So I am currently testing out a dialogue system that I have made a few days ago. All was good until today when I tested it again. Whenever I click the overhead button on a NPC, the dialogue UI does not show up, instead there was an error in the output which was:
[14:26:02.850 - ReplicatedStorage.RobloxDialogue.Class.Graph:23: attempt to index local 'initialPrompt' (a nil value)]
Yesterday this error did not happen at all, it was very smooth but it appeared today. I checked my graph script which was where the error came from and so far there was nothing wrong. The code below is a snippet of the full code as these few lines was where the error came from
[14:45:42.692 - Plugin_2921269188.Plugin.Data.Class.Graph:23: attempt to index nil with 'IsA']
This error occurs whenever I try to open the editor. I have no idea why this error appeared.
All code is from the dialogue editor plugin
Code Snippet
local Super = require(script.Parent)
local Graph = Super:Extend()
function Graph:OnNew()
self:InitInitialPrompts()
end
--//-------------------//--
--//--class variables--//--
--//-------------------//--
--Prompt[] InitialPrompts
--* list of the possible initial prompts for this entire tree.
--* they are ordered by priority and the first valid one is chosen.
Graph.InitialPrompts = {}
function Graph:InitInitialPrompts()-- The line where the first error came from
self.InitialPrompts = {}
end
function Graph:GetInitialPrompts()
return self.InitialPrompts
end
function Graph:AddInitialPrompt(initialPrompt)-- The line where the second error came from
if not initialPrompt:IsA(self:GetClass"Prompt") then
error("Attempted to add a non-Prompt to Graph.")
end
