inside my main c# script i have the following property:
public Dictionary<Vector3, List<long>> RenderDict = new Dictionary<Vector3, List<long>>();
on another node that also uses c#, im trying to get this dictionary like so:
Node chunk = GetParent().GetParent();
Dictionary<Vector3, List<long>> Rd = (Dictionary<Vector3, List<long>>)chunk.Get("RenderDict");
both Scripts have using System.Collections.Generic; at the top of the script. this is the error i receive:
CS0030: Cannot convert type 'Godot.Variant' to 'System.Collections.Generic.Dictionary<Godot.Vector3, System.Collections.Generic.List<long>>'

the only way to "fix" this error is to use the following:
Godot.Collections.Dictionary Rd = (Godot.Collections.Dictionary)chunk.Get("RenderDict");
but this is undesirable because it also turns all the components stored inside the dictionary into Godot.Variants as well.
foreach (Vector3 i in Rd.Keys)
{
List<long> list = (List<long>)Rd[i];
}
using this on the Godot.Collections.Dictionary Rd causes the following error:
CS0030: Cannot convert type 'Godot.Variant' to 'System.Collections.Generic.List<long>'

how do i cast a type on the acquired data from the Godot.Collections.Dictionary? or how do i get the original RenderDict without it turning into a Godot.Variant? this issue is also prevalent when trying to Set the value from the original node:
GetChild(0).GetChild(1).Set("Rd", RenderDict);
the error:
CS1503: Argument 2: cannot convert from 'System.Collections.Generic.Dictionary<Godot.Vector3, System.Collections.Generic.List<long>>' to 'Godot.Variant'

any help in this regard is very much appreciated. Thank you in advance!

  • Better to leverage C# here rather than using godot methods to Get attributes and/or properties. e.g.

        YourScriptClass chunk = GetParent().GetParent() as YourScriptClass; // your main script type here
    Dictionary<Vector3, List<long>> Rd = chunk.RenderDict;
    /* ... */

    Or just use the public property directly, etc.

    (I don't know what your main script's class is called, change YourScriptClass accordingly).
