Longer description

This Minetest mod allows other mods to display a short message at the center of the screen. Each message is displayed for a few seconds, then it is removed. When multiple messages are pushed quickly in succession, the messages will be “stacked” on the screen.

This mod adds the server command “cmsg” as well as an API for mods to display messages. The syntax is “/cmsg <player> <text>”. If <player> is “*”, the message is sent to all players.

This mod can be useful to inform about all sorts of events and is an alternative to use the chat log to display special events.

Some usage examples:

• Messages about game events, like victory, defeat, next round starting, etc.
• Error message directed to a single player
• Informational messages
• Administational messages to warn players about a coming server shutdown
• Show messages by using a command block from Mesecons

Settings

This mod can be configured via minetest.conf.

Currently, these settings are recognized:

• central_message_max: Limit the number of messages displayed at once, by providing a number. Use 0 for no limit. Default: 7
• central_message_time: How long (in seconds) a message is shown. Default: 5
• central_message_color: Set the message color of all messages. Value must be of format (R,G,B). Default: (255,255,255) (white).
