engine.console Functions

Warning
The scope of applications for UnigineScript is limited to implementing materials-related logic (material expressions, scriptable materials, brush materials). Do not use UnigineScript as a language for application logic, please consider C#/C++ instead, as these APIs are the preferred ones. Availability of new Engine features in UnigineScipt (beyond its scope of applications) is not guaranteed, as the current level of support assumes only fixing critical issues.

Controls console-related parameters.

Adding Console Command with Several Arguments#

The Console class can be used to create custom user console commands with a different number of arguments. This section provides an example of how to create a custom console command with several arguments.

Prior Knowledge
It is supposed that you have already created an empty UnigineScript project by using UNIGINE SDK Browser.

In the example below, we perform the following actions:

  • Define and implement methods for console commands.
  • Add a new command.
1. Implementing Callback Function

In this example, we define 2 functions in the world script (unigine_project.usc file): one as a callback for a console command with no arguments and one for a console command with 1 argument.

Source code (UnigineScript)
// unigine_project.usc

// a script function to be executed for no arguments input
void console_action_callback() {
	log.message("first action! no arguments!\n");
}

// a script function to be executed for 1 argument input
void console_action_callback(string arg) {
	log.message("second action! the argument is: %s\n",arg);
}
2. Adding Custom Console Command

Add a custom command to the unigine_project.usc file by using engine.console.addCommand() function. By adding this code into init() function, the engine adds a new console command on world initialization.

Source code (UnigineScript)
// unigine_project.usc

/* ... */

int init() {
	// add a command
	engine.console.addCommand("console_action","my_command description","console_action_callback");
	
	return 1;
}

/* ... */
3. Running Sample

Run the project and open the console. Write recently created command to check the result:

Output
#if you write "console_action"
console_action
first action! no arguments!

#if you write "console_action arg"
console action arg
second action! the argument is: arg

To remove the added console command, use removeCommand() method.
