How to modify SUIButton target by script using Java

In your Java class, do the following:

public class YourClass extends Component {

    // creates a new SpatialObject
    public SpatialObject object; // select from Properties

    // creates a new STargetRect
    public STargetRect type; // select from Properties

    // creates a new SUIButton, @AutoWired selects the component from this object
    @AutoWired
    private SUIButton button;

    @Override
    public void start() {

    }

    @Override
    public void repeat() {

        // changes the type of SUIButton touch area
        button.setTargetRectType(type);

        // defines the object (a SUI component) which will be the touch area of SUIButton
        button.setTargetRectObject(object);
    }
}
