[Question] How to get Vessel ElectricCharge Total?

[ChaseHQ]

How do I go about retrieving the ElectricCharge Total for the current Vessel?

I've kinda taken it from the ResourceDisplay by the following Method.

var ElecQuery = from item in ResourceDisplay.Instance.resourceItems where item.nameText.text == "ElectricCharge" select item;
                _ElectricResource = ElecQuery.First();

Within the ResourceItem is the vesselResourceCurrent and vesselResourceTotal, but I can not grab it until the resource display has been shown. There has got to be a better way to get the information about Resources.

Thanks in advance!

The plugins i have seen doing sth like that are simply looping though all parts and sum them up. Duno if there is any better solution.

This is how I do it. Like Faark said, just iterating through all the parts and looking at the electrical charge in it.

double electricCharge = 0;
double electricMax = 0;
Vessel active = FlightGlobals.ActiveVessel;
foreach (Part p in active.parts)
{
     if (p.Resources.Contains("ElectricCharge"))
     {
          foreach (PartResource pr in p.Resources)
          {
               if (pr.resourceName.Equals("ElectricCharge"))
               {
                    electricCharge += pr.amount;
                    electricMax += pr.maxAmount;
                    break;
              }
         }
    }
}

Efficiency bit: ditch the if...Contains. You're doing the same loop twice there.

[ChaseHQ]

Yup, ended up doing it this way, just feel so inefficient rolling a loop every update. And numerobis you need the if as a part can contain multiple resources, this singles out just electriccharge.

[Trueborn]

Good point numerobis.

KethaneGenerator does this:

var resources = Misc.GetConnectedResources(part, "ElectricCharge");
var ratio = resources.Sum(r => r.amount) / resources.Sum(r => r.maxAmount);

Misc.GetConnectedResources is just a convenience wrapper for Part.GetConnectedResources(). This works for other resources, too, and will only look at resources that can be accessed through a RequestResource call.
