3 Piece Back Ground scrolling issue

Games
#1

Hi all.

I’ve been trying to create a seamless scrolling background that is 3 screens wide (IT is a seamless BG) and for the life of me a cannot get my ordering worked out… My mind is blank.
Can you help?

this is my code for it

local smoke1 = display.newImage("smoke\_1.png", -960, 265)   
local smoke2 = display.newImage("smoke\_2.png", -480, 265)  
local smoke3 = display.newImage("smoke\_3.png", 0, 265)  
  
-- Animate Smoke Start  
local tPrevious = system.getTimer()  
local function moveSmoke(event)  
  
 local tDelta = event.time - tPrevious  
 tPrevious = event.time  
  
 local xOffset = ( 0.1 \* tDelta )  
  
 smoke1.x = smoke1.x + xOffset  
 smoke1.y = display.contentHeight / 2  
 smoke2.x = smoke2.x + xOffset  
 smoke2.y = display.contentHeight / 2  
 smoke3.x = smoke3.x + xOffset  
 smoke3.y = display.contentHeight / 2  
  
 if smoke1.x \> display.contentWidth + smoke1.width then  
 smoke1:translate( -480 \* 4, 0)  
 end  
 if smoke2.x \> display.contentWidth + smoke2.width then  
 smoke2:translate( -480 \* 4, 0)  
 end  
 if smoke3.x \> display.contentWidth + smoke3.width then  
 smoke3:translate( -480 \* 4, 0)  
 end  
  
end  
Runtime:addEventListener("enterFrame",moveSmoke)

Any help would be appreciated.

Cheers

As you did not say what is not working, I assume that you have huge background images (>1024 pixel). They might have been autosized by Corona. Load them with

display.newImage(“smoke_1.png”, -960, 265, false)

I actually worked out the issue… I had my loop looping in *4 rather than *3 as the rotation criteria… It was l8 and I was tired :slight_smile: [import]uid: 9457 topic_id: 2971 reply_id: 8917[/import]
