making the sprite move with the background

XxStarCatxX

Okay, so here's what i'm having trouble with… I was thinking how do you make the sprite move with the background? Like, with the arrow keys, the person moves the sprite. When they get to the end of the background, the background moves forward with the sprite. Anyone get it? Sorry, its just its with meh game…

Come see my Animal Jam forum here!
Also, check out my art and projects, you won't regret it!

You need to learn about Scrolling, which you can find here: http://wiki.scratch.mit.edu/wiki/Scrolling_(sprites) .

Scrolling? …Make a sprite which has all of your backdrops, like costume 1 has a village, costume 2 has mountains etc. then do this:

when gf clicked
set [scrollX v] to (-240)
set [scrollY v] to (what Y position the ground is)
show
switch costume to [first costume v]
set [id (only for this sprite) v] to (0)
repeat (number of costumes)
   change [id v] by (1)
   create clone of [myself v]
end
hide
when I start as a clone
forever
  go to x: ((scrollX) + ((id) * (240))) y: (scrollY)
// Meanwhile, in the player sprite...
... :: hat
...
forever
   if <key [key for moving right v] pressed?> then
      if <(x position) < [0]> then
         change x by (how much you want to move)
      else
         change [scrollX v] by (how much you want to move)
      end
   end
   if <key [key for moving left v] pressed?> then
      if <(x position) > [0]> then
         change x by (how much you want to move left)
      else
         change [scrollX v] by (how much you want to move left)

If you want jumping, there's a bit more to it. But this should cover what you're asking for.
EDIT: ninja'd obviously…

See if this helps https://scratch.mit.edu/projects/92682141/

However, like most scrollers it assumes the player stays central and the background moves. You can tweak it so that you only change scrollx when the player is at an edge - eg only scroll if changing x would make it less than -200 or more than 200 and don't change x if that is the case.

(my way so it might not work.)
Make a sprite.
example: this
then use this script: (on the bg sprite)

when green flag clicked
go to x: (0) y: (0)
forever
if <key [left arrow v] pressed?> then
create clone of [myself v]
move (join [-] (speed)) steps
end
if <key [right arrow v] pressed?> then
create clone of [myself v]
move (join [] (speed)) steps
end
end

(the join things are for speed, if you want to do this, type a number.)
if the link doesn't work try this:

when green flag clicked
broadcast [test v]

when I receive [test v]
if <following [RholanT3344]::sensing> then 
say [ok]

else
say [ok, you can do it later]
end
broadcast [test v]

You give no indication of what the clones are doing or why you create them. Better, in my view, to multiply by -1 than join ‘-’ to a variable. What if join is already negative and you've done this multiple times, for example. Move ————————-5 steps??

There's no need to necropost to comment whether or not it worked or to thank anyone. All it does is move someone currently needing help off the top page of the forum.

Will it work for running or racing games?
