Summary

Bevy RTS Camera provides an RTS-style camera for Bevy Engine, to get your game up and running quickly. Designed for simple use cases, and does not try to cover advanced requirements.

Features:

• Pan, zoom, and rotation
• Automatically follows whatever you mark as 'ground'
• Smoothed movement
• Customisable controls and other settings
• Comes with optional controller, or you can control it yourself

Default Controller

A default controller is included with these default controls:

• Arrow Keys: pan
• Mouse Wheel: zoom
• Middle Mouse: rotate

You can also 'edge pan' by moving the mouse to the edge of the screen.

Quick Start

Add the plugin:

.add_plugins(RtsCameraPlugin)

Add RtsCamera (this will automatically add a Camera3d but you can add it manually if necessary):

commands.spawn((
    RtsCamera::default(),
    RtsCameraControls::default(),  // Optional
));

Add Ground to your ground/terrain entities:

commands.spawn((
    PbrBundle {
        mesh: meshes.add(Plane3d::default().mesh().size(80.0, 80.0)),
        ..default()
    },
    Ground,
));

This will set up a camera at world origin with good defaults based on a roughly realistic scale (where an average human is 1.75 units tall).
