More informations: now your lablgtk2 does not need to be compiled with gtkglarea anymore. Only Debian and Ubuntu seemed to be doing that.
Fixed major bug: when winning a passing shot, computer would believe he had won two balls, and would update his tactics accordingly. On the log run, he would wrongly prefer not to take the net.
Fixed minor bug: when human wins with a volee and computer is close to the net, computer would wrongly believe he had lost a ball taking the net, and update tactics.
fixed major bug that prevented the game to work on fast computers (player would not serve).
AI: the computer is now more forgiving under net.
players are now slower. Therefore, shots which are close to the line pay more; in addition, it is now reasonably easy to place a killing diagonal (previously it wasn't). Overall, this makes the game more realistic;
increased the vertical sprint speed;
decreased parabola visibility;
tuned bounce speed on all surfaces;
made dropshots and drop volleys easier;
better logic in choosing between "approaching attack" and "attack with power shot";
better logic choosing a volee: computer now plays an approaching volee when he is far from the net;
computer now approaches the net with a slower shot, in order to have more time to reach the net;
computer tries to get closer to the net than it did before, in order to play a stronger volee;
computer's passing shot is not so low and precise as it was before;
several other improvements.
Fixed bug in AI: when your service went out, computer would believe to have won a ball by not attacking, and would update his tactic accordingly.
Control gameplay: new logic to prevent dropshot from being too easy.
AI: the computer-driven player uses more sprint to get back to center.
Major graphics: computer now moves towards the ball even when he knows he can't reach it, or when it is going out. This way you don't know you won the point until the very last moment. This increases realism and was a requested feature.
Major AI: computer now sprints to get back to center when he is very decentered horizontally. This affects gameplay, because moving the computer with a short diagonal and then place a killing down-the-line is not so easy anymore.
Fixed rare crash (human player unable to create a suitable initial aim).
AI: the computer player would favour a volee close to the net even though he did not want to take the net at that time, and he was close to the baseline.
