ok, sorry, another topic where i can't find wat im looking for, but i remember someone posting a code that lets the view follow the player but smoother than parenting and another code someone posted that has the background actor follow the view. any codes that work are welcome or at least the link. thx

The trick is to do it from the player's script, not view's. This will keep it instantaneous and smooth.
player>draw actor>
- Code: Select all
view.x=x-320;
view.y=y-240;
background.x=player.x;
background.y=player.y;

the code does great except for one little thing. the background is off. my background is the same size as the view and is aligned perfect in the GE editor, but when i hit game mode, the code makes it move to the bittim right, like this:

This is probably happening due to the discrepancy of xy coordinates of view and other actors. I can't give you direct code, as I don't know your dimensions. If your dimensions are not 640x480, that may be why. If not, can you explain more?

- Code: Select all
view.x=x-view.width/2;
view.y=y-view.height/2;
background.x=player.x;
background.y=player.y;

x=x-(width/2);
This is standard notation for centering objects in a script, used in many languages.
x=x-320;
This is magic number notation for a 640 x480 game.
Why use the magic number? Because width/2 doesn't change. You already know the answer to that equation.
So if your game plays for 10 minutes, at 30 fps, you will compute width/2 no less than 18,000 times. Its not a big deal, but its good to get in the habit of not wasting cpu, even if its only a little bit.

true that, although since this variable changes from game to game, it's good to ask which value their's would be
