Getting Started

ArmaRAMDb

Prerequisites

• Network access
• Minimum 4GB of RAM to get the benifits of RAMDb
• Minimum 1CPU Core

OS Compatibility

ArmaRAMDb is currently only compatible with Windows. Linux is planned for a future release.

Usage

1. Download the latest release from the Releases page.
2. Extract the zip file to your Arma 3 directory.
3. Create the init.sqf file in your mission folder and add the following code:

addMissionEventHandler ["ExtensionCallback", {
    params ["_name", "_function", "_data"];
    diag_log _this;
    if (_name isEqualTo "ArmaRAMDb") then {
        parseSimpleArray _data call (missionNamespace getVariable [_function, {
            hint "Function does not exist!"
        }]);
    };
}];

4. Create the initServer.sqf file in your mission folder and add the following code:

if (isServer || isDedicated) then {
    true spawn ramdb_db_fnc_init;
};

5. Implement data persistence using ArmaRAMDb:
   • To enable saving and loading data from ArmaRAMDb, you need to create the necessary functions.
   • Refer to the Add Task wiki page for detailed information on how to create tasks in ArmaRAMDb.
   • Utilize the ramdb_db_fnc_addTask function to add tasks to the ArmaRAMDb queue for saving and loading data.
   • Here's an example of how you can create a task to save data:

     IMPORTANT: All data must be encapsulated by brackets []

     ["hsetid", getPlayerUID player, "loadout", -1, [getUnitLoadout player]] call ramdb_db_fnc_addTask;
     

     
     This example adds a task to set the value of the field "loadout" in the hash player UID to the player's loadout.
   • To load data, you can create a task using the appropriate task type, such as "hgetall" or "hget":

     ["hgetid", getPlayerUID player, "loadout", -1, [], "myCallbackFunction", false, netId player] call ramdb_db_fnc_addTask;
     

     
     This example adds a task to retrieve all values from the hash player UID and pass the retrieved data to the "myCallbackFunction" for further processing.
   • Ensure that you provide the correct task type, key names, field names, and callback functions based on your specific data requirements. Please refer to the Task Types section below for more information on available task types and their corresponding data types.
   • Properly handle the retrieved data in the callback functions to utilize it effectively in your project.
     • I.e. implement public variables and waitUntil checks before proceeding onto the next task(s).

     // First Script or Function to execute `ramdb_db_fnc_addTask`
     value_ExampleDone = false;
     publicVariable "value_ExampleDone";
     ...
     
     // Callback function to process the retrieved data
     ...
     value_ExampleDone = true;
     publicVariable "value_ExampleDone";
     
     // Next Script or Function to execute `ramdb_db_fnc_addTask`
     waitUntil { value_ExampleDone };
     ...
     

By following these steps and leveraging the ramdb_db_fnc_addTask function, you can implement robust data persistence functionality using ArmaRAMDb in your Arma 3 project.
