Solobot - P3 Minimum Target

Progress in Unity

We have learned a great deal about the Unity Editor during our project. We started our development process by studying the Third Person Tutorial project that is downloadable from the Unity Asset Store for free. This project contains a sample player character model that we have used as a stand in until we are able to develop a more suitable replacement. Our lack of an artist has been somewhat of a hinderance. We started by identifying major scripts that controlled the behavior of the Third Person Demo.

Basic Scripting (Scripts of Interest from Third Person Demo Project)--

  • ThirdPersonController
  • This script is attached to your third person player and controls the player object based on user input.
  • This is where the majority of your players behavior is handled. Since the tutorial was third person and we were interested in creating a side scroller, we used this as a guide, but we stripped out a lot of the behavior and locked the player to the XY plane.
  • This script controls the player object, but does not interact with the Camera at all. We called our new script SideScrollController based on this script.
  • ThirdPersonPlayerAnimation
  • This script controls the player object's current animation based on data from the ThirdPersonController.
  • We created a SideScrollPlayerAnimation script that calls the animations provided with the sample character that are provided with the tutorial project.
  • Camera Scripts
  • There were several camera scripts included in sample project, showing how to do a orbit camera based on mouse input, a smooth follow camera, and a spring follow camera.
  • All of these were suitable for a Third Person game but we needed something different for a side-scroller. We were able to write a simple script using the scripting language.
  • We use public variables accessible within the editor in order to change the camera's distance from the player, as well as the x and y offset. For now our camera's Update() method simply follows the x and y position of the players tranform component.

Basic Demo

At this point we were able to get basic side scroller functionality. Here is a video screen capture showing a demo featuring basic side scroller functionality after we completed the above programming based on the Third Person platformer tutorial included with Unity.

Additional Scripts--

  • ThirdPersonCharacterAttack

  • This script is called ThirdPersonCharacterAttack, but it does not have anything to do with the fact that the game is ThirdPerson, we were able to use this as a guide to creating our our SideScrollCharacterAttack script.

  • This script is set as a component of the player object and works by monitoring input and the Character Controller component within its Update() method calls.

  • It also finds objects with the tag 'Enemy' and sends attack messages to them so that damage can be dealt and the appropriate actions can be taken. Simple enough.

  • This currently only handles a Melee attack, so we are going to have to develop either another script to handle our shooting functionality our add on to our script we created here.

  • ThirdPersonStatus

  • This script once again has nothing to do really with the fact that this sample project is a third person example.

  • This script simply keeps up with the players state, we used it as a guide to create our own script that would keep up with our player's current state in our side scroller game.

Project Team Roles

We have a few various roles, but we have all generally contributed to the project.

  • Cory Gross - Documentation, Website, Source Control, Programmer
  • Dillon Daugherty - Design, Sketches, Programmer
  • Jack Satriano - Story, Programmer
  • Carter Micahels - Story, Characters, Programmer
  • Joshua Kane - Documentation, Story, Programmer
  • William Wallace - Sound, Programmer

As we are lacking anyone with formal skills in 3D modelings or as an artist, most of our progress has been technical, in scripting and functionality, rather than in original content.

Adding Enemies

The sample project we were studying also came with one sample enemy and some scripts that controlled it. It also controlled the animations. From this script we were able to create an EnemyController script which is the basis for the script which will control the AI of our enemies.

Here is a video screen capture showing a demo of how the script interacting with our player script. They work by sending messages back and forth, dealing damage to one another. You can see the hit spheres for each of them in yellow in the video. The enemy there had 3 hit points, we had a 6 hits points originally. Because these variables are able to be changed dynamically in the editor I was able to give myself more hit points while debugging the game.
