A-Frame无法显示纹理：请求协助排查问题

Hey there! I’m sorry you’re stuck with that texture not showing up—let’s walk through some common checks to track down the issue.

First, here’s your project info for reference:

• Code editor link: entertaining-garden on Glitch
• Live preview link: entertaining-garden Preview

Since I can’t dive directly into your code right now, here are the most likely culprits to investigate:

• Double-check the texture file path: Make sure the path to your image in line 20 is correct. Typos, wrong folder names (like referencing /assets when the file is in the root), or missing file extensions are super common. Also, confirm the image file actually exists in your Glitch project’s assets folder.
• Wait for the texture to load before rendering: If you’re using WebGL, Canvas, or even plain HTML/CSS, textures won’t render if the image hasn’t finished loading. Did you add an onload handler to make sure the image is ready before trying to use it?
• Verify texture configuration (if using WebGL): If this is a WebGL project, ensure you’ve set up the texture correctly. For example, have you bound the texture to the right context, set proper filtering (gl.TEXTURE_MIN_FILTER, gl.TEXTURE_MAG_FILTER), and handled wrap modes (gl.TEXTURE_WRAP_S, gl.TEXTURE_WRAP_T)? Missing these can make textures appear invisible.
• Check the browser console: Hit F12 to open Developer Tools, then go to the Console tab. Look for 404 errors (meaning the image can’t be found) or JavaScript exceptions—these will often point directly to the problem.

If you can share the code snippet around line 20 (and any related code like texture loading), I can give you a more targeted fix!
