Gadget and Widget Cross Communication

[bobthedinosaur]

So.... Lets say I have a trigger/ condition that changes a local in one gadget. How can I get other gadgets and widgets to see this?

[knorke]

there is a tablething GG that all gadgets can read, you need to put your variable in it.

http://answers.springlobby.info/questio ... munication

probally good idea to use GG.dinobob.bla instead of just GG.bla to avoid conflicts with other widgets.

[bobthedinosaur]

muhahahahahahahaha


YES!

[CarRepairer]

But you also want widgets to see it so GG won't work. You might want to instead use Spring.SetGameRulesParam(...) which can then be ready by widgets as well.

[knorke]

isnt there WG? (not sure)

[CarRepairer]

Yes there's WG, but that's only for widgets. Bob wants both to to communicate from gadget to gadget/widget.

a trigger/ condition that changes a local in one gadget. How can I get other gadgets and widgets to see this?

[bobthedinosaur]

how do i do

Spring.SetGameRulesParam(...)

??

[Google_Frog]

This gadget and this widget have gadget -> widget communication.

The important bits*


Gadget synced (anywhere in synced)

Code: Select all

SendToUnsynced("MexEnergyEvent", teamID, allyTeamData.teams, energyWasted, ODenergy,summedMetalProduction,summedOverdriveMetal, teamEnergy[teamID].totalChange, teamIncome)

Gadget unsynced

Code: Select all

function WrapToLuaUI(_,teamID, allies, energyWasted, energyForOverdrive, totalIncome, metalFromOverdrive, EnergyChange, teamIncome)
  if (teamID ~= Spring.GetLocalTeamID()) then return end
  if (Script.LuaUI('MexEnergyEvent')) then
    Script.LuaUI.MexEnergyEvent(teamID, allies, energyWasted, energyForOverdrive, totalIncome, metalFromOverdrive, EnergyChange, teamIncome)
  end
end


function gadget:Initialize()
        gadgetHandler:AddSyncAction('MexEnergyEvent',WrapToLuaUI)
end

Widget:

Code: Select all

function MexEnergyEvent(teamID, allies, energyWasted, energyForOverdrive, totalIncome, metalFromOverdrive, change, teamIncome)
  if (Spring.GetLocalTeamID() == teamID) then 
        WG.energyWasted = energyWasted
        WG.energyForOverdrive = energyForOverdrive
        WG.change = change -- energy change by OD - substract that from income 
        WG.mexIncome = totalIncome-metalFromOverdrive
        WG.metalFromOverdrive = metalFromOverdrive
        WG.teamIncome = teamIncome
        WG.allies = allies
  end
end

*Lua may contain missing localisations and includes

[bobthedinosaur]

okay
what am i doing wrong here
from gadget synced section

Code: Select all

local function NextRound()
	if curround < maxrounds then
		curround = curround + 1
		SendToUnsynced("RoundReset", curround)
		DisplayScore()
		echo( '-- Round ' .. curround .. " --" )
		KillAll()
		KillDead()
		SpawnGear()
		MakeAllWatchersBlind()
		SpawnStarters()
	else
		--Game Over
		gameover = true
		KillLosingAlliances()
		DisplayScore()
	end
end

and widget:

Code: Select all

function RoundReset(curround)	
		if ((curround ~= nil) and (curround > lastround)) then
		lastround = curround
			local x, y, z = Spring.GetTeamStartPosition(Spring.GetMyTeamID())
			local unitArray = Spring.GetTeamUnits(Spring.GetMyTeamID())
			if (unitArray and #unitArray==1) then
			  --Spring.SelectUnitArray(unitArray[1])
			  Spring.SelectUnitArray(unitArray)
			  x, y, z = Spring.GetUnitPosition(unitArray[1])
			end
			if x and y and z then
			  Spring.SetCameraTarget(x, y, z)
			end
		end	
	--end
end

By the look of it you didn't look at the central codeblock of my last post.

[bobthedinosaur]

Lies! This doesn't work.. I'll get echos saying the lauUI script is found, but the local is always nil and never comes out of sync to unsync.

Gadget parts:

Code: Select all

...
local function NextRound()
	if curround < maxrounds then
		curround = curround + 1
		DisplayScore()
		echo( '-- Round ' .. curround .. " --" )
		SendToUnsynced("NewRoundNotice", curround)
		KillAll()
		KillDead()
		SpawnGear()
		MakeAllWatchersBlind()
		SpawnStarters()
	else
		--Game Over
		gameover = true
		KillLosingAlliances()
		DisplayScore()
	end
end

Idk, get the CA gadget and widget pair and delete things from both that look unimportant until it stops working.

[SirMaverick]

in widget: move Initialize() after your NewRoundNotice(). I remember there were problems with ordering of functions, e.g. could be nil if it is defined later.

[bobthedinosaur]

Good idea, but it didn't help. Still only getting nil.

okay.. I'm getting this in the log for my echos in the gadget section.

[ 2497] looking for luaUI w round, NewRoundNotice <<--echo in gadget: "Spring.Echo("looking for luaUI w round", curround)"
[ 2497] Found luaUI <<--echo in gadget
[ 2497] Round called, NewRoundNotice <<--- echo in widget " Spring.Echo("Round called", curround)"

does this mean that the gadget is trying to send "NewRoundNotice" as a curround value?

?

[jK]

Why the heck didn't you posted the output right next to your widget???
Oh yeah it makes so much fun to search errors w/o getting any hints ...
NEXT time post ALWAYS the (including error) messages when you expect help!

SO your arguments declaration in the widget are wrong. Replace "NewRoundNotice(curround)" with "NewRoundNotice(...)"
and add a "Spring.Echo(...)" to get+see all arguments. Their values may indicate what you are searching for.

k the error is earlier in the pipe

Code: Select all

function RoundNotifier(curround)
	Spring.Echo("looking for luaUI w round", curround)
	if (Script.LuaUI('NewRoundNotice')) then
	Spring.Echo("Found luaUI")
	Script.LuaUI.NewRoundNotice(curround)
	end
end
	
function gadget:Initialize()
Spring.Echo("sent to unsync w round", curround)
	gadgetHandler:AddSyncAction('NewRoundNotice',RoundNotifier)
end

the arguments of RoundNotifier(curround) are wrong, add here the "..." to see all arguments and select the correct ones.


PS: it is even visible in the log

[ 1729] -- Round 2 --
[ 1729] looking for luaUI w round, NewRoundNotice

From the code you wanted to see a number there and not the function name .

PPS: k, you even noticed that, just didn't knew how to handle such errors ^^

[bobthedinosaur]

okay. I now know what was wrong. if you notice my code in the unsync portion of the gadget i do not include a _, at the begging of the function and so it was sending the function name instead of the value...

thanks for every ones help and patience!

[bobthedinosaur]

Something that was never really discussed earlier in this old thread. Widget to gadget communication, how would one set that up?

Say I wanted to send the user's playerID along with some other data to a gadget.
