Unity 2d Javascript Game Tutorial

| | | | | | |

Sometimes the best way to get into the game design is to jump right. In seeing the results of your work on the move on the screen is the exciting and creative enthusiasm is the best fuel for the design of the game.

This tutorial will show you how to start building a game with unity, starting with an idea. You will learn a bit more about how to make 2D Unity games. In addition, you will learn a good starting method for creating Unity 2D games from scratch.

It’s important to note that this tutorial will not make you a full-fledged unit developer or teach you how to code. However, it will guide you to get something working on the screen quickly.

Unity is one of the most popular free game engines available. It also has an excellent 2D engine, so no 3D models are needed. One other interesting feature of the unit is that it requires no extensive knowledge of programming.

Game development with Unity is useful for creating things that have already been built. For example, Sepulchral Knight, a platform fantasy metroidvania , and Ori and the Blind Forest have been created on the unit. In short, the unit is perfect for designing small indie games.

Here is a step by step tutorial on how to make a 2D game in unity for beginners.

phase 1: Idea

The first step is pretty straightforward. you can easily do it in your head.

Before you start, decide what type of game you are doing. To understand, here are some game design questions you should ask yourself:

  • Is it a platform game, a top down game or maybe isometric ?
  • What will be the theme and the basic story is
  • What will it be like?
  • What engine will you be using ?
  • More importantly , how does your game stand out? What’s new mechanic or idea - does - he introduced, or will do?

While you don’t need solid or specific answers to most of these questions, you do need a general idea of ‚Äã‚Äãwhat you will be doing before you start. You can develop this idea and create a basic prototype later. Some people like to do it on paper, while others can just think about it.

to start, we are going to make a platform game . For this example, the special rule is Platforming that a player must control two characters at the same time to solve the puzzles and the characters must meet to complete the level.

Once you have some ideas on what to do, you have a guide to get started. Now you can move on to prototyping.

Step 1.5: Get your tools

To design a game in Unity, you will need Unity. You can download the personal version . Please note that the personal version is only necessary if you do the have not earned more than $ 100,000 in funding or income for your game. Once you’ve done that, we hope that you do don’t need this tutorial.

Download first ’Unity Hub’. Then open the hub, go to ’Install’ and click ’Add’. This tutorial will use Unity version 2019.2.14f1. You can install as many packages as you want or have space to , depending on the goals you want the game to run on. This tutorial will launch the game on Windows, so make sure the " Windows version support" box is checked.

You can also create graphics for your game. Since the pixel art unit involves , I highly recommend use GraphicsGale. GraphicsGale is free, easy to use, and feature rich. However, feel free to use any editor you feel comfortable with, be it Photoshop, Blender, or Windows Paint. As you can create images with rear - transparent plans, you should be fine.

step 2:. Configure your project

While installing Unity, you may take some time to prepare some of your resources for some graphics. replacement, called placeholders, in m I hear you can see what you’re doing. Ci vorrà un po ’di tempo per disegnare tutte le animazioni del tuo personaggio, i nemici e ambiente, quindi puoi iniziare con una grafica semplice.

Utilizziamo GraphicsGale per questo tutorial, ma puoi usare qualsiasi editor tu Like, how. Start by creating a replacement for your walls in the game. (Remember , you can always do this later.) The walls should be 100 pixels by 100 pixels in size

Here is an example:.

Once Unity has finished downloading, you can open Unity Hub and start a new project. Project name you want, but you do you select 2D for project setup

Make - to use the 2D model.

Welcome to Unità! You should now be looking at the Unity editor. To navigate 2D space in the editor window , use the middle mouse button to move and the scroll wheel to zoom. The camera in the center of the space represents what the player will see.


Unity has one feature amazing called Unity Asset Store. The store is filled with assets with predefined game pieces such as models, textures, utilities or artificial intelligence programs. These are available for sale and some are even offered for free. On account of this, it is easy to make a game without creating too much from you - even assets. You can simply take the pre-coded game mechanics and attach them to your graphics.

To access these free basic programming resources , simply go to the "Resources Store" tab at the top of the viewing window. From there, go to Top Free Resources "and download the" Standard Resources (for Unit 2017.3) package. You may need to log in or create an account.

Once the package is downloaded, press "Import" (replaces the download button after the assets have been downloaded) to import the package into the current project the unit. You will be presented with a long list of checkboxes. Thatwhat packaging you add is up to you. For this tutorial, you just need the ’2D’ folder and the ’CrossPlatformInput’ in the ’standard resources’ folder.

You also need tools to create 2D games in unity which will help you a lot. Go to this link and download Git as a zip. Then unzip and drag inside the folder in your resource browser. You may need to restart the unit again. late to make it work properly.

