try execute shoot method from laucher

        final Button shoot = findViewById(R.id.shoot);
        shoot.setText("Shoot");

        shoot.setOnTouchListener((view, event) -> {
             final boolean[] isShoot = new boolean[] { false };
             if (event.getAction() == MotionEvent.ACTION_DOWN) {
                    isShoot[0] = true;
              } else if (event.getAction() == MotionEvent.ACTION_UP) {
                   isShoot[0] = false;
              }
           /* a callback to the application update */
           game.enqueue(() -> game.shoot());
           return true;
        });

not work

Okay, please test this instead:

final boolean[] isShoot = new boolean[] { false };
isShoot[0] = true;
/* a callback to the application update */
game.enqueue(() -> game.isShoot = isShoot[0]);
return true;

And then test this to see how the MotionEvents get triggered:

    if (event.getAction() == MotionEvent.ACTION_DOWN) {
                    Toast.makeText(getApplicationContext(), "Down", Toast.LENGTH_SHORT).show();
              } else if (event.getAction() == MotionEvent.ACTION_UP) {
                    Toast.makeText(getApplicationContext(), "Up", Toast.LENGTH_SHORT).show();
              }

Also, if you are triggering this from update, you need to reset the isShoot to false, like this:

 if(isShoot){
     shoot();
     isShoot = false;
 }

EDIT:
Also adding a print or a logging statement will help to diagnose the problem:

 if(isShoot){
     shoot();
     Logger.getLogger("DEBUG-SHOOTER").info("Shooting");
     isShoot = false;
 }

ray is not created correctly

How do you know? Did you log it? Or are you guessing because the final thing that should happen isn’t happening?
