General scripting issues and questions

[Isaac]

Two New Questions:

Would someone please explain or post an example of the use for 'entitiesAt' ?
What exactly does this function do? (Aside from what's hinted by the name. )

And is what is the way to detect the calling object within the called script?
*Meaning if Button_1 (of several) triggers a script (that they all are connected to), how can the calling button ID be detected?

Two New Questions:

Pick a square with stuff in it and run this script:

Code: Select all

for entity in entitiesAt(1, 17, 16) do
	print("entity is "..entity.name)
   if entity.name == "lurker_hood" then
		do this
	end
end

entitiesAt cycles through everything in the square (level, x, y) so you use it as an iterator in a loop and then you check all the items in that square for something.

Try this:

Code: Select all

for entity in allEntities(1) do
	print("entity is "..entity.name)
end

And it spits out everything in level 1, pretty cool and useful.
When trying to figure something out in a script, put a print line in to see what it's doing.

And is what is the way to detect the calling object within the called script?
*Meaning if Button_1 (of several) triggers a script (that they all are connected to), how can the calling button ID be detected?

I'd like to know this too!

Thank you; that explains it perfectly.

About the calling function ID: I'd like to be able to script some mutually exclusive buttons that could share a common function, but that the function would need to know which one was pushed, and how many times.

petri says this about a new feature:
"- when a script function is triggered it receives the sender of the message as first argument, e.g.
when a button triggers function 'foo' in a script entity, the function receives the button object as its first argument"

Maybe that will help?
also, you could have each button decrement separate counters, and have the script check those counters

I read about the change as soon as it was released. Very cool.

That's exactly what I did; and the script used the calling button as a condition. I used this to script the Potion puzzle from EOB/ level 4; the one where you find the small room with four doors, and inside is a spider, potion, and key.

The puzzle offers you one extra potion if you enter the room from each door, with the rest of them closed; each time you do, you get a potion ~for a total of four.

Another Script Question:
How does one access the contents of an alcove in a script; Is there an iterator for alcoves?

alcoveID:containedItems()

Thanks

I've got another, if any knows: Does the Grimrock editor support labels and...

goto

goto reminds me of my Apple IIe

And reminds me of my TRS-80 and CoCo 1, 2 & 3.

Would someone else please try this code?

Code: Select all

function activate()
dungeon_alcove_1:addItem(spawn("dagger"))
end

I have an alcove in place with the ID "dungeon_alcove_1", and when I run this script... nothing seems to happen; no dagger appears in the alcove; or is that not the way adding items works?
Is there an error in this code?

[petri]

Are you sure the function gets triggered?
