Unity Tutorial 02

Source here.

Today I watched two video tutorials on Unity 02 (Episode 4 & 5). The aim of these tutorials is to observe and learn how I can apply useful techniques to my own game, created via Unity.

What I learned:

 Episode 4:
- You can put in sound effects for when the player interacts with another object (e.g a coin / gem etc).
- 'Play on awake' option means you can have a noise play as soon as you open the game.
- Looping allows audio to play on repeat.
- Public AudioSource allows you to implement the audio in C sharp coding.
- OnTriggerEnter is when the player comes in contact, or hits the object.
- CollectSound.Play allows the noise to play.
- TheGem.Set Active (false) makes the gem (or your created object) disappear.
- Box Collider creates a box around your selected object (you can increase or decrease size), but mesh collider morphs into the shape of the object. This is used when the player crosses the line of the box or mesh collider then the sound effect will go off.
- Adding // in your code turns the text into a comment.
- When you put 'this' into your coding, it basically means whatever object the script is attached to.
- Errors appear in the console area.
- You can import water through your Unity assets.
- You can increase and decrease water level.
- Holding ctrl for snap settings - which would already be written out manually.
- Go into directional light to create shadows ( shadow type - hard / soft).

Episode 5:
- Canvas represents the entire screen.
- The canvas overlays everything we create in our scene (creates an object in front of player, by default in the centre of the screen)
- Whilst on canvas, if you select escape and go on inspector panel and click the colourful box, you can turn the object off.
- You can anchor position of the canvas anywhere on screen.
- Ray cast determines how far an object is from the object it's looking at.
- Static variable means this variable can be referred from different scripts.

Introduction to a CDM student.

Image
My name is Marixa and I am a second year CDM student in ITB. This blog post will tell you a bit about myself and what I hope to achieve in this course. What were my biggest achievements last year? Last year I learned a lot in my course. My favorite module was Web Development, which I would definitely consider as one of my biggest achievements last year! When I started this course I had no idea how to create a website, by the end of the year I had created multiple websites and even learned how to design my finished product! Where did I go over the break? Over the break, I went to many places including Kerry and France, although my most memorable holiday this summer was my visit to Amsterdam. I went over the end of June for the festival "Awakenings". A group of DJ's such as Patrick Topping, Carl Cox, and Bicep were playing at the festival. This is a picture of the festival taken 5 years ago by Geoffrey de Kleijn.  What are my hobbies now? What hobbies would

Original Game Brainstorm.

Image
If I was to make a game, I would like it to be simple yet effective and addictive, thus why I came up with the following ideas: 1. As my first idea I thought of something very simple and easy, a game where the aim of the game is to stack objects (e.g different animated animals) on one another, until the user misses the stack or the stack topples over. The objects will keep alternating from left to right, and when the user thinks that it aligns perfectly with the stack underneath they can release the object to fall onto the stack below. It's a very basic idea, but I think it makes it all the more addictive, as the objective is simple and achievable by almost everyone. In terms of levels, I think it would be cool to make different levels that are optional, but only unlocked after receiving a certain amount of points on the first level. These other levels could include like different shapes or a time mode, to see how many can be stacked in a certain amount of time. Another mode coul

Tech Task - How to Secure your Smartphone!

Image
I think that with our growing social society, our smartphones have become a big part of our every day technology and lives. I created this post because I think rather than teaching someone how to make a meme or create bookmarks, it will be way more beneficial to teach you how to keep your phone secured from real-life everyday threats, such as hackers. Source here . Ways to secure your smartphone: 1. Use a strong password. It's known that the majority of smartphones nowadays have a passcode to access the phone. Use a number/ letter sequence that's unpredictable, for instance don't use your date of birth. 2. Turn off lockscreen notifications. By switching this off, strangers won't be able to read your notifications, over your shoulder, in the case of a robbery, and someone else gets their hands on your phone. 3. Discard automatic Wifi connections to known networks. There's a chance that a cybercriminal will establish his own fak
