[Resolved] Keep screen from going backwards

Getting Started Newbie Questions
#1

How might I go about locking the screen from backwards movement? As everyone probably knows, I have a moveCamera function, but what i’d like to do is like in doodle jump when you go up, the screen doesn’t follow you back down. [import]uid: 147322 topic_id: 27867 reply_id: 327867[/import]

Resolved! Sorry, didn’t think before I posted. For anyone who needs it, here’s an idea:

local limit=256 --set to your character's x (or y), for this example, it is a sideways device  
  
function limitSet() -- function to make a new limit  
 if me.x\>limit then -- 'me' is just your character  
 limit=me.x -- reset limit  
 end  
end  
Runtime:addEventListener("enterFrame", limitSet)  
  
local function moveCamera()  
 if (me.x \> 512 ) and (me.x \>= limit) then -- only if character is not behind limit  
 scrollGroup.x = -me.x + 512  
 end  
end  
Runtime:addEventListener( "enterFrame", moveCamera )
