Detailed Description

A manager for loading, caching, and drawing textures.

The TextureManager class is responsible for handling texture loading, caching, and rendering in the engine. It provides functions to add, load, and draw textures from files, as well as manage sprite sheets.

Textures are used to identify textures within the engine. It is expected that they are implemented within the games scope.

Member Function Documentation

addSingleTexture()

void TextureManager::addSingleTexture	(	Textures	texture,
		const char *	filePath )

Adds a single texture to the cache.

Parameters

texture	The texture identifier.
filePath	The file path to the texture file.

Exceptions

std::runtime_error

Is thrown if the texture could not be loaded correctly

This function loads the texture from the specified file and stores it in a cache.

addTextures()

void TextureManager::addTextures

(

const std::map< Textures, const char * > &

textures

)

Adds multiple textures to the cache.

Parameters

textures

A map of texture identifiers and corresponding file paths.

This function iterates over the provided map of textures and loads each texture using addSingleTexture. It allows for several textures to be added at once.

loadMapTileTexture()

SDL_Texture * TextureManager::loadMapTileTexture

(

const char *

path

)

Loads a map tile texture from the file system and caches it.

Parameters

path	The file path to the texture.

Returns

SDL_Texture* representing the map tile.

Exceptions

std::runtime_error

Is thrown if the texture could not be loaded correctly

This function checks if the map tile texture is already cached. If not, it loads the texture from the file system and stores it in the cache.

Todo

should not be usable for the developer and only be accessed by the map class

loadTexture()

SDL_Texture * TextureManager::loadTexture

(

Textures

texture

)

Loads a texture from the cache.

Parameters

texture

The texture identifier.

Returns

A pointer to the SDL_Texture if found, or nullptr if not found.

This function looks up a texture within the cache and returns the corresponding SDL_Texture*. If the texture is not found, it logs an error message and returns nullptr.
