Detailed Description

A class that represent a set of tiles that can be used in a TileLayer.

This class is compatible with the "Tiled" map editor.

Member Function Documentation

clearTiles()

void fge::TileSet::clearTiles

(

)

Clear the tiles.

computeTextureRect()

fge::RectInt fge::TileSet::computeTextureRect ( LocalTileId id ) const

nodiscard

Compute the supposed texture rectangle with a local id.

Parameters

id	The local id of the tile

Returns

The supposed texture rectangle of the tile

containsGlobal()

bool fge::TileSet::containsGlobal ( GlobalTileId gid ) const

nodiscard

Check if the global id is in the tileset.

Parameters

gid	The global id of the tile

Returns

true if the global id is in the tileset, false otherwise

getColumns()

int fge::TileSet::getColumns ( ) const

nodiscard

Return the number of columns in the texture.

Returns

The number of columns in the texture

getFirstGid()

GlobalTileId fge::TileSet::getFirstGid ( ) const

nodiscard

Get the first global id of the tileset.

Returns

The first global id of the tileset

getLocalId() [1/2]

LocalTileId fge::TileSet::getLocalId ( fge::Vector2i const & position ) const

nodiscard

Get the local id of a tile by its grid position.

Parameters

position

The grid position of the tile

Returns

The local id of the tile if found, -1 otherwise

getLocalId() [2/2]

LocalTileId fge::TileSet::getLocalId ( GlobalTileId gid ) const

nodiscard

Get the local id of a tile by its global id.

The global id is subtracted by the first global id of the tileset in order to get the local id.

Parameters

gid	The global id of the tile

Returns

The local id of the tile if found, -1 otherwise

getName()

std::string const & fge::TileSet::getName ( ) const

nodiscard

Get the name of the TileSet.

Returns

The name of the TileSet

getOffset()

fge::Vector2i const & fge::TileSet::getOffset ( ) const

nodiscard

Get the offset in pixel of the TileSet.

Returns

The offset in pixel of the TileSet

getRows()

int fge::TileSet::getRows ( ) const

nodiscard

Return the number of rows in the texture.

Returns

The number of rows in the texture

getTexture()

fge::Texture const & fge::TileSet::getTexture ( ) const

nodiscard

Get the texture of the TileSet.

Returns

The texture of the TileSet

getTextureRect()

std::optional< fge::RectInt > fge::TileSet::getTextureRect ( LocalTileId id ) const

nodiscard

Get the texture rectangle of a tile by its local id.

Parameters

id	The local id of the tile

Returns

The texture rectangle of the tile if found, std::nullopt otherwise

getTile()

fge::TileData const * fge::TileSet::getTile ( LocalTileId id ) const

nodiscard

Retrieve a tile by its local id.

Parameters

id	The local id of the tile

Returns

The tile pointer if found, nullptr otherwise

getTileCount()

std::size_t fge::TileSet::getTileCount ( ) const

nodiscard

Get the total number of tiles in the TileSet.

Returns

The total number of tiles in the TileSet

getTileSize()

fge::Vector2i const & fge::TileSet::getTileSize ( ) const

nodiscard

Get the tile size of the TileSet.

Returns

The tile size of the TileSet

setFirstGid()

void fge::TileSet::setFirstGid

(

GlobalTileId

gid

)

Set the first global id of the tileset.

The first global id correspond to the first tile id in the tileset.

Parameters

gid	The first global id of the tileset

setName()

void fge::TileSet::setName

(

std::string

name

)

Set the name of the TileSet.

Parameters

name	The name of the TileSet

setOffset()

void fge::TileSet::setOffset

(

fge::Vector2i const &

offset

)

Set the offset in pixel of the TileSet.

Parameters

offset

The offset in pixel of the TileSet

setTexture()

void fge::TileSet::setTexture

(

fge::Texture

texture

)

Set the texture of the TileSet.

This function will automatically slice the texture into tiles.

Parameters

texture

The texture of the TileSet

setTileSize()

void fge::TileSet::setTileSize

(

fge::Vector2i const &

tileSize

)

Set the tile size of the TileSet.

This function will automatically slice the texture into tiles.

Parameters

tileSize

The tile size of the TileSet

slice()

void fge::TileSet::slice

(

)

Slice the texture into tiles.

The texture will be sliced into tiles of the size specified by the tile size. Tiles is always sliced from the top left corner of the texture in a Z pattern.

Previous tiles will be cleared.

valid()

bool fge::TileSet::valid ( ) const

nodiscard

Check if the TileSet have a valid Texture.

Returns

true if the TileSet have a valid Texture, false otherwise
