【Tank】7.0 子弹模型和画布、子弹运动、砖墙打掉
Author: 图恩Category: 编程开发Views: 722Published: 2022-05-16 The issue with the bullet not moving in the game is primarily due to **incomplete or improper triggering of the bullet's movement logic**. Here's a breakdown of the root cause and solution:
---
### 🔍 **Root Cause**
The bullet's movement is handled in the **tank's renderModels()** method, but the tank's movement logic is not properly triggering the bullet's update. Specifically:
- The **tank's movement** is handled in the `move()` method, which updates the tank's position and calls `super.draw()`.
- However, the **bullet's position** is updated in the **tank's renderModels()** method, which is not called when the tank moves.
- This means the bullet's position is **not updated** when the tank moves, leading to it **not moving**.
---
### 🛠 **Solution**
To fix this, ensure that the **bullet's position is updated** when the tank moves. Here's how to do it:
#### 1. **Update the Tank's Movement Logic**
In the `move()` method, after updating the tank's position, call the **bullet's update logic**. This can be done by:
```typescript
// Inside the move() method
this.updateBulletPosition(); // Call this to update the bullet's position
```
#### 2. **Implement Bullet Position Update**
Add a method to the `Tank` class to update the bullet's position:
```typescript
// In Tank.ts
protected updateBulletPosition(): void {
// Logic to update the bullet's position based on the tank's movement
// This could be done in the renderModels() method
}
```
#### 3. **Ensure Bullet's Position is Updated in Render Models**
The bullet's position should be updated in the `renderModels()` method of the tank. This is already handled, but ensure it's properly triggered:
```typescript
// In Tank.ts
public renderModels(): void {
// Update the bullet's position when the tank moves
this.updateBulletPosition();
// Rest of the render logic
}
```
---
### ✅ **Key Fixes**
- **Call `updateBulletPosition()`** in the `move()` method to ensure the bullet's position is updated.
- **Ensure the bullet's position is updated** in the `renderModels()` method of the tank.
- **Verify that the tank's movement logic is properly triggered**, which in turn updates the bullet's position.
---
### 📌 **Summary**
The bullet isn't moving because the tank's movement logic isn't properly triggering the bullet's update. By explicitly calling a method to update the bullet's position in the tank's movement logic, the bullet will move as intended. This ensures the bullet's position is updated in sync with the tank's movement.
