Could someone make a script that lowers a gun's sharplength(by 50) when an attachable is destroyed?

I wanted to have a scope that can be shot off, and once it is, the sharplength will be lowered making so that the scope has a function.

Also, there was one topic that did show up in the search where the author also wanted to know the same thing but there were no answers or rather there was but none that answered the question.

EDIT: Or, you know, someone could at least say what the function name for sharplength in lua is (unless it is exactly that).

I'm pretty sure it's HDFirearm.Sharplength

Thanks CaveCricket, wish they added that to the wiki.

Err, could someone help me out with this?

Edit: fix't

If it isn't read only, you need to make sure it is EXACTLY like it is in the ini files. The variables are case sensitive, etc. Also that script would very quickly reduce the sharplength to very high negatives.

I know it's not read-only, 'cause Coops made an auto-adjust sniper scope zoom a while back.

Also p3l is right. It's SharpLength not Sharplength, and you need to put some kind of safety catch in so that it only reduces sharplength once, or else you'll never be able to aim once the scope is taken off.

So.. The script is mostly fine? Because I kinda just mashed it together...

Also thanks for the tips.

EDIT: Hmm, doesn't seem to work, need to work on it :/ I'd be happy if I can even get it to go to the negative sharplength stage, then I would know I'm going in the right direction.

Not gonna guarantee this'll work but I think it should. You need to stick this on the gun, not the scope, there's some notes below about that.

The only thing I'm not sure of is what this script will do if the scope gets destroyed instead of knocked off. It may crash the game, MovableMan:IsObject(x) doesn't seem to exist so I'm not 100% sure how to make sure it actually exists.

So your biggest problem, aside form Sharplength instead of SharpLenght were the lines
local Parent = ToHDFirearm(HDFirearm) -- Set Parent variable as the parent of the attachable, which is the gun(?)
local Attachable = Attachable("Scope") -- Set "Scope" attachable as the attachable variable
You didn't define HDFirearm before calling ToHDFirearm and that wouldn't have done much anyway. To find the parent you have to search this thing's RootID, that can lead to problems because I can't remember if RootID here will find the gun or the actor holding it. Either way you'd eventually get the gun. As for the second line, you're setting the variable Attachable to be a nonexistent function with the argument "Scope", unless I'm mistaken that does nothing and is probably filling your console with errors.
Aside from that, if you did get the parent properly I'm not 100% sure attachable scripts actually run when they're not attached, I've had some problems with that in the past so I think it's safer to put the script right on the gun.

Hope all this helps, enjoy

First of all, thanks for pointing out the mistakes I made and for making the script. It certainly helps me understand (to a degree) what does what.

Unfortunately though, it doesn't seem to print 'scope found' in the lua console..

What's the preset name of your scope? If it's not Scope then that might be the problem.
But more likely than that is that I ran into the problem I mentioned earlier about finding the parent; namely that it's checking to see if the object's RootID == self.ID. I used this on an actor instead of a weapon, hence the problem. So you need to change

Hopefully that'll do it.

I was about to post my moment of glory to a depressing adventure until I messed around with it again and it worked.

So Bad Boy, I salute you for your help. Twice now.

Edit: errhg actually, something tells me the script works randomly..
Edit: upon further testing I found that it didn't print for the first actor, but it printed for the next 8 actors I called in.
Edit: ok, so heres the problem. If I take control of the craft and open the doors, causing me to auto switch to the actor, the script doesn't work. However, if I let the craft ai drop the actor off, it works.

Yeah, it's this weird thing that CC does, similarly you'll probably have problems if you place it in the base building phase.
Luckily yours doesn't have to delete anything if it's not attached so your fix is pretty simple. Move or copy the scope finding part to the update function, you'll also want to put a line saying self.Scope = nil in the Create to make sure you don't get any errors.

(after several attempts to follow the instructions)
Sorry, where in the update function do I move the scope finding part to and where do I put the self.Scope == nil in the create function.
(Hmm I'm hitting the point where I'm feeling like I'm bothering people, not that I didn't feel like that before..)

No worries, I'm happy to help, particularly since it's not highly time consuming
This here ought to do it.

Many thanks, it works. Just had to change the few things you mentioned before.
