Missing player in TeamState.Members()

[CapekM]

Describe the bug I was parsing demofiles from HLTV and noticed that parser.GameState().TeamTerrorists().Members() does not return all players, but all players are in the parser.GameState().Participants().All(). When I looked into the func (ptcp participants) TeamMembers(team common.Team) there were only 9 participants, but the parser.GameState().Participants().All() is returning 13 players and all right ones are there. When I looked into the p.parser.GameState().Participants().Connected/Playing() there are the 9 players. I'm not sure if it's a problem with data or the parser, since I'm not much proficient with this library. Thanks for any reply.

To Reproduce For example:

• 1st map of https://www.hltv.org/matches/2368503/virtuspro-vs-spirit-betboom-dacha-2023
  • After 3rd round player mir
• Both maps of https://www.hltv.org/matches/2368419/space-vs-alternate-attax-cct-2023-online-finals-5
  • 1st map after 5th round player fozil
  • 2nd map after 4th round player PerX

Library version v4.0.0

There seems to be an issue with disconnecting and reconnecting. When "mir" disconnects and later reconnects he is still marked as disconnected

Round finished: winnerSide=T  ; team_len=5:5
Round finished: winnerSide=T  ; team_len=5:5
Round finished: winnerSide=T  ; team_len=5:5
player mir disconnected
player mir connected
Round finished: winnerSide=T  ; team_len=5:4
Round finished: winnerSide=T  ; team_len=5:4

Probably there should be some additional handling for this situation in the playerConnect method analogically to the disconnecting https://github.com/markus-wa/demoinfocs-golang/blob/5543f4b8241a8a525bfa9ebe2ece95b0323746fb/pkg/demoinfocs/game_events.go#L655-L662 inside the playerDisconnect method?

This is related to #494; I believe the problem is that we should switch to track players using the CCSTeam.m_aPlayers.00xx prop. From here, we can correctly keep track of players moving in and out of teams like so:

The most basic version of this is:

teamPlayers := make([]*common.Player, 64)

for i := 0; i < 64; i++ {
	i := i
	slot := fmt.Sprintf("m_aPlayers.%04d", i)
	entity.Property(slot).OnUpdate(func(pv st.PropertyValue) {
		var player *common.Player
		if pv.Any != nil {
			player = p.gameState.playersByEntityID[entityIDFromHandle(pv.S2UInt64(), true)]
		}
		teamPlayers[i] = player

		fmt.Printf("%v switched to %s\n", player, team)
	})
}

I have something like the above hacky version of this working locally, but I think we might need to consult @markus-wa or @akiver to decide how to do this properly. Right now I can't see a way to do this without a medium-sized overhaul of the team-related code.

Sorry I'm currently a bit slow at getting back on issues - this definitely seems like an important thing to fix. I'm not sure about m_aPlayers - what about using m_iTeamNum on the player pawns?

I don't know how quickly I'll be able to get to this so MRs are very welcome. Happy to go with the m_aPlayers path if that seems to be the most reliable

This looks relevant: https://github.com/akiver/cs-demo-analyzer/blob/6c642144c19a40277e3690a3d6fc42e313f8752e/pkg/api/ebot.go#L71

could you try with this branch please? https://github.com/markus-wa/demoinfocs-golang/pull/499

I will be closing this for now, feel free to reopen if the issue persists with v4.0.2
