Expand description
The event
module contains traits and structs to actually run your game mainloop
and handle top-level state, as well as handle input events such as keyboard
and mouse.
If you don’t want to use ggez
’s built in event loop, you can
write your own mainloop and check for events on your own. This is
not particularly hard, there’s nothing special about the
EventHandler
trait. It just tries to simplify the process a
little. For examples of how to write your own main loop, see the
source code for this module, or the eventloop
example.
Re-exports
pub use crate::input::gamepad::GamepadId;
Modules
winit
events; nested in a module for re-export neatness.
Structs
winit
event loop.
Provides a way to retrieve events from the system and from the windows that were registered to
the events loop.
Enums
An analog axis of some device (gamepad thumbstick, joystick…). Gamepad’s elements which state can be represented by value from -1.0 to 1.0.
A button of some device (gamepad, joystick…). Gamepad’s elements which state can be represented by value from 0.0 to 1.0.
winit
event loop.
Set by the user callback given to the EventLoop::run
method.
Used in EventHandler::on_error()
to specify where an error originated
A mouse button. Describes a button of a mouse controller.
Traits
A trait defining event callbacks. This is your primary interface with
ggez
’s event loop. Implement this trait for a type and
override at least the update()
and
draw()
methods, then pass it to
event::run()
to run the game’s mainloop.
Functions
Feeds an Event
into the Context
so it can update any internal
state it needs to, such as detecting window resizes. If you are
rolling your own event loop, you should call this on the events
you receive before processing them yourself.
Attempts to terminate the ggez::event::run()
loop by requesting a
quit_event
at the very start of the next frame. If this event
returns Ok(false)
, then Context.continuing
is set to false
and the loop breaks.
Runs the game’s main loop, calling event callbacks on the given state object as events occur.
Type Definitions
A mouse button. Hardware-dependent keyboard scan code.
