Question

我正在编写一个批处理脚本，使用TexturePacker的命令行工具生成精灵表。

for /f "delims=" %%i in ('dir /b sprites') do (
    TexturePacker --format "json" --data "sheets/%%i.json" --sheet "sheets/%%i.png" "sprites/%%i"
)

到目前为止非常简单，但我想知道是否有可能从该工具生成[* .tps]文件。因此，如果有人想要检查导出的属性，他们可以通过TexturePackerGUI来完成。

Answer 1

这是我用来在文件夹中构建所有.tps文件的bash脚本：

#!/bin/bash
for i in *.tps; do TexturePacker assets/texture_packer/$i; done

Answer 2

此批处理脚本在文件夹中生成所有* .tps：

const topZero = 0;
const parent = i => ((i + 1) >>> 1) - 1;
const left = i => (i << 1) + 1;
const right = i => (i + 1) << 1;

class PriorityQueue {

  constructor(comparator = (a, b) => a > b) {
    this._heap = [];
    this._comparator = comparator;
  }

  size() {
    return this._heap.length;
  }

  isEmpty() {
    return this.size() == 0;
  }

  peek() {
    return this._heap[topZero];
  }

  push(...values) {
    values.forEach(value => {
      this._heap.push(value);
      this._siftUp();
    });
    return this.size();
  }

  pop() {
    const poppedValue = this.peek();
    const bottom = this.size() - 1;
    if (bottom > topZero) {
      this._swap(topZero, bottom);
    }
    this._heap.pop();
    this._siftDown();
    return poppedValue;
  }

  replace(value) {
    const replacedValue = this.peek();
    this._heap[topZero] = value;
    this._siftDown();
    return replacedValue;
  }

  _greater(i, j) {
    return this._comparator(this._heap[i], this._heap[j]);
  }

  _swap(i, j) {
    [this._heap[i], this._heap[j]] = [this._heap[j], this._heap[i]];
  }

  _siftUp() {
    let node = this.size() - 1;
    while (node > topZero && this._greater(node, parent(node))) {
      this._swap(node, parent(node));
      node = parent(node);
    }
  }

  _siftDown() {
    let node = topZero;
    while (
      (left(node) < this.size() && this._greater(left(node), node)) ||
      (right(node) < this.size() && this._greater(right(node), node))
      ) {
      let maxChild = (right(node) < this.size() && this._greater(right(node), left(node))) ? right(node) : left(node);
      this._swap(node, maxChild);
      node = maxChild;
    }
  }
}

从命令行工具生成（* .tps）？
