CS2: How to get crc-map code?

[NintyS]

How to get CRC code of map in CS2 version of the library?
The msgs2.CSVCMsg_ServerInfo don't have a GetMapCrc() function as I see

[dankotov]

@NintyS were you ever able to figure out?

[NintyS]

Nah, probably you can't. But I get from CS:GO the CRC codes and they works so for now I'm good.

var (
	Mirage   uint32 = 1936772555
	Anubis   uint32 = 3934213780
	Nuke     uint32 = 4081488007
	Inferno  uint32 = 3201302029
	Ancient  uint32 = 4262714479
	Overpass uint32 = 2863184063
	Vertigo  uint32 = 970160341
)

Understood! Thanks for the list. However, how do you get the map name from the demo to get the corresponding crc? header.MapName returning nil for me.

[NintyS]

Sorry for delay, I didn't get notification until I open mail. AFAIK header is deprecated / returns nothing because new header is different than old one.

This is my code:
`
var mapName string
var mapMetaData ex.Map

p.RegisterNetMessageHandler(func(msg *msgs2.CSVCMsg_ServerInfo) {

	var mapCode uint32 = 0

	if strings.Contains(msg.GetMapName(), "mirage") {
		mapCode = Mirage
	}

	if strings.Contains(msg.GetMapName(), "overpass") {
		mapCode = Overpass
	}

	if strings.Contains(msg.GetMapName(), "inferno") {
		mapCode = Inferno
	}

	if strings.Contains(msg.GetMapName(), "vertigo") {
		mapCode = Vertigo
	}

	if strings.Contains(msg.GetMapName(), "anubis") {
		mapCode = Anubis
	}

	if strings.Contains(msg.GetMapName(), "nuke") {
		mapCode = Nuke
	}

	if strings.Contains(msg.GetMapName(), "ancient") {
		mapCode = Ancient
	}

	mapMetaData = ex.GetMapMetadata(msg.GetMapName(), mapCode)

	fmt.Println(mapMetaData)

	mapName = msg.GetMapName()
})`

It's shit but for now this is only thing I can do I guess. Maybe I will post my repo with code as a example for people.

[dankotov]

Understood! Thanks for sharing

[dankotov]

Out of curiosity, is there any reason you dont do it like this?

var mapCodes = map[string]uint32{
	"de_mirage":   1936772555,
	"de_anubis":   3934213780,
	"de_nuke":     4081488007,
	"de_inferno":  3201302029,
	"de_ancient":  4262714479,
	"de_overpass": 2863184063,
	"de_vertigo":  970160341,
}

var mapMetadata ex.Map

p.RegisterNetMessageHandler(func(msg *msgs2.CSVCMsg_ServerInfo) {
	mapName := msg.GetMapName() // change if you want mapName to be available somewhere else as well
	mapMetadata = ex.GetMapMetadata(mapName, mapCodes[mapName])
})

[NintyS]

Yes, because I forgot that Key-Value dictionaries exists XD
