i added a button to the below codes. and when i click on the button it will only move from tarArray[70,120] to tarArray[80,215]. it will keep repeating that move instead of going to [110,270], 170,…  
can someone take a look at my codes and help me solve this mystery which is wrecking my brain. thankz…
