Tooltip API

This API explains how to handle the extended item tooltips (description field).

Fields

Add these to the item definition.

• _tt_ignore: If true, the description of this item won't be altered at all
• _tt_help: Custom help text

Once this mod had overwritten the description field of an item was overwritten, it will save the original (unaltered) description in the _tt_original_description field.

tt.register_snippet(func)

Register a custom snippet function. func is a function of the form func(itemstring). It will be called for (nearly) every itemstring.

Returns: Two values, the first one is required. 1st return value: A string you want to append to this item or nil if nothing shall be appended. 2nd return value: If nil, tt will take of the text color. If a ColorString in "#RRGGBB" format, entire text is colorized in this color. Return false to force tt to not apply text any colorization (useful if you want to call minetest.colorize yourself.

Example:

tt.register_snippet(function(itemstring)
	if minetest.get_item_group(itemstring, "magic") == 1 then
		return "This item is magic"
	end
end)
