Call()

WarningThe 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 UnigineScript (beyond its scope of applications) is not guaranteed, as the current level of support assumes only fixing critical issues.

Methods:

Name	Description View: Sort by:
call	Calls a function, which name is provided as an argument.

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
