[ H3LP ] Parsing BSP File

Hello. I am trying to parse a bsp file to get the keys and values of each entity, but ti doesn't seem to work well. No text is parsed.

PHP Code:


		
			
stock int strtok(const char[] szText, char[] szLeft, const int iLeftLen, char[] szRight, const int iRightLen, const char[] szToken, const int iTrimSpaces = 0) // from max_utils.inc
{
    int iPosLen = 0;
    
    iPosLen = StrContains(szText, szToken);
    
    if(!iPosLen)
        return 0;
    
    SplitString(szText, szToken, szLeft, iLeftLen);
    
    strcopy(szRight, iRightLen, szText[iPosLen + strlen(szToken)]);
    
    if(iTrimSpaces)
    {
        TrimString(szLeft);
        TrimString(szRight);
    }
    
    return strlen(szText);
}

void ParseEntities()
{
    char szMapName[128], szMapPath[512], szFileLine[2048];
    int iEntID = START_ENTITY;
    
    GetCurrentMap(szMapName, charsmax(szMapName));
    
    FormatEx(szMapPath, charsmax(szMapPath), "maps/%s.bsp", szMapName);
    
    Handle hFile = OpenFile(szMapPath, "r");
    
    if(hFile == INVALID_HANDLE)
    {
        LogError("Error parsing map '%s'!", szMapName);
        
        return;
    }
    
    while(!IsEndOfFile(hFile) && ReadFileLine(hFile, szFileLine, charsmax(szFileLine)))
    {
        if(strlen(szFileLine) == 0)
            continue;
        
        if(StrContains(szFileLine, "\"classname\"") != -1)
        {
            if(StrContains(szFileLine, "\"hammerid\"") != -1) // on Fortress Forever hammerid doesn't exist
                continue;
            
            while(!IsEndOfFile(hFile) && ReadFileLine(hFile, szFileLine, charsmax(szFileLine)))
            {
                if(strlen(szFileLine) == 0)
                    continue;
                
                if(szFileLine[0] != '"' && szFileLine[0] != '{' && szFileLine[0] != '}')
                    break;
                
                if(iEntID == START_ENTITY)
                    PrintToServer(szFileLine);
                
                if(!IsArrayValid(g_aEntVars[iEntID]))
                    g_aEntVars[iEntID] = CreateArray(g_iArrayLen, g_iArraySize);
                
                char szLeft[128], szRight[128], szText[256];
                strtok(szFileLine, szLeft, charsmax(szLeft), szRight, charsmax(szRight), " ");
                
                StripQuotes(szLeft);
                StripQuotes(szRight);
                
                FormatEx(szText, charsmax(szText), "%s*%s", szLeft, szRight);
                
                PushArrayString(g_aEntVars[iEntID], szText);
                
                // DEBUG
                if(iEntID == START_ENTITY)
                    PrintToServer(szText);
                
                if(szFileLine[0] == '}')
                    iEntID++;
            }
            
            break;
        }
    }
    
    CloseHandle(hFile);
}

Re: [ H3LP ] Parsing BSP File

The OnLevelInit provides the extracted entity lump for the current map, you can load it as KeyValues.

PHP Code:


		
			
Action OnLevelInit(const char[] szMapName, char szMapEntities[2097152])
{
    // ?
}

How would I do that exactly?
Is szMapEntities the char that holds the keys and values for each entity?

Yes.

I did that for a test, and it doesn't seem to work.

PHP Code:


		
			
public Action OnLevelInit(const char[] szMapName, char szMapEntities[2097152])
{
    if(!StrEqual(szMapName, "ff_xpress_b1", true))
        return Plugin_Continue;
    
    char szMapPath[160];
    
    FormatEx(szMapPath, charsmax(szMapPath), "%s-dump.txt", szMapName);
    
    Handle hFile = OpenFile(szMapPath, "w");
    
    WriteFileString(hFile, szMapEntities, false);
    
    CloseHandle(hFile);
    
    return Plugin_Continue;
}

It's like the forward isn't called and I have #include <sdkhooks>
And I made it to only dump if the map is ff_xpress_b1.

Apparently berni said somewhere in the forum that it doesn't work (OnLevelInit forward), and that was sometimes in 2011.
Perhaps it just doesn't work on Fortress Forever and maybe other source games.
Seems to work fine on TF2 from what I read (forum posts from 2014).

Can the forward be fixed?

Edit: I got it to work with #pragma dynamic 2097152
