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 unigine_project.cpp file: one as a callback for a console command with no arguments and one for a console command with 1 argument.
Source code (C#)
// unigine_project.cpp
// 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.cpp 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 (C++)
// unigine_project.cpp
/* ... */
int init() {
// add a command
engine.console.addCommand("console_action","my_command description","my_command_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: argTo remove the added console command, use removeCommand() method.
