Hello. I have a problem with my code.. I want to check if an actor touches another actor and i used if (this.isTouching(brick2.class)) and it works, it returns true but too early.. i remove the object when they are touching each other but it says they touch each other too early, when it s at distance from it.

There is probably excess transparencies around the images of one or both of the interacting actors. Remove all rows and columns along any edge of the images involved that are completely transparent. Use an image editor to do this; or, download my Image Transparency Adder/Trimmer scenario and use it (just run, load and save image to automatically remove excess transparencies; an executable jar file is included in the download to use directly without greenfoot)

In ClassA: 
Actor classB  = null;
for (Object obj : getWorld().getObjects(ClassB.class))
{
    classB = (Actor)obj;
    break;
}
if (classB != null)
{
    // compare here, for example:
    if (classB.getX() > this.getX())
    {
        // do stuff
    }
}
