Member Function Documentation

GetUsedRandomTriggers()

template<class RandomTriggers >

RandomTriggers SpecializedResolverObject< RandomTriggers >::GetUsedRandomTriggers ( ) const

inline

Get the triggers, which were "consumed" by some rerandomisation.

This is scope independent, even though this is broken-by-design in most cases.

Definition at line 479 of file newgrf_spritegroup.h.

References ResolverObject::used_random_triggers.

ResolverObject()

template<class RandomTriggers >

ResolverObject::ResolverObject ( const GRFFile *  grffile, CallbackID  callback = CBID_NO_CALLBACK, uint32_t  callback_param1 = 0, uint32_t  callback_param2 = 0  )

inline

Resolver constructor.

Parameters

grffile	NewGRF file associated with the object (or nullptr if none).
callback	Callback code being resolved (default value is CBID_NO_CALLBACK).
callback_param1	First parameter (var 10) of the callback (only used when callback is also set).
callback_param2	Second parameter (var 18) of the callback (only used when callback is also set).

Definition at line 313 of file newgrf_spritegroup.h.

SetWaitingRandomTriggers()

template<class RandomTriggers >

void SpecializedResolverObject< RandomTriggers >::SetWaitingRandomTriggers ( RandomTriggers  triggers )

inline

Set waiting triggers for rerandomisation.

This is scope independent, even though this is broken-by-design in most cases.

Definition at line 470 of file newgrf_spritegroup.h.
