<br />
## [Hook Event Types](#Hook-Event-Types)
## [hook_chat_command](#hook_chat_command)
`hook_chat_command()` allows Lua mods to react and respond to chat commands. Chat commands start with the `/` character. The function the mod passes to the hook should return `true` when the command was valid and `false` otherwise.
### Parameters
| Field | Type |
| ----- | ---- |
| command | string |
| description | string |
| func | Lua Function |
### Lua Example
```lua
function on_test_command(msg)
if msg == 'on' then
djui_chat_message_create('Test: enabled')
return true
elseif msg == 'off' then
djui_chat_message_create('Test: disabled')
return true
end
return false
end
hook_chat_command('test', "[on|off] turn test on or off", on_hide_and_seek_command)
```
[:arrow_up_small:](#)
<br />
## [hook_event](#hook_event)
The lua functions sent to `hook_event()` will be automatically called by SM64 when certain events occur.

## [hook_chat_command](#hook_chat_command)
`hook_chat_command()` allows Lua mods to react and respond to chat commands. Chat commands start with the `/` character. The function the mod passes to the hook should return `true` when the command was valid and `false` otherwise.
<br />
## [hook_on_sync_table_change](#hook_on_sync_table_change)
`hook_on_sync_table_change()` allows Lua mods to react to sync table changes.
- `syncTable` parameter must be a sync table, e.g. [gGlobalSyncTable](globals.md#gGlobalSyncTable), [gPlayerSyncTable[]](globals.md#gPlayerSyncTable), or one of their child tables.
- `field` parameter must be one of the fields in the `SyncTable`.
- `tag` parameter can be any type, and is automatically passed to the callback.
- `func` parameter must be a function with three parameters: `tag`, `oldVal`, and `newVal`.
- `tag` will be the same `tag` passed into `hook_on_sync_table_change()`.
- `oldVal` will be the value before it was set.
- `newVal` will be the value that it was set to.
### Parameters
| Field | Type |
| ----- | ---- |
| command | string |
| description | string |
| syncTable | SyncTable |
| field | value |
| tag | value |
| func | Lua Function |
### Lua Example
```lua
function on_test_command(msg)
if msg == 'on' then
djui_chat_message_create('Test: enabled')
return true
elseif msg == 'off' then
djui_chat_message_create('Test: disabled')
return true
end
return false
function on_testing_field_changed(tag, oldVal, newVal)
print('testingField changed:', tag, ',', oldVal, '->', newVal)
end
hook_chat_command('test', "[on|off] turn test on or off", on_hide_and_seek_command)
hook_on_sync_table_change(gGlobalSyncTable, 'testingField', 'tag', on_testing_field_changed)
-- now when testingField is set, either locally or over the network, on_testing_field_changed() will be called
gGlobalSyncTable.testingField = 'hello'
