  • Input Event Classes

This module provides input event classes. Input event objects are used to consolidate all necessary information about input events in a clean way.

You normally don’t need to use input event objects directly. Input events are handled automatically in each frame of the SGE’s main loop. You only need to use input event objects directly if you take control away from the SGE’s main loop, e.g. to create your own loop.

This input event represents a key on the keyboard being pressed.

key

The identifier string of the key that was pressed. See the table in the documentation for sge.keyboard.

x

The horizontal position of the hat, where 0 is centered, -1 is left, and 1 is right.

y

The vertical position of the hat, where 0 is centered, -1 is up, and 1 is down.

class sge.input.JoystickTrackballMove(js_name, js_id, ball, x, y)

This input event represents a joystick trackball moving.

The name of the joystick.

js_id

The number of the joystick, where 0 is the first joystick.

button

The number of the button that was pressed, where 0 is the first button on the joystick.

class sge.input.JoystickButtonRelease(js_name, js_id, button)

This input event represents a joystick button being released.

js_name

The name of the joystick.

js_id

The number of the joystick, where 0 is the first joystick.

button

The number of the button that was released, where 0 is the first button on the joystick.

class sge.input.KeyboardFocusGain

This input event represents the game window gaining keyboard focus. Keyboard focus is normally needed for keyboard input to be received.

Note

On some window systems, such as the one used by Windows, no distinction is made between keyboard and mouse focus, but on some other window systems, such as the X Window System, a distinction is made: one window can have keyboard focus while another has mouse focus. Be careful to observe the difference; failing to do so may result in annoying bugs, and you won’t notice these bugs if you are testing on a window manager that doesn’t recognize the difference.

class sge.input.KeyboardFocusLose

This input event represents the game window losing keyboard focus. Keyboard focus is normally needed for keyboard input to be received.

Note

See the note in the documentation for sge.input.KeyboardFocusGain.

class sge.input.MouseFocusGain

This input event represents the game window gaining mouse focus. Mouse focus is normally needed for mouse input to be received.

Note

See the note in the documentation for sge.input.KeyboardFocusGain.

class sge.input.MouseFocusLose

This input event represents the game window losing mouse focus. Mouse focus is normally needed for mouse input to be received.

Note

See the note in the documentation for sge.input.KeyboardFocusGain.

class sge.input.QuitRequest

This input event represents the OS requesting for the program to close (e.g. when the user presses a “close” button on the window border).
