So far, I think I’ve made a lot of progress on top of what I did last week. I’m also gradually completing my projects according to the schedule and the list of milestones I set up earlier.

General list of milestones

• At least one external data file
  
• Dictionaries
  
• Custom modules
  
• Definite (for) loops
  
• Custom functions
  
• Have a graphical interface, responding to click events
  
• Consistently available help dialog
  
• Display information about programs state
  
• Have at least 3 levels
  
• Extend a custom turtle class
  
• Have a ‘win’ screen
  
• Have an iterative interface
  
• Use on or more custom images
  

## List of milestones that I have achieved last week

• Improved game interface, added the function of dispalying scores
  
• Added block move, drop function
  
• Added the function of eliminate a row and get the score
  
• Added the function of increasing the score and difficulty when a row is completed
  
• Added the function of changing directions of block, pausing block and changing shapes of block
  

This is my current program

Reflection

• When I first designed the rotate block feature, I didn’t have a clue at first. Because I was able to move the block up, down, left, and right very smoothly by simply increasing or decreasing the coordinates of the block. But when designing the rotation, I couldn’t simply add or subtract coordinates. After reviewing a lot of materials, I found that I could implement the following code, which immediately opened my mind. (active_block_index + 1) % len(active_block.tiles)
• I think my milestones are ambitious enough. Last week I not only completed the original level 1, but also had great success in attempting level 2.
• I am able to keep to my plan. However, I encountered some unforeseen problems in completing my intended plan. I initially thought the function of restarting the game was too simple, thinking that I could just set up a loop, but after I finished the other functions, I found that I couldn’t get the restart to work. This required me to re-examine the entire code. Also my code was redundant in a main file, and I needed to reorganize my code into several modules.

What to do next

• Create one external data file and use dictionaries
  
• Add the function of restart the game
  
• Custom modules and reorganize codes
  
• Add one image
  
• Test whole game
