VisUI & Libgdx 1.9.9 & DragAndDrop & null problem
Closed this issue · 4 comments
When i use 1.9.8 everything work fine, but after update libgdx to 1.9.9, every use of dragAndDrop in game end like this:
Exception in thread "LWJGL Application" java.lang.NullPointerException
at com.badlogic.gdx.scenes.scene2d.utils.DragAndDrop$1.drag(DragAndDrop.java:104)

DragAndDrop changed in 1.9.9, dragged actor is removed when its dragged. This caused me issues as well.
I'm not seeing any VisUI calls in the stack trace so not sure why this is reported here. IIRC VisUI doesn't even use DragAndDrop from libGDX.
Closing as no further explanation or example was provided.
