Info required: the making of the trails along with its codes.

These aren‘t the best solutions, but I can‘t think of any other ideas… 1st You change the Lightcycles into an Object which changes his sizes or 2nd You create lists with the coordinates of the colored places and check if your objects is in range of these objects

public void act() 
    {
        GreenfootImage img = getWorld().getBackground();
        
        if (img.getColorAt(getX(), getY()) == trailColor){
            Greenfoot.stop();
        }
        else{
      
            img.setColor(trailColor);
            img.fillRect(getX(), getY(), trailWidth, trailHeight);
            getWorld().setBackground(img);
            getWorld().repaint();
            move(3);
        }

You may have to use: 
if (trailColor.equals(img.getColorAt(getX(), getY()))){
at line 5.

It worked, but now the problem is that the game stops immediately when i run it. Is there a way to displace the color trail?

What is the trail width and height? I would not make it more than how far the actor moves. Also the trail should be centered at the location. Try subtracting one from both coordinates at which the trail is drawn.

Thank you very much, just one more thing; now my actor dies when he touches his own color but i need the actors to die when they touch the enemies color as well

If you have a flat (single-colored) background, you can just ask if it is not that color. Otherwise, you will need to check both trail colors individually.

How would i do that? do i just write something like: 
if (trailColor.equals(img.getColorAt(getX(), getY()) == color.RED)){
            Greenfoot.stop();
        }

You cannot compare a boolean to a color (see on either side of '==' comparison operator). What are you trying to compare here (you have 3 colors a trail color, a background color and a literal color, in your statement)?

I'm trying to have my actor die, when he touches the other actors trail color. My background is black with some white spots, while the trails of the lightcycles are blue and red respectively

You can use the line I gave above by replacing trailColor with Color.RED or Color.BLUE.
