[JASS] ExecuteFunc

[~Void~]

Hm, so just out of pure curiosity, I made this bit of code (with the event of entering a chat string that begins in "Execute ")

call ExecuteFunc(EventPlayerChatString(), 8, StringLength(EventPlayerChatString()))

So basically what this does is when you would type, for example, "Execute CreateUnit(Player(0), 'hfoo', 0.00, 0.00, 270.00)" in game it would do that.

So what I'm wondering is if there is any way to stop it if you make an incorrect argument because right now it just fatal errors.

That's the work of a compiler, isn't it?
You'd have to build a whole compiler, which I think would take some time o.o'

Void, the World Editor JASS Helper is meant to do that work for you, its normally not thought for calling functions out of hea ingame.

You must get EVERY single command and check the values for EVERY command thats alot of work.

Edit: I tried it myself but it seems not to work proberly.

(Wc3 crashes, but when I disable the execution it has the right order)

scope Execute initializer Init

function Actions takes nothing returns nothing
    set udg_Tmp_String = SubString(GetEventPlayerChatString(), 17, ( StringLength(GetEventPlayerChatString()) - 1 ))
    call DisplayTextToForce(GetPlayersAll(),"Your action was: " + udg_Tmp_String)
    call ExecuteFunc(udg_Tmp_String)
endfunction

//===========================================================================
function Init takes nothing returns nothing
    local trigger Trig_Execute= CreateTrigger(  )
    call TriggerRegisterPlayerChatEvent( Trig_Execute, Player(0), "call ExecuteFunc", false )
    call TriggerAddAction( Trig_Execute, function Actions )
    set Trig_Execute = null
endfunction

endscope

ExecuteFunc can't take parameters... It can only be used on functions taking nothing returning nothing

IDEA!!!!

So you can have globals inside that function, which are setted after typing the command, eh?

 

[Eleandor]

Still means you have to have a huge conditional statement that executes a different function based on what you typed... i.e.

if (command == "CreateUnit") then
elseif (command == "KillUnit") then
etc
endif

Then you also have the problem that the parameters have virtually infinite possibilities... For example: KillUnit takes a unit parameter... Which unit will that be?

 

[Anachron]

Well, but most of the blizzards functions (natives) have the same syntax.
For example UnitAddAbility is the same as UnitRemoveAbility.

So you can make it shorter with that.

At another point of view, you are totally right.

It would be even faster to create own functions as running one from
chat messages.

And why would you want to have this kind of interface anyway? I mean, if you want to give e.g. a game master godly powers over the course of the map (i.e. killing units, etc.) then a text-based interface is probably not what you want. It'd be better to at least use a "god powers building" with abilities such as "Kill Unit" that simply kills the unit that's targeted.
Or "Create Unit" that has to target a unit (from a small spot on the map containing all possible units) and then automatically has to target a point which creates a duplicate of the targeted unit at the point...

 

[Anachron]

I see, but wouldn't it be awesome to be able to change the whole map, just temporary, for testing and error seeking? It would help so much.

It can be cool to make new functions in-game, which will turn out as "in-game world editing", but it would just be too hard to do it in real time, say on b.net.
