Error: Uncaught TypeError: Expecting string from statement block: customCode

[RunNow]

I dont know why does it not work...

here is my code..

Here is the brick definition.

Blockly.Blocks["customCode"] = {

  init: function() {

    this.appendValueInput("CODE")

      .setCheck("String")

      .setAlign(Blockly.ALIGN_RIGHT)

      .appendField("Custom Lua String:");

    this.setColour(160);

    this.setTooltip("Creates a custom Lua string.");

    this.setPreviousStatement(true);

    this.setNextStatement(true);

  }

};

Here is the code generator

Blockly.Lua['customCode'] = function(block) {

  var code = Blockly.Lua.valueToCode(block, 'CODE', Blockly.Lua.ORDER_NONE) || ' '

  console.log(code);

  return [code];

};

I hope someone helps

Hi,

If you return the string code instead of the 1-item Array [code], it should work.

Blocks producing a value require extra information about when parentheses around their generated code are necessary.  So for any value block generator, you have to return a 2-item Array with the string and a constant representing when to include the parentheses.  For example, for Lua, a block producing the code 2 * x would need parentheses around its generated code when nested inside a block that cubes its input to get (2 * x) ^ 3, but it would not need them if nested inside a block that adds 3 to its input to get 2 * x + 3.

Statement blocks such as print, do not need this extra information.  So the generator for any statement block should return a string instead of an Array.

Best,

Jason

Thank you so much!
