# Advanced Druid Setup
|
|
|
|
## Input Bindings
|
|
|
|
By default, **Druid** uses all key names from Defold's default `/builtins/input/all.input_binding` for input bindings.
|
|
|
|
**Druid** requires the following input bindings:
|
|
|
|
- Mouse trigger: `Button 1` -> `touch` (for basic input components)
|
|
- Mouse trigger: `Wheel up` -> `mouse_wheel_up` (for Scroll component)
|
|
- Mouse trigger: `Wheel down` -> `mouse_wheel_down` (for Scroll component)
|
|
- Key trigger: `Backspace` -> `key_backspace` (for BackHandler component, input component)
|
|
- Key trigger: `Back` -> `key_back` (for BackHandler component, Android back button, input component)
|
|
- Key trigger: `Enter` -> `key_enter` (for Input component, optional)
|
|
- Key trigger: `Esc` -> `key_esc` (for Input component, optional)
|
|
- Key trigger: `Left` -> `key_left` (for Rich Input component, optional)
|
|
- Key trigger: `Right` -> `key_right` (for Rich Input component, optional)
|
|
- Key trigger: `Shift` -> `key_lshift` (for Rich Input component, optional)
|
|
- Key trigger: `Ctrl` -> `key_lctrl` (for Rich Input component, optional)
|
|
- Key trigger: `Super` -> `key_lsuper` (for Rich Input component, optional)
|
|
- Touch triggers: `Touch multi` -> `touch_multi` (for Scroll component)
|
|
|
|
|
|
|
|
|
|
|
|
## Changing Key Bindings
|
|
|
|
If you need to use your own key bindings or key names, you can modify them in your *game.project* file.
|
|
|
|
Here are the default values for key bindings:
|
|
```
|
|
[druid]
|
|
input_text = text
|
|
input_touch = touch
|
|
input_marked_text = marked_text
|
|
input_key_esc = key_esc
|
|
input_key_back = key_back
|
|
input_key_enter = key_enter
|
|
input_key_backspace = key_backspace
|
|
input_multitouch = touch_multi
|
|
input_scroll_up = mouse_wheel_up
|
|
input_scroll_down = mouse_wheel_down
|
|
input_key_left = key_left
|
|
input_key_right = key_right
|
|
input_key_lshift = key_lshift
|
|
input_key_lctrl = key_lctrl
|
|
input_key_lsuper = key_lsuper
|
|
```
|
|
|
|
|
|
## Input Capturing
|
|
|
|
By default, **Druid** automatically captures input focus if any input component is created. Therefore, you do not need to call `msg.post(".", "acquire_input_focus")`.
|
|
|
|
If you do not require this behavior, you can disable it by setting the `druid.no_auto_input` field in the _game.project_ file:
|
|
```
|
|
[druid]
|
|
no_auto_input = 1
|
|
```
|
|
|
|
|
|
## Set Sound Function
|
|
|
|
You can set the sound function to play sounds in the Druid components. Mostly used as a click sound for the buttons.
|
|
|
|
```lua
|
|
local druid = require("druid.druid")
|
|
|
|
-- The callback should play the sound by name: function(sound_id) ... end
|
|
druid.set_sound_function(function(sound_id)
|
|
sound.play("/sounds#" .. sound_id)
|
|
end)
|
|
```
|
|
|
|
|
|
## Set Text Function
|
|
|
|
You can set the text function to get the localized string by locale ID.
|
|
|
|
```lua
|
|
local lang = require("lang.lang")
|
|
local druid = require("druid.druid")
|
|
|
|
-- You can use lang.txp function to get the localized string by locale ID
|
|
druid.set_text_function(lang.txp)
|
|
|
|
-- or custom function with your own logic
|
|
druid.set_text_function(function(locale_id)
|
|
return my_lang_table[locale_id] or locale_id
|
|
end)
|
|
```
|
|
|
|
|
|
## Set Default Style
|
|
|
|
You can set the default style for the Druid components.
|
|
|
|
```lua
|
|
-- Copy the default style from the Druid folder and modify it as needed
|
|
local my_custom_style = require("my.custom.style")
|
|
local druid = require("druid.druid")
|
|
|
|
druid.set_default_style(my_custom_style)
|
|
```
|
|
|
|
|
|
## On Language Change
|
|
|
|
You can set the function to be called when the language changes.
|
|
|
|
```lua
|
|
local lang = require("lang.lang")
|
|
local druid = require("druid.druid")
|
|
|
|
function M.next_language()
|
|
lang.set_next_lang()
|
|
-- When game language changes, call this function to retranslate all Druid components
|
|
druid.on_language_change()
|
|
end
|
|
```
|
|
|
|
|
|
## On Window Callback
|
|
|
|
You can set the function to be called when the window event occurs.
|
|
|
|
```lua
|
|
local druid = require("druid.druid")
|
|
|
|
-- Initialize the window listener, will override the previous window listener
|
|
druid.init_window_listener()
|
|
|
|
-- Or call this function inside window.set_listener
|
|
|
|
-- The callback should be called when the window event occurs: function(event) ... end
|
|
window.set_listener(function(self, event)
|
|
druid.on_window_callback(event)
|
|
end)
|
|
```
|
