Im making a procedural quest, but i don't find a way to build a node with more than 1 parent, is there a way to do that from code?

Here Alchemy Node should be a requirement for success node for example

Hi,

Quests generated using the QuestGeneratorEntity component are linear, such as:

AlchemyWorkshop --> ThroneRoom --> Success

or:

ThroneRoom --> AlchemyWorkshop --> Success

If you're making the quest yourself in the Quest Editor window, link both of those nodes to another node that has a Parent condition:

In the screenshot above, I set the Parent condition to require that all parent nodes (AlchemyWorkshop and ThroneRoom) are true. You could also configure it to require that any one node is true, or any specific number of nodes.

If you're doing this in code instead of using the Quest Editor window, you can do the same using the QuestBuilder class, which works similarly to .NET's StringBuilder class but for quests instead of strings.

Hi, thanks for answering, im using the QuestBuilder from code. Can you give me one example of hoow to make that Condition? so far i just use messageCondition but i don't see any parent condition or similar, how should i build it?

Hi,

Version 1.2.45 will have that method (QuestBuilder.AddParentCondition). Here's a patch for 1.2.44:

QM_QuestBuilderPatch_2024-03-28.unitypackage

Create a node that's linked from the node that you pass it (e.g., AlchemyWorkshop). Then add a link from the other node (e.g., ThroneRoom). Finally, call the new method to add the parent condition.

Hi Tony, today i tried this patch and im a bit lost on how to implement it.

Following the example image you posted.
1) Both True Node has Alchemy node as parent
2) Throne Node and Alchemy has Start as parent
3) i add a Parent Condition to Both True node

Code: Select all

var parentCondition = questBuilder.AddParentCondition(bothTrueNode , ConditionCountMode.All);

4) the builder doesn't include a list of parents, how is that link you mentioned created?

Hi,

I fixed a typo in the patch (above). Please download and import the updated version.

Here's an example script:

Code: Select all

using UnityEngine;

        // Counter parameters:
        public string counterName = "coins";
        public int counterInitial = 0;
        public int counterMin = 0;
        public int counterMax = 3;
        public bool counterRandomizeInitialValue = false;

        // Condition node parameters:

        public string node1ActJournalText = "Find the farmer's coins hidden in containers.";
        public string node1HUDText = "{#coins}/3 Coins"; // {#coins} is a special tag representing the current value of the coins counter.

        // Message node parameters:

            // Then it adds title content, which is a HeadingTextQuestContent object with useQuestTitle set true.
            questBuilder.AddContents(questBuilder.quest.GetStateInfo(QuestState.Active).GetContentList(QuestContentCategory.Dialogue), questBuilder.CreateTitleContent());
            // The remaining lines do the same for Journal and HUD content in the Active and Successful states.
            questBuilder.AddContents(questBuilder.quest.GetStateInfo(QuestState.Active).GetContentList(QuestContentCategory.Journal), questBuilder.CreateTitleContent());
            questBuilder.AddContents(questBuilder.quest.GetStateInfo(QuestState.Active).GetContentList(QuestContentCategory.HUD), questBuilder.CreateTitleContent());
            questBuilder.AddContents(questBuilder.quest.GetStateInfo(QuestState.Successful).GetContentList(QuestContentCategory.Dialogue), questBuilder.CreateTitleContent());

            questBuilder.AddMessageCondition(messageNode, QuestMessageParticipant.Any, "", QuestMessageParticipant.Any, "", "Kill", "Orc");
            questBuilder.AddContents(messageNode.GetStateInfo(QuestNodeState.Active).GetContentList(QuestContentCategory.Dialogue), questBuilder.CreateBodyContent(node2ActDialogText));

            messageNode.childIndexList.Add(questBuilder.quest.nodeList.Count - 1);

            //===== RETURN TO NPC NODE =====

            // Text when active:

            actionList.Add(alertAction);

            // Set the quest indicator to Talk when active:
            var indicatorAction = questBuilder.CreateSetIndicatorAction(questBuilder.quest.id, questGiver.id, QuestIndicatorState.Talk);
            returnNode.GetStateInfo(QuestNodeState.Active).actionList.Add(indicatorAction);

            // Set the Indicator to None when true:
            indicatorAction = questBuilder.CreateSetIndicatorAction(questBuilder.quest.id, questGiver.id, QuestIndicatorState.None);

            questBuilder.AddSuccessNode(returnNode);


            //===== FINISH CREATION PROCESS =====
            // Finally, get the quest:
            Quest myQuest = questBuilder.ToQuest();
            // And add it to the QuestGiver:
            GetComponent<QuestGiver>().AddQuest(myQuest);
        }
    }
}

It's a copy of QuestBuilderExample.cs which is included in Quest Machine, but I added an "Attack Orc" node:

: questBuilderAllParents.png (29.53 KiB) Viewed 1467 times

(A quick way to test the script is to add it to the Village in the Demo scene.)

The key code is:

Code: Select all

//===== PARENT CONDITION NODE =====
var bothParentsNode = questBuilder.AddNode(conditionNode, node3Id, node3Name, QuestNodeType.Condition);
questBuilder.AddParentCondition(bothParentsNode, ConditionCountMode.All);
messageNode.childIndexList.Add(questBuilder.quest.nodeList.Count - 1);

The first line of this code creates a new node linked from conditionNode.

The second line adds an "All Parents True" condition.

The third line links messageNode to this node, too.

Perfect, i make it work with this code, thanks!

Although im having a problem for my particular case. I want the nodes to become active only if the conditions are met, in this case, both parents should be in true state before making the parent condition node active, but with this code when one of the parent nodes is true, the child node is active even with ConditionCountMode.All . Im missing something or cannot avoid this?

Posted: **Thu Mar 28, 2024 3:48 pm**

The parent condition node must be active to monitor the states of its parents. If you want to delay something until after the parents are true, you could either move that into the parent condition node's True state or link the parent condition node to a passthrough node and put the stuff on the passthrough node.

Posted: **Thu Mar 28, 2024 6:45 pm**

Yes, i opted to do a Requirements node before the child node, not the cleanest solution to see but it does the trick. I understand the listening issue there. thanks for the help
