Members
void setMouseDY ( ) #
Sets a new screen position change of the mouse pointer along the y axis during the previous frame.
Arguments
- dy - The screen position change of the mouse pointer along the y axis during the previous frame.
getMouseDY() const#
Returns the current screen position change of the mouse pointer along the y axis during the previous frame.
Return value
Current screen position change of the mouse pointer along the y axis during the previous frame.void setMouseDX ( ) #
Sets a new screen position change of the mouse pointer along the x axis during the previous frame.
Arguments
- dx - The screen position change of the mouse pointer along the x axis during the previous frame.
getMouseDX() const#
Returns the current screen position change of the mouse pointer along the x axis during the previous frame.
Return value
Current screen position change of the mouse pointer along the x axis during the previous frame.getTypeName() const#
Returns the current type name of input controls.
Return value
Current type name of input controls.getType() const#
Returns the current type of input controls.
Return value
Current Controls type (one of CONTROLS_* variables):static ControlsPtr create ( int type ) #
Creates a smart pointer to Controls.Arguments
- int type - Type of the controls to be created.
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.
int getState ( int state ) const#
Returns the state of a given control (pressed or unpressed).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
1 if the control is pressed; otherwise, 0.int getStateByName ( const char * name ) const#
Returns the state of a given control (pressed or unpressed) by the control state name.Arguments
- const char * name - Name of the control state. For full list of available controls see Unigine::Controls:: Enumeration at the end of the article.
Return value
1 if the control is pressed; otherwise, 0.const char * getStateName ( int state ) const#
Returns the name of a given control state as a string.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
Name of the control state.int clearState ( int state ) #
Returns a control state and clears it to 0 (not pressed). This function allows to handle control only once even if it is kept pressed over several frames.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.bool saveState ( const Ptr<Stream> & stream ) const#
Saves controls settings into the stream.Example using saveState() and restoreState() methods:
Source code (C++)
// Get the instance of default engine controls and set its state
controls = Engine::getControls();
controls->setMouseDX(5.0f);
// save state
BlobPtr blob_state = Blob::create();
controls->saveState(blob_state);
// change state
controls->setMouseDX(1.0f);
// restore state
blob_state->seekSet(0); // returning the carriage to the start of the blob
controls->restoreState(blob_state);Arguments
Return value
true if the controls settings are saved successfully; otherwise, false.bool restoreState ( const Ptr<Stream> & stream ) #
Restores controls settings from the stream.Example using saveState() and restoreState() methods:
Source code (C++)
// Get the instance of default engine controls and set its state
controls = Engine::getControls();
controls->setMouseDX(5.0f);
// save state
BlobPtr blob_state = Blob::create();
controls->saveState(blob_state);
// change state
controls->setMouseDX(1.0f);
// restore state
blob_state->seekSet(0); // returning the carriage to the start of the blob
controls->restoreState(blob_state);Arguments
Return value
true if the controls settings are restored successfully; otherwise, false.Last update:
