How to shorten an Array...

Dad3353

In my current Project (v4.7...), I wish to generously offer to my Player the random opportunity to find a Vaccine against the Poison from one of several Beasts roaming the Dungeon halls. I can construct an Array of Vaccines, in this manner...

var gv_vacc_arra : Array = ["Vacc_Roac","Vacc_Crab","Vacc_Cent","Vacc_Term","Vacc_Bee" etc...]

... for instance. I can have a defeated Beast 'drop' a random Vaccine from this Array upon expiring; my question is...
How may I change the Array contents, removing the already 'dropped' array, so that any 'drop' is for a new, different Vaccine to that already obtained..? One method, which could work but is not ideal, would be to test the random choice, and, if it's already been 'dropped', choose another. This could, in theory, mean a long wait for a drop for the last Vaccines to be chosen. Is there a better way of shortening the Array, removing preceding 'drops'..? Thanks in advance for any viable options or (clean..!) suggestions; meanwhile...
Have a great day.

To answer your question, Godot has a page for every type where it lists what you can do with it. For Array, the page is there: https://docs.godotengine.org/en/stable/classes/class_array.html

I think the method you're looking for is remove_at

Indeed; some looking up, and trying out, produced the solution I was looking for. With both 'remove at' and 'find', I am now able to trim my Array in the manner I need. My Test script worked; I can now incorporate these notions into my Project. Thanks.

var lv_vacc_arra : Array = ["vacc_1","vacc_2","vacc_3","vacc_4","vacc_5","vacc_6"]
var lv_dele_vacc : int = 0

func _run():
	print (lv_vacc_arra) # Print whole Array
	lv_vacc_arra.remove_at(2) # so vacc_3 should go...
	print (lv_vacc_arra) # Print shortened Array
	lv_dele_vacc = lv_vacc_arra.find("vacc_5")
	print (lv_dele_vacc) # Print Array index of candidate (vacc_5...)
	lv_vacc_arra.remove_at(lv_dele_vacc)
	print (lv_vacc_arra) # Print shortened Array

... produces ...
