I want to add a booster. For example, when the score is 50, I draw a Texture. When the user clicks on this Texture, I want the enemies on the screen to disappear and return to the original speed. I have completed the drawing process. How can I get this new texture to destroy all enemies on the screen when clicked? Should I do it under public boolean touchDown?
