# Quick Setup The quick setup guide covers how to get a time trial system working in your project with minimal setup. This section makes use of the pre-packaged [TTSystem ](https://llando.gitbook.io/ttsystem/components-prefabs/ttsystem)prefabs to automatically handle a lot of the process. It uses terminology that describes adding time trials to racing games, but the implementation steps are largely the same for all genres. E.g: platformers, speedrunning, puzzle games etc. Should you want more customizability when integrating into your own project, refer to the [Manual Setup](https://llando.gitbook.io/ttsystem/guides/manual-setup) guide. This guide assumes that you have already imported the **Complete Time Trial System** package into your project. {% hint style="info" %} **NOTE:** The minimum 3 components needed to setup time trials are the [TrackManager](https://llando.gitbook.io/ttsystem/components-prefabs/trackmanager), [LapTimeTrackingObject ](https://llando.gitbook.io/ttsystem/components-prefabs/laptimetrackingobject)and the [TrackPoint ](https://llando.gitbook.io/ttsystem/components-prefabs/trackpoint)components. The quick setup guide uses a prefab that adds all of these automatically but it is still useful to be aware of. {% endhint %} ### Video Guide: {% embed url="" %} ### Step-by-step: * Add a [LapTimeTrackingObject](https://llando.gitbook.io/ttsystem/components-prefabs/laptimetrackingobject) component to any object(s) that you wish to track lap times of. The object that you add this component to **MUST** have a collider and rigidbody attached. * Drag one of the two [TTSystem ](https://llando.gitbook.io/ttsystem/components-prefabs/ttsystem)prefabs found in **TTSystem > Prefabs** into your scene. * If your [LapTimeTrackingObject ](https://llando.gitbook.io/ttsystem/components-prefabs/laptimetrackingobject)uses 2D colliders, use TTSystem2D prefab. * If your [LapTimeTrackingObject ](https://llando.gitbook.io/ttsystem/components-prefabs/laptimetrackingobject)uses 3D colliders, use TTSystem3D prefab. {% hint style="warning" %} **CAUTION:** Collider types of [LapTimeTrackingObject ](https://llando.gitbook.io/ttsystem/components-prefabs/laptimetrackingobject)and TrackPointPrefabs must match for OnTriggerEnter/OnTriggerEnter2D callbacks to be registered which is required to calculate lap times. {% endhint %} * Within the root [TTSystem ](https://llando.gitbook.io/ttsystem/components-prefabs/ttsystem)prefab there are five [TrackPointPrefabs ](https://llando.gitbook.io/ttsystem/components-prefabs/trackpoint)inside the ExampleTrack parent GameObject, either 2D or 3D depending on the [TTSystem ](https://llando.gitbook.io/ttsystem/components-prefabs/ttsystem)you selected. These are used as various points along your track - you can think of them as checkpoints. * Move the position of each [TrackPointPrefab ](https://llando.gitbook.io/ttsystem/components-prefabs/trackpoint)GameObject to positions along your track and in the correct order you want them to be passed in. * Adjust the dimensions of any [TrackPointPrefab ](https://llando.gitbook.io/ttsystem/components-prefabs/trackpoint)colliders if needs be so they fit your track. * In the ExampleTrack GameObject, navigate to the [TrackManager ](https://llando.gitbook.io/ttsystem/components-prefabs/trackmanager)component and: * Set the TrackType parameter on the [TrackManager ](https://llando.gitbook.io/ttsystem/components-prefabs/trackmanager)to either linear or circular based on the layout of your track. (See [TrackManager](https://llando.gitbook.io/ttsystem/components-prefabs/trackmanager) for a breakdown of each type of track). * **(Optional)** Set the track name field to the name of your track. * **DONE!** Complete a lap with your [LapTimeTrackingObject](https://llando.gitbook.io/ttsystem/components-prefabs/laptimetrackingobject). Time trial data will now be displayed on screen as part of the [TTSystem ](https://llando.gitbook.io/ttsystem/components-prefabs/ttsystem)in the [TimeTrialUIManager ](https://llando.gitbook.io/ttsystem/components-prefabs/timetrialuimanager)GameObject. This can be deleted/hidden if you do not want your time trial data on screen as all time trial data is still exposed on the [LapTimeTrackingObject ](https://llando.gitbook.io/ttsystem/components-prefabs/laptimetrackingobject)component. Navigate to the [LapTimeTrackingObject ](https://llando.gitbook.io/ttsystem/components-prefabs/laptimetrackingobject)component while your game is running to see the time trial data in real-time without requiring any UI in your game. This is useful for debugging and is updated live as you complete the lap. ### Modifying The TTSystem Prefab To Suit Your Track You can add/remove [TrackPointPrefabs ](https://llando.gitbook.io/ttsystem/components-prefabs/trackpoint)as you need, but **ALWAYS** update the TrackPoints list in the [TrackManager ](https://llando.gitbook.io/ttsystem/components-prefabs/trackmanager)and populate the list in the order you want them to be passed as seen in ExampleTrack: | TTSystem Hierarchy | TrackManager Component on ExampleTrack | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | ![](https://3733049803-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FKSO40gSd5fO9KWfOWErW%2Fuploads%2FqBmIAgfWtZ0PpJL4vNiq%2Fimage.png?alt=media\&token=a01599de-f0b1-4e8d-9970-6dda774346ca) | | {% hint style="info" %} **BEGINNER UNITY TIP:** You do not have to individually drag each GameObject into the inspector to populate a list: * Make sure your [TrackPointPrefabs ](https://llando.gitbook.io/ttsystem/components-prefabs/trackpoint)are in order * Lock the inspector with the [TrackManager ](https://llando.gitbook.io/ttsystem/components-prefabs/trackmanager)component visible * Select the [TrackPointPrefabs ](https://llando.gitbook.io/ttsystem/components-prefabs/trackpoint)for that track * Drag the entire selection into the list of TrackPoints to automatically populate it whilst maintaining the correct order. {% endhint %} ### What Next? #### [How do I make time trial data save across game sessions?](https://llando.gitbook.io/ttsystem/guides/adding-time-trial-saves) #### [How do I add time trials to multiple tracks?](https://llando.gitbook.io/ttsystem/guides/adding-new-tracks)
