// Keyboard, mouse, and joystick input polling.
|
|
//
|
|
// Call joeyInputPoll() once per frame (typically right before
|
|
// drawing) to refresh keyboard, mouse, and joystick state. After
|
|
// polling, the joeyKey* predicates return the current state of every
|
|
// key:
|
|
//
|
|
// joeyKeyDown(k) -- is key k held down right now
|
|
// joeyKeyPressed(k) -- rising edge since the previous poll
|
|
// joeyKeyReleased(k) -- falling edge since the previous poll
|
|
//
|
|
// The mouse predicates return the pointer state:
|
|
//
|
|
// joeyMouseX/Y() -- pointer position in surface
|
|
// coords (0..SURFACE_WIDTH-1,
|
|
// 0..SURFACE_HEIGHT-1)
|
|
// joeyMouseDown(b) -- is button b held right now
|
|
// joeyMousePressed(b) -- rising edge since last poll
|
|
// joeyMouseReleased(b) -- falling edge since last poll
|
|
//
|
|
// The joystick predicates return per-stick state:
|
|
//
|
|
// joeyJoystickConnected(js) -- true if the platform reports a
|
|
// stick on this port
|
|
// joeyJoystickX/Y(js) -- axis values, signed -127..+127.
|
|
// Digital sticks snap to the
|
|
// extremes; analog sticks return
|
|
// the raw centered value.
|
|
// joeyJoyDown(js, b) -- is button b held on stick js
|
|
// joeyJoyPressed(js, b) -- rising edge since last poll
|
|
// joeyJoyReleased(js, b) -- falling edge since last poll
|
|
//
|
|
// Edge predicates are one-shot: they return true only in the
|
|
// frame the transition occurred and false thereafter.
