# ramdb_db_fnc_hashGetId
|
|
|
|
## Description
|
|
Retrieves the value of a specific field from a hash table identified by its key. This function allows targeted access to individual fields within a specific hash table, making it ideal for accessing particular attributes of player or entity data. The retrieved data is returned through a callback function.
|
|
|
|
## Syntax
|
|
```sqf
|
|
[_key, _keyField, _function, _call, _netId] call ramdb_db_fnc_hashGetId
|
|
```
|
|
|
|
## Parameters
|
|
| Parameter | Type | Description | Default |
|
|
|-------------|---------|------------------------------------------------------------|---------|
|
|
| `_key` | String | Identifier of the hash table | "" |
|
|
| `_keyField` | String | Name of the field in the hash to retrieve | "" |
|
|
| `_function` | String | Name of the function to receive the retrieved data | "" |
|
|
| `_call` | Boolean | Whether to call the function directly (true) or spawn (false) | false |
|
|
| `_netId` | String | (Optional) NetID of the player to receive the data | "" |
|
|
|
|
## Return Value
|
|
None. The retrieved data is passed to the specified callback function asynchronously.
|
|
|
|
## Examples
|
|
### Retrieve a player's loadout field:
|
|
```sqf
|
|
[getPlayerUID player, "loadout", "ramdb_db_fnc_test"] call ramdb_db_fnc_hashGetId;
|
|
```
|
|
|
|
### Retrieve a specific vehicle property with synchronous callback:
|
|
```sqf
|
|
["vehicle_123", "fuel", "ramdb_db_fnc_processFuelData", true] call ramdb_db_fnc_hashGetId;
|
|
```
|
|
|
|
### Retrieve data and send it to a specific client:
|
|
```sqf
|
|
[getPlayerUID player, "stats", "ramdb_db_fnc_test", false, netId player] remoteExecCall ["ramdb_db_fnc_hashGetId", 2, false];
|
|
```
|
|
|
|
## Notes
|
|
- Retrieves a single field value from a specific hash table
|
|
- All three primary parameters (key, keyField, and function) are required and validated
|
|
- The data is retrieved asynchronously through the extension's callback system
|
|
- When a netId is provided, the data is sent to that specific client
|
|
- The `_call` parameter determines whether the function is called directly (synchronous) or spawned (asynchronous)
|
|
- This function targets both a specific hash table (`_key`) and a specific field (`_keyField`)
|
|
- More efficient than retrieving all hash fields when only one is needed
|
|
- Player UIDs are commonly used as keys to store player-specific data
|
|
- All operations are logged for debugging purposes
|
