Unigine::Input Class
| Header: | #include <UnigineInput.h> |
The Input class contains functions for simple manual handling of user inputs using a keyboard, a mouse or a gamepad.
This class represents an engine's singleton.

Usage Examples#
The following example shows a way to move and rotate a node by using the Input class:
Source code (C++)
#include "AppWorldLogic.h"
#include <UnigineInput.h>
#include <UnigineConsole.h>
#include <UnigineGame.h>
#include <UniginePrimitives.h>
using namespace Unigine;
using namespace Math;
NodePtr box;
float move_speed = 1.0f;
float turn_speed = 30.0f;
int AppWorldLogic::init()
{
box = Primitives::createBox(vec3_one);
return 1;
}
int AppWorldLogic::update()
{
if (Console::isActive())
return 1;
if (Input::isKeyPressed(Input::KEY_UP) || Input::isKeyPressed(Input::KEY_W))
box->translate(Vec3_forward * move_speed * Game::getIFps());
if (Input::isKeyPressed(Input::KEY_DOWN) || Input::isKeyPressed(Input::KEY_S))
box->translate(Vec3_back * move_speed * Game::getIFps());
if (Input::isKeyPressed(Input::KEY_LEFT) || Input::isKeyPressed(Input::KEY_A))
box->rotate(0.0f, 0.0f, turn_speed * Game::getIFps());
if (Input::isKeyPressed(Input::KEY_RIGHT) || Input::isKeyPressed(Input::KEY_D))
box->rotate(0.0f, 0.0f, -turn_speed * Game::getIFps());
return 1;
}The following code demonstrates how to receive an event that changed the button state to isKeyDown(), isKeyUp(). Such code can also be used for the mouse and touch buttons.
Source code (C++)
#include "AppWorldLogic.h"
#include <UnigineInput.h>
#include <UnigineConsole.h>
using namespace Unigine;
int AppWorldLogic::update()
{
if (Input::isKeyDown(Input::KEY_T) || Input::isKeyUp(Input::KEY_T))
{
InputEventKeyboardPtr e = Input::getKeyEvent(Input::KEY_T);
Console::messageLine("%s %d time = %lld frame = %lld", Input::getKeyName(e->getKey()), e->getAction(), e->getTimestamp(), e->getFrame());
}
return 1;
}The following code illustrates receiving the immediate input — the user receives the event notification immediately after filtering:
Source code (C++)
#include "AppWorldLogic.h"
#include <UnigineInput.h>
#include <UnigineConsole.h>
using namespace Unigine;
int AppWorldLogic::init()
{
Input::getEventImmediateInput().connect(on_immediate_input);
return 1;
}The following code illustrates how the event filter works. Pressing the "W" button and mouse movements will be declined, i.e. these events won't be taken as input:
Source code (C++)
#include "AppWorldLogic.h"
#include <UnigineInput.h>
using namespace Unigine;
int event_filter(InputEventPtr& e)
{
switch (e->getType())
{
case InputEvent::INPUT_EVENT_KEYBOARD:
{
// skip 'W' key repeat events
InputEventKeyboardPtr k = checked_ptr_cast<InputEventKeyboard>(e);
if (k->getKey() == Input::KEY_W && k->getAction() == InputEventKeyboard::ACTION_REPEAT)
return 1;
break;
}
case InputEvent::INPUT_EVENT_MOUSE_MOTION:
{
// skip all mouse motion events
return 1;
}
default: break;
}
return 0;
}
int AppWorldLogic::init()
{
Input::setEventsFilter(event_filter);
return 1;
}The following code is an example of input events creation. We'll imitate the input of the show_profiler 1 console command as if it were an event from the keyboard.
Source code (C++)
#include "AppWorldLogic.h"
#include <UnigineInput.h>
using namespace Unigine;
enum
{
STATE_OPEN_CONSOLE = 0,
STATE_TYPING_COMMAND,
STATE_APPLY_COMMAND,
STATE_FINISH,
};
int state = STATE_OPEN_CONSOLE;
void emulate_key_input(Input::KEY key)
{
InputEventKeyboardPtr key_down = InputEventKeyboard::create();
key_down->setAction(InputEventKeyboard::ACTION_DOWN);
key_down->setKey(key);
InputEventKeyboardPtr key_repeat = InputEventKeyboard::create();
key_repeat->setAction(InputEventKeyboard::ACTION_REPEAT);
key_repeat->setKey(key);
InputEventKeyboardPtr key_up = InputEventKeyboard::create();
key_up->setAction(InputEventKeyboard::ACTION_UP);
key_up->setKey(key);
Input::sendEvent(key_down);
Input::sendEvent(key_repeat);
Input::sendEvent(key_up);
}
void emulate_text_input(const char *text)
{
int size = strlen(text);
for (int i = 0; i < size; i++)
{
InputEventTextPtr text_input = InputEventText::create();
text_input->setUnicode(text[i]);
Input::sendEvent(text_input);
}
}
int AppWorldLogic::update()
{
switch (state)
{
case STATE_OPEN_CONSOLE:
{
emulate_key_input(Input::KEY_BACK_QUOTE);
state = STATE_TYPING_COMMAND;
break;
}
case STATE_TYPING_COMMAND:
{
emulate_text_input("show_profiler 1");
state = STATE_APPLY_COMMAND;
break;
}
case STATE_APPLY_COMMAND:
{
emulate_key_input(Input::KEY_ENTER);
state = STATE_FINISH;
break;
}
default: break;
}
return 1;
}The following code demonstrates how to obtain various button names using the getKeyName(), keyToUnicode(), and getKeyLocalName() methods:
Source code (C++)
#include "AppWorldLogic.h"
#include <UnigineInput.h>
#include <UnigineConsole.h>
using namespace Unigine;
int AppWorldLogic::init()
{
Console::setOnscreen(true);
return 1;
}
int AppWorldLogic::update()
{
auto print_info = [](const char* state, Input::KEY key)
{
unsigned int unicode = Input::keyToUnicode(key);
Console::message("%s: (key='%s', unicode='%s', local_name='%s') ",
state,
Input::getKeyName(key),
String::unicodeToUtf8(unicode).get(),
Input::getKeyLocalName(key));
};
print_info("Up", Input::KEY_W);
print_info("Jump", Input::KEY_SPACE);
print_info("Run", Input::KEY_RIGHT_SHIFT);
Console::message("\n");
return 1;

