The game uses a probability matrix to calculate the probabilities the size of this matrix depends on the number of hitpoints the units have. When there are units with a huge amount of hitpoints this matrix will require a lot of memory, which might be quite slow due to swapping. Also the amount of calculations can cause a delay (berserk has to calculate a maximum of thirty rounds of combat). The current way works properly for the mainline content. Addons with extreme number of hitpoints (>1000) might get into problems. We had reports of people running out of memory due to huge amount of hitpoints due to size of the matrix and the amount of memory that required. An idea to limit the number of hitpoints to 1000 wasn't well received even after explaining the out of memory problem [1]. > Ideally, Wesnoth's CTK/CTBK calculator should not take this long to > return results.

Since the current way works properly for mainline content and the problem has been brought to the attention of addon developers we won't fix this problem in the foreseeable future. [1] http://forum.wesnoth.org/viewtopic.php?f=8&t=15761 Regards, Mark de Wever (Wesnoth developer) The current way works properly for the intended scope; units with not more than 100 hitpoints. Outside this scope it will get worse, but mainline has almost no units with more than 100 hitpoints.a -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
