Let Me Click And Send

A simple Minecraft client-side mod, that reverts the run_command click event restriction introduced in 1.19.1-rc1, so non-command messages can be sent freely as a chat message via run_command click event again

If you want a solution without user awareness, here's a server-side only mod that does the same thing: LetMeClickAndSendForServer

Mod	Side	Advantage	Disadvantage
LetMeClickAndSend	client	Exactly the same behavior as pre mc1.19.1	Needs to be installed on all players' clients
LetMeClickAndSendForServer	server	No need to install on client	Reduces maximum chat message length by 7

Example

Let's run the following command, and then click the shown text

# Minecraft [1.7, 1.21.5)
/tellraw @a {"text":"click me to send \"hi\"","clickEvent":{"action":"run_command","value":"hi"}}

In vanilla 1.19.1 ~ 1.21.4, after clicking, you are not able to say anything since hi is not a valid command (not starts with /)

With this mod, after clicking, you will automatically send a hi chat message to the server, which is the same behavior as the previous Minecraft versions

MC 1.21.5+

Since MC 1.21.5, the run_command behavior has changed a lot

First is the change in command syntax, which has little impact:

# Minecraft [1.21.5, ~)
/tellraw @a {"text":"click me to send \"hi\"","click_event":{"action":"run_command","command":"hi"}}

Next is the change in behavior, which has a greater impact:

• The command value is always valid, regardless of whether it starts with a / or not
• The client will strip the / prefix from the command value and send the remaining string as a command

It's no longer possible to correctly distinguish between "a run_command for sending chat message" and "a run_command for sending command"

As a workaround, LetMeClickAndSendForServer for MC >= 1.21.5 will only replace certain command with the /lmcas command. By default, only command value starting with !!, which is a commonly-used command prefix in MCDReforged plugin ecosystem, will be replaced

A config file located at ./config/letmeclickandsendforserver/config.json is added for customizing the replacing behavior

{
    "sendChatPattern": "!!.*"
}

The sendChatPattern should be a valid regex pattern. All command values that fully match the pattern will be as chat messages

To test with the default configuration, you can use:

/tellraw @a {"text":"click me to send \"!!MCDR\"","click_event":{"action":"run_command","command":"!!MCDR"}}

Requirements

It's a client-side only mod. It requires 0 extra dependency

Requirements:

• Minecraft >= 1.19.1
