Hi everybody,
I'm trying to add Xbox Joystick handle to work with the collision example (which I'm sure would be useful).
So I changed a few settings on some code found on the forum, and you can now move around with the left hat stick.
Here's the code, I think it could be useful to someone (need to be put in the while run loop; and to be combined with the joystick tutorial for initialising the device)
Code: Select all
core::vector3df nodePosition = camera->getPosition();
bool movedWithJoystick = false; //to check if we are using joystick
if(joystickInfo.size() > 0) //if we are using joystick do:
{
f32 moveHorizontal = 0.f;
f32 moveVertical = 0.f;
const SEvent::SJoystickEvent & joystickData = receiver.GetJoystickState();
const f32 DEAD_ZONE = 0.05f; //to prevent
moveHorizontal =
(f32)joystickData.Axis[SEvent::SJoystickEvent::AXIS_X] / 32767.f;
if(fabs(moveHorizontal) < DEAD_ZONE)
moveHorizontal = 0.f;
moveVertical =
(f32)joystickData.Axis[SEvent::SJoystickEvent::AXIS_Y] / 32767.f;
if(fabs(moveVertical) < DEAD_ZONE)
moveVertical = 0.f;
const u16 povDegrees = joystickData.POV / 100;
if(povDegrees < 360)
{
if(povDegrees > 0 && povDegrees < 180)
moveHorizontal = -1.f;
else if(povDegrees > 180)
moveHorizontal = 1.f;
if(povDegrees > 90 && povDegrees < 270)
moveVertical = 1.f;
else if(povDegrees > 270 || povDegrees < 90)
moveVertical = -1.f;
}
if(!core::equals(moveHorizontal, 0.f) || !core::equals(moveVertical, 0.f))
{
nodePosition.Z += MOVEMENT_SPEED * frameDeltaTime * moveHorizontal;
nodePosition.X += MOVEMENT_SPEED * frameDeltaTime * moveVertical;
movedWithJoystick = true;
}
}
camera->setPosition(nodePosition);
My big problem right now is to use the right hat stick to move the camera vision around (like every fps).
And I simply don't know how to check if this stick is used; Can someone tip me ? Thanks.

Alright, it's a bit better, but still not okay.
The displacement do not coincide with the relative angle of the camera, and the angle of the camera does only work for Y axis... Any help?
Code: Select all
core::vector3df nodePosition = camera->getPosition();
core::vector3df nodeRotation = camera->getRotation();
bool movedWithJoystick = false; //to check if we are using joystick
if(joystickInfo.size() > 0) //if we are using joystick do:
{
f32 moveHorizontal = 0.f;
f32 moveVertical = 0.f;
f32 moveHorizontalstick2 = 0.f;
f32 moveVerticalstick2 = 0.f;
const SEvent::SJoystickEvent & joystickData = receiver.GetJoystickState();
const SEvent::SJoystickEvent & joystickData2 = receiver.GetJoystickState();
const f32 DEAD_ZONE = 0.05f; //to prevent
moveHorizontal =
(f32)joystickData.Axis[SEvent::SJoystickEvent::AXIS_X] / 32767.f;
if(fabs(moveHorizontal) < DEAD_ZONE)
moveHorizontal = 0.f;
moveVertical =
(f32)joystickData.Axis[SEvent::SJoystickEvent::AXIS_Y] / 32767.f;
if(fabs(moveVertical) < DEAD_ZONE)
moveVertical = 0.f;
moveHorizontalstick2 =
(f32)joystickData2.Axis[SEvent::SJoystickEvent::AXIS_Z] / 32767.f;
if(fabs(moveHorizontalstick2) < DEAD_ZONE)
moveHorizontalstick2 = 0.f;
moveVerticalstick2 =
(f32)joystickData2.Axis[SEvent::SJoystickEvent::AXIS_R] / 32767.f;
if(fabs(moveVerticalstick2) < DEAD_ZONE)
moveVerticalstick2 = 0.f;
const u16 povDegrees = joystickData.POV / 100;
if(povDegrees < 360)
{
if(povDegrees > 0 && povDegrees < 180)
moveHorizontal = -1.f;
else if(povDegrees > 180)
moveHorizontal = 1.f;
if(povDegrees > 180 && povDegrees < 360)
moveVertical = 1.f;
else if(povDegrees > 360 || povDegrees < 180)
moveVertical = -1.f;
}
const u16 povDegrees2 = joystickData2.POV / 100;
if(povDegrees2 < 360)
{
if(povDegrees2 > 0 && povDegrees2 < 180)
moveHorizontalstick2 = -1.f;
else if(povDegrees2 > 180)
moveHorizontalstick2 = 1.f;
if(povDegrees2 > 180 && povDegrees2 < 360)
moveVerticalstick2 = 1.f;
else if(povDegrees2 > 360 || povDegrees2 < 180)
moveVerticalstick2 = -1.f;
}
if(!core::equals(moveHorizontal, 0.f) || !core::equals(moveVertical, 0.f))
{
nodePosition.Z += MOVEMENT_SPEED * frameDeltaTime * moveHorizontal;
nodePosition.X += MOVEMENT_SPEED * frameDeltaTime * moveVertical;
movedWithJoystick = true;
camera->setPosition(nodePosition);
}
if(!core::equals(moveHorizontalstick2, 0.f) || !core::equals(moveVerticalstick2, 0.f))
{
nodeRotation.Y += MOVEMENT_SPEED2 * frameDeltaTime * moveHorizontalstick2;
nodeRotation.Y += MOVEMENT_SPEED2 * frameDeltaTime * moveVerticalstick2;
movedWithJoystick = true;
camera->setRotation(nodeRotation);
}
}

I'm trying to do something like that for making my camera moving relative to the view orientation and not the scene :
Code: Select all
if(!core::equals(moveHorizontal, 0.f) || !core::equals(moveVertical, 0.f))
{
nodeRotation2 = camera->getRotation();
if((nodeRotation2.Y > 0 && nodeRotation2.Y < 90) || (nodeRotation2.Y > 270 && nodeRotation2.Y < 360)){
nodePosition.Z += MOVEMENT_SPEED * frameDeltaTime * moveHorizontal;}
if(nodeRotation2.Y > 90 && nodeRotation2.Y < 270){
nodePosition.Z += MOVEMENT_SPEED2 * frameDeltaTime * (-moveHorizontal);}
if(nodeRotation2.Y > 180 && nodeRotation2.Y < 360){
nodePosition.X += MOVEMENT_SPEED2 * frameDeltaTime * (-moveVertical);}
if(nodeRotation2.Y > 0 && nodeRotation2.Y < 180){
nodePosition.X += MOVEMENT_SPEED2 * frameDeltaTime * (moveVertical);}
movedWithJoystick = true;
camera->setPosition(nodePosition);
}
With absolutely no success... Any tips guys?

Check the code of CSceneNodeAnimatorCameraFPS::animateNode, I think it does more or less what you want to do. It's in CSceneNodeAnimatorCameraFPS.cpp

Couldn't find what you are talking about !
Anyway, i did it my way :

moveHorizontal =

It all works fine for the movement and the horizontal vision, but not for the vertical vision, I'm trying to figure out why.
But vertical vision works with the two top triggers RT LT... And I just don't know why !
Anyway, I hope someone would find this helpful. And if you don't manage to integrate it, just ask, it would be a pleasure.
