Is this possible

[Ironside]

Would it be possible to make a trigger, that would do what you type in, for example

If I typed in the game "call BJDebugMsg("Hello")" it would do that? So basicaly it would execute strings writen.

Possible or not?

Possible? Trigger please.

Of course, it depends on the exact effect you want. Example:

• Tr
• Events
  • Map Initialization
• Conditions
• Actions
  • Set Strings[1] = create
  • Set Strings[2] = kill
  • Set Strings[3] = sleep

For each (IntegerA) from 1 to 12, do (Actions)
Loop - Actions
Trigger - Add to Trigger2 <gen> the event (Player - Player(IntegerA) types a message containg <Empty string> as A Substring[/trigger]

• Trigger2
• Events
• Conditions
• Actions
  • If (All conditions are true) then do (Actions) else do (Actions)
    • If - Conditions
      • (Entered chat string) Equal to Strings[1]
    • Then - Actions
      • Set Point1 = (Center of (Playable Map Area))
      • Unit - Create 1 Footman for (Triggering player) at Point1
      • Custom script: call RemoveLocation (udg_Point1)
    • Else - Actions
      • If (All conditions are true) then do (Actions) else do (Actions)
        • If - Conditions
          • (Entered chat string) Equal to Strings[2]
        • Then - Actions
          • Unit - Kill (some unit)

Like this. In case you meant whatever you type to be presented on the screen, here is the trigger:

• Tr
• Events
  • Map Initialization
• Conditions
• Actions
  • For each (IntegerA) from 1 to 12, do (Actions)
    • Loop - Actions
      • Trigger - Add to Trigger2 <gen> the event (Player - Player(IntegerA) types a message containg <Empty string> as A Substring

• Trigger2
• Events
• Conditions
• Actions
  • Set String = (Entered chat string)
  • Custom script: call BJDebugMsg(udg_String)

I've thought of this; sort of writing code from the game instead of the editor. The most embedded ways are:

call ExecuteFunc(GetEventPlayerChatString()) //executes any function by name.  Careful not to type it wrong, as that crashes.
call TriggerExecute(LoadTriggerHandle(udg_Hashtable,0,StringHash(GetEventPlayerChatString())))

 

[Ironside]

Am... So which way works now? Bribe, could you post a whole trigger, including the event, as I'm confused with your function :O

 

[Bribe]

This trigger must be named String if you want to test it out:

function StringFunction takes nothing returns nothing
    call BJDebugMsg("String function executed :)")
endfunction
 
function StringActions takes nothing returns nothing
    //you must type as a chat string "StringFunction" for this to execute properly.
    call ExecuteFunc(GetEventPlayerChatString())
endfunction
 
function InitTrig_String takes nothing returns nothing
    local trigger t=CreateTrigger()
    call TriggerAddAction(t,function StringActions)
    call TriggerRegisterPlayerChatEvent(t,Player(0),"",false)
endfunction

To make it short:
You are only able to run the functions you previously have "enabled".

 

[Ironside]

How do I enable them then?

 

[Anachron]

Basically you have to get the parameters of the entered chat string and convert them to the parameter types of the functions you need.

 

[Ironside]

Example please :O

If you're trying to type code into the game at run-time then you're pretty much going to have to parse it the same way a processor such as JassHelper does it. If the language you want to use to execute code is very simple, then it will be simple to process the information given.

If the user were to type "DoNothing" then you could do:

ExecuteFunc("DoNothing")

Notice "DoNothing" could be referenced as GetEventPlayerChatString().

It would be more complicated for parameters, and you would need to use an assortment of global variables in order to "transfer" the parameter values. Let's say the user typed in: "FogEnable(false)" and you wanted to process that.

globals
    boolean param
endglobals

local string chat = GetEventPlayerChatString()
local string func = null
local string parameter = null
local integer chatlength = StringLength(chat)
local integer i = 0

loop
    exitwhen(i == chatlength)
    if(SubString(chat, i, i+1)=="(") then
        set func = SubString(chat, 0, i)
        set parameter = SubString(chat, 0, i+2, chatlength-1)

        exitwhen(true)
    endif
    set i=i+1
endloop
if(func==null) then
    set func = chat
endif

//assign global parameter value
if(parameter=="true") then
    set param=true
else
    set param=false
endif
call ExecuteFunc(func)

Eh, the parameters are pretty difficult to transfer especially when non-declared functions like natives are used, since ExecuteFunc does not include any parameter values.

Also, there is no function in GUI equivalent to ExecuteFunc, so it would be pretty hard to accomplish.

 

[Ironside]

:S that would take ages for every function to put in :O

EDIT: Is there anyone who uploaded a trigger that has many commands for this string to function thing?

 

[Ironside]

bump

 

[Bribe]

No, this is not recommended protocol. I know it sounds fun and innovative, but in terms of the capability of doing it yourself... that beats the crap out of testing this poor man's script into existence.

 

[Anachron]

Seriously, there is nobody, just try to make it on your own or let it.
Sorry if it sounds harsh, but it's like building a new compiler just for fun.

 

[Ironside]

Ok I'll do my best, and maybe share it if someone else will ever need it. Case Solved.

 

[Teelo]

Jass is not an interpreted language, theres no simple way to be able to write code at run-time and expect it to be executed.

You could, however, design your own interpreter. Expect to spend a lot of time writing things like:
"if (String[1] == "GetPlayerId") then
return GetPlayerId(String[2])
endif"
and a thousand others for every function and parameter in the API. Pretty much would have to duplicate the entire API.
