<!--
Only submit a pull request if all of the following conditions are met:
* It must work with the latest Godot version of the branch you're submitting to.
* It must follow all of the Godot style guides, including the GDScript
style guide and the C# style guide.
* The demo should not be overcomplicated. Simplicity is usually preferred.
* If you are submitting a new demo, please ensure that it includes a
README file similar to the other demos.
* If you are submitting a copy of a demo translated to C# etc:
* Please ensure that there is a good reason to have this demo translated.
We don't want to have multiple copies of every single project.
* Please ensure that the code mirrors the original closely.
* In the project.godot file and in the README, include "with C#" etc in
the title, and also include a link to the original in the README.

<h1>Godot demo projects</h1>
<p>
This page lists
<a href="https://github.com/godotengine/godot-demo-projects">official Godot demo projects</a>
exported to HTML5 for testing purposes. These projects are deployed automatically
on every commit on the <code>master</code> branch of the repository.
</p>
<p>
The HTML5 exports on this page are provided for demonstration purposes only.
Some of these demos may not function or render correctly on HTML5,
especially on mobile devices.
For best performance, it's recommended to
<a href="https://godotengine.org/download">download</a> a native editor
and run the demo project by importing its files in the project manager.
</p>
<p>
See the
<a href="https://docs.godotengine.org/en/stable/getting_started/workflow/export/exporting_for_web.html">Exporting for the Web</a>
documentation for information on exporting your own projects to HTML5.

These demos are all 2D, but otherwise do not have a common theme.
Languages: Most have GDScript, some have

# Bullet Shower
This demonstrates how to manage large amounts of objects efficiently using
low-level Servers.
See
[Optimization using Servers](https://docs.godotengine.org/en/latest/tutorials/performance/using_servers.html)
in the documentation for more information.
Language: GDScript
Renderer: GLES 2
Check out this demo on the asset library: https://godotengine.org/asset-library/asset/887

# Dodge the Creeps
This is a simple game where your character must move
and avoid the enemies for as long as possible.
This is a finished version of the game featured in the
["Your first 2D game"](https://docs.godotengine.org/en/latest/getting_started/first_2d_game/index.html)
tutorial in the documentation. For more details,
consider following the tutorial in the documentation.
Language: GDScript
Renderer: GLES 3 (particles are not available in GLES 2)
Note: There is a C# version available [here](https://github.com/godotengine/godot-demo-projects/tree/master/mono/dodge_the_creeps).
Note: There is a GDNative C++ version available [here](https://github.com/godotengine/gdnative-demos/tree/master/cpp/dodge_the_creeps).
Check out this demo on the asset library: https://godotengine.org/asset-library/asset/515

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide

# Hierarchical Finite State Machine
This example shows how to apply the State machine programming
pattern in GDscript, including Hierarchical States, and a
pushdown automaton.
Language: GDScript
Renderer: GLES 2
Check out this demo on the asset library: https://godotengine.org/asset-library/asset/516
## Why use a state machine
States are common in games. You can use the pattern to:
1. Separate each behavior and transitions between behaviors,
thus make scripts shorter and easier to manage.
2. Respect the Single Responsibility Principle.
Each State object represents one action.
3. Improve your code's structure. Look at the scene tree and
FileSystem tab: without looking at the code, you'll know
what the Player can or cannot do.
You can read more about States in the excellent
[Game Programming Patterns ebook](https://gameprogrammingpatterns.com/state.html).
