Detailed Description

template<typename Tbase, typename Tspec, typename Tobj, typename Textra, uint16_t(*)(CallbackID callback, uint32_t param1, uint32_t param2, const Tspec *statspec, Tobj *st, TileIndex tile, Textra extra_data) GetCallback, typename Tframehelper>
struct AnimationBase< Tbase, Tspec, Tobj, Textra, GetCallback, Tframehelper >

Helper class for a unified approach to NewGRF animation.

Template Parameters

Tbase	Instantiation of this class.
Tspec	NewGRF specification related to the animated tile.
Tobj	Object related to the animated tile.
Textra	Custom extra callback data.
GetCallback	The callback function pointer.
Tframehelper	The animation frame get/set helper.

AnimateTile()

template<typename Tbase , typename Tspec , typename Tobj , typename Textra , uint16_t(*)(CallbackID callback, uint32_t param1, uint32_t param2, const Tspec *statspec, Tobj *st, TileIndex tile, Textra extra_data) GetCallback, typename Tframehelper >

static void AnimationBase< Tbase, Tspec, Tobj, Textra, GetCallback, Tframehelper >::AnimateTile ( const Tspec *  spec, Tobj *  obj, TileIndex  tile, bool  random_animation, Textra  extra_data = 0  )

inlinestatic

Animate a single tile.

Parameters

spec	Specification related to the tile.
obj	Object related to the tile.
tile	Tile to animate changes for.
random_animation	Whether to pass random bits to the "next frame" callback.
extra_data	Custom extra callback data.

ChangeAnimationFrame()

template<typename Tbase , typename Tspec , typename Tobj , typename Textra , uint16_t(*)(CallbackID callback, uint32_t param1, uint32_t param2, const Tspec *statspec, Tobj *st, TileIndex tile, Textra extra_data) GetCallback, typename Tframehelper >

static void AnimationBase< Tbase, Tspec, Tobj, Textra, GetCallback, Tframehelper >::ChangeAnimationFrame ( CallbackID  cb, const Tspec *  spec, Tobj *  obj, TileIndex  tile, uint32_t  random_bits, uint32_t  trigger, Textra  extra_data = 0  )

inlinestatic

Check a callback to determine what the next animation step is and execute that step.

This includes stopping and starting animations as well as updating animation frames and playing sounds.

Parameters

cb	The callback to actually call.
spec	Specification related to the tile.
obj	Object related to the tile.
tile	Tile to consider animation changes for.
random_bits	Random bits for this update. To be passed as parameter to the NewGRF.
trigger	What triggered this update? To be passed as parameter to the NewGRF.
extra_data	Custom extra data for callback processing.
