From 9e3b65368873fd26f21e2568b2c67d00ec96d6a5 Mon Sep 17 00:00:00 2001 From: Jordan Woyak Date: Mon, 21 Jun 2010 03:12:16 +0000 Subject: GCPad/New Wiimote Plugin: Individual keyboard and mouse devices are now listed on Windows(2 player with 2 keyboards possible). Improved the ability to map multiple inputs to the same control. Inputs from different devices can be mapped to the same button (example: Mouse Left and XInput A). More advanced mappings such as "Button 1 or 2 and NOT button 3" are possible. I hope the GUI after right clicking a button isn't too confusing(may change it to be a bit more user friendly). Hopefully, I didn't break OSX stuff by 'const'ing a few functions. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5757 8ced0084-cf51-0410-be5f-012b33b47a6e --- .../DirectInput/DirectInputMouse.cpp | 175 +++++++++++++++++++++ 1 file changed, 175 insertions(+) create mode 100644 Source/Core/InputCommon/Src/ControllerInterface/DirectInput/DirectInputMouse.cpp (limited to 'Source/Core/InputCommon/Src/ControllerInterface/DirectInput/DirectInputMouse.cpp') diff --git a/Source/Core/InputCommon/Src/ControllerInterface/DirectInput/DirectInputMouse.cpp b/Source/Core/InputCommon/Src/ControllerInterface/DirectInput/DirectInputMouse.cpp new file mode 100644 index 0000000000..122582bf4f --- /dev/null +++ b/Source/Core/InputCommon/Src/ControllerInterface/DirectInput/DirectInputMouse.cpp @@ -0,0 +1,175 @@ +#include "../ControllerInterface.h" + +#ifdef CIFACE_USE_DIRECTINPUT_MOUSE + +#include "DirectInputMouse.h" +#include "DirectInput.h" + +// TODO: maybe add a ClearInputState function to this device + + // (lower would be more sensitive) user can lower sensitivity by setting range + // seems decent here ( at 8 ), I dont think anyone would need more sensitive than this + // and user can lower it much farther than they would want to with the range +#define MOUSE_AXIS_SENSITIVITY 8 + + // if input hasn't been received for this many ms, mouse input will be skipped + // otherwise it is just some crazy value +#define DROP_INPUT_TIME 250 + +namespace ciface +{ +namespace DirectInput +{ + +void InitMouse( IDirectInput8* const idi8, std::vector& devices ) +{ + LPDIRECTINPUTDEVICE8 mo_device; + + unsigned int mo_count = 0; + + std::list mice; + idi8->EnumDevices(DI8DEVCLASS_POINTER, DIEnumDevicesCallback, (LPVOID)&mice, DIEDFL_ATTACHEDONLY); + + // add other keyboard devices + std::list::iterator + i = mice.begin(), + e = mice.end(); + for (; i!=e; ++i) + { + if (SUCCEEDED(idi8->CreateDevice(i->guidInstance, &mo_device, NULL))) + { + if (SUCCEEDED(mo_device->SetDataFormat(&c_dfDIMouse2))) + if (SUCCEEDED(mo_device->SetCooperativeLevel(NULL, DISCL_BACKGROUND | DISCL_NONEXCLUSIVE))) + { + devices.push_back(new Mouse(mo_device, mo_count++)); + return; + } + } + mo_device->Release(); + } +} + +Mouse::~Mouse() +{ + // mouse + m_mo_device->Unacquire(); + m_mo_device->Release(); +} + +Mouse::Mouse(const LPDIRECTINPUTDEVICE8 mo_device, const int index) + : m_mo_device(mo_device) + , m_index(index) +{ + m_mo_device->Acquire(); + + m_last_update = GetTickCount(); + ZeroMemory(&m_state_in, sizeof(m_state_in)); + + // MOUSE + // get caps + DIDEVCAPS mouse_caps; + ZeroMemory( &mouse_caps, sizeof(mouse_caps) ); + mouse_caps.dwSize = sizeof(mouse_caps); + m_mo_device->GetCapabilities(&mouse_caps); + // mouse buttons + for (unsigned int i = 0; i < mouse_caps.dwButtons; ++i) + AddInput(new Button(i)); + // mouse axes + for (unsigned int i = 0; i < mouse_caps.dwAxes; ++i) + { + // each axis gets a negative and a positive input instance associated with it + AddInput(new Axis(i, (2==i) ? -1 : -MOUSE_AXIS_SENSITIVITY)); + AddInput(new Axis(i, -(2==i) ? 1 : MOUSE_AXIS_SENSITIVITY)); + } + +} + +bool Mouse::UpdateInput() +{ + DIMOUSESTATE2 tmp_mouse; + HRESULT hr = m_mo_device->GetDeviceState(sizeof(tmp_mouse), &tmp_mouse); + + // if mouse position hasn't been updated in a short while, skip a dev state + const DWORD cur_time = GetTickCount(); + if (cur_time - m_last_update > DROP_INPUT_TIME) + { + // set buttons/axes to zero + // skip this input state + ZeroMemory(&m_state_in, sizeof(m_state_in)); + } + else if (SUCCEEDED(hr)) + { + // need to smooth out the axes, otherwise it doesnt work for shit + for (unsigned int i = 0; i < 3; ++i) + ((&m_state_in.lX)[i] += (&tmp_mouse.lX)[i]) /= 2; + + // copy over the buttons + memcpy(m_state_in.rgbButtons, tmp_mouse.rgbButtons, sizeof(m_state_in.rgbButtons)); + } + + m_last_update = cur_time; + + if (DIERR_INPUTLOST == hr || DIERR_NOTACQUIRED == hr) + m_mo_device->Acquire(); + + return SUCCEEDED(hr); +} + +bool Mouse::UpdateOutput() +{ + return true; +} + +std::string Mouse::GetName() const +{ + return "Mouse"; +} + +int Mouse::GetId() const +{ + return m_index; +} + +std::string Mouse::GetSource() const +{ + return DINPUT_SOURCE_NAME; +} + +ControlState Mouse::GetInputState( const ControllerInterface::Device::Input* const input ) const +{ + return (((Input*)input)->GetState(&m_state_in)); +} + +void Mouse::SetOutputState(const ControllerInterface::Device::Output* const output, const ControlState state) +{ + return; +} + +// names +std::string Mouse::Button::GetName() const +{ + return std::string("Button ") + char('0'+m_index); +} + +std::string Mouse::Axis::GetName() const +{ + std::string tmpstr("Mouse "); + tmpstr += "XYZ"[m_index]; tmpstr += ( m_range>0 ?
