attachment.height

Type: number (read/write)
Attachment types: region, mesh

Overview

The base height of the attachment in Spine units.

For region attachments, this is the height of the rectangular image quad before scaling is applied.

For mesh attachments, this is non-essential data from the Spine editor: the mesh is drawn from its vertices, so writing height changes nothing on screen.

For region attachments, setting this property updates the attachment’s geometry at once: the next skeleton:draw() shows the change.

Example

local slot = skeleton:findSlot("gun")
local attachment = slot.attachment

if attachment and attachment.type == "region" then
    -- Make it taller
    attachment.height = attachment.height * 1.2
end
