How to apply translation on imported nodes ? #661

Open oanguenot opened 1 year ago

oanguenot commented 1 year ago

Hi, I have a lot of nodes on the canvas and I want to add new ones on the top of all other nodes. For that, I translated the canvas to have space available on top. The problem is when saving and reloading the nodes, the translation done is applied.

Is there a way to that ? Thanks in advance

Hello,

I don't know if I quite understand what you want.

Do you want to move the nodes on import? Or move the canvas when importing?

If I have a canvas full of nodes, I want to move the canvas to the bottom (drag it to the bottom) and then add new nodes on the top of the screen. Then I save the editor (export). If I reimport it, the new nodes added are not visible on screen. I need to drag the canvas again to the bottom to see them.

Perhaps I didn't have correctly understood how to use the "translate" event fired when the canvas is moved.

So, if I save the translate result, how to re-inject it to the canvas once imported to restore it ?

Hello,

You can save the variables:

editor.canvas_x;
editor.canvas_y;

And you can use this method to translate to specific coordinates.

You can use the import event to detect when the data is finished loading and call the function.
