Question

I have been looking over this doc:

http://andengine-doc.googlecode.com/hg/org/anddev/andengine/entity/modifier/SequenceEntityModifier.html

And it indicates that there is an onUpdate, but I’m seeing this error when I try to use it:

The method onUpdate(float) from the type new
SequenceEntityModifier(){} is never used locally

I’m new to Java, here is my code:

    SequenceEntityModifier modifier = new SequenceEntityModifier(myMovemod) {

        @Override
        protected void onModifierFinished(IEntity pItem) {
            // animation finished
            super.onModifierFinished(pItem);
        }

        protected float onUpdate(float pSecondsElapsed) {

            return pSecondsElapsed;

        }

    };

When I add “@Override” to it, I get an error, and eclipse’s only solution is to remove @override, What am I doing wrong here?

Answer 1

Based on the javadoc in your original question, I think the method should look like:

public float onUpdate(float pSecondsElapsed, IEntity pItem)
{
    return pSecondsElapsed;
}

Otherwise you are not overriding an existing method – you are creating a new method.

Also onModifierFinished should be public.
