One of the best tips I have ever gotten as a freelance developer is to start your project right away.

The big triple A studios start with a long process of design, concept and prototyping. While this process is effective for large studios, it can bog down independent or single developers.

Often the best first step after getting an idea for a game is to code the ultimate mechanic. The objective of this step is to create a simple game to test if it will work.

This gives you something that you can actually see the real results of. Then create a starting point from which you can develop your project. Engine

In this tutorial, we will go through this process of starting together in a game made for 2D games and in development fast: GameMaker studio 2 by Yoyo Games.

The name GameMaker has been around for a while and many amazing and successful games have been made. made using this game development tool. for example, Undertale, Hyperlight Drifter and Hotline Miami were all made using GameMaker studio.

A Note About Game Engines
While I really like GameMaker Studio 2, there are a myriad of for a fee. After all, the best game engine is the one you feel most comfortable with and which allows you to create what you want to create.

Every engine is different or powerful on the inside ’in your own way, and if you’re still the best engine for you, my advice is to keep trying several before you land on the one you want to use. your favorite engine might be something very different from what we use today, the principles used here are still useful to any novice developer

In this GameMaker Studio 2 tutorial, we will learn how to create a game from an idea , then on the creation of a prototype around this idea .

You will learn some code and some game design as we go.

Note: You should know some coding basics (like what is a variable), as this tutorial doesn’t go too deep on how this code works. However, if you are new to programming you should still be able to keep up.

GameMaker vs Drag Drop Language
GML, or GameMaker Language, is GameMaker’s proprietary programming language. Although proprietary languages ‚Äã‚Äãare generally a bad thing, GML is very close to JavaScript in that it is typed dynamically and at a high level. It is easy to read and type and works very similar to other languages. As a result, it is difficult to switch to another language, such as Lua, after learning GML. Drag and drop
is not a code solution for creating GMS 2 games. It is very easy to use and emulates the code quite well. However, I have found that visual coding languages like Drag and Drop tend to hold back developers who would be better at learning all the code. Dragging and dropping is just more work for less functionality, so we’ll stick to GML for this tutorial

Since we’ve just received the program, we’ll take a look at the interface.

The page you start from is the Workspace. This is where we will be working on the art and code for our project, among other things.

on the right are your resources in the Resource tree. This will contain all the elements of your game, be it an audio file, a sprite or a block of code.

If you click on the Rooms dropdown menu Resource tree, you will see that we have a default start up place for our game. double clicking on it opens the place tab for that part, which is currently just a black background.

Rooms are what they look like: places where you can put your sprites and game elements.

They can be any size and 2 GMS has a camera / view system, our room does not have to be the same size as our screen.

For now, we’ll leave this default set with the piece taking the entire game window.

If you want to see your game (again just a black screen), press F5 to launch the game.

Right now everything looks very empty, so we’ll start creating our game.

Step 2: Creation of our character

The next step we want to take in our GameMaker Studio 2 tutorial is to create a character that the player can control.

2 uses GMS Objects as containers for anything general attached to code. elements have a number of built-in properties that will help us build our game, so it makes sense to create a new element of our character.

Right click the Objects drop-down menu in the active panel and click Create Object.

Now we can see a object panel .

On the left is the space where we can give the object a name and a sprite, along with a few other options.

On the right is the Event Space, which will be where we put everything our code (more on that later).

Rename our new object to obj_player in the name box.

Naming Practices

It is a very good idea to name things in a way that tells you what they are. For example, many people will name their names. obj_somthing or Osomething objects. That way they know if what they are using is an object or something else.

We do this because we will often have to mention the names of things in our code. It can become difficult to remember what is what, so this helps with organization. This is also useful if you want to name two different things with the same name, like obj_player (for the object) and spr_player (for the sprite).

For now, unfortunately, our player object doesn’t look like anything . This is because it doesn’t have a Sprite yet. Let’s create a new Sprite and add it to the player object.

Right click on the Sprite section from the Resource Tree , then click on Create Sprite.

For the box, I’ll name this spr_player . Sprites are the word of game developers for images. Sprites don’t do anything, they’re just images that are sometimes animated that we attach to things that have code, like objects, or that we insert into our scene to look cute.

Our workspace now has two boxes. To navigate in the workspace, use the scroll wheel to scroll or the middle mouse button to move.

At the moment, it’s a bit small. Let’s make it a little bigger. Click the small box with four arrows under Image size and set the width and height to 64 √ó 64 pixels under Image size.

Now that it’s the right size, let’s draw on it. Click on Edit Image next to the size button. This will open the sprite in a new sprite editor tab.

Now let’s draw something simple to represent our character. For the result, we can go back and draw animated sprites that look more like a box.

But to start making our prototype, we just need something that tells us where our player is and how tall he is. Remember that it appears on a black background for now, so don’t make it black .

