Scrolling vertical as well as horizontal

I have a frame that is 3840 x 800. It scrolls quite nice across 3x 1280 screen dimensions.
I want to add 3 more screens below so the new dimension would be 3840 x 1600. I can do this but when I move the player it makers the screen wooble when he walks, etc
And when I try to climb down a ladder into the screen below, it just falls andthe camera doesn't follow my player character - any suggestions please

An y suggestions please?

My Project Dimensions are set to: 1280x800
My Frame Dimensions are set to: 3840x1600 (Virtual 3840x1600)
Frame Start has Storyboard/ Centre Display on Player

ok I have tried that but has the same effect.

Here is my Frame Start Code:

To add, I have removed all the code and it still does it!

Should the floor be a backdrop object or an active object - I notice I can set the backdrop to be an obstacle as I found another rule in place that stops the player if collide with ground piece. Although eliminating this part of the code still creates the same results (wobble).
Floor = Active object or Backdrop?

Right I have found the problem but still no solution. The issue is my player character - animated. if I change to a player square block, the screen is fine but the animated pirate is causing the screen to shake. Any settings that could cause this on the animation/player character sprite that I should know about please?

Possibly something to do with the Hot Spot and Acrion Point, although if I set this to the bottom it stops the player being able to move.

The problem appears to be the player sprite. I will try others but if I use a simple square block (un-animated) I don't have this issue. Are there any tips for player sprites to stop this happening.

ok thanks I will try that - obvious when you think of it Is that the method most people use?

On another note, whats the difference if I created as 3840x1600 and 1280x800 frames, thee phone displays this correctly but whats the implications; less mobile compatibility, uses more memory?

Just tried that, created the box image (blue box) and then changed the animated images but still gte the same effect?
How would you create the box frame for the player images just in case I am doing it wrong.

I think I understand now. I created a box that has all the controls, make it invisible and then created the player controller playeranim as well. So in theory I am controlling two sprites around the screen, is that correct? It worked, the wobble stopped.

seems a weird way to create a seperate control for a game creator but oh well... thanks for all your help, much appreciated.

Sop you setall the collision events, etc to the box rather than the player sprite?

i suppose it does, although when i jump it moves the screen up as its following the playerbox. how can i get it so the jump just jumps the player/playerbox without it following them up but also have it so if they move between the lower screens (6 screens in total in one frame) it moves down with them - maybe follow frame rather than player?