Source code (C++)
// implement the MouseDown event handler
void mousedown_event_handler(Input::MOUSE_BUTTON button)
{
Log::message("\Handling MouseDown event\n");
}
//////////////////////////////////////////////////////////////////////////////
// 1. Multiple subscriptions can be linked to an instance of the EventConnections
// class that you can use later to remove all these subscriptions at once
//////////////////////////////////////////////////////////////////////////////
// create an instance of the EventConnections class
EventConnections mousedown_event_connections;
// link to this instance when subscribing to an event (subscription to various events can be linked)
Input::getEventMouseDown().connect(mousedown_event_connections, mousedown_event_handler);
// other subscriptions are also linked to this EventConnections instance
// (e.g. you can subscribe using lambdas)
Input::getEventMouseDown().connect(mousedown_event_connections, [](Input::MOUSE_BUTTON button) {
Log::message("\Handling MouseDown event (lambda).\n");
}
);
// ...
// later all of these linked subscriptions can be removed with a single line
mousedown_event_connections.disconnectAll();
//////////////////////////////////////////////////////////////////////////////
// 2. You can subscribe and unsubscribe via an instance of the EventConnection
// class. And toggle this particular connection off and on, when necessary.
//////////////////////////////////////////////////////////////////////////////
// create an instance of the EventConnection class
EventConnection mousedown_event_connection;
// subscribe to the MouseDown event with a handler function keeping the connection
Input::getEventMouseDown().connect(mousedown_event_connection, mousedown_event_handler);
// ...
// you can temporarily disable a particular event connection to perform certain actions
mousedown_event_connection.setEnabled(false);
// ... actions to be performed
// and enable it back when necessary
mousedown_event_connection.setEnabled(true);
// ...
// remove subscription to the MouseDown event via the connection
mousedown_event_connection.disconnect();
//////////////////////////////////////////////////////////////////////////////
// 3. You can add EventConnection/EventConnections instance as a member of the
// class that handles the event. In this case all linked subscriptions will be
// automatically removed when class destructor is called
//////////////////////////////////////////////////////////////////////////////
// Class handling the event
class SomeClass
{

// ...
// specify a class instance in case a handler method belongs to some class
Input::getEventMouseDown().connect(sc->e_connections, sc, &SomeClass::event_handler);
// ...
// handler class instance is deleted with all its subscriptions removed automatically
delete sc;
//////////////////////////////////////////////////////////////////////////////
// 4. Subscribe to an event saving a particular connection ID
// and unsubscribe later by this ID
//////////////////////////////////////////////////////////////////////////////
// instance of the EventConnections class to manage event connections

);
// remove the subscription later using the ID
Input::getEventMouseDown().disconnect(mousedown_handler_id);

// 5. Ignoring all MouseDown events when necessary
//////////////////////////////////////////////////////////////////////////////
// you can temporarily disable the event to perform certain actions without triggering it
Input::getEventMouseDown().setEnabled(false);
// ... actions to be performed
// and enable it back when necessary
Input::getEventMouseDown().setEnabled(true);Return value
