well
goal: goal of this is to have interact with the computers in order to open a door, this is more for the visual.
- 
when player is interacting with one of the computers - if its the right computer order, then it should show green screen
- and if it gets the whole order right, then those who are right computer should light green
 
- 
when player is interacting with one of the computers and it goes wrong - all the computers should show red screens then show black screen
 
- 
if player is half way through the order correct and then interacts with the wrong computer, all computer should show red and then show black screen 
i hope i havent forgot anything
