Member Function Documentation

◆ GetRandomBits()

uint32_t RailTypeScopeResolver::GetRandomBits ( ) const
overridevirtual

Get a few random bits.

Default implementation has no random bits.

Returns
Random bits.

Reimplemented from ScopeResolver.

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
