Blender 教學：用 Driver 把車輪旋轉與車身移動連結起來，令 4 個車輪自動跟著車身轉動。

## Overview

![](https://aaronchan.com/wp-content/uploads/2026/09/step_1-1.png)

**流程：**[1] 建立 4 個車輪 → [2] 建立車身（cube）→ [3] 在 1 個車輪加入 driver → [4] 把 driver 複製到其餘 3 個車輪 → [5] 把車輪與車身建立父子關係

**備註：** 相當於 After Effects 的 expression。

## Step 1：加入圓柱體

**做法：** Shift-A → Mesh → Cylinder

---

## Step 2：縮放並旋轉圓柱體成車輪

**做法：** R-Y-90（旋轉 90 度）→ R-X-0.2（變薄）→ S-0.5（縮小）

---

## Step 3：套用變更

**做法：** Ctrl-A → Scale、Rotation

## Step 4：套用棋盤格紋理

**做法：** Material properties → New → Base Color → 點黃色圓點 → checker texture → 把 shader 切換到 preview

## Step 5：複製並擺放車輪

**做法：** keypad-7（頂視圖）→ 選取車輪 → Shift-D（複製）→ G-Y / G-X（移動）

## Step 7：加入 driver

**做法：** 選取 1 個車輪 → object properties 面板 → 右鍵 Rotation-X → Add driver → 欄位變成紫色

## Step 8：編輯 driver，連結車身 Y 軸位置

**做法：** 右鍵紫色欄位 → Edit driver → 點 Object 欄位 → 下拉選 Cube → Type 選 Y Location

## Step 9：修正車輪旋轉方向

**做法：** 選取車輪 → 右鍵紫色欄位 → Edit driver → Driver Property → Expression → var * -1

## Step 10：把 driver 套用到 4 個車輪

**做法：** 右鍵紫色欄位 → copy driver → 逐一選取其餘車輪 → 右鍵 Rotation-X 欄位 → paste driver

## Step 11：令車輪與車身一起移動

**做法：** 選取 4 個車輪 → 選取 cube → Ctrl-P（Parent）
