Just start playing and I am impressed with both AI and UI.
Reports are for 1.37 MCTS-8

Vampiric Link and Spirt Link both have
'Enchant creature. Whenever enchanted creature deals damage, you gain that much life.'
With Vampiric Link, to use on opponents creature, must deselect 'Remove unusual target choices'

Inkmoth Nexus tapped itself to pay for it's ability G1.txt
played Cruel Edict when I have no creature to sacrifice G2.txt
Bloodthrone vampire is sacrificed to give itself +2/+2 when blocking with it G3.txt
Will re-attach equipment to same creature G4.txt

So when I start a game, I can never see my opening hand until after the computers first turn. It is at the draw step that the hand is revealed on my second turn. after that everything works fine. I have tried uninstalling and reinstalling yet the problem persists. Please help and thank you

Crash at first turn of duel

Just start playing and I am impressed with both AI and UI. Reports are for 1.37 MCTS-8

Welcome to Magarena, Nightchill, thanks for the compliments and feedback. Including the game logs and mentioning which version/AI you were playing against is very helpful.

Vampiric Link and Spirit Link both have
'Enchant creature. Whenever enchanted creature deals damage, you gain that much life.'
With Vampiric Link, to use on opponents creature, must deselect 'Remove unusual target choices'

The problem is that Vampiric Link was using a different targetting hint, fixed to use the same targetting hint as Spirit Link.

Inkmoth Nexus tapped itself to pay for it's ability

Fixed by requiring the AI to have open before playing the second ability.

played Cruel Edict when I have no creature to sacrifice

Code: Select all

 MCTS cheat=false index=1 life=20 time=8003 sims=1074                                                                                                                                         
   [66/45/?] (pass)                                                                                                                                                                           
 * [80/1029/?] (Cruel Edict)


From the attached log, the AI thinks that playing Cruel Edict gives it an 80% chance of winning vs the 66% for passing. An interesting fact about the MCTS AI is that it only cares about the change of winning, so sometimes it might make weird moves. Right now, we have no good way to fix this. Did the AI win in the end?

Bloodthrone vampire is sacrificed to give itself +2/+2 when blocking with it

Code: Select all

 MCTS cheat=false index=1 life=18 time=8003 sims=1883                                                                                                                                         
   [3/933/?] (pass)                                                                                                                                                                           
 * [3/950/?] (Bloodthrone Vampire)


In this case, the AI thinks it is losing, both choices only give it a 3% chance of winning. Hence it simply picked one with greater number of simulations (950 simulations for activating Bloodthrone Vampire vs 933 for passing). Would passing have allowed Bloodthrone Vampire to destroy the attacker. Did the AI lose in the end?

Will re-attach equipment to same creature

Fixed by requiring the target of equip to be different from the currently equipped permanent.

Thanks for the quick reply and detailed explanations.

I can not remember who won, but AI would not have been able to destroy attacker by passing (not activating). In future I will post log for complete game so you can see what happens afterwards.

Fixed by requiring the target of equip to be different from the currently equipped permanent.

Have also seen it move equipment from creature A to creature B then back again to A in same phase but did not keep log.

Another crash

The AI cast Rally the Forces when I was attacking with Bomber Corps, which was my only creature. The AI had no creatures. The result was that the AI took 2 damage instead of 1.

Here's the log. I was playing with MCTS-4. I can see that the AI had Rally the Forces in hand already on its own turn, but there the choice was to pass on it.

Hi blade22031, welcome to Magarena. Could you see your opening hand if you start second in the turn? It will be helpful if you could send a screenshot showing the missing hand to magarena@googlegroups.com or post it here. Thanks!

I've seen that before as well, not sure how this can be fixed. Some moves don't affect the chance of winning a game, such as moving an equipment off a permanent and back when the AI has excess mana. The MCTS AI already prefers winning games to end early and losing games to end late. The second condition also makes the MCTS AI play lots of useless moves to try and delay the lose, which is an unfortunate side effect.

Game crushed.

Thanks for your report. Been fighting this bug on and off for a while, thought we finally solved it, looks like it is back.
