Use extensión libraries "inside a web page" #304

Closed asorc closed 4 months ago

asorc commented 5 months ago

Hello,

I am trying to use the patterns extension libraries using Hydra inside a web site.

I tried first to copy the await... statement as in the online example, and It didn't work. Then I downloaded the files and added all.js and lib-pattern.js on an additional line, as the hydra synth is loaded. And It didn't work. Is there a way to make It work?

Thanks in advance. Cheers.

That's the main.html I am using to run Hydra inside a web page offline.

<!DOCTYPE html>
<html lang="en">
  <head>
    <title>hydra inside a webpage</title>
    <meta charset="utf-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />
    <meta name="viewport" content="width=device-width, initial-scale=1" />

    <!-- import the webpage's stylesheet -->
    <link rel="stylesheet" href="style.css" />

    <!-- import the latest version of hydra synth-->
    <script src="hydra-synth.js"></script>
    <script src="lib-pattern.js"></script>
    <!-- script src="hydra-torus-editor.js"></script-->
  </head>
  <body>
    <textarea id="code" rows="2" cols="50" placeholder="Enter code"></textarea>
    <button onclick="eval(document.getElementById('code').value);"> Run </button>
    <button onclick="useCamera()"> camera </button>
    <button onclick="feedback()"> feedback </button>
    <canvas id="myCanvas" width="800" height="650px"></canvas>
    <script>
      // create a new hydra-synth instance
      var hydra = new Hydra({
        canvas: document.getElementById("myCanvas"),
        detectAudio: false
      })
       //osc(10, 0.1, 0.8).rotate(0, 0.1).kaleid().color(-1, 1).out()

      // create functions to use with buttons
      function useCamera() {
        s0.initCam()
        src(s0).color(-1, Math.random()*2, 1).colorama().out()
      }

      function feedback() {
        src(o1)
          .layer(src(o0).mask(shape(4, 0.4, 0)))
          .scrollX([0.005, -0.005])
          .scrollY(0.005)
          .out(o1)

        render(o1)
      }

    </script>
  </body>
</html>

I am using a textarea and a button to run the Code. In this way the "await(loadscript..." does not work as It does It on the hydra web editor.

(I edited your post to fix formatting)

I made a demo here https://editor.p5js.org/micuat/sketches/pI9Ald8Yy

what I added is defer to the script tag only for "lib-pattern.js". I assume it has to be loaded explicitly after the main hydra code is loaded. I'm closing the issue but if you have further questions feel free to reply to / reopen the issue.
