Hi
I want to make a block which can load a txt file and can use the file's content.

I found helpful link to use file import block below
https://groups.google.com/forum/#!starred/blockly/grwyJKzRg60

I think it's possible in blockly, but I don't know how to use the block in that link in my espurino web ide project.

Can you help me?

Thank you Gordon!
It works perfectly with your solution.

The reason why I use validate is, when I don't choose any value in dropdown, so the default value should be set, but unfortunately it doesn't. The value was undefined when I don't select any value in dropdown!

if(motorValid_ === false) {
        motor_ = 0;  <-----------------------  here because motorValid never got set
    }
    else {
        motor_ = block.getFieldValue("turnMotor_") <--- never gets called

So that block.getFieldValue("turnMotor_") line works well, because of validator.

I can't think the way that just check what's going on when creating the code in Blockly.JavaScript.*.

Can you explain with any examples?

Hi Gordon!
Thanks for reply.

https://github.com/junguksim/project_codubot/blob/master/blockly/blockly_codubot.js
You can watch first block(codubot ready)'s code at first line.
Second block(motor_move)'s code is at line 178.

If you want more, please give me reply.

Hello there.
I'm developing a site which can control an educational robot(by MDBT42Q).

Here's my block code that I want to save and load.

(If you can't see photo, I attached at below.)
It looks simple. First dropdown has two options(LEFT, RIGHT) and LEFT is 0, RIGHT is 1.
Second dropdown has two also, CW is 0 , CCW is 1.

It's a converted javascript code.

/* motor_move function code */
motor_move(1, 0, 0, 0, false);
//motor_move's parameters : motor_move(motor, direction, velocity, angle, wait);

If I set 'RIGHT' motor at block code and save my code, and then I load it and convert, the code shows

motor_move(0,0,0,0,false);

So the loaded block code shows 'RIGHT' motor set, but actually robot moves 'LEFT' motor.

How can I save block code with right parameters that I set before?

Help me please!

Hi!
I have some problems.

var ir_adc = [0, 0, 0, 0, 0];

var ir_adc_loop = setInterval(function() {
  i2c.writeTo(0x0A, [1, 10]); i2c.writeTo(0x0A, [14]); var ir_i2c = i2c.readFrom(0x0A, 10);
  ir_adc = [((ir_i2c[0] * 256) + ir_i2c[1]),
        ((ir_i2c[2] * 256) + ir_i2c [3]), 
        ((ir_i2c[4] * 256) + ir_i2c [5]), 
        ((ir_i2c[6] * 256) + ir_i2c [7]), 
        ((ir_i2c[8] * 256) + ir_i2c [9])];
}, 10);

Here is my code for Espruino web ide. ( To get IR Sensor value)
So if I upload this code to robot,

>ir_adc
=[38,44,43,41,41]

I can get my ir_adc value.
But I want to get ir_adc value in my blockly_something.js.
Is there a solution to get IN-ROBOT value at my vscode SUPERCOOL?

Thank you.

Thank you Gordon!

Blockly.JavaScript.robot_move_angle = function () {
    var dir = Blockly.JavaScript.valueToCode(this, 'dir', Blockly.JavaScript.ORDER_ASSIGNMENT) || '""';
    var vel = Blockly.JavaScript.valueToCode(this, 'vel', Blockly.JavaScript.ORDER_ASSIGNMENT) || '""';
    var angle = Blockly.JavaScript.valueToCode(this, 'angle', Blockly.JavaScript.ORDER_ASSIGNMENT) || '""';
    var time = Blockly.JavaScript.valueToCode(this, 'time', Blockly.JavaScript.ORDER_ASSIGNMENT) || '""';
    return "robot_move_angle("+dir+","+vel+","+angle+","+time+","+"setTimeout("+MAGIC_CALLBACK_CODE+", 1000*"+time+")\n;"
}

I wrote my code like this, and I know that NEXT_BLOCK works well.
But it has an error.
error said :
You have more open brackets than close brackets. Please see the hints in the Editor window

But I changed front-end for my project, so I can't use editor window.
So I want to see codes when I push upload button at my terminal.

/upload.html

  function sendUploadedCode() {
    Espruino.Core.MenuPortSelector.ensureConnected(function() {
      Espruino.callProcessor("sending");
      Espruino.callProcessor("transformForEspruino", uploadCode, function(code) {
        Espruino.Core.CodeWriter.writeToEspruino(code, function() {
          Espruino.Core.Terminal.typeCharacters(code);
          Espruino.Core.Terminal.addNotification("Uploaded!");
        });
      });
    });
  }

I know upload button use this function, so I add one line,

Espruino.Core.Terminal.typeCharacters(code);

But it doesn't work. Is it possible to see uploaded codes at web ide's terminal??

Thanks for reply, Gordon!
Shamefully, I don't understand..
If you can, can you explain it by code?

Everything will be fine if there is a method that can verify if there is a nextBlock...

Hello.
My board is MDBT42Q, and it has some motors, IR sensor by i2c.
Everything is fine. Motors move well, IR sensors too.
But, my robot should move synchronous.

For example,

Blockly.Blocks.robot_move_angle = {
    category: 'CoduBot',
    init: function () {
        this.appendDummyInput()
            .appendField('로봇 각도로 움직이기');
        this.appendValueInput('dir')
            .setCheck(['Number'])
            .appendField('방향');
        this.appendValueInput('vel')
            .setCheck(['Number'])
            .appendField('속도');
        this.appendValueInput('angle')
            .setCheck(['Number'])
            .appendField('각도');
        this.appendValueInput('time')
            .setCheck(['Number'])
            .appendField('시간');
        this.setColour(150);
        this.setPreviousStatement(true);
        this.setNextStatement(true);
    }
}

Blockly.JavaScript.robot_move_angle = function () {
    var dir = Blockly.JavaScript.valueToCode(this, 'dir', Blockly.JavaScript.ORDER_ASSIGNMENT) || '""';
    var vel = Blockly.JavaScript.valueToCode(this, 'vel', Blockly.JavaScript.ORDER_ASSIGNMENT) || '""';
    var angle = Blockly.JavaScript.valueToCode(this, 'angle', Blockly.JavaScript.ORDER_ASSIGNMENT) || '""';
    var time = Blockly.JavaScript.valueToCode(this, 'time', Blockly.JavaScript.ORDER_ASSIGNMENT) || '""';
    return `robot_move_angle(${dir}, ${vel}, ${angle}, ${time})`;
}

It is my code.
There's a block for initialize, and it's compressed by memory problem.
So just init once, and return function execution code.
(I don't know this is the best.)

Anyway, If there are two 'robot_move_angle' blocks, and time is 2 sec and 4sec,
user will think that it will move 2 sec, and after 2 sec, it will move 4 sec.

But unfortunately, there's a crack, because of javascript's asynchronous.
Is there a solution?
