Game engine development

For the installation and configuration of Dora SSR project development, see Official Documents for details.

Quick Start

• 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:

• Lua

local _ENV = Dora

local sprite = Sprite("Image/logo.png")
sprite: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 Sprite <const> = require("Sprite")

local sprite = Sprite("Image/logo.png")
if not sprite is nil then
  sprite: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"
   \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, sleep} from 'Dora';

const sprite = Sprite("Image/logo.png");
if (sprite) {
  sprite.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, toAction, useRef} from 'DoraX';
import {Ease, Sprite, once, sleep} from 'Dora';

const sprite = useRef<Sprite.Type>();

const onUpdate = once(() => {
  for (let i of $range(3, 1, -1)) {
    print(i);
    sleep(1);
  }
  print("Hello World");
  sprite.current?.perform(toAction(
    <sequence>
      <scale time={0.1} start={1} stop={0.5}/>
      <scale time={0.5} start={0.5} stop={1} easing={Ease.OutBack}/>
    </sequence>
  ));
});

toNode(
  <sprite
    ref={sprite}
    file='Image/logo.png'
    onUpdate={onUpdate}
  />
);

• 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),
    ]));
  }));
}

• Step Three: Run the game

  Click the 🎮 icon in the lower right corner of the editor, then click the menu item Run. Or press the key combination Ctrl + r.

• Step Four: Publish the game

  • Open the right-click menu of the project folder just created through the game resource tree on the left side of the editor and click the Download option.
  • Wait for the browser to pop up a download prompt for the packaged project file.
