I'm indexing coordinates around the map for a teleport plugin and i'm having trouble setting up the keyvalues retrieval. I wrote a simple test plugin to try and read the value at
locations > clocktower > emp > x
but i get this error:

KeyValues Error: RecursiveLoadFromBuffer: got EOF instead of keyname in file addons/sourcemod/teleportlocations.txt
locations, (*clocktower*), (*prime*),

PHP Code:

"locations"
{
    "clocktower"
    {
        "ct"
        {
            "x"    "-129"
            "y"    "5127"
            "z"    "-1390"
        }
        "emp"
        {
            "x"    "-3805"
            "y"    "-5324"
            "z"    "-1370"
        }
        "prime"
        {
            "x"    "-1125"
            "y"    "-45"
            "z"    "-1340"
        }
    }
} 


PHP Code:

public Action:CMD_TEST(client, args) {
    new value = GetCoord("emp", "x");
    PrintToChat(client, "%d", value);
}

GetCoord(const String:Location[], const String:Coord[]) {
    new value
    decl String:MapName[64];
    GetCurrentMap(MapName, sizeof(MapName));
    
    new Handle:kv = CreateKeyValues("locations");
    FileToKeyValues(kv, "addons/sourcemod/teleportlocations.txt");
    KvJumpToKey(kv, MapName, false);
    KvJumpToKey(kv, Location, false);
    value = KvGetNum(Handle:kv, Coord);
    CloseHandle(kv);
    return value;
}

I'm a bit rusty when it comes to the sp keyvalues api, but I think you need to jump down a level after you jump to the map key, using KvGotoFirstSubKey.

Just a comment, rather than storing x, y, and z separately, consider storing them as a Vector.

Having worked with KeyValues more recently, I believe you're correct.

Thanks for your help, both of you.

Now I've run into another problem. I want to list the names of the keys under the map names, but after following this thread:
https://forums.alliedmods.net/showthread.php?t=184725
my function lists the map names instead of the keys beneath it. It sounds like Leonardo got his function working, and I can't see what I'm really doing differently to break mine.

Just for clarification, if I'm on clocktower and I run this command, I want the console to read out:
ct
emp
prime
someotherlocation

PHP Code:

"Locations"
{
    "clocktower"
    {
        "ct"    "-129.0 5127.0 -1390"
        "emp"    "-3805.0 -5324.0 -1370.0"
        "prime" "50.0 -927.0 -1370.0"
        "someotherlocation" "1 2 3"
    }
    "downtown"
    {
        "ct"    "6438.0 -136.0 -3760.0"
        "emp"    "-5672.0 1.0 -3700"
        "prime"    "518.0 2.0 -3750"
    }
} 


PHP Code:

public Action:CMD_ListLocations(client, args) {
    decl String:MapName[64], String:key[64];
    GetCurrentMap(MapName, sizeof(MapName));
    
    new Handle:kv = CreateKeyValues("locations");
    FileToKeyValues(kv, "addons/sourcemod/teleportlocations.txt");
    KvJumpToKey(kv, MapName, false);
    KvGotoFirstSubKey(kv, false);
    
    if (GetCmdReplySource() == SM_REPLY_TO_CHAT) {
        PrintToChat(client, "[SM] See console for output.");
    }
    
    PrintToConsole(client, "Teleport locations on %s:", MapName);
    
    do {
        KvGetSectionName(kv, key, sizeof(key));
        PrintToConsole(client, "%s", key);
    } while (KvGotoNextKey(kv));

    CloseHandle(kv);
    return Plugin_Handled;
}

Nevermind, I figured it out. Be sure to check the bools in KvGotoFirstSubKey and KvGotoNextKey if you're reading this.
So the "while" part of the do-while loop above needed to be this instead:
while (KvGotoNextKey(kv, false));

A common idiom while reading KeyValues is to do this:

PHP Code:

if (!KvGotoFirstSubKey(kv, true))
{
    return; // or continue; if in a loop
}

do
{

} while (KvGotoNextKey(kv, true)); 


Note that the bool argument to both Kv functions should be identical.
