Unigine::Controls Class

Header:

#include <UnigineControls.h>

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).

Members

static ControlsPtr create ( int type ) #

Creates a smart pointer to Controls.

Arguments

int type - Type of the controls to be created.

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 previous 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 previous frame.

Return value

Change of the Y coordinate.

void setState ( int state, int value ) #

Toggles the state of the given 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.
