im pretty new to javascript and im creating a program that allows the user to move images between 6 squares, only 1 image can be in a square at a time, and i need to count how many moves they have made<br> <br> my problem is that i cannot find a way trap the images in a square and center them within this square, i think this will make the number of moves easier to count, any help please!!!! <br>
<br> ps sorry if this posts as a mess but not 100% sure how to format the text with html, not great at that, sorry folks <br> <br> <code> import java.applet.*;<br> import java.awt.*;<br> import java.awt.event.*;<br> import java.awt.image.*;<br> <br>