Removing white space around a saved image in matplotlib

2 answers

I need to take an image and save it after some process. The figure looks fine when I display it, but after saving the figure, I got some white space around the saved image. I have tried the "tight" option for savefig method, did not work either. The code:

  import matplotlib.image as mpimg
  import matplotlib.pyplot as plt

  fig = plt.figure(1)
  img = mpimg.imread(path)
  plt.imshow(img)
  ax=fig.add_subplot(1,1,1)

  extent = ax.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
  plt.savefig("1.png", bbox_inches=extent)

  plt.axis("off") 
  plt.show()

I am trying to draw a basic graph by using NetworkX on a figure and save it. I realized that without a graph it works, but when added a graph I get white space around the saved image;

import matplotlib.image as mpimg
import matplotlib.pyplot as plt
import networkx as nx

G = nx.Graph()
G.add_node(1)
G.add_node(2)
G.add_node(3)
G.add_edge(1,3)
G.add_edge(1,2)
pos = {1:[100,120], 2:[200,300], 3:[50,75]}

fig = plt.figure(1)
img = mpimg.imread("image.jpg")
plt.imshow(img)
ax=fig.add_subplot(1,1,1)

nx.draw(G, pos=pos)

extent = ax.get_window_extent().transformed(fig.dpi_scale_trans.inverted())
plt.savefig("1.png", bbox_inches = extent)

plt.axis("off") 
plt.show()

Answer #1

You can remove the white space padding by setting bbox_inches="tight" in savefig:

plt.savefig("test.png",bbox_inches="tight")

You"ll have to put the argument to bbox_inches as a string, perhaps this is why it didn"t work earlier for you.

Answer #2

I cannot claim I know exactly why or how my “solution” works, but this is what I had to do when I wanted to plot the outline of a couple of aerofoil sections — without white margins — to a PDF file. (Note that I used matplotlib inside an IPython notebook, with the -pylab flag.)

plt.gca().set_axis_off()
plt.subplots_adjust(top = 1, bottom = 0, right = 1, left = 0, 
            hspace = 0, wspace = 0)
plt.margins(0,0)
plt.gca().xaxis.set_major_locator(plt.NullLocator())
plt.gca().yaxis.set_major_locator(plt.NullLocator())
plt.savefig("filename.pdf", bbox_inches = "tight",
    pad_inches = 0)

I have tried to deactivate different parts of this, but this always lead to a white margin somewhere. You may even have modify this to keep fat lines near the limits of the figure from being shaved by the lack of margins.

How to insert newlines on argparse help text?

5 answers

I"m using argparse in Python 2.7 for parsing input options. One of my options is a multiple choice. I want to make a list in its help text, e.g.

from argparse import ArgumentParser

parser = ArgumentParser(description="test")

parser.add_argument("-g", choices=["a", "b", "g", "d", "e"], default="a",
    help="Some option, where
"
         " a = alpha
"
         " b = beta
"
         " g = gamma
"
         " d = delta
"
         " e = epsilon")

parser.parse_args()

However, argparse strips all newlines and consecutive spaces. The result looks like

~/Downloads:52$ python2.7 x.py -h
usage: x.py [-h] [-g {a,b,g,d,e}]

test

optional arguments:
  -h, --help      show this help message and exit
  -g {a,b,g,d,e}  Some option, where a = alpha b = beta g = gamma d = delta e
                  = epsilon

Try using RawTextHelpFormatter:

from argparse import RawTextHelpFormatter
parser = ArgumentParser(description="test", formatter_class=RawTextHelpFormatter)

Is a Python list guaranteed to have its elements stay in the order they are inserted in?

5 answers

If I have the following Python code

>>> x = []
>>> x = x + [1]
>>> x = x + [2]
>>> x = x + [3]
>>> x
[1, 2, 3]

Will x be guaranteed to always be [1,2,3], or are other orderings of the interim elements possible?

Answer #1

Yes, the order of elements in a python list is persistent.

Inserting image into IPython notebook markdown

5 answers

I am starting to depend heavily on the IPython notebook app to develop and document algorithms. It is awesome; but there is something that seems like it should be possible, but I can"t figure out how to do it:

I would like to insert a local image into my (local) IPython notebook markdown to aid in documenting an algorithm. I know enough to add something like <img src="image.png"> to the markdown, but that is about as far as my knowledge goes. I assume I could put the image in the directory represented by 127.0.0.1:8888 (or some subdirectory) to be able to access it, but I can"t figure out where that directory is. (I"m working on a mac.) So, is it possible to do what I"m trying to do without too much trouble?

277

Answer #1

Most of the answers given so far go in the wrong direction, suggesting to load additional libraries and use the code instead of markup. In Ipython/Jupyter Notebooks it is very simple. Make sure the cell is indeed in markup and to display a image use:

![alt text](imagename.png "Title")

Further advantage compared to the other methods proposed is that you can display all common file formats including jpg, png, and gif (animations).
