Introduction to Quick Start Guide

Let’s begin by creating a New Scene. We have made a tool that can create a scene with everything you need to have some ground and Ellen, our hero, able to run around and attack.

Your new Scene will show ground, Ellen, some UI and Game Menus.

The controls for Ellen (our player character) are as follows:

Making a New Scene

We’ll be adding a moving platform to our scene. All interactables are in

Let’s make this move back and forth, with the

Adding a Moving Platform in 3D Game Kit

In the 3D Game Kit, Game Commands send a signal to other objects in Unity telling them to perform an action.

We’ll be opening a Door using a Pressure Pad. Let’s add a Door to the scene:

The Gizmos on this object can be overwhelming. They can be adjusted to reveal only the Transform tools for the object or easy placement:

 selected in the Hierarchy, Navigate to the Inspector.

Only the Transform tool for the object will now be visible.

 there should be a white arrowed line showing a connection from 

The Pressure Pad will illuminate, descend and make the door open when Ellen steps on it.

Opening a Door with a Command

We have 3 premade enemies in the 3D Game Kit. They can be found in 

The enemies are Chomper, Spitter and Grenadier. Chomper is a close range melee enemy, Spitter is a long range projectile enemy and Grenadier is a boss type enemy with specific attack patterns, a mix of projectile, melee and a shield burst defense.

Let’s place a Chomper in the scene for Ellen to fight:

A large dark blue semi-circle will appear in front of Chomper, this is his 

 When Ellen walks into this area, he will chase and attack her.

Let’s reduce the area in which he can see, with 

Let’s also make Chomper only be able to see from the front:

Now Chomper can only see what is in front of him and at a much closer distance.

Chomper will detect Ellen, but will only run on the spot. We need to tell Chomper where he can move on the ground, we do this by adding a

A light blue surface will appear on top of the ground moving platform. This tells any enemy you place in the scene where they can walk.

Chomper will now run after you and attack!

Use Left Mouse Click to attack with your Staff!

Chomper will die after one hit. To increase this:

 to take before he dies. Ellen’s Staff deals 1 Hit Point

We can inflict damage on objects that has a 

We can Demonstrate how this works using a box and the Chomper

Place it high up so you have time to view it in testing

Note: Don’t get too close to Chomper or he’ll chase after Ellen. You can always reduce his Detection Radius to 0 if you wish.

We need the box to be causing damage when it hits Chomper.

Scroll to the bottom of the Inspector and Click 

Note that the Damage amount must be equal to the

The box will land on Chomper, it will lose its health, turn into its ragdoll state and the box will bounce away. We have successfully caused enough damage to kill the Chomper, but this effect doesn’t look great. We can make the box break when it hits Chomper. It already has a Contact Damager, so let’s adapt it to affect the box.

Damaging with Objects in 3D Game Kit

In the Game Kit we provide all the environment objects we used to build the example game.

They are split into folders of different types of assets. Go through the folders and start building out your scene.

Note: You will need to rebake the NavMesh for your enemies to know that the new surfaces you add are walkable or that they need to avoid objects (like big plants).

To further spruce up your scene, we have created a Rock Painter and a Vegetation Painter. These tools allow you to place vegetation and rocks with varying sizes and rotations while keeping them aligned with the surface you are painting on.

Click on the down arrow to expand its children

Left click to place some grass/lilly pads where you want them.

You can change the type of object being placed to do this:

In the Instance Painter component there are pictures of each prefab in the painter.

Click on the white highlighted box to select that 

Controls for the painter can be found at the top of the 

 Component, some controls to get your started:

Any object you paint on will be stored as a Child of the Parent. For example:

Every object of that type from the paint will be stored here as a child. You can also click on these to individually edit and place them.

Click on the arrow to expand its Children

Hover your mouse over the desired area to place rocks and Click to place.

Decorating in 3D Game Kit

We have a teleporting system in the Game Kit. You can teleport Ellen to other Levels or to different places within your scene.

Let’s create a Teleporter within a scene:

As the name suggests this Gateway is huge:

 to position it and scale it to Ellen's size

Hit Enter on the Keyboard or click on the 

When walking through the teleporter, Ellen will teleport to the location where she initially spawns and blue particles will surround her.

Teleporting the Player in 3D Game Kit

Most objects within the Kit play with the Events system seen in the Pressure Pad setup.

 to see how other objects are set up using the command system in Level 1 and Level 2.
