I will create a proper wiki on GitHub eventually, but for now, here’s a speedrun of the absolute basics:

When creating a quest. create a CounterCreator condition that looks something like the following (expand image):

What’s most important is that the condition itself is impossible to complete; in this case, you are required to kill a pmc from 5555 meters away. This prevents accidental progress on quests. The bottom ‘value’ just under the ‘type’ is important, however, as that will determine how many times your custom condition needs to be met. For example, if you want the player to heal 300 health, set that value to 300.

Keep the id that’s highlighted in mind when we go to the next step. The id in that spot (and only that spot, of the three ids that exist per counter creator) is important.

Create a new .json file and place it in ../BepInEx/plugins/QuestsExtended/Quests. If this new json is anywhere else, it will not be registered. Within this .json, you want something akin to this for each quest (expand image):

The id outside the brackets and the id next to “QuestId” should be the same, and are the id of the quest itself. For each CounterCreator task you have in your quest, create the condition like you see in the image. Remember that highlighted id I mentioned earlier? Place it in the “ConditionId” spot. Check the “Conditions List” tab to see a full list of all custom conditions currently in the mod. The “Locations” can be multiple locations; if you want to have a quest that tracks on Interchange and Customs, but nowhere else, that will work.

Certain quest conditions have additional features. For example, most of the health-related quests can utilize “IncludeBodyParts” (See image below)

When you are creating a release of your mod, I highly recommend you pre-include the .json in its correct path in your download, as that will minimize work on the end user and should prevent complications if the end user downloads your mod first and this one second.

The following is a list of conditions currently in a mod. Some extra comments might be on conditions if they need more explaining. They are separated into “General”, “Combat”, and “Medical” for sorting purposes, but implementing any of them is the exact same: Simply copy the Exact Spelling And Capitalization into the “ConditionType”.

General:

EncumberedTimeInSeconds //If the weight indicator in the inventory is yellow or orange, this will increase.

OverEncumberedTimeInSeconds //If the weight indicator in the inventory is red, this will increase.

MoveDistance //None of the “MoveDistance” tasks are mutually exclusive. If the player is moving quietly while crouched, all three of the conditions will increase

MoveDistanceWhileCrouched

MoveDistanceWhileProne

MoveDistanceWhileSilent //‘Moving Silently’ means the player is moving slow enough to gain CovertMovement experience. Roughly speaking, if the sound icon in the bottom left is in the left third of the bar, this should increase.

SearchContainer

LootItem

ActivatePowerSwitch

CompleteOptionals //See the dedicated “Quests with optional tasks” tab

Combat:

DamageWithAny

DamageWithAR

DamageWithDMR

DamageWithGL

DamageWithLMG

DamageWithMelee

DamageWithPistols

DamageWithRevolvers

DamageWithShotguns

DamageWithSMG

DamageWithSnipers

DamageWithThrowables

DamageToArmour //This tracks the amount of durability lost on the enemy armour.

DestroyEnemyBodyParts //Blacking any body part, including the head or thorax.

KillsWhileADS

KillsWhileCrouched

KillsWhileProne

KillsWhileMounted

KillsWhileSilent //See comment on “MoveDistanceWhileSilent”

KillsWhileBlindFiring

MountedKillsWithLMG

DestroyLegsWithSMG

RevolverKillsWithoutADS //AKA hipfire kills with Revolvers

DamageToArmourWithShotguns

TotalShotDistanceWithSnipers //Every time damage with a sniper rifle is dealt, the distance between the player and the target will be added to this condition. If I hit one bot at 30m and a second at 50m, this condition will be at 80/x. If I then hit someone at 65 m next raid, this task will be at 145/x.

Medical:

FixLightBleed

FixHeavyBleed

FixAnyBleed

FixFracture

HealthLoss

HealthGain

DestroyBodyPart //This means the PLAYER gets a blacked limb, this is not a “destroy limbs on the enemy”. That will be added next update, actually.

RestoreBodyPart //Fun fact: A ‘UseItem’ task set to trigger on the use of either surgical kit will accomplish the same thing.

1.7.5 introduces the “CompleteOptionals” condition, which allows you to create a list of ‘optional’ conditions under one main condition and have the player complete X amount of the ‘optional’s. To create an optional task , you simply add the id of the parent condition to the “parentId” spot when creating the ‘optional’ condition (this is a vanilla feature in Tarkov). The optional tasks may be vanilla conditions or QE conditions, both work. When the player completes an optional objective, only the quest that the completed optional objective is in will increase. In the future, I might add a “CompleteAnyOptionals”, but for now it is only per-quest.

While I have tested this condition a fair amount, it is still experimental. Use with caution.

Create an impossible “AvailableForStart” task (similar to creating an impossible “AvailableForFinish” condition). I recommend a simple “level 99” condition:

Within your custom conditions json, you will need to add some things (click to enlarge):

You will notice that this quest has an extra line defined BEFORE the “condition:[]”: “IsMultipleChoiceStarter”: true. You only need this line if the quest is actually an MCS, it’s assumed false for other quests. Additionally, *most* conditions have an additional thing: “QuestsToStart”: [““]. You made add one or more QUEST Ids to this list, and those quests will automatically be started as soon as the quest is finished (happens before the quest is technically turned in, btw). You will notice that the “CompleteOptionals” itself doesn’t have a QuestsToStart; this is because that condition will always be completed, so any ids you might put there will always be triggered (so if you want a certain quest after this one no matter what, have it unlock normally upon quest completion.) You need to place every condition in a quest that is marked as “IsMultipleChoiceStarter” into this .json. If a specific condition does not start a task, leave QuestsToStart empty for that condition.

You will additionally notice that there is an “Empty” condition type. Use “Empty” if the task is a vanilla condition, and not a QE condition. The reason you need to include the condition in the json is so that your multiple choice quest will actually work.
