Thank you. I've been looking at this so long I see that my main issue was I never put in import java.text.DecimalFormat;

Maybe you did not understand what I was trying to say above. You need to change the offsets at which you check on the color. If you really want to check that it moves at all, change 'canMove()' to 'true' on line 11.

alright sorry, that I answered it so late but my comment was reported for being potential spam, i figured everything out thanks though

ok thank you very much!

Change line 51 in the Enemy class to 'else if ...'.

Oh wow. I did not know that existed. Thanks!

What text are you trying to remove? are you trying to replace that text? do you not have a Message class? Need more information and code?

Along with your fields declared on lines 12 and 13, add a GifImage reference field and assign a GifImage object given your gif file: <Code Omitted>The gif file should be in the 'images' folder of the project folder. Line 25 should be: <Code Omitted>This line initializes your world background image. The same line of code should also be in the 'act' method of the class to run the animation when the scenario is running.

Move the code in your current constructor into your new constructor and replace your old no-parameter constructor with the following: <Code Omitted>You can then work with the parameter value within the new constructor.

I guess one way is to go through a Menu world to start a new TetrisWorld world by utilizing a second Menu world constructor. Something like this: <Code Omitted>Then, instead of going directly to a new TetrisWorld at restart, go to a Menu world with this: <Code Omitted>

What is line 13 supposed to be doing (what are you intending it to do)? The array is to contain elements of type 'int'. This is a primitive type which cannot be 'null' as all primitive types have default values ('false' for boolean and '0' for all others). So, if line 13 is trying to do what it looks like, then maybe you should check for a meaningless value, like '-1' and set it to that value at lines 18. Lines 18 and 19 seems to deal with a possible different element of the array (using index value from 'x' instead of 'ke'). In fact, it appears that if you use 'x', the index could en

Line 2 should start 'public class'.

In my Pac-Man game, I saved the map as an array in the world, so Pac-Man can check if there is a "wall" on the side. You can download the game and check the code. The alternative is to have walls as actors in the world. Then Pac-Man can move, and if it hits a wall, you place it back to where it came from.
