Project 1B: Barrel Bouncer (Interactions)
Part 4: Throwing Bouncy Balls
In this section, you will be implementing functionality where you throw a bouncy ball when you left-click on your mouse in order to try to destroy barrels.
Creating the Ball Prefab
To complete the setup for this section, follow these steps:
- Create a new sphere by going to
GameObject->3D Object->Sphere. - Make your own material with a cool color or image texture and apply it onto your sphere.
- Add a Rigidbody to the sphere in order to make it a physical object that is affected by physics and gravity.
- Apply a physic material to make the ball bounce appropriately.
- Scale your ball so that it is appropriately the size of a tennis ball.
- Make this ball into a prefab and remove any instances of the ball from your scene.
Writing the Scripts
In your player controller, you should define a public reference to the ball prefab and implement the following functionality:
- When the left button of your mouse is clicked, the player should throw a new ball in the direction they are facing.
- The ball should be launched using Rigidbody functions and should move in a projectile fashion.
You should also implement the following functionality, but it does not necessarily have to be in the player controller script:
- If a ball collides with a barrel object the barrel should be destroyed.
- Regardless of if anything is hit, the ball should destroy itself after 5 seconds.
Bonus Tasks (Optional)
- Instead of destroying the barrel immediately upon impact with a ball, add a particle effect to it for 3 seconds before destroying it. Check out this package for some cool effects.
- Add some enemy non-player characters (NPC), like zombies, pirates, or dragons, into your scene that constantly move towards the player. They should obey the laws of physics and should also be destroyed if a ball hits it. Additionally, you should use Unity’s navigation system to set the NavMesh and obstacles so that the NPC agents can use pathfinding algorithms and AI to appropriately move around.
