Hello, I'm new to pixijs and spine. I'm trying to render a spine animation version 4.0.17. I first look up spine-runtimes and I don't see spine-pixi for version 4.0.x, so I look for pixi-spine, but there is almost no documentations about this library (pixi-spine examples on github). According to this forum question, pixi-spine works the same as spine-pixi by esoteric software, so I tried to follow esotericsoftware docs, but things didn't go the way I expected. I'm trying to get the below code going to work, but the result is only 1 frame of the spine being displayed when I call the render function. I've attach the skel and atlas file, please help me. I'm using pixijs v6.5.10 and pixi-spine v4.0. When I set the animation, it still run, but I have a strong reason to render it frame by frame. <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <title>Spine Animation</title> <script src="https://cdnjs.cloudflare.com/ajax/libs/pixi.js/6.5.10/browser/pixi.js"></script> <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/pixi-spine.umd.js"></script> <style> body { margin: 0; overflow: hidden; background-color: rgb(76.5, 76.5, 76.5); height: 100vh; width: 100vw; } canvas { width: 100%; height: 100%; display: block; } </style> </head>a <body id="container"> <canvas id="canvas"></canvas> <div style="color: #fff; position: fixed; top: 0; width: 100%; display: flex; justify-content: center;"> <span id="status"></span> <span id="animation"></span> <span>Render: </span><button id="render">Render next frame</button> </div> <script> var spineAnimation; var lastFrameTime; var canvas = document.getElementById("canvas"); var gl = canvas.getContext("webgl") || canvas.getContext("experimental-webgl"); if (!gl) { alert('WebGL is unavailable.'); } var renderButton = document.getElementById('render'); renderButton.addEventListener('click', render); const pixiapp = new PIXI.Application({ width: window.innerWidth, height: window.innerHeight, transparent: true, backgroundAlpha: 0, view: document.getElementById("canvas"), resizeTo: document.getElementById("container") }); document.body.appendChild(pixiapp.view); pixiapp.loader .add("spine", "./spines/Eff_UI_SumeruBirthFloatToyLoading_Spine01.skel") .load((loader, resources) => { try { document.getElementById("status").textContent = "Spine created, loading animation..."; spineAnimation = new PIXI.spine.Spine(resources.spine.spineData); if (spineAnimation) { spineAnimation.scale.set( Math.min( window.innerWidth / spineAnimation.spineData.width, window.innerHeight / spineAnimation.spineData.height ) * 0.8 ); spineAnimation.x = window.innerWidth / 2; spineAnimation.y = pixiapp.screen.height / 2 + spineAnimation.height / 2; pixiapp.stage.addChild(spineAnimation); spineAnimation.skeleton.setToSetupPose(); lastFrameTime = Date.now() / 1000; spineAnimation.state.setAnimation(0, "In", true); window.addEventListener("resize", () => { spineAnimation.scale.set( Math.min( window.innerWidth / spineAnimation.spineData.width, window.innerHeight / spineAnimation.spineData.height ) * 0.8 ); spineAnimation.x = window.innerWidth / 2; spineAnimation.y = pixiapp.screen.height / 2 + spineAnimation.height / 2; }); document.getElementById("status").textContent = "Animation loaded"; } requestAnimationFrame(render); } catch (error) { console.error("Spine creation error: ", error); } }); function render() { var state = spineAnimation.state; var skeleton = spineAnimation.skeleton; var animationDuration = spineAnimation.spineData.animations.find(animation => animation.name === "In").duration; var now = Date.now() / 1000; var delta = now - lastFrameTime; lastFrameTime = now; document.getElementById("animation").textContent = `now: ${now} delta: ${delta} anim: ${animationDuration}`; state.update(delta); state.apply(skeleton); // requestAnimationFrame(render); } </script> </body> </html> Eff_UI_SumeruBirthFloatToyLoading_Spine01.skel Eff_UI_SumeruBirthFloatToyLoading_Spine01.atlas https://streamable.com/wdnbzt Above is a video of how it behave.
