Struct bevy_yoleck::prelude::YoleckEntityUpgradingPlugin
source · pub struct YoleckEntityUpgradingPlugin {
pub app_format_version: usize,
}
Expand description
Support upgrading of entities when the layout of the Yoleck entities and components change.
app.add_plugins(YoleckEntityUpgradingPlugin {
app_format_version: 5,
});
// The newest upgrade, from 4 to 5
app.add_yoleck_entity_upgrade_for(5, "Foo", |data| {
let mut old_data = data.as_object_mut().unwrap().remove("OldFooComponent").unwrap();
data["NewFooComponent"] = old_data;
});
// Some older upgrade, from 2 to 3
app.add_yoleck_entity_upgrade(3, |_type_name, data| {
if let Some(component_data) = data.get_mut("Bar") {
component_data["some_new_field"] = 42.into();
}
});
Fields§
§app_format_version: usize
The current version of the app data.
If YoleckEntityUpgradingPlugin
is not added, the current version is considered 0
(“unversioned”)
Trait Implementations§
source§impl Plugin for YoleckEntityUpgradingPlugin
impl Plugin for YoleckEntityUpgradingPlugin
source§fn ready(&self, _app: &App) -> bool
fn ready(&self, _app: &App) -> bool
Has the plugin finished its setup? This can be useful for plugins that need something
asynchronous to happen before they can finish their setup, like the initialization of a renderer.
Once the plugin is ready,
finish
should be called.source§fn finish(&self, _app: &mut App)
fn finish(&self, _app: &mut App)
Finish adding this plugin to the
App
, once all plugins registered are ready. This can
be useful for plugins that depends on another plugin asynchronous setup, like the renderer.source§fn cleanup(&self, _app: &mut App)
fn cleanup(&self, _app: &mut App)
Runs after all plugins are built and finished, but before the app schedule is executed.
This can be useful if you have some resource that other plugins need during their build step,
but after build you want to remove it and send it to another thread.
