Hello,
I'm working on a scrolling space game and need help with a few mechanics:

1. Finding width:
I have objects in space, like moons and planets, and want them to hide when off-screen. So is there any way to use a script to get the width and height of a clone?

2. Camera Lag Effect:
If the player is always at the center of the screen, it can feel like they're not moving. Instead, I want the camera to slightly lag behind the player.
The camera should have a delayed response when the player starts moving and catch up when they stop, so movement feels smoother and more dynamic.

Any advice on how to implement these? Thanks in advance!

I can help you with hiding objects off-screen, you can basically make a border around the screen that doesn't move and is always on the front layer so that it hides things that are off-screen/stuck to the edge, it's kinda annoying because it makes the screen even smaller
or you can just use a block I use in my scrolling platformers so that I don't have to use a border:

define check
set [ghost] effect to (0)
set [prev pos] to (x position)
change x by (1)
if <(x position) = (prev pos)> then
set [ghost] effect to (100)
end
change x by (-2)
if <(x position) = (prev pos)> then
set [ghost] effect to (100)
end
change x by (1)
set [prev pos] to (y position)
change y by (1)
if <(y position) = (prev pos)> then
set [ghost] effect to (100)
end
change y by (-2)
if <(y position) = (prev pos)> then
set [ghost] effect to (100)
end
change y by (1)
