downPtrTrigger->SetData(nullptr, &downBounds,
KeyState::Pressed);
// ...
_actionMoveUp = im->CreateAction();
auto upPadTrigger =
_actionMoveUp->CreateTrigger<GamepadButtonTrigger>();
upPadTrigger->SetData(GamepadButtons::DPad_Up,
KeyState::Pressed);
Once we have created the actions with InputManager , it's just two lines to create a
new trigger based on the type we want and set the desired data. In the first example,
we use AxisBounds created earlier to define a PointerAxisBoundsTrigger , for
which we just define the Y axis, passing nullptr to the X axis.
For the second action we have example code for setting a GamepadButtonTrig-
ger , which is very similar to the KeyTrigger , as you just saw.
We can now fill out the Update method:
void Player::Update(float deltaTime)
{
if (_actionMoveDown->IsTriggered())
{
Move(ShipDirection::Down, deltaTime);
}
else if(_actionMoveUp->IsTriggered())
{
Move(ShipDirection::Up, deltaTime);
}
}
Based on the state of each action we simply call the Move helper command to move
up or down as required. Of course don't forget to hook up the InputManager to
each of the Key and Pointer events in Game.cpp .
