In-Depth Information
You can write these any way you want, but here are some examples to help you get
started:
class IKeyboardHandler
{
virtual bool VOnKeyDown(unsigned int const kcode)=0;
virtual bool VOnKeyUp(unsigned int const kcode)=0;
};
class IPointerHandler
{
public:
virtual bool VOnPointerMove(const CPoint &mousePos)=0;
virtual bool VOnPointerButtonDown(const CPoint &mousePos,
const std::string &buttonName)=0;
virtual bool VOnPointerButtonUp(const CPoint &mousePos,
const std::string &buttonName)=0;
virtual int VGetPointerRadius()=0;
};
class IJoystickHandler
{
virtual bool VOnButtonDown(const std::string &buttonName,
int const pressure)=0;
virtual bool VOnButtonUp(const std::string &buttonName)=0;
virtual bool VOnJoystick(float const x, float const y)=0;
};
class IGamepadHandler
{
virtual bool VOnTrigger(const std::string &triggerName,
float const pressure)=0;
virtual bool VOnButtonDown(const std::string &buttonName,
int const pressure)=0;
virtual bool VOnButtonUp(const std::string &buttonName)=0;
virtual bool VOnDirectionalPad(const std::string &direction)=0;
virtual bool VOnThumbstick(const std::string &stickName,
float const x, float const y)=0;
};
Most functions represent an action taken by a control when something happens to an
input device, such as when a button is pressed or a thumbstick is moved. Here
s how
the return values work: If the message is handled, the functions return
true
; other-
wise, they return
false
.
