Hello,
I am trying to build a behavior tree with an "Attack" which is conditional on "Is Lua True". I cannot find the right syntax to check the Lua variable.
I want the AI to attack only if the Lua variable (bool) is true.
E.g. the Lua variable => "player_alive" = true (default as set in the Dialogue Database / Variables)
How should I write the Lua Code in the Behavior Tree? I tried with "player_alive" or "Variable["player_s5duel"]", but it doesn't work.
I have attached the Lua bridge to the AI character
Thank you!

Hi,
You shouldn't need the bridge for Is Lua True.
The syntax to check if the Dialogue System variable "player_alive" is true is:

The syntax to check if the Dialogue System variable "player_alive" is true is:
Code: Select all
Variable["player_alive"] == true

Hi Tony,
thank you for your reply. I tried using this syntax
in the Inspector / Lua Code section of the Behavior Designer Tree (see attached), but I get that the "Lua code is null or empty".
Could you confirm that my approach is correct?
1- I start with the variable "player_alive" = true (setup in the Dialogue database)
-> the AI should attack
2- if, conditional to some action, I set the variable to false in a script: DialogueLua.SetVariable("player_alive", false);
-> the AI should not attack

Re: Behavior Designer - Is Lua True
Hmm, that error is strange, since I see that the Lua Code field has code. From everything you described, you're doing it correctly. Is the error maybe coming from a different behavior tree or a different task node?
Can you send a reproduction project to tony (at) pixelcrushers.com?

Hi Tony,
I tried again and now it works. The only difference is that I wrote the code instead of just copy pasting...it doesnt make much sense but at least it looks fine
Thank you for your support!

Very strange! Glad it's working now.
