Detailed Description

Abstract class which allows input to be read from various controllers.

Remarks:: You can access an appropriate concrete subclass of this interface by calling PlatformManager::createInputReader.

Warning:: Temporary implementation only. This class is likely to be refactored into a better design when I get time to look at it properly. For now it's a quick-and-dirty way to get what I need.

Member Function Documentation

void Ogre::InputReader::addCursorMoveListener ( MouseMotionListener * c )

Adds a mouse motion listener to the cursor object.
This keeps the Cursor object hidden.
Definition at line 146 of file OgreInput.cpp.
References Ogre::MouseMotionTarget::addMouseMotionListener(), and mCursor.
Referenced by Ogre::EventProcessor::addCursorMoveListener().

virtual void Ogre::InputReader::capture ( ) [pure virtual]

Captures the state of all the input devices.

Remarks:
This method captures the state of all input devices and stores it internally for use when the enquiry methods are next called. This is done to ensure that all input is captured at once and therefore combinations of input are not subject to time differences when methods are called.

Implemented in Ogre::SDLInput, Ogre::Win32Input, and Ogre::Win32Input8.

void Ogre::InputReader::useBufferedInput ( EventQueue * pEventQueue,

bool keys = true,

bool mouse = true

Tells the reader to use buffered input and update the passed in queue.

Remarks:
The default behaviour of the input reader is simply to capture the current state of the mouse / keyboard on demand. An alternative is to use buffered input where all events are registered on a queue.
