You can use Greenfoot.mousePressed. And then an additional condition (Greenfoot.mouseClicked) to change back. It's only true after the mouse has been released. I'm not clear in what you mean by "appear text".

import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)

/**
 * Write a description of class Button here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
public class Button extends Actor
{
    public Button()
    {
        setImage("button.png");
    }
    
    /**
     * Act - do whatever the Button wants to do. This method is called whenever
     * the 'Act' or 'Run' button gets pressed in the environment.
     */
    public void act() 
    {
        // Add your action code here.
        clickButton();
         
    }
    
    public void clickButton()
    {
        GreenfootImage gfim = new GreenfootImage(900,600);
        if(Greenfoot.mouseClicked("button.png")==true)
        {
            
            gfim.drawString("fi", 200, 200);
            
        }      
    }
}

when I click on the image of the button, the drawing of the text appears next to it, not that it works or otherwise create the button in the shape of a drawing

Are you trying to replace the button image with the image of the text "fi"? If not, you need to set this new image to another actor or draw the image onto the background image.

Another option is to use the World instance method showText.
