Layout

Add Layout to an object to line up its children in a row or a column, with even spacing, instead of placing each one by hand. It draws nothing itself. In the Inspector its card is called Layout Group.

Settings

Setting	What it does
direction	Vertical (a column) or Horizontal (a row).
spacing	The gap between children, in px.
PADDING (PX): top, right, bottom, left	Space inside each edge before the first child.
stretch horizontally	In a row, children share the width evenly. In a column, each child fills the full width.
stretch vertically	In a column, children share the height evenly. In a row, each child fills the full height.

Children keep their own size unless a stretch box is checked. Their own positions are ignored: Layout places them, in Hierarchy order.

Put a Layout on an object that also has Scroll and you have a scrolling list.

Fill (optional)

Fill makes the children for you, one copy of a template per entry:

Setting	What it does
fill from	nothing (place children by hand), a list, or a Level Set.
level set	With a Level Set: which Level Set to use. One copy per level; its first Text gets the level's name, and tapping it goes to that level's screen.
list	With a list: which list to show, one copy per entry.
template	A prefab to copy. Leave it empty and the first object you placed inside the layout is the template.
max rows	With a list: show at most this many (a top 10). 0 shows every entry. Rows are added and removed as the list changes.
empty slots	With a list: show empty frames keeps a frame for every slot up to max rows (or the list's Max entries), like an inventory grid with free spaces.
show only	With a list of data objects: show only some entries. Pick by an option field (like type), then tick the options to show, such as only potions. (everything) shows them all.
folder	With a list of data objects: only show things stored in this folder, for example Items/Furniture. Blank shows everything.
placed children	With a list: objects you put inside by hand hide while playing, or keep them (for a header).

What each copy shows comes from List Entry on the template. Tapping a copy sets the list's selected to that entry's position in the full list (even when show only hides some), then runs the template's own tap actions. Showing a List walks through the whole thing.

Good to know

• Grid Layout does the same in a grid, with every cell the same size.
• Fill from a Level Set replaces the old Level Select component.
• Works in games, apps and watch faces. Fill is not offered on watch faces.
• Works in Preview and on both Wear OS and Apple Watch.
