[SOLVED] Resource Manipulation Help

[jandcando]

I have started writing my first plugin for my mod, Impossible Innovations, and I'm adding intakes for collecting hydrogen and a converter for converting it into deuterium or tritium. But I ran into a problem:

Everything works perfectly, but I have been manipulating resources with:

public override void OnUpdate()
{
base.OnUpdate();

this.part.RequestResource("Hydrogen", -1);
}

But the code above is highly dependent on the set Delta Time and it is not affected by time warp. Also, when using physical time warp the rate goes down by a factor of 2 for each warp step.

I want to know how to manipulate resources based on ingame-seconds, not delta seconds. Can anyone help me out on this?

NOW its solved

(-X * Timewarp.fixedDeltaTime) is what you want (where X is units per second of UT), and you need to do this in OnFixedUpdate (which is done per tick) rather than OnUpdate, which is done per visual frame.

Ok I'll give that a try!

So this is what I need to do if I want 1 hydrogen per second?

public override void OnFixedUpdate()
{
     this.part.RequestResource("Hydrogen", Timewarp.fixedDeltaTime * -1f);

     base.OnFixedUpdate();
}

This code isn't being called for some reason, though.

PartModule-derived class, or a KSPAddon?

If the former make sure it's been Started by KSP (and is active). If the latter, use FixedUpdate().

(That code looks correct to me, for a module)

It's a PartModule extension, and it worked when it was called OnUpdate(), but when I call OnFixedUpdate() it just gets ignored from what I can tell. I'm going to keep experimenting with this.

Oh I found what the problem is! I need to call part.forceactivate() so that the part is active when the flight loads. Apparently OnFixedUpdate isn't called unless the part is active.

Except that activates every PartModule on the part. Not a good practice. Just use FixedUpdate(), you won't need to to that. You'll just need to add something like "if (!HighLogic.LoadedSceneIsFlight) { return; }" at the top but that's all.

I don't see any documentation for FixedUpdate(). If you actually meant OnFixedUpdate, I tried that and it didn't work unless the part was activated.

I'm new to KSP modding, soo sorry if I'm being ignorant right now...

[NathanKell]

OnFixedUpdate is run by KSP, only when the part is active (and only works on PartModule-derived classes).

FixedUpdate is run by Unity, always.

Ok that should simplify my code greatly. Thanks!

I tried this:

 public override void FixedUpdate()
        {
            if (intakeActive == "Active")
            {
                part.RequestResource("Hydrogen", ((this.part.vessel.atmDensity * -1.4f) - 0.01f) * TimeWarp.fixedDeltaTime);
            }
        }

This code produced the error:

'ImpossibleInnovations.ModuleIIHydrogenIntake.FixedUpdate()': no suitable method found to override

Am I missing a reference? I have Assembly-CSharp.dll and UnityEngine.dll referenced already.

[NathanKell]

nothing to override; just use public void FixedUpdate

Wow thanks! Everything seems to be working now. I appreciate the help.

My pleasure!
