3D Game Kit Lite

The 3D Game Kit Lite has been created for teaching purposes and for game developers to create and design levels using the 3D Game Kit without the heavy art or audio Assets. For the full 3D Game Kit find more information here: https://unity3d.com/learn/tutorials/s/3d-game-kit

Making a New Scene

Game commands are a way for GameObjects in your Scene to communicate with other GameObjects, allowing you to add more complex behaviours to your Scene. This communication happens through events in scripts, which you can control via components in Unity. We’ve provided the relevant components for you in this tutorial.

Connecting GameObjects that have Interactables

Opening Doors with Switches

Using Counters and Switches

To finish off the gameplay elements of each Switch, you need to find a way to tell the user what the Switch does, and why it’s important.

InfoZone Prefab

Checkpoints are a common element of most modern games. They allow the player to save their progress, so that if they die, they respawn back at that checkpoint.

Find the Checkpoint

Let’s make a teleportation device, so that Ellen can teleport across the map. We’re going to make a space that Ellen can walk into which teleports them to another location elsewhere in the Scene.

This project gives students everything they need to create a 3D game without using any code. We recommend schools use this lite version of the 3D Game Kit for faster download times.

Games

There’s a Checkpoint Prefab in the GameKit 3D Lite. To find it, go to 3D GamekitLite > Prefabs > Utilities > Checkpoint. 

The Checkpoint is invisible, and Ellen triggers it by walking into the Collider area (the green wireframe box). To ensure that the player knows that they have triggered a checkpoint and knows where they are going to respawn, you should use a visual cue in the game to illustrate that Ellen hit the checkpoint.

In this example, we are going to add another Crystal to the Scene, and set it up so that it activates when Ellen touches a Checkpoint. To do this, we need to place a Crystal and a Checkpoint, and then set the Checkpoint up so that when Ellen touches it, it sends a Game Command to the Crystal.

Drag and drop the Checkpoint Prefab into the Scene and place it to ensure that Ellen can touch the Collider.

Resize it to make sure it only covers the area you want to include.

In the Inspector window, Set the Layer setting to Checkpoint.

Go to 3D GamekitLite > Prefabs > Interactables and drag a Crystal Prefab into the Scene. Place it near the checkpoint area and rename it to CheckpointCrystal.

To link the two GameObjects, select the Checkpoint.

Add Send On Trigger Event (type it in the search box to find it).

Apply the following settings to the Send On Trigger Event component:

Set Interactive Object to GateCheckpoint via the GameObject selection.

Set Layers to Player. This allows the play character (Ellen) to collide with the area.

To verify the connection between them, select the CheckpointCrystal, view the Inspector window to check that the Game Command Receiver has Checkpoint listed in the Senders list.

To test the checkpoint, press Play and walk into the Checkpoint. The CheckpointCrystal now should activate. Next, test what happens if she dies. She should respawn in the center of the Checkpoint volume.
