我正在用块创建程序。我已从this github location进行块下载，并且尝试替换从此位置https://blockly-demo.appspot.com/static/media/sprites.png到此（相对）位置sprites.png的块图像路径。但我不知道该怎么做。
问题是：在哪里可以设置此路径？
这是我的页面代码（在blockly的根文件夹中：
<!DOCTYPE html>

<div id="blocklyArea" style="position: absolute; width: 100%; height: 100%;"></div>
<div id="blocklyDiv" style="position: absolute;"></div>
<script>
var blocklyArea = document.getElementById('blocklyArea');
var blocklyDiv = document.getElementById('blocklyDiv');
var workspace = Blockly.inject(blocklyDiv, {toolbox: document.getElementById("toolbox")});
var onresize = function(e) {
// Compute the absolute coordinates and dimensions of blocklyArea.
var element = blocklyArea;
var x = 0;
var y = 0;
do {
x += element.offsetLeft;
y += element.offsetTop;
element = element.offsetParent;
} while (element);
// Position blocklyDiv over blocklyArea.
blocklyDiv.style.left = x + 'px';
blocklyDiv.style.top = y + 'px';
blocklyDiv.style.width = blocklyArea.offsetWidth + 'px';
blocklyDiv.style.height = blocklyArea.offsetHeight + 'px';
Blockly.svgResize(workspace);
};
window.addEventListener('resize', onresize, false);
onresize();
Blockly.svgResize(workspace);
//document.body.innerHTML = document.body.innerHTML.replace(/https:\/\/blockly\-demo\.appspot\.com\/static\/media\/sprites\.png/gi, "sprites.png");
</script>

对不起，英语不好。
您可以在批量注入时更改介质路径。进行media option通话时，请参考Blockly.inject()。
根据您的情况，您可以执行-->
var workspace = Blockly.inject(blocklyDiv, {toolbox: document.getElementById("toolbox"), media: './'});
