Hey!
i want to read the value of a key from a dictionary using a for loop. is it possible to do this with a variable instead of using the name of the key?
onready var items = get_tree().get_nodes_in_group("item")
var vitem = {}
func _ready():
set_fixed_process(true)
func _fixed_process(delta):
for i in items:
var name = i.get_name()
vitem = {name:0}
for i in vitem:
if vitem.i > 0:#######################
print(i)
var pic = get_node("items/"+str(i))
pic.set_pos(Vector2(0,0))
The problem is in the line with the quotes. i also tried vitem.i.value() and stuff, but it don’t work.
thank you very much!
Scratch first comment.
If you want to access a key via a string variable, you can do something like this:
var dict = {}
dict.a0 = {name = "yours", num = "100"}
dict.a1 = {name = "mine", num = "101"}
for i in range(dict.size()):
var key = "a" + str(i)
print(dict[key])

thank you.
but if i do it with equals sign its not possible to write a variable as key.
var name = i.get_name()
vitem = {name:0}
print(i)
output is “seed” - which is the name of the object
var name = i.get_name()
vitem = {name = 0}
print(i)
output is “name”.
is there a way to easily write and read it?

Sorry, I’m misunderstanding what you’re trying to accomplish.
avencherus | 2017-02-09 00:54
Are you meaning to do something like:
for value in vitem.values(): print(value)
avencherus | 2017-02-09 00:58
sorry, maybe i should explain.
im working on an inventory. i have a group named “item”. the script should write a dictionary with all the objects in the group with a starting value of 0. (first loop)
for i in items:
var name = i.get_name()
global.vitem[name] = i.value
the second loop should check if there is an entry in the dictionary with a value > 0. and finally it should place this object in an inventory slot.
Edit:
Just saw your second post. its getting close to what i need. but i totally need the connection between key and value… means that i need to access the value when i have the key or the other way.

Well the ways I would loop through it would be one of these two choices:
for value in vitem.values():
print(value)
if(value > 0): print("greater than 0")
for key in vitem:
printt(key, vitem[key])
if(vitem[key] > 0): print(key + " is greater than 0")

this is exactly what i wanted!
thank you very much!

You’re welcome. I’ll post that as the answer for others then.
