Move line 33 to before line 18.
That is not something you want to do every act step. Only when you want to
initiate
adding more asteroids.
Remove line 34 thru 36 and line 41.
Those actions are done in line 37.
Then move lines 30 thru 32 to before line 39.
You only need to do them when you
know
you are going to add an asteroid (after the conditions on line 37 are met).

Is there a method where I can update the string parameter of a GreenfootImage? What I tried was removing the existing tileValue and putting another one in the same place but with the new string.
You want to use the tileValue that is already there and just change the text and image. You need to factor in an
updateImage
method. Move and modify the imaging code in the constructor to the new method. Call the method from the constructor and from the method that has the text change.

My goal (and what I am not sure of) is to add something
using arrays
to regenerate a new color if it is equal to the old color.
It would be quite similar to the expression I used above on line 3. It would, however, then refer to an index pointer to the array. You do not need to pass the length of the array along with the array. You can simply acquire its length by: <Code Omitted>Just add an
int
index pointer field to hold the element number of the current color.

I'm programing abubble shooter game in which i have a cannon at the bottom and two classes for bubbles one class is for bubbles that are already in the world and one class for the bubbles that come out from the cannon.so i want now to compare the bubble image that was fired from the cannon with the bubbles that are already in the world so that after touching if the bubble image from the cannon is the same as the bubble image that is in the world they will be removed. I hope that the problem is clear now.

Cut Block in Stack game

I was wondering how to cut/resize a block in the famous stack game?
At time of cut, you can either create and add 2 new blocks and remove the current or you can add 1 new block (the cut part) and scale the current one. Either way, you will have to calculate the locations at which both final blocks need to be placed as their centers will not match up with the original block.
