I'm sorry if this seems like a simple question but I've been unable to find the answer so far.
How do I add a hook?
For example, what's the syntax to add an onAttack hook to the party?

Something like:

party.part:onAttack = function( <parameters>...)

doMySpecialThing...

end

Thanks for any help

Instead of feeding you a fish, I will teach you how to fish, and make you a free man, instead of being a slave to others: type onAttack, or onMove, or onDie, in the search box of the forum, and look for examples, there are tens of them here and there.

OK, I tried to search for the term before I posted here.
I can't find an example of how to hook up the function that works in grimrock 2.

I've seen examples of something like this:

Code: Select all

cloneObject{
	name = "party",
	baseObject = "party",

	onAttack = function(self, champion, action, slot)
		hudPrint("Attacking")
	end,
}

added to objects.lua but when I try that I get the following error on dungeon load:

mod_assets/scripts/objects.lua:5: attempt to call global 'cloneObject' (a nil value).

Most of the examples I've seen are from before G2 was released so I assume they are for G1 and the scripting syntax has changed in G2.

Here is one example that will prob. answer all your questions.

That's exactly what I needed.

Thanks!

That's working well but now I have another question.
In Jgwman's scripts, he defines the onAttack hook as follows:

Code: Select all

onAttack = function(party, champion, weapon)
   ...
end

but the scripting reference shows that onAttack has the following signature:

Code: Select all

onAttack(self, champion, action, slot)

I modified the code to use the latter signature and it is called with no errors. However, I'm not sure what is in the 'action' parameter.
type(action) returns 'table' but the following code prints nothing:

Code: Select all

for key,value in pairs(action) do
   hudPrint(key, value)
end

Anyone know which is the correct signature or, if both are fine, what's supposed to be in the action parameter?

Thanks
