};Blocks can be initialized with parameters when loaded with RoboBlocks.load({...});, and this parameters are available in options variable.
this.appendDummyInput('')
.appendTitle('Servo')
.appendTitle(new Blockly.FieldImage(
'img/blocks/bqservo01.png',
208 * options.zoom,
126 * options.zoom)
);Default profiles are available and defined in src/profiles.js. This profiles are available in profiles variable.
this.appendDummyInput('')
.appendTitle('Servo')
.appendTitle('PIN#')
.appendTitle(
new Blockly.FieldDropdown(profiles.default.digital),
'PIN'
);Blocks images should be defined like this:
this.appendDummyInput('')
.appendTitle(new Blockly.FieldImage(
'img/blocks/bqservo01.png',
208 * options.zoom,
126 * options.zoom)
);And its images stored in src/blocks/[block_name]/img/[filename].png.
When the project is compiled, all images are located in dist/img/blocks/*.png.
Blocks code are defined in *.c.tpl files as an underscore templates but with following settings:
templateSettings: {
evaluate: /\{\{#([\s\S]+?)\}\}/g, // {{# console.log("blah") }}
interpolate : /\{\{\{(\s*\w+?\s*)\}\}\}/g, // {{ title }}
escape : /\{\{(\s*\w+?\s*)\}\}(?!\})/g // {{{ title }}}
}With this settings, this template called servo_move.c.tpl:
servo_{{ dropdown_pin }}.write({{ value_degree }});
delay({{ delay_time }});
When evaluated like this:
var code = this.JST['servo_move']({
'dropdown_pin': 3,
'value_degree': 180,
'delay_time': 1000
});Will generate the following code:
servo_3.write(180);
delay(1000);
