Working with Console

Calling a Console Command from Code#

To call a console command from the code, you should call the run() function.

Source code (C#)

// For example, to show messages:
Console.Run("show_messages 1");

Console commands (regardless of whether they were typed in the console or called from the code) cannot not be executed in the middle of the frame. Instead, they are executed in the beginning of the next frame not to interrupt the current rendering process and physics calculations.

Creating a Console Command#

Implement a callback for a console command and a method for an action performed on the console command call. Both methods should be implemented as AppWorldLogic instance methods.
Notice
If you want the console command to take more than one argument, you need to implement a separate method per each number of arguments.
Get the console instance (which has a singleton implementation) and call addCommand() to add a new command.

In the example below, a new command takes no arguments or one argument. For this, three methods are implemented in the AppWorldLogic.cs file:

choose_command() calls the appropriate method for the console command.
action_no_args() is called if there are no arguments.
action_one_arg() is called if one argument has been passed.

Source code (C#)

// AppWorldLogic.cs

using namespace Unigine;

public static void choose_command(int argc, string[] argv)
{	
	// print all console command arguments
	// note: the first element of argv is the name of console command
	for (int i = 1; i < argc; i++) {
		Log.Message("arg[{0}]: {1}\n", i, argv[i]);
	}
	// if no arguments is specified
	if (argc == 1) {
		action_no_args();
	}
	// if one argument is specified
	else if (argc == 2) {
		 action_one_arg(argv[1]);
	}
	// for more arguments:
	//else if (...) {
		//	// etc
	//}
}

// print the message into console, if there are no arguments
public static void action_no_args()
{
	Log.Message("first action! no arguments!\n");
}

// print the message into console, if an argument was passed
public static void action_one_arg(string s)
{
	Log.Message("second action! the argument is:{0} \n", s);
}

 public override bool Init()
{
	// get the existing singleton Console instance and add a command
	Console.AddCommand("console_action", "Performs custom console action", choose_command);

	return true;
}

Arguments argc and argv are used to get the arguments count and arguments vector.

Notice
					The first element of argv always keeps the name of a console command. Thus, argc is always >= 1. To get the first passed argument, you should use argv[1].
				

To check the result, run the added command:

Source code

Unigine~# console_command
first action! no arguments!

Unigine~# console_command arg
arg[1]: arg
second action! the argument is: arg

Creating a Console Variable#

Notice

C# API doesn't provide the ability to add console variables.

Disabling Console#

To disable console (for example, for an application production version), you need to call setLock().

Source code (C#)

// disable the console
Console.Lock = 1;
