I will verify if there is a monster on a tile, I use entitiesAt(level, x, y) but how i see if the iterator is a monster ?
The only possibility I know
Code: Select all
monsters_list = {"snail", "crowern", "wyvern", "other_monster"}
for i in entitiesAt(1,15,15) do
for j in monsters_list do
if i.name == j then
print("monster")
end
end
end
List all monster is laborious, there is no other possibility ?

I wonder if there's a way to list them by class.

All entities have the following properties that can be accessed with the dot operator:
“name” returns the name of the entity
“id” returns the unique identifier of the entity
“x” returns the x-coordinate of the entity on the map
“y” returns the y-coordinate of the entity on the map
“facing” returns the facing of the entity (0=north, 1=east, 2=south, 3=west)
“level” returns the dungeon level index of the entity
No class

I don't know of any other way, but you should only have to do it once, and then you can refer to the list as many times as you need in your dungeon

I had the same problem looking for monsters and other things. The trick is to find a keyword or method that is only attached to the entities in which you're interested. For example, only monsters have the
setAIState method. So if you iterate over the entities returned and eleminate those without this method, you'll have a list of monsters. You might also want to filter on other things like finding all objects in a square - so look only for objects with the
getWeight method. You can look at the entity name too, for example, and find all doors, but finding all monsters or objects without looking at methods is difficult. You can write a dedicated routine for each requirement, but I wrote a generic find and filter routine instead which is found at
viewtopic.php?f=14&t=3985&p=41224&hilit=Lark#p41224 that will do the trick.
To find all monsters, just use
monsters = findAll(self.level, self.x, self.y, {":setAIState"})
See the original post for more details and for the code.
Have Fun!

Thanks for your answers.
I test my script and I have an error :
Code: Select all
for j in monsters_list do attempt to call a table value
I test other simple script with table
Code: Select all
function OpenAll()
list_of_gates = {"portcullis_1", "portcullis_2", "portcullis_3"}
for i in list_of_gates do
i:open()
end
end
and have the same error, why have I the error "attempt to call a table value" ?

The problem here is that you have a table that contains the ids of the entities that you want, but not the entities themselves. Try this (untested) code:
Code: Select all
function OpenAll()
list_of_gates = {"portcullis_1", "portcullis_2", "portcullis_3"}
for i in list_of_gates do
entity = findEntity(i)
if entity ~= nil then entity:open() end
end
end
Good Luck,

P.S. The
FindAll function referenced above returns entities, not ids, so you won't have that problem if you use that function.

Thank you
, but you should replace "infinite genius" with "uncompromisingly stubborn" to get closer to the truth! Hey, I like programming!

If you say so~ haha.
I will continue to revere you as one of the most creative scripters this community's got.
