C++ CStr::ToUInt方法代码示例

/*
 * Command line options for autostart (keep synchronized with binaries/system/readme.txt):
 *
 * -autostart="TYPEDIR/MAPNAME"         enables autostart and sets MAPNAME; TYPEDIR is skirmishes, scenarios, or random
 * -autostart-ai=PLAYER:AI              sets the AI for PLAYER (e.g. 2:petra)
 * -autostart-aidiff=PLAYER:DIFF        sets the DIFFiculty of PLAYER's AI (0: sandbox, 5: very hard)
 * -autostart-civ=PLAYER:CIV            sets PLAYER's civilisation to CIV (skirmish and random maps only)
 * -autostart-aiseed=AISEED             sets the seed used for the AI random generator (default 0, use -1 for random)
 * Multiplayer:
 * -autostart-playername=NAME		sets local player NAME (default 'anonymous')
 * -autostart-host                      sets multiplayer host mode
 * -autostart-host-players=NUMBER       sets NUMBER of human players for multiplayer game (default 2)
 * -autostart-client=IP                 sets multiplayer client to join host at given IP address
 * Random maps only:
 * -autostart-seed=SEED                 sets random map SEED value (default 0, use -1 for random)
 * -autostart-size=TILES                sets random map size in TILES (default 192)
 * -autostart-players=NUMBER            sets NUMBER of players on random map (default 2)
 *
 * Examples:
 * 1) "Bob" will host a 2 player game on the Arcadia map:
 * -autostart="scenarios/Arcadia 02" -autostart-host -autostart-host-players=2 -autostart-playername="Bob"
 * 2) Load Alpine Lakes random map with random seed, 2 players (Athens and Britons), and player 2 is PetraBot:
 * -autostart="random/alpine_lakes" -autostart-seed=-1 -autostart-players=2 -autostart-civ=1:athen -autostart-civ=2:brit -autostart-ai=2:petra
