Popups are collections of elements (positioned assets) that are displayed together. These are different from layouts because they only last for the time that is specified in ticks.
Require Unique
This option is either true or false. If true, the popup will only display is there is not already an element displayed with the same arguments. This is useful for preventing duplicate messages.
Element
An element is a positioned asset on a popup.
Alignment
Whether the layer should align on the right, left, or center. The default alignment is right.
Alignment Types
align:center
Offset
If you would like to move a element around by pixels you would set the offset. Offset works through pixel perfect adjustments.
Position
The position of an element depends on the ScreenSize of the player. It works by percents so 50 = 50%. If you set x = 50 and y = 50 the element would be in the center of the screen. The percentages are precise to a single decimal space.
