[−][src]Struct ggez::Context
A Context
is an object that holds on to global resources.
It basically tracks hardware state such as the screen, audio
system, timers, and so on. Generally this type is not thread-
safe and only one Context
can exist at a time. Trying to create
another one will fail.
Most functions that interact with the hardware, for instance
drawing things, playing sounds, or loading resources (which then
need to be transformed into a format the hardware likes) will need
to access the Context
.
Fields
filesystem: Filesystem
Filesystem state
timer_context: TimeContext
Timer state
audio_context: Box<dyn AudioContext>
Audio context
keyboard_context: KeyboardContext
Keyboard context
mouse_context: MouseContext
Mouse context
gamepad_context: Box<dyn GamepadContext>
Gamepad context
conf: Conf
The Conf object the Context was created with
continuing: bool
Controls whether or not the event loop should be running.
Methods
impl Context
[src]
pub fn process_event(&mut self, event: &Event) -> Event
[src]
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.
TODO: Resolve hidpi mongling in #391.
This also returns a new version of the Event
that has been modified
for ggez's optional overriding of hidpi. For full discussion see
