# 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
|
||
|
|
* `_tt_food_satiation`: Satiation increase for player when consuming food item (note: the meaning of satiation is depending on the game being used; some games might not have a satiation mechanic at all, in which case you can skip this field)
|
||
|
|
|
||
|
|
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 and it must return a string you want to append to this item or `nil` if nothing shall be appended.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
```
|
||
|
|
tt.register_snippet(function(itemstring)
|
||
|
|
if minetest.get_item_group(itemstring, "magic") == 1 then
|
||
|
|
return "This item is magic"
|
||
|
|
end
|
||
|
|
end)
|
||
|
|
```
|
