Continue to different nodes programatically based on condition.

[jlhacode]

Hi. I have a Success and a Fail node after showing a puzzle. A Success() function gets called if the user succeeds, and vice versa. What would be the best practice way to enter the correct node in each respective method? My continue Continue Button is set to "Always", which might be giving me problems, but I'm not sure.

Hi,

If the puzzle is part of the conversation, such as a riddle, then two links will be helpful:

• Conversation Conditions Tutorial
• Special Note: Conversations Evaluate Conditions One Extra Level Ahead

If the puzzle happens externally from the conversation, and the conversation stays active but waits until the puzzle is done, then you can do something like this:

1. In a dialogue entry node, tell the conversation to wait until it receives a sequencer message. You can choose the message string; it's arbitrary. Maybe something like:

• Sequence:

  Code: Select all

  SendMessage(Open,,Puzzle); // Call the Open() method on scripts on Puzzle GameObject
  WaitForMessage(DoneWithPuzzle) // Stay on this node until message "DoneWithPuzzle"

2. In the Success() function, set a Dialogue System variable and send the sequencer message:

Code: Select all

void Success()
{
    DialogueLua.SetVariable("SolvedPuzzle", true);
    Sequencer.Message("DoneWithPuzzle");
}

3. In the Failure() function, set a Dialogue System variable and send the sequencer message:

Code: Select all

void Success()
{
    DialogueLua.SetVariable("SolvedPuzzle", false);
    Sequencer.Message("DoneWithPuzzle");
}

4. Add an empty node after the node above. (See the 'Conversations Evaluate Conditions One Extra Level Ahead' note.) Set the Sequence to "Continue()" to simulate a continue button click and automatically move past the node.

5. Link the empty node to two nodes, each of whose Conditions fields checks the DS variable and goes down the success or failure path.

The solution mostly works, except for one hiccup. The dialogue doesn't progress forward automatically when the puzzle is finished, even after adding a WaitForMessage(Answered) sequence to the node that launches the puzzle. I'm calling Sequencer.Message("Answered"); in the success method.

If you're using continue buttons, change:

Code: Select all

WaitForMessage(Answered)

to:

Code: Select all

Continue()@Message(Answered)

Perfect solution, thank you sir!

Glad to help!
