CanInstallItem Event, or Item Restriction in General

[robotarozum]

This is the very last thing I need to make my mod go, so I hope the answer is easy!

I have a mod ship that I want to only use specific mod weapons, while treating all other installs as in vanilla (so armor restricted by mass, etc.). All the mod weapons have the modifier TDI, so I thought I could accomplish this by doing:

Code: Select all

<Events>
		<CanInstallItem>
			(block nil
			(if
				(or
					(not(eq (itmGetCategory gItem) 4))
					(itmHasAttribute(gItem) "TDI")
				)
				(setq return True)
				(setq return "The Slasher-class only supports TDI weaponry.")
			)
			)
			return
		</CanInstallItem>
	</Events>

To my mind, this makes it so whenever an item tries to install the ship checks to see if it satisfies [not a weapon] or [includes TDI modifier], or else the item can't be installed. What actually happens is... nothing. The event code may as well not exist, as near as I can tell.

This is a relatively recent addition and I can't find any instances of it in github or xelerus, does anyone have experience with it and can point me in the right direction please? Or, is there another way to get at this functionality?

Still have tons of homework to do but tossing this link to you:

Edit: Forget what I said before--it's not a problem with your code.

The problem appears to be a bug in the engine. It doesn't seem to be calling CanInstallItem for devices (only for armor). I can make a fix for the next release. Sorry about that.

[If it's any consolation, at least this will get you into the credits.]

Oh, sweet! Until then I can just politely suggest that people use the appropriate weapons, no problemo.
