Respawns...

I've noticed (especially on ducati hunt-the-rabbit) That the respawns are really, really, really screwed. I cannot count how many times i've been respawned right in front of a bullet, or infront of the rabbit. Its down right annoying and salvation costing. has the respawn code been messed with or is this a server thing?

I have noticed this alot also. Did the code get changed to make the respawn more random? I think it might have. Did the respawn code from previous versions get deleted? On all the previous versions there was code to stop the bad respawn from happening.

The server now decides where you spawn. I think the code is just buggy right now.

I don't think server side spaws were implemented, because the server dosn't have a full game state yet, it dosn't know where shots are. I will find out tho.

I belive this is the code from the client used to grab a new spawn location from the server.
First, the restart command in playing.cxx
Code: Select all
static std::string cmdRestart(const std::string&, const CommandManager::ArgList& args)
{
if (args.size() != 0)
return "usage: restart";
if (myTank != NULL)
if (!gameOver && (myTank->getTeam() != ObserverTeam) && !myTank->isAlive() && !myTank->isExploding())
serverLink->sendAlive();
return std::string();
}
It then calls sendAlive() in serverlink.cxx
Code: Select all
void ServerLink::sendAlive()
{
send(MsgAlive, 0, NULL);
}
Then back in playing.cxx, in handleServerMessage(...), it recieves the spawn message.
Code: Select all
case MsgAlive: {
PlayerId id;
float pos[3], forward;
msg = nboUnpackUByte(msg, id);
msg = nboUnpackVector(msg, pos);
msg = nboUnpackFloat(msg, forward);
int playerIndex = lookupPlayerIndex(id);
if ((playerIndex >= 0) || (playerIndex == -2)) {
static const float zero[3] = { 0.0f, 0.0f, 0.0f };
Player* tank = getPlayerByIndex(playerIndex);
if (tank == myTank) {
wasRabbit = tank->getTeam() == RabbitTeam;
myTank->restart(pos, forward);
firstLife = false;
mainWindow->warpMouse();
hud->setAltitudeTape(World::getWorld()->allowJumping());
} else if (tank->getPlayerType() == ComputerPlayer) {
for (int r = 0; r < numRobots; r++) {
if (robots[r]->getId() == playerIndex) {
robots[r]->restart(pos,forward);
setRobotTarget(robots[r]);
break;
}
}
}
tank->setStatus(PlayerState::Alive);
tank->move(pos, forward);
tank->setVelocity(zero);
tank->setAngularVelocity(0.0f);
tank->setDeadReckoning();
if (tank==myTank)
playLocalSound(SFX_POP);
else
playWorldSound(SFX_POP, pos[0], pos[1], pos[2], true);
}
break;
}
I'll have to look at the server code to see what it does.

The spawn code in the server is located at bzfs.cxx:2852. The spawn location calculation was moved to the server to give the server more control over the game and to prevent cheating (some people hacked their client to spawn on top of GM flags etc). The current code does not do a very good job of finding a safe place for the tank, but it can (will) be improved in later server versions without breaking the protocol and without requiring a client upgrade.

since the server does not fully track shots this would make the spaws very difrent from the old way, but you are asured that everyone spawns the same way.

Ok, thanks guys! As long as there is a valid reason I am fine with it and that is definately a valid reason.

In front of my shots...problem number two, on xmission and on others server using the command -tk I'll be killed "Players who kill teammates die".

Exactly!
on ducati hunt the rabbit. I'm more scared of my teammates then the Rabbit!
IF the tk option is on. you die and lose 2 points, not just 1.

someone should get to coding up a proper server state then.

Server ops can mitigate the problem a little by adding -sb to their bzfs command lines, which means "spawn on buildings". In this way sometimes tanks spawn on buildings, which should be less dangerous than on the ground. But yes, the currently algorithm is completely random, now.

It was a bug in the 1.10.0 server, and was fixed in 1.10.2.

Sorry guys
Current CVS has a slight improvement on this. I am not sure how good it works in practice. It's probably slightly worse with respect to enemy tanks than the odl spawns and it does not respect shots at all.
Ducati 1.10 servers are running this code.

I see in the task lists on sourceforge that a full client side state is not planed untill 2.0, a full 2 more releases away. Is that really how long it will take before there can be spwans of the the same type that the last release had?

Before it was far away (in a safe position) and now you respawn totally between the tanks (fighting) or close to a SW (3 times in a row on xmission).
