I am trying to do all the tutorials that the Gdevelop website offers.
Unfortunately, while I was trying to do the platformer tutorial I came across a problem
The tutorial says to add " Modify the text of a variable of an object" as an action, but as you can see in the picture I’m attaching no such option comes up
Yes, it is possible that particular parts of some tutorials are not up to date anymore - there were many changes in the last months. For your case you need to click on the object whose variable you want to change (or modify) and then go to “Text of an object variable” .
