Supported types: `box`, `label`, `image`, `button`, `tooltip`, `item_image`, `image_button`, `item_image_button`
Example:
```lua
craftguide.add_formspec_element("export", {
type = "button",
element = function(data)
-- Should return a table of parameters according to the formspec element type.
-- Note: for all buttons, the 'name' parameter *must not* be specified!
if data.recipes then
return {
data.iX - 3.7, -- X
sfinv_only and 7.9 or 8, -- Y
1.6, -- W
1, -- H
ESC(S("Export")) -- label
}
end
end,
-- Optional.
action = function(player, data)
-- When the button is pressed.
print("Exported!")
end
})
```
#### `craftguide.remove_formspec_element(name)`
Removes the formspec element with the given name.
#### `craftguide.get_formspec_elements()`
Returns a map of formspec elements, indexed by name.
