it only shows the image for a second and turns back to normal to the pirate with full health instead of staying on the second image where he has gotten hurt.
Try commenting out the following 'if' block: 
if (iCounter %10==0){
    iHurt = 1;
    setImage("pirate"+direction+iHurt+".png");
}
That entire block should probably be removed entirely.

I'm not too sure about the oCounter iCounter code, i'll have to ask my teacher as I just used one of the old codes we had. And I commented out the entire block of that if statement. And now once the pirate touches the bomb he's images change, but now he is now not moving left or right when I move him on the arrow keys.

Well, I doubt he was before. Change "Right" to "right" and "Left" to "left" when checking the movement keys in the Pirate class.

Doesn't seem to be working. Oh, and when the pirate gets hit by the bomb and changes image, he also turns right or left and just stays in that direction until he gets hit by another bomb.

Please post your updated Pirate class code. From what I can tell, the pirate should be able to move with the keys after a bomb is contacted. You may have to post the Bomb class code also.

Okay. Let us simplify the code a little bit to make it easier to work with. Instead of having the boolean 'boolExplode' in the Pirate class and the Bomb object removing itself when touching a pirate using the 'boolRemove' variable. We can just have the pirate remove the bomb when touched. In the Pirate class: - remove line 15; - remove line 38; - remove lines 46 through 48; - remove and insert the following at line 37: 
if (isTouching(Bomb.class)){
    removeTouching(Bomb.class);
In the Bomb class: - remove line 11 - replace the entire act method with this: 
public void act()
{
    setLocation(getX(), getY());
    if (getY() > 430) getWorld().removeObject(this);
}
After these changes, test it out and report back what needs to be done next.

Okay so after doing that the character still doesn't change direction, and the bombs are now getting stuck in the Y = 0

I missed adding the '+3' to the 'getY()' in the 'setLocation' line of the Bomb act method. My last line 3 should be: 
setLocation(getX(), getY()+3);
Then, you need a copy of the following line inserted at line 31 of the Pirate class: 
setImage("pirate"+direction+iHurt+".png");

I did not get to the last change that could be done to the Bomb class. You can also remove the 'wasITouched' method from the class.
