How to store a common number that all players can change

[feldrol]

Hi,
I have nearly finished the ruleset I have been working on during the last few weeks. There is one thing missing and I don't know where to start.
In that game the players can draw points from a common pool of points to improve their actions.
Is there a way to have this working on FG?
From what I saw up to now, from a server side (player) you cannot change databasenodes belonging to other players.
I saw the same thing thing with combattracker related nodes.
Where/how should I store a data (number) in the database so that everyone can have read/write acess to that databasenode ?

Any hint welcome :-)

Hi feldrol that is also my understanding... only the databasenode owner can edit the entry.... I think you will need Moon Wizard on this one!

Ok, so I'll try my first summon Moon Wizard spell :-)

You'll need some kind of interface for the players to use that doesn't directly access the database node holding the point total. e.g. like dragging a token off a stack or a number interface that they enter how many points to use then press a button. In the second example (enter a number and press a button) the code will then use OOB (out of bounds) messaging to kick off code on the GM side. Code running on the GM side can modify the database node.

A simple example is to have a look at the AFK OOB code in the CoreRPG ruleset, desktop\scripts\characterlist.lua.

You could also use the OOB message processing on the GM side to write a message to the chat window for all to see. For example, "Trenloe has used 5 luck points."

I would suggest something exactly along the lines that Trenloe suggested.

Use the OOB messages to have the player clients notify the host when the pool should be adjusted. I would also agree that handling all the message notifications on the GM side would be easiest as well.

Ok, thanks for the advice.
I'll try staring from the OOB example in characterlist.lua

So I have something that is nearly working.
I declared my "kigroupe" number, from which every player will draw ki points in the ct_host.xml :



<sheetnumberl5r name="kigroupe">
<anchored to="headeranchor" position="insidetopright" offset="35,-30" width="20" />
<script>
function onInit()
OOBManager.registerOOBMsgHandler("kigroupe", handleKiGroupe);
end

function onValueChanged()
CHARSHEET = "charsheet";
nCT = DB.findNode("combattracker");
local tempkigroupe = DB.getValue(nCT,"kigroupe",0);
for _,v in pairs(DB.getChildren(CHARSHEET)) do
DB.setValue(v,"kigroupe","number",tempkigroupe);
end
end

function handleKiGroupe(msgOOB)
local rMessage = {font = "systemfont", text = "", secret = false};
nCT = DB.findNode("combattracker");
local tempkigroupe = DB.getValue(nCT,"kigroupe",0);
DB.setValue(nCT,"kigroupe","number",tempkigroupe-1);
rMessage.text= msgOOB.user .. " utilise un KI de groupe";
Comm.deliverChatMessage(rMessage);
end
</script>
</sheetnumberl5r>


In my charsheet_main.xml I have declared a field that updates with the value of the "kigroupe" pool:


<number_charskillfield_static name="kigroupe">
<anchored>
<to>reaction</to>
<position>insidetopleft</position>
<offset>105,90</offset>
<size>
<width>20</width>
<height>20</height>
</size>
</anchored>
<script>
function onInit()
local nkigroupe = DB.getValue(DB.findNode("combattracker"),"kigroupe",0);
self.setValue(nkigroupe);
end

</script>
<disabled/>
</number_charskillfield_static>


I have a button that fires the message handler, also in charsheet_main :


<button_actionsdown name="ki_remove">
<anchored to="reaction" position="insidetopleft" offset="135,90" width="20" height="20" />
<script>
function onInit()

end

function onValueChanged()
local msgOOB = {};
local sUser = User.getUsername();
msgOOB.type = "kigroupe";
msgOOB.user = sUser;
Comm.deliverOOBMessage(msgOOB);
end

</script>
<tooltip text= "decremente le ki de groupe" />
</button_actionsdown>


Everything works fine (my pool is decreased on the combattracker and the field on the charsheet_main is updated when I press the button) but on the client side I have the error message :
[ERROR] Unknown special message type received. (kigroupe)
So the handler fires on the host side, but also on the client side.
I tried to declare :
"OOBManager.registerOOBMsgHandler("kigroupe", handleKiGroupe);" in the onInit of the "ki_remove" button with a handleKiGroupe function in this button that does nothing, but then the host handler is not firing.

What am I doing wrong ?

[Trenloe]

This could be because the script scopes are across multiple control script blocks.

Move all of the OOB messaging to a global script package (like the example I mentioned in coreRPG).
