Thanks for the updates. I'm getting this exception if I click too early in the graph area:

Changing AIGamePlayer.java line 312 to:

if (turn > turnsForGame || turn < 0 || turnsForGame <= 0)

fixes it.

Thanks. Fix included and uploaded.

Now on the Combat screen I'm getting this crash during playback:

The first error is more or less a race condition. This is fixed, but should have been quite rare anyway. It also can be safely ignored for the most part. However i have applied a fix. So it shouldn't happen again.

I could not produce the second error even when using old save games. I have put an extra bounds check anyway that should fix the problem.

A new version is uploaded.

Thanks for the bugfixes/bugs/comments.

There's something odd about those big ship arrows. On the first move they appear in the middle of the source planet instead of just outside like they used to. Also they're a little too big. Try using the scaling factors that the javascript visualizer uses if you're not already.

[delt0r]

the arrows are not perfect. I tried lots of different ways to scale. I currently use a log+constant scaling. But it was just "good enough", i didn't look up the js player so i don't know what its using. I am open to suggestions. As for "position" the position is the tip of the arrow. Big arrows will tend to have a back part behind the center of the planet.

Also for fleet position, its odd. But by design. I wanted it too match the game state accuratly. The problem with this is that fleets get a "free" turn and they have moved one turn on the turn they appear. This is the game engine design. So they appear basically one turn into their n turn trip.

[Ice_Harley]

Does anybody have "determinism" problem with this engine?
I mean, when i play same games with same bot on same map - i have different results.
For example, i am testing my bot against DoNothingBot (he just sends "go" every turn) on map1.
First game i win in 122 turns, having 2546 ships at the end.
Second game i win in 125 turns, having 2720 ships.
And so on... Different results each time. I didn't use random. I am playing as player 1 every time.
Ok, this can be still my bot fault, but playing on PlayGame.jar doesn't have this problem. It gives me every time same results.

Ice_Harley: Do you use random()? Or do you use sorting?
Sorting can produce different results if the key is not unique.
You can solve this by appending a unique part (i.e. planet_id).
The different results may be because JBotManager presents fleets in a different order.

[delt0r]

It was at my end. In that the fleet order could be different. This does not affect any of my bots so i didn't notice. This is now corrected, as i now use a LinkedHashMap to collapse multiple orders from the same source/destination in the same turn.

I have adjusted the sizing of the fleets a little. It turns out that my scaling method is the same. But there parameters are not directly comparable.
