Coding problem

[Grimmbart]

Hi

I'm making my first ruleset ans i'have a question :

I create some numberfields like this one (under)

<numberfield name="intelligence_value">
<bounds rect="245,106,24,16" />
<font name="smallcontrol" />
<hideonvalue value="0" />
<description field="intelligence_name" />
<tabtarget>
<next>str_value</next>
<prev>intelligence_name</prev>
</tabtarget>
</numberfield>


Now, i want to create another numberfield, but not editable and with the value " 'intelligence_value' * 2".

How can i do this ?

Help

make another numberfield that has tag
<readonly/>
which sets it to be not-editable

the new numberfield should also have following script:



<script>
function onInit()
int = window.getDatabaseNode().createChild("intelligence_value");
int.onUpdate() = updateValue;
end
function updateValue()
setValue(window.intelligence_value.getValue()*2)
end
</script>


Which makes the new numberfield have value double the intelligence_value.

Thank's, but your script do nothing !!


With this script, the value on screen is OK, but when i update the "intelligence_value", my local control is not updated !!


<numbercontrol name="charge" >
<font name="smallcontrol" />
<bounds rect="513,644,24,16" />
<nodrag />
<nodrop />
<noreset />
<nokeyedit />
<readonly / >

<script>
function init()
local int = window.getDatabaseNode().getChild("intelligence_value").getValue();
setValue(int);end
</script>
</numbercontrol>


Help !!!!!

The first Nuberfield


<numberfield name="Force_valeur" >
<bounds rect="86,226,24,16" />
<font name="smallcontrol" />
<hideonvalue value="0" />
<description field="Force_nom" />
<tabtarget> <next>Charisme_valeur</next> <prev>Dexterite_valeur</prev></tabtarget>
</numberfield>


And here the second field



<stringcontrol name="chargelegere" >
<font name="smallcontrol" />
<bounds rect="110,636,70,16" />
<nodrag />
<nodrop />
<noreset />
<nokeyedit />
<readonly />
<tooltip><text>Valeur de Charge Légère</text></tooltip>

<script>
function update()
local force = window.getDatabaseNode().getChild("Force_valeur").getValue();
local charge = "1kg";

if force == 0 then
charge = "Lavette";
elseif force == 1 then
charge = "0...5 kg";
elseif force == 2 then
charge = "0...12 kg";
elseif force == 3 then
charge = "0...25 kg";
elseif force == 4 then
charge = "0...50 kg";
elseif force == 5 then
charge = "0...125 kg";
else
charge = "Waouuu !";
end
setValue(charge);
end

function onInit()
local force = window.getDatabaseNode().createChild("Force_valeur", "number");
force.onUpdate = update;
update();
end

</script>
</stringcontrol>

And now, it's OK !!

Sorry I forgot the the createChild() function requires to have variable type as second parameter.

int = window.getDatabaseNode().createChild("intelligence_value", "number");

is the correct function calling

Instead of a basic numberfield, you could also use the sources attribute of the modifiernumber template (common_templates). For example: Armour Class in the 3.5e extension (or d20 ruleset).
