The 广播盒 is a special sign that when powered will announce (in the chat) what was written on the sign.
Certain keywords will change the formatting of the text, for example color.
To change the color of inputted text, type
[c/FFFFFF:] with your text after the colon and any hexadecimal color code in place of "FFFFFF".
[c/66FF66:The blood moon is rising...]will create the output "The blood moon is rising..."
[c/FF66FF:]will create the color shown when an invasion starts or when a boss is summoned.
It is possible to showcase an item in chat, similar to how Alt+Click works in normal chat. To show an item type
[i/zXX:ID ] , where "zXX" is a property of an item, and "ID" is an ID of an item".
[i/s24:2]will show a dirt block with item count 24 in chat
[i/p81:2786]will show the Legendary Solar Flare Pickaxe in chat
Valid item properties are (XX — a number):
The easiest way of getting an Item code is doing the following: first open the chat, Alt+Click needed item, press Ctrl+A to select all text in the chat, and finally press Ctrl+C to copy it. Then you can paste the code into Announcement Box.
You can also write a link to achievement into chat, for this type
[a:NAME] , with "NAME" being an Achievement name
[a:STAR_POWER]will put a message into chat: "Star Power", you can click on it, to open achievement menu at this achievement's position.
Controller buttons can be displayed using the
[g:#] tag, where # corresponds to one of the following functions:
|6||Left shoulder button|
|7||Right shoulder button|
|17||Left stick left|
|18||Left stick right|
|19||Left stick up|
|20||Left stick down|
|21||Right stick left|
|22||Right stick right|
|23||Right stick up|
|24||Right stick down|
|25||Left stick wiggling left and right|
Note that this outputs literal button glyphs, and the output may not match functions assigned in the player's current control scheme. While minor, this could limit the usefulness in custom world designs.
