How would you go about checking the order in which the character damages or kills something? For instance, say you want to make a keypad with a lock, and there's ten buttons (0 - 9), and you have a five-number activation key which the character types out by shooting the appropriate buttons. How could you check in which order he shoots them?

There are lots of ways to do it. Heres one way:

* Store your key in a table: key[1] = ''o"; key[2]=''p"; key[3]="e"; key[4]=''n";
* Have a variable to keep track of how much of the key has been entered: entered = 1
* When a character/button is destroyed, see if it matches the value in the table: if key[entered] == destoryedChar then...
** If they don't match, then reset the 'entered sequence': entered = 1
** If they do match, then move on to the next key: entered += 1
*** After the +=1, you will need to see if the entire key has been entered: if entered > table.getn(key) then...
**** If so, then the correct key has been entered and you open the door and reset everything
