Have simple probleam

[zwzsg]

No.

Echo can used be both in synced and unsynced.


However,

When you press a key, you are alone to press the key. You're not pressing the key of other players along as yours.

Keypresses are by definition unsynced!


Working exemple:

Code: Select all

function gadget:GetInfo()
	return {
		name = "KeyCatchEx",
		desc = "Show how to catch keypresses in gadgets",
		author = "zwzsg",
		date = "21st of January 2010",
		version = "1.0",
		license = "Public Domain",
		layer = 0,
		enabled = true
	}
end

local up_arrow,down_arrow,right_arrow,left_arrow,enter,space,dee = 273,274,275,276,13,32,100

local message_identifier = gadget:GetInfo().name..": "

if (gadgetHandler:IsSyncedCode()) then--SYNCED

	function gadget:RecvLuaMsg(msg,player)
		local MsgForMe=string.match(msg,message_identifier.."(.*)")
		if MsgForMe then
			Spring.Echo("Synced recieved a message from unsynced:")
			Spring.Echo(MsgForMe)
		end
	end

else--UNSYNCED

	function gadget:KeyPress(key)
		Spring.Echo("Key "..key.." pressed in unsynced")
		Spring.SendLuaRulesMsg(message_identifier..key.." was pressed")
	end

end

Keypresses are by definition unsynced!

This. Same with mouse.

Thanks all for all the info and help :)

I am still a little puzzled by this though

I tried out zwzsg sript wich he provided (thank you for takeing the time and energy zwzsg) and it did not work (wich means I managed to somehow screw it up) the expected text did not show up in the console or infolog

the fact it did not work segjests I am making some SUPER stupid error by assuming something I should not be

so let me put down a few simple things I have been doing and assumeing are right

1) gadgets go in the LuaRules/Gadets folder

2) gadgets must have same save name as the name depicted in function gadget:GetInfo()

3) its ok to keep spring lobby open when adding/changing gadgets

4) you need to start your spring game after all gadgets are ready to be tested

5) widgets with the function gadget:KeyPress(key) cant interfear with gadgets that have the function gadget:KeyPress(key) even if they are in the game mod at the same time

6) haveing the text file of a gadget open wile game is running is ok

...

I cant think of much more right now

...

the fact that something this simple is giving me this much trouble makes me wonder if I put something in my mod that is interfearing with gadgets Spring.Echo command (I dont know if that is even possible) but it is worth mentioning that I made a widget with the echo that works fine everytime...

at this point I am pretty lost and puzzled at what my next simple step should be

I guess I will take out all other gadgets and see if it works with just that one in there

thanks for helping me through this guys :) hope I can repay one day

[zwzsg]

and it did not work

That's odd. I did test right before posting.

gadgets go in the LuaRules/Gadets folder

I hope you spelt the folder name correctly...

gadgets must have same save name as the name depicted in function gadget:GetInfo()

Not necessarly.

3) its ok to keep spring lobby open when adding/changing gadgets

Yeah.

4) you need to start your spring game after all gadgets are ready to be tested

Yeah.

Or you could use the command /luarules reload

5) widgets with the function gadget:KeyPress(key) cannot interfear with gadgets that have the function gadget:KeyPress(key) even if they are in the game mod at the same time

Hmm, not sure!

If I recall well, when a KeyPress returns false, it means the gadget didn't take it, and is letting the KeyPress free to be grabbed by another gadget. But when KeyPress returns true, it means the gadget took the keypress, and the keypress is not anymore available to other gadget, other widgets, or the engine.

6) haveing the text file of a gadget open wile game is running is ok

Yes.

[Voidranaut]

ok so I played with removeing gadgets and found out what I did that was stopping the gadget from working

oddly enough it had everything to do with a probleam I was gettting help on with another thread in this forum

I took the unit_morph gadget and made a copy of it then modded the copy (I was trying to gain the ability to give units multiple morphing buttons but managed to create this error)

error = 2, LuaRules/draw.lua, error = 2, LuaGadgets/gadgets.lua, [string "LuaGadgets/actions.lua"]:54: attempt to index local 'g' (a function value)

now from what I heard the error could mean a few things but with the fact that it stoped zwzsg script I was wondering if that helps narrow down what I could have done wrong with my original script

if not oh well

but the big point is that zwzsg's script works great and I have deffently learned alot from you guys thanks :)

hay one last question

local MsgForMe=string.match(msg,message_identifier.."(.*)")

what significance is the red syntax?

[smoth]

Good luck with whatever endeavor you pursue. Sorry for my shitty advice early on.

[Argh]

error = 2, LuaRules/draw.lua, error = 2, LuaGadgets/gadgets.lua, [string "LuaGadgets/actions.lua"]:54: attempt to index local 'g' (a function value)

That kind of error halts gadgetHandler, IIRC, and can basically crash the whole Lua state for Gadgets.

IOW, if you have an error that bad (usually comes up with people attempting to port CA Gadgets, hmm) then you probably needed something from CA's Gadget files in the LuaRules directory (action.lua, system.lua, etc.) before it will operate.

So, removing that thing basically removed the conflict and allowed zwswg's code to operate.

[Forboding Angel]

Yeah, morph has bricked evo gadgets before. Once you actually know what's going on the fix is fairly simple, but when you're staring at infolog going "OMGWTF?!?!?! GHEY!"... yeah.

[zwzsg]

hay one last question

local MsgForMe=string.match(msg,message_identifier.."(.*)")

what significance is the red syntax?

It's a RegExp. Don't even try to understand that now.

Regular Expresions are very powerful, but very hard to come up with or even decode. Leave them to the Wizards.

The whole line though put into "MsgForMe" the part of the string "msg" that follows the identifier (or nil if there is no identifier).

[lurker]

Specifically, () means "output the part inside the ()" and .* means "everything from here to the end".
But if you want a simpler method (which won't fail if the gadget name has certain weird things in it):

Code: Select all

if msg:sub(1,#message_identifier) == message_identifier then
    local MsgForMe = msg:sub(#message_identifier + 1)
    --stuff
end
