Is there anyway to make it so that if someone starts typing, nothing is displayed until they press enter?

So that this wont happen

Ghaleon says, "hello"
[HP=50/MA=30]: sa
Ghaleon says, "how you doing?"
y hello

Instead it would look like this

Ghaleon says, "hello"
[HP=50/MA=30]: say hello
Ghaleon says, "how you doing?"
You say, "hello"
[HP=50/MA=30]:

Easiest way is to use a real mu* client instead of telnet.

Otherwise, you'd need to use ANSI control sequences to separate the mu*'s text from the user's input. I have no experience doing this, but it's my understanding that it isn't a trivial problem. It will also cause some mu* clients, including mine, to mash everything together and make quite a mess.

You can create a non-scrollable area using ansi(vt) codes and put the prompt in there along with the typing area. It works well if the client is fully compatible with the vt* protocol.

If you're interested in implementing that for real, just post again and I will try to help you.

Forgot to mention, you can also send the turn local echo off ansi code and let the mud handle the echo, it works but it's kinda silly to implement something like that while most clients either support ansi/vt or have their own typing areas.

I've seen the control sequences in action in the early 90s on a mud called silcon realms. It was really slick but occasionally it would mess up and you would have to refresh. It had a static stat display and enemy health bar. You may still have problems after implementing it with fast typers who press a key at the exact moment output is being drawn on thier screen in a place not used for character input.
Here is a list of the ansi controls:

Cursor Controls:
ESC[#;#H or ESC[#;#f Moves cusor to line #, column #
ESC[#A Moves cursor up # lines
ESC[#B Moves cursor down # lines
ESC[#C Moves cursor forward # spaces
ESC[#D Moves cursor back # spaces
ESC[#;#R Reports current cursor line & column
ESC[s Saves cursor position for recall later
ESC[u Return to saved cursor position

Hopefully the forum doesnt mangle it. Enjoy.

Just realized i didnt give you enough codes.

Also i HIGHLY suggest a toggle so players who use a client can recieve the standard prompt and text. Hope it helps.
