Dora SSR is a game engine for rapid development of 2D games on various devices. It has a built-in easy-to-use development tool chain that supports direct game development on mobile phones, open source handhelds and other devices.
We are delighted to announce that the Dora SSR project has officially become a donation and incubation preparatory project under the Open Atom Foundation. This new stage of development signifies our steadfast commitment to building a more open and collaborative gaming development environment.
The Open Atom Foundation is a non-profit organization dedicated to supporting and promoting the development of open-source technologies. Within this foundation's community, Dora SSR will utilize broader resources and community support to propel the project's development and innovation. For more information, please visit the foundation's official website.

Engine project development
For the installation and configuration of Dora SSR project development, see Official Documents for details.
- Step One: Create a new project
- In the browser, open the right-click menu of the game resource tree on the left side of the Dora Dora editor.
- Click on the menu item
New
and choose to create a new folder.
- Step Two: Write game code
- Create a new game entry code file of Lua (YueScript, Teal, TypeScript or TSX) under the project folder, named
init
. - Write Hello World code:
- Create a new game entry code file of Lua (YueScript, Teal, TypeScript or TSX) under the project folder, named
- Lua
local _ENV = Dora
local sprite = Sprite("Image/logo.png")
sprite:schedule(once(function()
for i = 3, 1, -1 do
print(i)
sleep(1)
end
print("Hello World")
sprite:perform(Sequence(
Scale(0.1, 1, 0.5),
Scale(0.5, 0.5, 1, Ease.OutBack)
))
end))
- Teal
local sleep <const> = require("sleep")
local Ease <const> = require("Ease")
local Scale <const> = require("Scale")
local Sequence <const> = require("Sequence")
local once <const> = require("once")
local Sprite <const> = require("Sprite")
local sprite = Sprite("Image/logo.png")
if not sprite is nil then
sprite:schedule(once(function()
for i = 3, 1, -1 do
print(i)
sleep(1)
end
print("Hello World")
sprite:perform(Sequence(
Scale(0.1, 1, 0.5),
Scale(0.5, 0.5, 1, Ease.OutBack)
))
end))
end

YueScript
The story of YueScript, a niche language supported by Dora SSR, can be found here.
_ENV = Dora
with Sprite "Image/logo.png"
\schedule once ->
for i = 3, 1, -1
print i
sleep 1
print "Hello World!"
\perform Sequence(
Scale 0.1, 1, 0.5
Scale 0.5, 0.5, 1, Ease. OutBack
)
- TypeScript
import {Sprite, Ease, Scale, Sequence, once, sleep} from 'Dora';
const sprite = Sprite("Image/logo.png");
if (sprite) {
sprite.schedule(once(() => {
for (let i of $range(3, 1, -1)) {
print(i);
sleep(1);
}
print("Hello World");
sprite.perform(Sequence(
Scale(0.1, 1, 0.5),
Scale(0.5, 0.5, 1, Ease.OutBack)
))
}));
}

TSX
A much easier approach for building a game scene in Dora SSR. Take the tutorials here.
import {React, toNode, useRef} from 'DoraX';
import {ActionDef, Ease, Sprite, once, sleep} from 'Dora';
const actionRef = useRef<ActionDef.Type>();
const spriteRef = useRef<Sprite.Type>();
const onUpdate = once(() => {
for (let i of $range(3, 1, -1)) {
print(i);
sleep(1);
}
print("Hello World");
if (actionRef.current && spriteRef.current) {
spriteRef.current.perform(actionRef.current);
}
});
toNode(
<sprite
ref={spriteRef}
file='Image/logo.png'
onUpdate={onUpdate}
>
<action ref={actionRef}>
<sequence>
<scale time={0.1} start={1} stop={0.5}/>
<scale time={0.5} start={0.5} stop={1} easing={Ease.OutBack}/>
</sequence>
</action>
</sprite>
);

Rust
You can write code in Rust, build it into WASM file named
init.wasm
, upload it to engine to run. View details here.
use dora_ssr::*;
fn main () {
let mut sprite = match Sprite::with_file("Image/logo.png") {
Some(sprite) => sprite,
None => return,
};
let mut sprite_clone = sprite.clone();
sprite.schedule(once(move |mut co| async move {
for i in (1..=3).rev() {
p!("{}", i);
sleep!(co, 1.0);
}
p!("Hello World");
sprite_clone.perform_def(ActionDef::sequence(&vec![
ActionDef::scale(0.1, 1.0, 0.5, EaseType::Linear),
ActionDef::scale(0.5, 0.5, 1.0, EaseType::OutBack),
]));
}));
}
