Hi everybody,
I'm pretty sure the solution to my problem is simple, but i'm new to osg and
i'm having a lot of troubles with this...
the problem is that i have to handle multiple key press at once, but for now my
code takes care of just one at a time (the last key you pressed).
here's the code i'm using right now:
Code:
virtual bool handle(const osgGA::GUIEventAdapter& ea, osgGA::GUIActionAdapter&
aa, osg::Object* obj, osg::NodeVisitor* nv)
{
switch (ea.getEventType())
{
// Possible events we can handle
case osgGA::GUIEventAdapter::PUSH: break;
case osgGA::GUIEventAdapter::RELEASE: break;
case osgGA::GUIEventAdapter::MOVE: break;
case osgGA::GUIEventAdapter::DRAG: break;
case osgGA::GUIEventAdapter::SCROLL: break;
case osgGA::GUIEventAdapter::KEYUP: break;
// this one is really handled
case osgGA::GUIEventAdapter::KEYDOWN:
{
switch (ea.getKey())
{
case 'w': { // Rotate upwards
for ROTATION degrees (and keep going forward)
localSpadTransform->preMult(osg::Matrix::rotate(osg::DegreesToRadians(-ROTATION),
osg::X_AXIS));
localSpadTransform->preMult(osg::Matrix::translate(0, SPEED, 0));
return true;
} break; // <--
useless
case 's': { // Rotate downwards
for ROTATION degrees (and keep going forward)
localSpadTransform->preMult(osg::Matrix::rotate(osg::DegreesToRadians(ROTATION),
osg::X_AXIS));
localSpadTransform->preMult(osg::Matrix::translate(0, SPEED, 0));
return true;
} break; //
<-- useless
case 'a': { // Rotate for
ROTATION degrees on the left (and keep going forward)
localSpadTransform->preMult(osg::Matrix::rotate(osg::DegreesToRadians(ROTATION),
osg::Y_AXIS));
localSpadTransform->preMult(osg::Matrix::translate(0, SPEED, 0));
return true;
} break; //
<-- useless
case 'd': { // Rotate for
ROTATION degrees on the right (and keep going forward)
localSpadTransform->preMult(osg::Matrix::rotate(osg::DegreesToRadians(-ROTATION),
osg::Y_AXIS));
localSpadTransform->preMult(osg::Matrix::translate(0, SPEED, 0));
return true;
} break; //
<-- useless
case 'i': { // Rotate upwards
for ROTATION degrees (and keep going forward)
localFokkerTransform->preMult(osg::Matrix::rotate(osg::DegreesToRadians(-ROTATION),
osg::X_AXIS));
localFokkerTransform->preMult(osg::Matrix::translate(0, SPEED, 0));
return true;
} break; // <--
useless
case 'k': { // Rotate downwards
for ROTATION degrees (and keep going forward)
localFokkerTransform->preMult(osg::Matrix::rotate(osg::DegreesToRadians(ROTATION),
osg::X_AXIS));
localFokkerTransform->preMult(osg::Matrix::translate(0, SPEED, 0));
return true;
} break; //
<-- useless
case 'j': { // Rotate for
ROTATION degrees on the left (and keep going forward)
localFokkerTransform->preMult(osg::Matrix::rotate(osg::DegreesToRadians(ROTATION),
osg::Y_AXIS));
localFokkerTransform->preMult(osg::Matrix::translate(0, SPEED, 0));
return true;
} break; //
<-- useless
case 'l': { // Rotate for
ROTATION degrees on the right (and keep going forward)
localFokkerTransform->preMult(osg::Matrix::rotate(osg::DegreesToRadians(-ROTATION),
osg::Y_AXIS));
localFokkerTransform->preMult(osg::Matrix::translate(0, SPEED, 0));
return true;
} break; //
<-- useless
case ' ': { // Reset the
transformation
localSpadTransform->setMatrix(osg::Matrix::identity());
localFokkerTransform->setMatrix(osg::Matrix::identity());
localFokkerTransform->preMult(osg::Matrix::rotate(osg::DegreesToRadians(180.0f),
osg::Z_AXIS));
return true;
} break; //
<-- useless
}
break;
}//switch
//default return
return false;
}
how can i make the program react to multiple key presses?
Thanks in advance
Davide
