I started studying SourcePawn and I am having some issues:

1.

There are global variables: MAX_NAME_LENGTH, MaxClients, MAX_TARGET_LENGTH, MAXPLAYERS .. What is more? Where is their list?

2.

decl string:weapon[32];
GetClientWeapon(client, weapon, sizeof(weapon));

It's not very convenient for me because always need to specify the size of the string. Is there a list of recommended values for certain rows? For example, player_say, "text" - what value? Etc.

3.

I'm already tired of the error when compiling: "Warning 213: tag mismatch" (although the script works)

PHP Code:

#include <sourcemod>

public OnPluginStart()
{
    HookEvent("player_say", PlayerSay);
}

public Action:PlayerSay(Handle:event, const String:name[], bool:dontBroadcast)
{
    new client = GetClientOfUserId(GetEventInt(event, "userid"));
    new string:msg[128];
    GetEventString(event, "text", msg, sizeof(msg));
    if (StrEqual(msg, "1")) {
        decl string:weapon[32];
        GetClientWeapon(client, weapon, sizeof(weapon));
        PrintToChatAll("%s", weapon);
    }
}

When you need to do so: new Handle:var; ?

PHP Code:

#include <sourcemod> 

public OnPluginStart() 
{ 
    HookEvent("player_say", PlayerSay); 
} 

public Action:PlayerSay(Handle:event, const String:name[], bool:dontBroadcast) 
{ 
    new client = GetClientOfUserId(GetEventInt(event, "userid")); 
    new String:msg[128]; 
    GetEventString(event, "text", msg, sizeof(msg)); 
    if (StrEqual(msg, "1")) { 
        decl String:weapon[32]; 
        GetClientWeapon(client, weapon, sizeof(weapon)); 
        PrintToChatAll("%s", weapon); 
    } 
} 


You must specify type of the variable correctly (string and String - different)

Thanks, I understand. How about the other issues? And one more thing that bothers me. Array stores the data of one type, but what if I need to store multiple values for the players (as a dictionary in Python)

In python this is simple:

mydict = {} client_index = 1 mydict[client_index] = {'name': 'Jon', 'years': 5} mydict[client_index]['name'] // Jon mydict[client_index]['years'] // 5

How to do the same in SourcePawn, it's unclear to me.

The globals that exist depend entirely on which .inc files you have loaded. The default, sourcemod.inc, loads a bunch of additional inc files.

The API documentation usually lists the globals for each inc. file when you click on it in the left list, but sometimes you have to click the File link near the upper-right to see them.

Some strings have recommended sizes, but most don't. For example, MAX_NAME_LENGTH is used if you're getting a player's name via GetClientName

Handles are a type-safe handle to data on the C++ side (see: SourceMod Extensions). Usually, the API documentation tells you which functions return a handle. Passing the wrong type of handle to a native will throw an error at runtime.

The Wiki talks about the types of Handles, although last time I checked, it was missing one or two.

As for dictionaries, Pawn doesn't really support them. There are two ways to fake them (more or less). One is to (ab)use enums. The other is to use an adt_array of adt_tries.

Thanks, I'll experiment.

As I know, u can't store multiple values with a different type in one array.

You can, however, with a Trie.

A Trie can be used as a simple-man's object by having differently named elements of different types.

PHP Code:

#include <sourcemod>

new var[MAXPLAYERS + 1];

public OnPluginStart()
{
    HookEvent("player_spawn", PlayerSpawn);
}

public Action:PlayerSpawn(Handle:event, const String:name[], bool:dontBroadcast)
{
    new client = GetClientOfUserId(GetEventInt(event, "userid"));
    if (GetClientTeam(client) > 1) {
        var[client] += 1;
        PrintToChat(client, "spawns = %d", var[client]);
    }
}

public OnClientPutInServer(client)
{
    var[client] = 0;
} 


new var[MAXPLAYERS + 1]; - If my server is 10 slots, We get 55 unwanted cells. It would be easier new var[MaxClients + 1];. I understand this is due to the fact that MaxClients is only available after OnPluginStart(). From here I have a question: "Is it possible to create global variables within functions?"

Python so simple in comparison with SourcePawn, there is simply:

PHP Code:

def myfunc():
    global var
    var = 1 


[berni]

You can use the "static" keyword, you can use MaxClients with it:

PHP Code:

static var[MaxClients+1]; 


If you need to access the variable in different functions you could use an ADT array.

Why PrintToChat sends the same message twice? (and PrintToChatAll). And I have not found the normal commands to work with indices of objects. For example, I need to remove all weapons from the ground. Or get a list of indexes of certain objects.

In Eventscripts it this way:

es.createentityindexlist('weapon_awp')

I've heard that SourceMod more features, but I still do not feel this.
