I really need help. My enemy can move from left to right, however the animation and the direction of view doesn't work.

private void move()
    {
        if(timer < 75)
        {
            blick=0;
            setLocation(getX() + speed,getY());
        }
        else if(timer > 75)
        {
            blick=1;
            speed = -speed;
            getImage().mirrorHorizontally();
            timer = 0;
        }
        if(blick == 0)
        {
            animateLeft();
        }
        if(blick == 1)
        {
            animateRight();
        }
    }

I also tried this method

if (getObjectsInRange(100,player.class).isEmpty())  
        {
            if (steps == 0)
            {
                blick=0;
                speed = -speed;
            }
            blick=1;
            move(speed);
            if(blick == 0)
            {
                animateLeft();
            }
            if(blick == 1)
            {
                animateRight();
            }
        }

If the animation doesn't work, you should probably show the "animateRight" and "...Left" methods. In the second code, "blick" is set to 1 in line 8, so it will never be 0 in line 10. You also never increase the timer anywhere.

blick isnt supposed to be a timer, but the direction the enemy is looking at. I still changed it so the " blick 1" is called in first. heres the code for the animation

public void animateLeft()
    {
        if(frame == 10)
        {
            setImage(enemy11);
        }
        else if(frame == 20)
        {
            setImage(enemy12);
            frame = 1;
            return;
        }
        frame++;
    }

Yeah, I meant the "timer" in the first code. And you use "steps" in the second one and never change it either.

Show the act method of the class.

private int blick;
public int steps;
private int frame=1;
int timer = 0;
    public enemy1()
    {
        speed1=0;
    }
    public void act() 
    {
        fall();
        counter++;
        timer++;
        steps = (steps + 1) % 75;
        if(Greenfoot.isKeyDown("d"))
        {
            move(-5);
        }
        if(Greenfoot.isKeyDown("a"))
        {
            move(5);
        }
        if(health == 0)
        {
            if (getWorld().getObjects(explosion.class).isEmpty())
            {
                getWorld().addObject(new explosion(),getX(),getY());
            }
            World world = getWorld();
            level1 myWorld = (level1)world;
            counter counter = myWorld.getCounter();
            counter.addScore();
            animateDeath();
            return;
        }
        move();
        shoot();
        hit();
    }

Hm, I am a bit lost I guess. Try moving all the "timer++" and similar code into the method in which they are used. This shouldn't change anything, but it makes it easier to understand what you are doing. It is a bit messy because there are so many variables.

I suggest using just one act counter for the movement/animation. The following is a close example:

public void move()
{
    timer = (timer+1)%160;
    setLocation(getX()+1-2*(timer/80), getY());
    if (timer%10 == 0) setImage(timer/80 == 1 ? (timer%20 == 0 ? enemy11 : enemy12) : (timer%20 == 0 ? enemy01 : enemy02));
}

i probably did something wrong but this isnt really changing much. except that the enemies start gliding away from the player

Wait ... it is quite strange to see key controls in the class of an enemy. Is this really want you are wanting?

mhh... the keys are supposed to be for scrolling world. it does seem to not make sense tho. I'll remove them
