Hello!

Sounds like you're looking for the Blockly.serialization.blocks.append method =) (to replace Blockly.Xml.appendDomToWorkspace)

I hope that helps! If you have any further questions please reply!

Hi Beka, i have a small query, i am able to add the required block, but i am not able to add it to the desired position. My required position is, insert at last of all existing blocks, just like appendDomToWorkspace works. Can you give me some hint on this.

Hello!

Sorry for the late reply, looks like I missed this one. The JSON system doesn't have any built-in support for doing the exact thing that `appendDomToWorkspace` does. But there's no reason you can't implement it yourself.

Here's the source code for appendDomToWorkspace, the same basic steps of:

  - Get the bounding box

  - Deserialize the new blocks

  - Move them outside the bounding box

Will apply when using the JSON system. And this also gives you more control of how your blocks are positioned! E.g. they don't all have to be aligned vertically, they could be aligned horizontally or clustered into a square, etc.

If there is a lot of desire for this functionality, we may also consider adding it as a plugin!

I hope that helps! If you have any further questions please reply =)
