Problem differentiating between events

riacheslav

Hi,

My event is firing and it looks to have the correct data, yet I can't get it to work quite right.

private void addListeners() {
        final EventData smash_impact_Event = Assets.instance.playerSkeletonData.findEvent("smash_impact");
        animationState.addListener(new AnimationStateAdapter() {
            public void event (int trackIndex, Event event) {
                Gdx.app.error(TAG, event.getData() + ", "+smash_impact_Event );      //Fires, appears to be equal
                if (event.getData() == smash_impact_Event) {
                    Gdx.app.error(TAG, "yes");      //NEVER FIRES!!
                }
            }
        });
    }

So that first error message prints "smash_impact, smash_impact"

and if I ask it for toString() instead, or any number of other things, they look like the same. Yet the following if statement never resolves to true.

Thanks,
Richard

But this works:

animationState.addListener(new AnimationStateAdapter() {
           public void event (int trackIndex, Event event) {
               if (event.getData() == Assets.instance.playerSkeletonData.findEvent("smash_impact")) {
                   Gdx.app.error(TAG, "This displays, if is true...");
               }
           }
       });

So I have some Java scoping issue? I know it is remedial, but can anyone esplain to me? Would be much appreciated, thank you.

Pharan

In the version above, smash_impact_Event is a local of the method.
In the version below it's resolved inside the anonymous class implementation of the event method definition in the new AnimationStateAdapter.

I'm not sure how Java handles closures (lambdas/anonymous methods/classes capturing variables and values outside of itself). You should totally look that up if you're into syntax of anonymous/inline stuff.
But it may be less ambiguous and more structured if you don't use an anonymous class, and just make an actual class that implements AnimationStateListener to pass to addListener().

That's just my thinking as a C# guy. Could be totally wrong. Maybe this is the way to do it in Java.
