|
|
*
|
|
* Stratagus Game Launcher is C code for generating launcher for any Stratagus game.
|
|
* Game launcher for concrete game check if game data exists in default Stratagus
|
|
* location and spawn Stratagus process with correct game data location. If does not
|
|
* exist it show GUI or console error message.
|
|
*
|
|
* Before including this header, you need to define:
|
|
*
|
|
* ::GAME_NAME
|
|
*
|
|
* ::GAME_CD
|
|
*
|
|
* ::GAME_CD_FILE_PATTERNS

*
|
|
* ::EXTRACTOR_TOOL
|
|
*
|
|
* ::EXTRACTOR_ARGS

|
*
|
|
* On Non Windows system you need to specify also paths:
|
|
*
|
|
* ::DATA_PATH
|
|
*
|
|
* ::SCRIPTS_PATH
|
|
*
|
|
* ::STRATAGUS_BIN
|
|
*
|
|
* On Windows paths are reading from InstallLocation key in Uninstall section:
|
|
* Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\Stratagus
|
|
*
|
|
* Example use of code:
|
|
*
|
|
* @code
|
|
*
|
|
* #define GAME_NAME "My Game Name"
