Why we chose Unity 3 D minimizing dependencies, maximizing flexibility

Using a few powerful and flexible programs Unity 3 D Development, version control and multi-platform targeting Visual Studio Script editing and debugging Maya More rapid asset generation and animation …and they have been checked out to play very nice together

Why we chose Unity 3 D Easy to approach Flexible and powerful Very active development Broad user base

Scripting Introduction Programming the game

Scripting Overview Developing a game is different than traditional programming All pieces of executing code is connected to an object in scene Update functions are where most code execution is initiated Code needs to be efficient/performant to reach 60 FPS

Scripting Good Habits Break out code into minimally containable form Objects can have many scripts attached to them Making the scripts into small independent entities makes for easy reuse of code Easier to maintain smaller pieces of code Use provided functions as much as possible Phys. X functions in unity run orders of magnitude Quaternions for rotations are easy to use Functions are documented at docs. unity 3 d. com

General Script Structure Awake() Start() Update() Fixed. Update() Runs when the script is initialized Runs before the first Update Runs every frame Runs every physics frame Useful for initialization code Useful for getting the script ready for the first update Useful for updating visual information before a frame is rendered Useful for updating location, collision, physics forces etc.

Rigidbody Collider Camera Audio Listener Audio Source • Defines a body that will respond to physics forces as a rigid object • Defines the shape of the physics collider this object will use • This is simply the object that is set to create a view of the scene during gameplay • This listens to audio sources in the scene, taking into account distance form the source • This projects a specified audio file in the scene from a predetermined location Some Used Object Components

Tank Demo This demo is found on the Unity 3 D website Under learning These demos are great ways to get your feet wet I will be using this tank demo as: An example of coding techniques A base to build upon A way to introduce some slightly more advanced Unity development tools

Tanks Destructible Environment Design Goals Shooting a building a few times causes it to collapse The collapse should remove the building The collapse ‘animation’ should look ‘good’ Able to select if buildings respawn after each round or game

Adding and modifying scripts Add a Building. Health script Keep track of health Control death animation Modify Shell. Explosion script Apply damage to buildings Modify Game. Manager Reset buildings each round

Extending the Editor Custom Editor Any script inheriting from Mono. Behaviour can have a customized editor in the inspector Property Drawer Any class that is Serializable can have a customized drawer in the inspector Both are useful for: Grouping up sets of variables Displaying custom information/warnings Generating simple visuals
