Finding location area of TextNode

Scripting Issues
1

So I’m printing an array of strings in a circle and Ideally I’d like to click on them so I can do further action. However the setPos() doesn’t seem to set the text where it should. If it did I would just find the area I can click on using the intial setPos coordinantes and string size to determine if I clicked on the string or not. However its not placing the strings in the desired location. Any thoughts why that might be?

If I recall correctly, the coordinates of mouse-events don’t match those of aspect2d (to which your text is, I believe, parented). Specifically, I believe that they match render2d, and thus have the range [-1, 1] in both the vertical and horizontal axes. You can convert between the two, I believe, such as by getting aspect2d’s scale relative to render2d, or simply using methods like “NodePath.getRelativePoint()”

However, there may be an easier way, depending on your requirements: if you make the strings into DirectButtons, you should be able to simply set a command to be called when they’re clicked on. If you don’t want them to look like buttons, you can change their “relief” mode when constructing them. For information on DirectButton, see here; for information on the relief modes, see here.
