Unity中Sprite的Pixel Per Unit设置位置咨询（新手求助）

Hey there! No worries at all—we’ve all fumbled through Unity’s panels as newbies, so your question is totally valid. Let’s break down exactly where to find that Pixel Per Unit setting you’re looking for:

• First, the key mistake many new Unity users make: you don’t adjust this on the Sprite object in your scene. Instead, you need to modify the original Texture file in your Project window.
• Here’s the step-by-step process:
  1. Navigate to your Project window and locate the Texture file that your Sprite uses (not the instance in the Scene Hierarchy).
  2. Select the Texture—your Inspector panel will now show the Texture Import Settings (this is different from the settings for a Sprite object in the scene).
  3. Make sure the Texture Type is set to Sprite (2D and UI) (if it’s set to something else like Texture2D, you won’t see Sprite-specific options). You can change this using the dropdown at the top of the Inspector.
  4. Once the Texture Type is correct, scroll down in the Inspector—you’ll see the Pixel Per Unit field under the Sprite settings section (right below options like Sprite Mode and Pivot). Just input your desired value here, and click Apply at the bottom of the Inspector to save the changes.

A few extra notes to clear up confusion:

• The Canvas Scaler’s Reference Pixel Per Unit is indeed separate—you’re right to ignore that for this task, since that affects UI scaling rather than individual Sprite assets.
• Debug mode in the Inspector won’t help here, as this setting lives in the import settings, not the object’s runtime properties.
• You don’t need any extra packages from the Package Manager for this—this is a core Unity feature for 2D Sprite assets.
