Transform a matrix blocks of fields into a matrix block of input

[Jean]

Dear Blockly community,

I have a block that create a matrix of éléments from fields, and today i want to modify it so it has input instead of fields so i can put any types of block.

So this is the code of the matrix when i add a column:

addColumnFields: function() {

    for (var j = 0; j < this.dimY; j++) {

      this.line[j].appendField(new Blockly.Field(), "element_" + j +"_"+ this.dimX);

    }

},

I also tried to change it into input but it didn't succeed:

addColumnFields: function() {

    for (var j = 0; j < this.dimY; j++) {

      this.line[j] = this.appendValueInput("element_" + j +"_"+ i);

    }

},

Do you think it's possible ?

Any help at all would be greatly appreciated.

Thank you.

Hello!

The problem is that we have inline and external inputs. External inputs stack inputs vertically and inline line up inputs horizontally. We don't really offer a way to do both. I don't think our current renderer can handle this situation. You can look at creating a custom renderer.There is also a plugin that allows you to add/remove inputs using a +/- button on the block. I know it isn't exactly what you are looking for, but might get you halfway there. 

Hope this helps!

Hello,

Thanks to your suggestion, i found a way to make the block that i wanted. I made a block that add an input vertically (lines) where i put another block that can add an input horizontally (columns).

Right now my code only add value input and i have to add those columns blocks manually, do you think i can append a block to directly in the code:

My code:

addPart_: function() {

    if (this.itemCount_ == 0) {

      this.removeInput('EMPTY');

      this.topInput_ = this.appendDummyInput('LINE_' + this.itemCount_)

          .appendField(createPlusField(), 'PLUS')

          .appendField(Blockly.Msg['TABLE_MATRIX_TITLE']);

    } else {

      this.appendValueInput('LINE_' + this.itemCount_).setAlign(Blockly.ALIGN_RIGHT);

    }

    this.itemCount_++;

  },

What i want:

addPart_: function() {

    if (this.itemCount_ == 0) {

      this.removeInput('EMPTY');

      this.topInput_ = this.appendDummyInput('LINE_' + this.itemCount_)

          .appendField(createPlusField(), 'PLUS')

          .appendField(Blockly.Msg['TABLE_MATRIX_TITLE']);

    } else {

      this.appendValueInput('LINE_' + this.itemCount_).setAlign(Blockly.ALIGN_RIGHT).append(new Block column...);

    }

    this.itemCount_++;

  },

Do you think it's possible ?

Any help at all would be greatly appreciated.

Thank you.

Hello!

Sorry for the late reply! You should be able to do something like below: 

const input = this.appendValueInput('LINE_' + this.itemCount_)

const newBlock = new Block column...

input.connection.connect(newBlock.outputConnection)

Hope this helps and let me know if you have any other questions!
