Hello. I am having trouble with coding colours. Here is my code. Does anyone know how to fix this error. The error is "incompatible types: Greenfoot.Color cannot be converted to java.lang.Classes<?>"

public boolean hitWalls()
    {
        if (isTouching(Color.BLACK))
        {
            return true;
        }
        else
        {
            return false;
        }
    }

What objects have the images of the walls?

The method isTouching only works with a second actor. What you could do is this, but it only checks for the exact location the actor is on:

public boolean hitWalls(){
    return getWorld().getColorAt(getX(), getY())==Color.BLACK;
}

Alternatively you could also just make the wall an Actor. Then you could use ifTouching.

By the way you can shorten your code al lot like this:

//instead of this
if(isTouching(Color.BLACK)){
    return true;
}
else{
    return false;
}

//this:
return isTouching(Color.Black);

Hello again, I made a small mistake; take this Code:

return getWorld().getColorAt(getX(), getY()).equals(Color.BLACK);
