Hi Friends,

I am new to coding so sorry if this is a super simple question. I am trying to remove only one entity when collision occurs. However I can’t seem to remove one without removing all of the same type.

Ex:
onCollidedWithBox:{
entityManager.removeEntitiesByFilter([“box”]);
}

I know I can use entityManager.removeLastAddedEntity() but this will not work in my case because it may grab another entity that just spawned.

Any help is appreciated, and again sorry for my noobness.
Thanks

Hi Wilfred,

just call the removeEntity() function of the specific entitiy that you want to remove.

Hi Wilfred!
Don’t worry, everyone has to start somewhere 😉

As an alternative to Alex’s suggestion, you can also use the EntityManager::removeEntityById function. Each entity has a unique entityId, which you can use to retrieve the entity object or remove the entity.

Günther

Hey Guys,

I found success using the EntityManager::removeEntityById function. But I am having an issue where an entity of the same type will spawn before the first entity object is removed which causes the second entity object to have a different entityId. I am unsure how to retrieve this entityId or even set it. Therefore I cannot remove the second entity object because it is using a different entityId.

I wish to keep the entity objects spawning one after the other before the first object collides and gets removed.

Any suggestions on how to solve this?

Thanks again,
Wilfred

Hi,

You can try to use getLastAddedEntity to get that entity and then read its entityId property.
