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
• _tt_food: If true, item is a food item that can be consumed by the player
• _tt_food_hp: Health increase (in HP) for player when consuming food item

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)
