Here's a little "function" cfg file I put together to allow the use of alias chaining quite easily. It basically lets you build up a list of commands at your leisure and then run them all at once.

There are lots of uses for this, and I'm going to create a script pack that uses this. Basically, if you ever wanted to build up a list of commands and then execute them all at once later, this script will come in handy.

For example, if you wanted to use this script to charge a fine for players who hurt team members, you could store the ma_takecash commands into an aliaschain and run that chain all at once in round_start.cfg. (So it will hurt their starting cash, not their cash from the previous round.)

Anyway, here's the script:

// CmdChain.cfg by Mattie for EventScripts v0.7.7
// Set chain_name equal to the name of the chain to which you want to append
// Set chain_cmd to the command string you want to append to the alias chain
// Set chain_reset to 1 if you want to reset the chain.
// For example:
//    ...
//    setinfo chain_name rewardchain
//    setinfo chain_cmd 0
//    es_format chain_cmd "es_tell %1 %2;ma_givecash %1 500" event_var(userid) "You deserve a reward!"
//    exec CmdChain.cfg
//    ...
//    rewardchain
//

// initialize variables
es_setinfo chaininit 1
es_setinfo tailname 0
es_setinfo tail 0
es_setinfo aliasname 0
es_format tailname "%1_tail" server_var(chain_name)
es_copy tail server_var(tailname)

// A little trick to try to auto-initialize without a server.cfg
// if-test should work with both v0.7.6.1 and v0.7.7
if (server_var(tail) notequalto 0) then es_setinfo chaininit 0

// if they set "chain_reset" to 1, we need to reset all the chain and
//   null-terminate it.
if (server_var(chain_reset) equalto 1) then es_setinfo chaininit 1
if (server_var(chaininit) equalto 1) then es_setinfo server_var(tailname) 0
if (server_var(chaininit) equalto 1) then es_format aliasname "%1_%2" server_var(chain_name) 0
if (server_var(chaininit) equalto 1) then es alias server_var(chain_name) server_var(aliasname)
if (server_var(chaininit) equalto 1) then es alias server_var(aliasname) ""

// if we aren't resetting, let's add to the existing chain, initialize temp vars
if (server_var(chain_reset) notequalto 1) then es_setinfo aliasname 0
if (server_var(chain_reset) notequalto 1) then es_setinfo aliastailname 0
if (server_var(chain_reset) notequalto 1) then es_setinfo aliasinfo 0

// add something to the alias chain, the tail # will increment by 1
if (server_var(chain_reset) notequalto 1) then es_format aliasname "%1_%2" server_var(chain_name) server_var(tail)
if (server_var(chain_reset) notequalto 1) then es_math tail + 1
if (server_var(chain_reset) notequalto 1) then es es_copy server_var(tailname) tail
if (server_var(chain_reset) notequalto 1) then es_format aliastailname "%1_%2" server_var(chain_name) server_var(tail)

// zero out the last alias in the chain (i.e. null-terminate the chain)
if (server_var(chain_reset) notequalto 1) then es alias server_var(aliastailname) ""
if (server_var(chain_reset) notequalto 1) then es_format aliasinfo "%1;%2" server_var(chain_cmd) server_var(aliastailname)

if (server_var(chain_reset) notequalto 1) then es alias server_var(aliasname) server_var(aliasinfo)

// turn off the reset flag so the caller doesn't make a mistake
if (server_var(chain_reset) equalto 1) then setinfo chain_reset 0

Basically, to use it, just follow the example. Whenever you want to add a new command to the chain you:
1. Set "chain_name" to the name of the alias that will execute the chain
2. Set "chain_cmd" to the string you want to append to the command chain
3. exec CmdChain.cfg

So if I did this:

setinfo chain_name testchain
setinfo chain_cmd "echo Hello"
exec CmdChain.cfg

I would see this when I typed 'alias':

testchain_1 : testchain_0 : echo Hello;testchain_1 testchain : testchain_0

If I then typed:

chain_cmd "echo Hiya!"
exec CmdChain.cfg

then I'd see this when I later typed 'alias':

testchain_2 : testchain_1 : echo Hiya!;testchain_2 testchain_0 : echo Hello;testchain_1 testchain : testchain_0

As you can see, the chain just moves right along appending the commands I want to execute. So if I typed "testchain" it would say:

Hello Hiya!

If I wanted to start the chain over I would just run:

setinfo chain_reset 1
exec CmdChain.cfg

And now alias says:

testchain_2 : testchain_1 : echo Hello;testchain_2 testchain_0 : testchain : testchain_0

Notice that testchain_1 is still there, but isn't in our chain any longer because testchain_0 has been emptied out.

Hope this might come in handy,

P.S. Yes it does say EventScripts v0.7.7 up there because that's all I have at the moment to test with. It may or may not work 100% with v0.7.6.1, but just wait a few days and v0.7.7 will be out. (You'll like it, I bet.)

that's really cool, and i can already think of a couple uses. i do have one request though... in the future, please do not release Advanced ES code this late at night. i hurt my brain figuring it out.

It will be easy to do vector lib with a part of this code :]
