public void setHasStung(boolean p_27926_) {
      this.setFlag(4, p_27926_);
   }

I have set setHasStung to public, however it still seems to not let me call the method. I'm trying to make it so that bees can sting you, but will not lose their stinger and die:
 

@SubscribeEvent
        public static void unSting(LivingHurtEvent e) {
            if (e.getSource().getEntity() instanceof Bee) {
                ((Bee)e.getSource().getEntity()).setHasStung(false);
            }
        }

setHasStung is just underlined red, can anyone explain this? Thank you

 

Update: setHasStung is still seen as private in the subscribe event, the change has not been recognised, how do I fix this?

show the AT and your build.gradle file,
did you refresh the dependencies?
