How to detect if a button has been pressed in a simple way

There are two ways to detect if a button has been pressed​

First way​

  • Just add a SUIKeyEventListener to the button in the interface in the properties panel, define its Key and then check it through a script.

In your Java class, do the following:​

package JAVARuntime;

public class YourClass extends Component {
  
  @Override
  public void start() {

  }

  @Override
  public void repeat() {
  
      if(Input.getKey("yourKey").isDown()) {
        
        // your code 
        
      }
      
  }

}

Second way​

  • Just create a public variable of type SUIButton and select your button on the interface in the properties panel.

⚠️ There are many ways to search for a component, to better understand this see the topic Search components, you can search your button in any of these ways. ⚠️

In your Java class, do the following:​

package JAVARuntime;

public class YourClass extends Component {
  
  public SUIButton myButton;
  
  @Override
  public void start() {

  }

  @Override
  public void repeat() {
  
      if(myButton.isDown()) {
        
        // your code 
        
      }
      
  }

}

Understanding the code​

isDown()​

  • Detect touch when the button is touched.

isUp()​

  • Detects touch when the button is released.

isPressed()​

  • Detects touch while the button is being pressed.
