Question

I have a large (size of 10,000) constant Dictionary of Vector2i:int that I am using as a lookup table (the int is an Enum value).

However, having such a large Dictonary loaded in the editor was causing my editor to lag considerably and become unresponsive, so I am trying to serialize/store this constant dictionary into some sort of file and initialize the constant while scripts are being parsed. I found the PackedDataContainer, which claims to be just for effectively storing Arrays and Dictionaries, but there is 0 information I can find on how to retrieve the data once it’s packed.

This Dictionary is programmatically generated from within a tool Scene meant to run while debugging (does NOT use @tool annotation tho. It’s a tool as in it generates this resource for me at debug runtime).

It is literally in the docs:

I already tried that. That doesn’t work for me in the latest version.

It counts up to 10,000 keys which is right, but I cant seem to do much with those keys.

So it works when the keys are strings, but not when they are Vector2i…

Yeah, the documentation states that this only works for string/stringnames. It might be kind of ugly but you could convert your Vector2i to a string.
