# 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)
|
|
```
