has no random bits.

Returns: Random bits.

Reimplemented from ScopeResolver.

◆ GetVariable()

uint32_t RoadTypeScopeResolver::GetVariable	(	uint8_t	variable,
		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
