Overrides

Overlay that no other overlay may replace once it is on a cell.

Specification

Applies to: OverlayType
File: rules.ini
Section: [<ObjectType ID>]
Value: boolean
When omitted: no

An overlay with Overrides=yes cannot be replaced by an ordinary overlay placed on its cell during play. The flag is read on the overlay already in the cell, not on the one arriving. When the cell holds an overlay that sets it, the new overlay is refused and the cell keeps what it had.

The test covers ordinary overlays only. Walls, overlays with Land=Railroad, veins and veinholes are placed by their own rules and do not check this flag. Overlays a map places as it loads are not checked either.

Overrides=yes

A refused overlay still plays its CellAnim.