Now you should have everything you need to get started. It’s time to dig in and start building it works

Step 3:. Create the map

To start creating the map, first go back to the "Scene" tab. In the Resource Browser at the bottom of the screen, right click and click Create> Folder. Name the new resource folder

You will also add your own art of ’ space reserved for the asset browser. It simply drag and drop the full Windows folder in the resource browser.

Next, create a palette that will serve as blocks your character will have to stumble upon. Go to Window> 2D> Tile Palette to open the Tile Palette window. Click on " create a new palette " to create a new palette of tiles. Call it "solid" but keep all the defaults and save it in the folder called ’Tiles’

How can I make a time delay in Python?

5 answers

I would like to know how to put a time delay in a Python script.


Answer #1

import time
time.sleep(5)   # Delays for 5 seconds. You can also use a float value.

Here is another example where something is run approximately once a minute:

import time
while True:
    print("This prints once a minute.")
    time.sleep(60) # Delay for 1 minute (60 seconds).


Answer #2

You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.

from time import sleep
sleep(0.1) # Time in seconds

JSON datetime between Python and JavaScript

4 answers

kevin By kevin

I want to send a datetime.datetime object in serialized form from Python using JSON and de-serialize in JavaScript using JSON. What is the best way to do this?


Answer #1

You can add the "default" parameter to json.dumps to handle this:

date_handler = lambda obj: (
    if isinstance(obj, (datetime.datetime, datetime.date))
    else None
json.dumps(datetime.datetime.now(), default=date_handler)

Which is ISO 8601 format.

A more comprehensive default handler function:

def handler(obj):
    if hasattr(obj, "isoformat"):
        return obj.isoformat()
    elif isinstance(obj, ...):
        return ...
        raise TypeError, "Object of type %s with value of %s is not JSON serializable" % (type(obj), repr(obj))

Update: Added output of type as well as value.
Update: Also handle date

What blocks Ruby, Python to get Javascript V8 speed?

4 answers

Are there any Ruby / Python features that are blocking implementation of optimizations (e.g. inline caching) V8 engine has?

Python is co-developed by Google guys so it shouldn"t be blocked by software patents.

Or this is rather matter of resources put into the V8 project by Google.


Answer #1

What blocks Ruby, Python to get Javascript V8 speed?


Well, okay: money. (And time, people, resources, but if you have money, you can buy those.)

V8 has a team of brilliant, highly-specialized, highly-experienced (and thus highly-paid) engineers working on it, that have decades of experience (I"m talking individually – collectively it"s more like centuries) in creating high-performance execution engines for dynamic OO languages. They are basically the same people who also created the Sun HotSpot JVM (among many others).

Lars Bak, the lead developer, has been literally working on VMs for 25 years (and all of those VMs have lead up to V8), which is basically his entire (professional) life. Some of the people writing Ruby VMs aren"t even 25 years old.

Are there any Ruby / Python features that are blocking implementation of optimizations (e.g. inline caching) V8 engine has?

Given that at least IronRuby, JRuby, MagLev, MacRuby and Rubinius have either monomorphic (IronRuby) or polymorphic inline caching, the answer is obviously no.

Modern Ruby implementations already do a great deal of optimizations. For example, for certain operations, Rubinius"s Hash class is faster than YARV"s. Now, this doesn"t sound terribly exciting until you realize that Rubinius"s Hash class is implemented in 100% pure Ruby, while YARV"s is implemented in 100% hand-optimized C.

So, at least in some cases, Rubinius can generate better code than GCC!

Or this is rather matter of resources put into the V8 project by Google.

Yes. Not just Google. The lineage of V8"s source code is 25 years old now. The people who are working on V8 also created the Self VM (to this day one of the fastest dynamic OO language execution engines ever created), the Animorphic Smalltalk VM (to this day one of the fastest Smalltalk execution engines ever created), the HotSpot JVM (the fastest JVM ever created, probably the fastest VM period) and OOVM (one of the most efficient Smalltalk VMs ever created).

In fact, Lars Bak, the lead developer of V8, worked on every single one of those, plus a few others.

Django Template Variables and Javascript

4 answers

When I render a page using the Django template renderer, I can pass in a dictionary variable containing various values to manipulate them in the page using {{ myVar }}.

Is there a way to access the same variable in Javascript (perhaps using the DOM, I don"t know how Django makes the variables accessible)? I want to be able to lookup details using an AJAX lookup based on the values contained in the variables passed in.


Answer #1

The {{variable}} is substituted directly into the HTML. Do a view source; it isn"t a "variable" or anything like it. It"s just rendered text.

Having said that, you can put this kind of substitution into your JavaScript.

<script type="text/javascript"> 
   var a = "{{someDjangoVariable}}";

This gives you "dynamic" javascript.
