Hello, first of all, thanks for all your help. I had another question about waiting time between blocks.

So I have this code:

function runCode() {

// Generate JavaScript code and run it.

window.LoopTrap = 1000;

Blockly.JavaScript.STATEMENT_PREFIX = 'highlightBlock(%1);\n';

Blockly.JavaScript.addReservedWords('code');

var code = Blockly.JavaScript.workspaceToCode(workspace);

Blockly.JavaScript.INFINITE_LOOP_TRAP =

'if (--window.LoopTrap == 0) throw "Infinite loop.";\n';

Blockly.JavaScript.INFINITE_LOOP_TRAP = null;

var myInterpreter = new Interpreter(code);

nextStep();

try {

eval(code);

} catch (e) {

swal(e);

}

};

and my nextstep() is defined as

function nextStep() {

if (myInterpreter.step()) {

window.setTimeout(nextStep, 5000);

}

};

I want to have 5 seconds pause between executing each block. However, when I run this code, it gives me this error:

Uncaught SyntaxError: Unexpected token (2:49)

at c (acorn_interpreter.js:2)

at N (acorn_interpreter.js:16)

at v (acorn_interpreter.js:15)

at ha (acorn_interpreter.js:24)

at ha (acorn_interpreter.js:25)

at Sa (acorn_interpreter.js:24)

at Qa (acorn_interpreter.js:22)

at A (acorn_interpreter.js:22)

at F (acorn_interpreter.js:20)

at Object.a.parse (acorn_interpreter.js:29)

Can somebody help me with this? Thanks a lot!

I am also facing this as well as some other weird behavior:

By just doing these lines, the interpreter automatically runs:

var code = Blockly.JavaScript.workspaceToCode(Blockly.mainWorkspace);

var myInterpreter = new Interpreter(code);

This causes the "nextStep()" function to not have any effect since the interpreter has already run the code. Any solution to that?

 const runCode = () => {
    const code = javascriptGenerator.workspaceToCode(ws);
    console.log(code)
    const myInterpreter = new Interpreter(code, (interpreter, scope) => {
      interpreter.setProperty(scope, 'moveForward', interpreter.createNativeFunction((steps) => {
          moveForward(steps);
      }));
      interpreter.setProperty(scope, 'moveBackward', interpreter.createNativeFunction((steps) => {
          moveBackward(steps);
      }));
      interpreter.setProperty(scope, 'moveUp', interpreter.createNativeFunction((steps) => {
          moveUp(steps);
      }));
      interpreter.setProperty(scope, 'moveDown', interpreter.createNativeFunction((steps) => {
          moveDown(steps);
      }));
    });

    function nextStep() {
      if (myInterpreter.step()) {
          setTimeout(nextStep, 150);
      }
  }

  nextStep();
  };

I did it this way and it worked
