C++ (Cpp) CursorEventPtr::setSpeed Examples

Example #1

File: Contact.cpp Project: pararthshah/libavg-vaapi

void Contact::calcSpeed(CursorEventPtr pEvent, CursorEventPtr pOldEvent)
{
    if (pEvent->getSpeed() == glm::vec2(0,0)) {
        glm::vec2 posDiff = pEvent->getPos() - pOldEvent->getPos();
        long long timeDiff = pEvent->getWhen() - pOldEvent->getWhen();
        if (timeDiff != 0) {
            pEvent->setSpeed(posDiff/float(timeDiff));
        }
    }
}

Example #2

File: TUIOInputDevice.cpp Project: alimy/libavg

void TUIOInputDevice::setEventSpeed(CursorEventPtr pEvent, glm::vec2 speed)
{
    const glm::vec2 size = getTouchArea();
    glm::vec2 screenSpeed(int(speed.x*size.x+0.5), int(speed.y*size.y+0.5));
    pEvent->setSpeed(screenSpeed/1000.f);
}
