I have this code:

    function exitGameScene() {
        /*
        var platforms = entityManager.getEntityArrayByType("platform")
        for (var i=0, platform; platform=platforms[i++];) {
            platform.removeEntity()
        }
        var keys = entityManager.getEntityArrayByType("key")
        for (var i=0, key; key=keys[i++];) {
            key.removeEntity()
        }
        */

        entityManager.removeAllPooledEntities()

As you can guess, platforms and keys are the pooled entities that I have.

The commented section does what I need, but the call to removeAllPooledEntities() does not.

I can see removeAllPooledEntities() doing this:

qml: EntityManager: removeAllPooledEntities()

qml: EntityBase: onDestruction(), emit entityDestroyed signal for entityId platform_9

qml: EntityManager: just removed static entity defined in QML file with id platform_9 and type platform from active entities

yet when I do it this way, the image of the platform remains in the level next time the level is activated.

(The platform itself is not present next time: it does not affect the level in anyway, it is just drawn – which is why I am doing this removal in the first place).

This is not the case when I do the individual removeEntity() calls.

What’s going on there?

Update: actually, neither of these work reliably – it turns out in both instances I sometimes get visual artifacts from the finished level on the next level 🙁

For the record, I’m now doing this, to get rid of “hangover images” on the next level:

    function exitGameScene() {
        // Have to do this, to ensure they aren't on the screen next time
        var platforms = entityManager.getEntityArrayByType("platform")
        for (var i=0, platform; platform=platforms[i++];) {
            platform.x = -platform.width
        }
        var keys = entityManager.getEntityArrayByType("key")
        for (var i=0, key; key=keys[i++];) {
            key.x = -key.width
        }

 

It’s obviously not “right”, but I can’t tell if the problem is bad use of Felgo by me, or a bug in Felgo!   At least it seems to be working…

Hi Martin,

Pooled entities are entities that got created, then destroyed and are now waiting in the pool for re-use. So removeAllPooledEntities() will remove those, but will not affect any active entities.

Calling removeEntitiy() on an entity will do one of 2 things:

• If the entity has poolingEnabled set to true (and also the EntityManager has poolingEnabled set to true), then the entity will disappear and be moved to the pool for re-use
• If pooling is not enabled, the entity will be completely destroyed and disappear

Cheers,
Alex
