Bevy UI Text Input

Text input crate for Bevy UI using cosmic text.

Basic usage

Spawn a TextInputNode component to create a text input:

commands
        .spawn((
            TextInputNode::default(),
            Node {
                width: Val::Px(500.),
                height: Val::Px(250.),
                ..default()
            },
        ))

The size has to be set using Node, there isn't any support for responsive sizing support. The active text input is set using the ActiveTextInput resource. Inputs can also be set to activate when clicked.

There are a couple of examples, text_input is the most complete:

cargo run --example text_input
