I have var arr = Array()
How can I iterate all objects of this array with access to their funcs?

I can’t test it right now but I guess it’s something like

var arr = Array()
# populate the array
for item in arr:

Or this if you need the index:

for i in range(0, arr.size():
    print("Accessing item at index " + str(i))

You can iterate over arrays with a for loop: GDScript reference — Godot Engine (latest) documentation in English
You can’t store functions in variables or arrays in GD script but you can reference them:

# Call a function by name in one step"myfunction", args)

# Store a function reference
var myfunc = funcref(mynode, "myfunction")
# Call stored function reference

First, note that you can build your array using the Inspector:

export var arr = ["obj_1", "obj_2"]

You’ll be able to change the variable type in the inspector.

Then, you will have to loop in your array using while or for.

#loop in arr
var i = 0
while i < arr.size():
    #Access func

    #Acces or change var
    arr[i].var_name = 1

    #Then iterate to avoid infinite loop!!
  1. First be sure they all have the same scripts, or at least the same func name!
  2. Looping in large array and accessing their funcs can get your game laggy
  3. Avoid death loops! (Always add i+=1 in the loop)
