A 2d-camera plugin for bevy that works with orthographic cameras.
The motivation is that this could be used for something like a map editor for a 2d game.
Behaves similarly to common online map applications:
Add the plugin to your app
rust ignore
App::new()
.add_plugins(DefaultPlugins)
.add_plugin(PanCamPlugin::default())
.run();
Add the component to an orthographic camera:
rust ignore
commands.spawn(Camera2dBundle::default())
.insert(PanCam::default());
This is enough to get going with sensible defaults.
Alternatively, set the fields of the PanCam component to customize behavior:
rust ignore
commands.spawn(Camera2dBundle::default())
.insert(PanCam {
grab_buttons: vec![MouseButton::Left, MouseButton::Middle], // which buttons should drag the camera
enabled: true, // when false, controls are disabled. See toggle example.
zoom_to_cursor: true, // whether to zoom towards the mouse or the center of the screen
min_scale: 1., // prevent the camera from zooming too far in
max_scale: Some(40.), // prevent the camera from zooming too far out
});
See the simple and toggle examples.
bevy_egui makes pancam cameras not react when the mouse or keyboard focus is on widgets created with bevy_eguiThe main branch targets the latest bevy release.
I intend to support the main branch of Bevy in the bevy-main branch.
