UEBlueprint

A stand alone editor implementation of the UE's Blueprint visual language. (WIP)

Features:

• Intercommunicates with UE (can copy nodes both ways).
• Can be used as a WEB library to visualize, interact and modify Blueprint graphs.
• Can be used inside VS Code to operate directly on files from a UE project (in the future).
• Graph shown is pixel-similar to how it appears in UE.
• Graph behaves the same way as it does in UE (with the default settings).
• All the information shown in he graph is just the one embedded in the serialized text (in VS Code it should be able to access assets also).
• Modern object oriented, clean, JavaScript codebase.

Demo:

Try it!

Getting started:

Run locally

1. Open a terminal in the main folder.
2. Run the following commands.

npm install
npm run build
npx http-server

3. Open the link you see in the last message printed.

Use in a web page

You can check index.html for a working example, the main steps are the following:

1. Include dist/css/ueb-style.css stylesheet in your page.
2. Define eventual CSS variables.

<style>
    ueb-blueprint {
        --ueb-height: 500px;
    }
</style>

3. Import the class Blueprint in JavaScript (this library uses modules).

<script type="module">
    import { Blueprint } from "./dist/ueblueprint.js"
</script>

4. Define your blueprint the by just writing the code inside a ueb-blueprint, inside a template element.

<ueb-blueprint>
    <template>
        ...                   
    </template>
</ueb-blueprint>
