Detailed Description

An AssetImage in which all tiles are stored sequentially in memory.

This doesn't store any separate tilemap information, just the index for the first tile in the sequence.

Generate a PinnedAssetImage by passing the pinned=1 option to image{} in your STIR script.

Pinned assets are required for sprites, since the hardware requires all tiles in a sprite to be sequential.

Pinned assets may also be efficient to use in other cases when there's very little potential for tile deduplication.

Member Function Documentation

uint16_t Sifteo::PinnedAssetImage::tile ( unsigned i ) const

inline

Returns the index of the tile at linear position 'i' in the image.

The returned index is unrelocated; it is relative to the base address of the image's AssetGroup.

uint16_t Sifteo::PinnedAssetImage::tile	(	Int2	pos,
		unsigned	frame = `0`
	)		const

inline

Return the index of the tile at the specified (x, y) tile coordinates.

The returned index is unrelocated; it is relative to the base address of the image's AssetGroup.

uint16_t Sifteo::PinnedAssetImage::tile	(	_SYSCubeID	cube,
		unsigned	i
	)		const

inline

Returns the index of the tile at linear position 'i' in the image.

The returned index is relocated to an absolute address for the specified cube. This image's assets must be installed on that cube.

uint16_t Sifteo::PinnedAssetImage::tile	(	_SYSCubeID	cube,
		Int2	pos,
		unsigned	frame = `0`
	)		const

inline

Return the index of the tile at the specified (x, y) tile coordinates.

The returned index is relocated to an absolute address for the specified cube. This image's assets must be installed on that cube.
