Call()

variable call(string function_name, variable arguments)

Calls a function, which name is provided as an argument.
Notice
The above expression is equivalent to this one: function_name(arguments).

Arguments

  • string function_name - Name of the function to call.
  • variable arguments - Function arguments.

Return value

Function execution result.

Examples

Source code (UnigineScript)
call("log.message","%d %s\n",13,"some text");

// the result is: 13 some text

variable call(int function_id, variable arguments)

Calls a function by its ID, which is almost as fast as the direct function call. In order to get this ID, use get_function().

Arguments

  • int function_id - ID of the function to call.
  • variable arguments - Function arguments.

Return value

Function execution result.

Examples

Source code (UnigineScript)
void foo(int a) {
	log.message("%d\n",a);
}

int id = get_function("foo",1);	
call(id,3);

// the result is: 3
If you need to call a user class method by its ID rather then as a static method, you can use the following:
Source code (UnigineScript)
class MyClass {
    
    void print_me() {
        log.message("MyClass::print_me() called\n");
    }
    
    void id_func(MyClass obj) {
        obj.print_me();
    }
};

MyClass m = new MyClass();
call(get_function("MyClass::id_func",1),m);

// the result is: MyClass::print_me() called
Also you can call the id_func() function as follows:
Source code (UnigineScript)
int id = get_function("MyClass::id_func",1);
m.call(id,m);

variable call(string function_name, variable array)

Calls a function, whose name is provided as an argument. The number of function arguments can vary.

Arguments

  • string function_name - Name of the function to call.
  • variable array - Function arguments. The number of function arguments can vary.

Return value

Function execution result.

Examples

Source code (UnigineScript)
int args[] = ("%s\n","hello world");
call("log.message",args);

// ouput: hello world

variable call(string method_name, variable arguments)

Calls methods of external or user-defined classes.

Arguments

  • string method_name - Name of the method to call.
  • variable arguments - Function arguments.

Return value

Function execution result.

Examples

Call methods of an external class:

Source code (UnigineScript)
File file = new File("test.cpp","rb");
log.message("%d %s\n",file.call("isOpened"),file.call("getName"));
file.call("close");	// same as file.close();
delete file;

// the output is: 1 test.cpp
Call a method of a user-defined class:
Source code (UnigineScript)
class Foo {
	void print(int a) {
		log.message("Foo::print(): %d\n",a);
	}
};
Foo foo = new Foo();
foo.print(1);
foo.call("print",2);

// Foo::print(): 1
// Foo::print(): 2
