简单四方向a*寻路学习记录2 先做个数组地图 在cocos编辑器模式上运行出格子 计算角色世界坐标跟数组地图的联系

用绿色表示目的地 在数组上0是空 1是目的地

用星星表示角色 计算星星node的世界position跟数组地图的联系

@property
    gridWidth: number = 10;  // 水平格子数
    
    @property
    gridHeight: number = 10; // 垂直格子数
    
    @property
    cellSize: number = 100;   // 每个格子的大小（像素）

// 在gezi.ts中添加一个**可靠的**坐标转换方法
public worldPositionToGrid(worldPos: Vec3): { x: number, y: number } {
    const gridWorldPos = this.node.getWorldPosition();
    const offsetX = worldPos.x - gridWorldPos.x;
    const offsetY = worldPos.y - gridWorldPos.y;
    
    // DEBUG: 打印调试信息
    console.log("=== 坐标转换调试 ===");
    console.log("1. 网格中心：", gridWorldPos);
    console.log("2. 角色位置：", worldPos);
    console.log("3. 偏移量 offsetX=", offsetX, "offsetY=", offsetY);
    
    // 网格半宽/半高 (注意：这里有坐标轴方向问题)
    const halfWidth = (this.gridWidth * this.cellSize) / 2;
    const halfHeight = (this.gridHeight * this.cellSize) / 2;
    
    // Cocos Y轴向上为正，但数组通常是左下角为(0,0)
    // 所以需要调整Y轴方向
    const gridX = Math.floor((offsetX + halfWidth) / this.cellSize);
    const gridY = Math.floor((offsetY + halfHeight) / this.cellSize);
    
    // Y轴翻转（因为屏幕上方是正Y，但数组从上到下索引）
    const flippedY = (this.gridHeight - 1) - gridY;
    
    console.log(`4. 计算：gridX=${gridX} (${offsetX}+${halfWidth})/${this.cellSize}`);
    console.log(`5. 计算：gridY=${gridY} (${offsetY}+${halfHeight})/${this.cellSize}`);


    console.log(`6. 翻转后：gridX=${gridX}, flippedY=${flippedY}`);
    console.log(`7. 结果：[${this.gezi[flippedY][gridX]}]`);

    
    // 使用 flippedY 因为数组是从上到下存储
    return { x: gridX, y: flippedY };
}

这里y轴得翻转 不翻转 角色在的格子跟计算世界坐标转数组格子是镜像

然后画格子

drawGrid() {
        if (!this.graphics) return;
        
        // 清空之前的绘制
        this.graphics.clear();
        
        // 设置线条样式
        this.graphics.lineWidth = this.lineWidth;
        this.graphics.strokeColor = this.lineColor;
        
        // 首先填充背景色
        this.graphics.fillColor = this.fillColor;
        
        // 计算网格的总宽高（用于居中显示）
        const totalWidth = this.gridWidth * this.cellSize;
        const totalHeight = this.gridHeight * this.cellSize;
        
        // 设置绘制原点在节点中心（Cocos默认）
        // 也可以从左上角开始画，看个人习惯
        
        // 绘制每个格子的填充背景
        for (let x = 0; x < this.gridWidth; x++) {
            for (let y = 0; y < this.gridHeight; y++) {
                let huoqugezi=this.gezi[y][x];
                // 然后反转Y坐标，让第一行显示在最上面
                const screenY = this.gridHeight - 1 - y;

                const posX = (x - this.gridWidth/2) * this.cellSize;
                //const posY = (y - this.gridWidth/2) * this.cellSize;
                const posY = (screenY - this.gridHeight/2) * this.cellSize;
                if(huoqugezi==1){
                    this.graphics.fillColor = this.zhangaiColor;
                    //this.graphics.rect(posX, posY, this.cellSize, this.cellSize);
                    
                    console.log(huoqugezi+"shi");
                }else if(huoqugezi==7){
                    this.graphics.fillColor = this.jueseColor;
                    //this.graphics.rect(posX, posY, this.cellSize, this.cellSize);
                    
                    console.log(huoqugezi+"shi");
                }
                
                else{
                    this.graphics.fillColor = this.fillColor;
                }

                    
                    
                
                this.graphics.rect(posX, posY, this.cellSize, this.cellSize);
                    console.log(huoqugezi);
                    this.graphics.fill();
            }
            
        }

// 然后反转Y坐标，让第一行显示在最上面

const screenY = this.gridHeight - 1 - y;

            const posX = (x - this.gridWidth/2) * this.cellSize;
            //const posY = (y - this.gridWidth/2) * this.cellSize;
            const posY = (screenY - this.gridHeight/2) * this.cellSize;

在cocos画出来是最后一行最右是1

应该是第一行最右是1
