eval Random Int provided Functions

[Tom Peak]

Hey,

I am making an SVG Audio Realtime Visual Programming Tool in Blockly. (Blocks like Circle/Line )

So basics works out, but I am stuck with eval provided function. fE. random int value should be pasted eval into a JSON- object with sets up SVG attributes by a function on run. (Property-Block inside a fE. LineBlock - inside a MainLoop)

It must be some basic js stuff, sorry, but I don't know how to deal with it…

Thx,

Tom

Blockly.JavaScript['property'] = function(block) {

  var text_prop = block.getFieldValue('PROP');

  var value_value = Blockly.JavaScript.valueToCode(block, 'VALUE', Blockly.JavaScript.ORDER_ATOMIC);

  // TODO: Assemble JavaScript into code variable.

  var value_value = eval(value_value);

  var code = '"'+text_prop+'":"' + value_value + '",';

  return code;

};

Blockly.JavaScript['circle'] = function(block) {

  var text_name = block.getFieldValue('NAME');

  var dropdown_typeX = block.getFieldValue('POSX');

  var value_x = Blockly.JavaScript.valueToCode(block, 'X', Blockly.JavaScript.ORDER_ATOMIC);

  var dropdown_typeY = block.getFieldValue('POSY');

  var value_y = Blockly.JavaScript.valueToCode(block, 'Y', Blockly.JavaScript.ORDER_ATOMIC);

  var value_r = Blockly.JavaScript.valueToCode(block, 'R', Blockly.JavaScript.ORDER_ATOMIC);

  var statements_attr = Blockly.JavaScript.statementToCode(block, 'ATTR');

   value_r = eval(value_r);

   value_x = eval(value_x);

   value_y = eval(value_y);

  // TODO: Assemble JavaScript into code variable.

  var code = "createObj('"+ text_name  + "','circle',{" + statements_attr  + "'id':'"+ text_name +"','"+dropdown_typeX+"':'"+ value_x +"','"+dropdown_typeY+"':'"+ value_y +"','r':'"+ value_r +"'})";

  return code;

};

console r= randomInt Math Block:

mathRandomInt is not defined

statementToCode?

 This is my code.

Can I ask why you are eval'ing the results of the inputs, and then immediately concatenating the results to a string (recreating the string version of the value)?

Normally, a generator will just concatenate the valueToCode() string result so that the return code will be evaluated once as a whole.

Yeah, thx, i got that now, I am into it. Code is "on the fly" … :) Kind against my prerender logic but I deal with it and it works out!

Making progress, It's real fun! Controlling another Window is against security, that one thing i work on later and exporting a "Patch" or how we call this? Blockly Code or … Programm as File for a External-Player. (VJ Channel)

Thx andrew, keep in contact!
