you need:
-2 counter objects (s x and s y)
-two players (p1 and p2
-an active object for the scrolling

Events:
every 00:00:
-[set counter(s x): x(p1)-x(p2)]
-[set counter (s y): y(p1)-y(p2)]
-[set x position (scroller): x(p1)-vaule (s x)/2]
-[set y position (scroller): y(p1)-vaule (s y)/2]
-Center display: position (scroller)

and volá a two player scrolling engine

Another form of scrolling 2 objects:

If always:
-> center horizontal pos of window in ( X("AO1")+X("AO2") )/2
-> center vertical pos of window in ( Y("AO1")+Y("AO2") )/2

i found a bug, if you keep making the players run away from eachother, they eventually get stuck

It would be helpful if the title said it was 2 player scrolling in the same window not 2 separate. For searching I mean.

Every 00:00 is pointless. It's the same as 'Always'.

I had a similar idea but its object based, i was gonna have an invisible draw line running between the two players and the screen was always centered in the middle of the line... it probably wouldnt have worked

People use every 00:00 in games factory because it seems to be more stable then using 'always', thats what I find, anyway.

This would be good for a 2 player RPG but not for a 2 player platformer.

Simple and easy to though. Good job.

Ah yeah I did this a while ago. Great method. However, the scrolling can tend to shake sometimes, so the best way of doing it is creating another object and getting it to 'follow' the object centred between the players(there are plenty of tutorials on this here if you don't know how), and centring the camera on this object instead, meaning any shaking or sudden movements will be smoothed out.

You might also want to stop the players from going off the screen as if they move too far away they'll go off screen, so you can easily prevent that. For now we'll all have to stick with the 'can't walk any further' method, until a better zoom object is created.

i already knew a similar tecnique, but i'm too lazy to describe it here. btw u can replace that "every 00:00" with "always". Not that it makes any difference, but you save programming time...
