Ok there is nothing stopping you in 75b2 from playing gundam.
However, I get tired of answering this question so I am making a thread to copy-paste each time someone asks.
There was a patch request to allow for a spherical aiming in spring. The old way it worked was a circle that went infinitely upwards(a cylinder). However, there was a mess up and the spherical aiming was applied to all of spring in 75b2. This means that in gundam a high flying aircraft cannot be targeted by most weapons.
In many other projects the aircraft fly lower to the ground and thus can be targeted easily. However gundam is not the case.
So what I have is an inability to say, shoot down transports or the com. Now there is a fix I released that fixes the spherical aiming. However, the tag breaks downward aiming.
So you can play gundam but it will not play right in this current release 75b2.
Questions I hear frequently:
Is there a fix for it?
yes in the svn it works right last I checked.
So this is why you do not play gundam right now?
Yes, believe me, I have not been able to play gundam online for months now and it is very annoying.
