Bevy Transform Gizmo

This Bevy plugin adds a transform gizmo to entities in the scene, allowing you to drag and rotate meshes with your mouse.

Demo

Run a minimal implementation of the gizmo by cloning this repository and running:

cargo run --example minimal

Features

• Prebuilt transform gizmo appears when you select a designated mesh
• Translation handles
• Rotation handles
• Gizmo always renders on top of the main render pass
• Gizmo scales at it moves closer/further from the camera

Usage

This plugin is built on and relies on bevy_mod_picking for 3d mouse interaction with the scene.

Add the plugin to the [dependencies] in Cargo.toml

bevy_transform_gizmo = { git = "https://github.com/ForesightMiningSoftwareCorporation/bevy_transform_gizmo", branch = "main" }

You will need to add the transform gizmo plugin, as well as make sure you have also brought in the picking plugin.

.add_plugin(bevy_mod_picking::DefaultPickingPlugins)
.add_plugin(bevy_transform_gizmo::TransformGizmoPlugin)

Next, you will need to mark your picking camera as your gizmo camera:

.insert_bundle(bevy_mod_picking::PickingCameraBundle::default())
.insert(bevy_transform_gizmo::GizmoPickSource::default());

Finally, mark any meshes you want to be transformed with the gizmo; note they must also be selectable in the picking plugin:

.insert_bundle(bevy_mod_picking::PickableBundle::default())
.insert(bevy_transform_gizmo::GizmoTransformable);

See the minimal demo for an example of a minimal implementation.
