Unigine::Controls Class

Header:

#include <UnigineControls.h>

List of functions:

Handles input from the user (keyboard, mouse, joystick or gamepad). It can be used instead of the default engine.controls in one of the two possible ways:

In case you need custom input handling (by AI, for example), you can implement your own controls via ControlsDummy.
You can get the current application controls (i.e. the instance of the default engine controls) via engine.getControls(). After that, you control user input using methods of Controls class exactly the same way as via engine.controls functions.

Such approach, for example, allows to switch between user-controlled input (Controls) and AI-controlled input (ControlsDummy) without having to change the game logic.
Source code (UnigineScript)
```
// Get the instance of default engine controls
Controls controls = engine.getControls();
controls.setMouseDX(5);
```
Here, the function Controls::setMouseDX() does the same as engine.controls.setMouseDX().

The following set of functions is used to register actions (i.e. controls states) that will be executed on the provided input and bind them to specified input events. The actual meaning of all controls registered with CONTROLS_STATE_* variables (for example, CONTROLS_STATE_JUMP or CONTROLS_STATE_FIRE) is defined manually in script by the programmer who uses them. (See how to map controls states and keys).

Controls Class

Members

static ControlsPtr create(int type)

Creates a smart pointer to Controls

Arguments

int type - Type of the controls to be created.

Ptr<Controls> getControls()

Returns current application controls.

Return value

A smart pointer to controls.

void setMouseDX(float mousedx)

Updates a screen position change of the mouse pointer along the X axis.

Arguments

float mousedx - Change of the X coordinate.

float getMouseDX()

Returns a screen position change of the mouse pointer along the X axis during the last frame.

Return value

Change of the X coordinate.

void setMouseDY(float mousedy)

Updates a screen position change of the mouse pointer along the Y axis.

Arguments

float mousedy - Change of the Y coordinate.

float getMouseDY()

Returns a screen position change of the mouse pointer along the Y axis during the last frame.

Return value

Change of the Y coordinate.

int isOwner()

Returns the owner flag. If the pointer is the owner, on its deletion the Controls also will be deleted. Use grab() and release() functions to change ownership.

Return value

1 if the pointer is the owner; otherwise, 0.

void setState(int state, int value)

Updates the state of a given control (i.e. sets the control on or off).

Arguments

int state - Control state number to update. Possible values are in range [STATE_FORWARD;NUM_STATES]. For full list of available controls see Unigine::Controls:: Enumeration at the end of the article.
int value - State value: positive value to "press" the control; 0 to release it.

int getState(int state)

Returns the state of a given control.

Arguments

int state - Control state number. Possible values are in range [STATE_FORWARD;NUM_STATES]. For full list of available controls see Unigine::Controls:: Enumeration at the end of the article.

Return value

Returns the state of the given control.

int getType()

Returns the type of input controls.

Return value

Controls type (one of CONTROLS_* variables):

const char * getTypeName()

Returns a type name of input controls.

Return value

Type name.

int clearState(int state)

Returns a control state and clears it to 0 (control is not pressed).

Arguments

int state - Control state number. Possible values are in range [STATE_FORWARD;NUM_STATES]. For full list of available controls see Unigine::Controls:: Enumeration at the end of the article.

Return value

Returns the state of the given control: 1 if the control is pressed; otherwise,0.

void grab()

Sets the owner flag to 1 for the Controls pointer.

void release()

Sets the owner flag to 0 for the Controls pointer.

int restoreState(const Ptr<Stream> & stream)

Restores controls settings from the stream.

Warning

This function is deprecated and will be removed in the next release.

Arguments

const Ptr<Stream> & stream - Stream smart pointer.

Return value

1 if the controls settings are restored successfully; otherwise, 0.

int saveState(const Ptr<Stream> & stream)

Saves controls settings into the stream.

Warning

This function is deprecated and will be removed in the next release.

Arguments

const Ptr<Stream> & stream - Stream smart pointer.

Return value

1 if the controls settings are saved successfully; otherwise, 0.

int CONTROLS_APP

Description

A ControlsApp instance.

int CONTROLS_DUMMY

Description

ControlsDummy instance.

int CONTROLS_JOYSTICK

Description

Joystick as the input device.

int CONTROLS_SIXAXIS

Description

Sixaxis controller as the input device.

int CONTROLS_XPAD360

Description

XBox 360 game pad as the input device.

int NUM_STATES

Description

The total number of controls states.

int STATE_AUX_0
