Chat color

In the following example, once present in your world, every visitor who enters !chatbleuciel in the chat window will receive the message Vous écrivez en Bleu ciel in whisper and will from then on write in chat with the color skyblue.
To access these parameters, click on Add in the Dictionary. tab.
To store a visitor's choice, so they won't have to repeat the same command every time when visiting your world, specify a character other than 0 (zero) or No in the field Permanent.
Repeat this step for each desired color.


  • If your bot is offline, nobody will be able to speak in chat in your world and only whispers can be used with others in the same area.

  • Our tests provided that it should be recommended to dedicated a bot to this color function and this function only. Indeed, its speed seems lagging behind in the chat when the bot has to perform other simultaneous actions.

  • The server choice is also of importance because even a slow or instable connection could cause delays in the display of the chat.

  • All messages send to the chat window will be visible throughout your world, even for those not in your direct area, tourists and citizens alike, eventhough you will only see the alias names of other visitors in your direct area when pulling down the whisper list.

  • The possibility to write in bold will be deactivated. If you wish to conserve this option, reserve an additional command in your bot.
