+01.
+ Getting Started with Godot Engine
+\end_layout
+
+\begin_layout Section*
+Introduction:
+\end_layout
+
+\begin_layout Standard
+Godot Engine is designed to be useful.
+ This may sound rather vague and is difficult to explain without repeating
+ the same claims that every other engine does, but, as we progress through
+ this (and the next) tutorials, hopefully it will be made clear what 
+\begin_inset Quotes eld
+\end_inset
+
+useful
+\begin_inset Quotes erd
+\end_inset
+
+ means.
+\end_layout
+
+\begin_layout Standard
+Godot Engine has many components, both high and low level, and is usually
+ more abstract and complex than most other engines.
+ This is, however, to the advantage of the user as complexity is presented
+ in a way that it only needs to be discovered when more power needs to be
+ untapped.
+ This helps to provide an easy learning curve.
+\end_layout
+
+\begin_layout Standard
+Design wise, the whole API and set of components were created with a clear
+ goal in mind, which is to allow for smooth integration of design ideas,
+ code and assets.
+ This is achieved by defining the following rules:
+\end_layout
+
+\begin_layout Itemize
+Implementing a game feature should never be too many steps away from an
+ existing component.
+\end_layout
+
+\begin_layout Itemize
+More complex features should be leveraged by combining or extending existing
+ components.
+\end_layout
+
+\begin_layout Itemize
+If the above fails, creating custom components should be extremely simple.
+\end_layout
+
+\begin_layout Standard
+Ultimately, Godot Engine provides an editor and tools that allows everyone
+ to work with it:
+\end_layout
+
+\begin_layout Itemize
+Programmers can script and extend any component of the project.
+\end_layout
+
+\begin_layout Itemize
+Designers can tweak and animate any parameter from a friendly user interface.
+\end_layout
+
+\begin_layout Itemize
+Artists can import their art and models and tweak the look of everything
+ in realtime.
+\end_layout
+
+\begin_layout Section*
+Editor:
+\end_layout
+
+\begin_layout Standard
+As mentioned before, Godot Engine is very abstract so projects consist of
+ just a 
+\emph on
+path
+\emph default
+ (ie: C:
+\backslash
+games
+\backslash
+mygame5).
+ Projects don't have to be specifically created, and many can be placed
+ inside the same path (useful for not wasting folders on tests and experiments).
+ 
+\end_layout
+
+\begin_layout Standard
+In any case, to ease the management of projects, a graphical util exists.
+\end_layout
+
+\begin_layout Subsection*
+Running From The Project Manager
+\end_layout
+
+\begin_layout Standard
+Godot Engine includes a built-in project manager.
+ This is installed by default on Windows and OSX and it allows for the creation
+ and removal projects that will be remembered at the next startup:
+\end_layout
+
+\begin_layout Standard
+\align center
+\begin_inset Graphics
+	filename pm.png
+
+\end_inset
+
+
+\end_layout
+
+\begin_layout Standard
+To create a new project, the [Create] button must be pressed and a dialog
+ will appear, prompting for a path and project name.
+ Afterwards, the [Open] button will close the project manager and open the
+ desired project.
+\end_layout
+
+\begin_layout Subsection*
+Running From the Command Line
+\end_layout
+
+\begin_layout Standard
+To create and manage projects, it is perfectly possible to use the command
+ line.
+ Many users prefer this way of working with project data.
+\end_layout
+
+\begin_layout Standard
+\align center
+\begin_inset Graphics
+	filename pmc.png
+
+\end_inset
+
+
+\end_layout
+
+\begin_layout Standard
+For ease of use, it is recommended that the 
+\begin_inset Quotes eld
+\end_inset
+
+godot
+\begin_inset Quotes erd
+\end_inset
+
+ binary exists in the path, so any project can be opened easily aywhere
+ just by changing location to the projec and executing the editor.
+\end_layout
+
+\begin_layout Subsection*
+Godot Editor
+\end_layout
+
+\begin_layout Standard
+Godot Editor should have been opened by now, if not please check the previous
+ steps again.
+\end_layout
+
+\begin_layout Standard
+Godot has a powerful buit-in editor.
+ It uses the graphics toolkint within itself to display the UI, so it runs
+ identical on any platform (even consoles or phones!).

+
+\end_layout
+
+\begin_layout Standard
+In the above screenshots, a few regions are labelled to be explained as
+ follows:
+\end_layout
+
+\begin_layout Subsubsection*
+Viewport
+\end_layout
+
+\begin_layout Standard
+The 
+\emph on
+Viewport
+\emph default
+ is the main space where the content is displayed.
+ Content includes 3D Nodes or Graphical User Interface (GUI) controls.
+ Other types of data spawn editors of their own when being edited.
+ The default viewport is the 3D viewport, which can be panned, zoomed, etc.
+\end_layout
+
+\begin_layout Subsubsection*
+Scene Tree
+\end_layout
+
+\begin_layout Standard
+The 
+\emph on
+Scene Tree
+\emph default
+ is a small dock that displays the tree of the current scene being edited.
+ A scene is a collection of nodes arranged in a tree-hierarchy (any node
+ can have several owned children-nodes).
+ The meaning of this ownership depends purely on the 
+\emph on
+type
+\emph default
+ of the node, but it will become clear after going through the examples.
+ In a 
+\emph on
+MVC
+\emph default
+ pattern, the scene tree could be considered the 
+\emph on
+View
+\emph default
+.
+\end_layout
+
+\begin_layout Subsubsection*
+Property Editor
+\end_layout
+
+\begin_layout Standard
+The 
+\emph on
+Property Editor
+\emph default
+ is another small dock.
+ Every node contains a finite number of 
+\emph on
+properties
+\emph default
+, which can be edited.
+ Properties can be of several types, such as integers, strings, images,
+ matrices, etc.
+ Usually, changes to properties are reflected in the 
+\emph on
+viewport
+\emph default
+ in real time.
+\end_layout
+
+\begin_layout Section*
+Examples:
+\end_layout
+
+\begin_layout Standard
+From now, a few, simple examples will be presented that will help understand
+ a little better how Godot Engine works.
+

+\begin_layout Standard
+In many cases, nodes and other types of engine objects need to express changes
+ in their state, such as a button being pressed, a scroll being dragged,
+ or a projectile colliding against a tank.
+ Godot Engine utilizes the concept of signals for this.
+ Different types of nodes and objects can emit signals, and any other node
+ or object can connect to them.
