vcmi/lib/BattleState.cpp
Michał W. Urbańczyk 046e54563c * fixed project files for RD configuration
* fixed crash when creature is casting Hypnosis (ie. exped Vampire Lords)
* fixed crash when creature is casting Cure before attack (ie. exped Unicorns)
* fixed crash when creature is summoning elemental (TODO fix it)
* fixed crash when doing a bonus system operation with a hero liberated from prison (ie. entering town or battle)
* fixed deadlock when StupidAI tried to assault the turrets
* fixed never ending siege when StupidAI has to use catapult (no more deadlocks on AI-AI siege)
* fixed deadlock when a hero received a level during another player's turn (ie. when he successfully defended)
* AI can win the game by defeating all enemies if there is a specific victory condition applying only to human players
* added options to help testing adventure map AI (--onlyAI, --autoSkip and --oneGoodAI).
* many minor changes
