Post subject:  Changing self.Frame for an HDfirearm
I'm trying to make my gun change its sprite when it's reloading, but either the Lua can't change the self.Frame value for HDFirearms, or I'm missing something. Here's the code I've got so far:

Code:
function Create(self)
end

function Update(self)
   if self:IsReloading() then
      self.Frame = 2
   else
      self.Frame = 2
   end
end

I'm pretty sure you are correct. I do not think it is possible to override what frame to use for firearms with Lua.

Can an attachable on a HDFirearm have its sprite changed either?
Even a script for the attachable itself doesn't recognize "self" as valid, unless I'm doing it wrong.

You can change the magazine's frame, but on any weapon that reloads, the mag's naturally absent during that time.
So there's not even a decent work around for tweaking a gun's appearance, it seems. :-(

It would be great if SpriteAnimMode = 0 [don't animate] worked for HDFirearms, and would allow Lua to control the frames.
It'd be helpful for developing future official content too, maybe one of the content devs would be so gracious as to put in a word about it to Data?

You can change the frame of an attachable if the script is on the gun. I didn't know of 'self' not working with attachables, I'll talk to Data about that.

Edit: I just did some testing, 'self' works perfectly fine with scripts on attachables.

I can confirm what CC48 says. I'm working on a script attached to an HDFirearm, and so far everything works fine, can't say I've attempted to change the frame via Lua though.

Okay, I'm trying to make an attachable (assuming I know even an inkling of how to do it), and it's saying that it "could not match property" on the line which I put "FrameCount = 2".

Code:
AddEffect = Attachable
   InstanceName = M249 Top
   Mass = 0
   HitsMOs = 0
   GetsHitByMOs = 0
   SpriteFile = ContentFile
      FilePath = M249.rte/M249Top.bmp
   FrameCount = 2
   SpriteOffset = Vector
      X = 0
      Y = 0
   EntryWound = AEmitter
      CopyOf = Dent Metal Light
   ExitWound = AEmitter
      CopyOf = Dent Metal Light
   AtomGroup = AtomGroup
      AutoGenerate = 1
      Material = Material
         CopyOf = Military Stuff
      Resolution = 4
      Depth = 0
   DeepCheck = 0
   JointStrength = 50
   JointStiffness = 0.6
   JointOffset = Vector
      X = 0
      Y = 0
   DrawAfterParent = 1

Are you using tabs or spaces for your spacing?
Author:  Zaggy1024 [ Mon Jan 23, 2012 9:11 pm ]
Post subject:  Re: Changing self.Frame for an HDfirearm
Tabs. I got the attachable bit of the INI from the wiki which used spaces, though. So that can actually cause an error?

Edit: Okay, it's working (it was because of the spaces, INIs are weird =P)... Now I need to know how to find the attachable from the script in the HDFirearm...

Loop through all MOs, find one that has the PresetName of the attachable and has the same RootID as the HDFirearm.

Post subject:  Re: Changing self.Frame for an HDfirearm
Something like this?

Code:
function Create(self)
   self.TopMO = nil

   for i = 1, MovableMan:GetMOIDCount() - 1 do
      object = MovableMan:GetMOFromID(i);

      if object.InstanceName == "M249 Top" and self.TopMO.RootID == self.ID then
         print('found!')
         self.TopMO = object
      end
   end
end


Currently this doesn't find anything (even with the RootID check not in there).

print should be
Code:
print("found!");

It's probably what's stopping your code from working.

Post subject:  Re: Changing self.Frame for an HDfirearm
No, both ways work fine for printing in the console and in the code...

I tried making it print all the InstanceNames it found, and all of them were nil, so I assume that means there is no property called InstanceName that the Lua can access. Am I right?

Post subject:  Re: Changing self.Frame for an HDfirearm
Wasn't InstanceName a temporal property that can't be read for future references?
You should pick PresetName.

Post subject:  Re: Changing self.Frame for an HDfirearm
Changed it to PresetName (yes, in both the INI and the script), and it's still saying it's nil.

Code:
function Create(self)
   self.TopMO = nil

   for i = 1, MovableMan:GetMOIDCount() - 1 do
      object = MovableMan:GetMOFromID(i);

      if object.PresetName == "M249 Top" then-- and self.TopMO.RootID == self.ID
         print("found!");
         self.TopMO = object;
      end
   end
end


Are you guys sure you can actually access an MO's name from Lua?

Yes. I'm actually working on a mod that stores data in a magazine's PresetName, and it works fine.
