AI for Games, birth method problem

StefanW

Hi, since Quarks launched his brilliant AI_4_Games library I am testing it for a future project of a game. Until right now the lib was working just perfect, but now I am stuck with something. I am not having success using the world.birth(BaseEntity entity,double timeToBirth); method. We are not supposed to use world.add(...) after the setup (indeed, it crashes the program), but the birth method does seems to add a new MovingEntity.

I tried to look at the World.java code, and I may have fund the problem (or not). I think the if logic is wrong:

public void birth(BaseEntity entity, double timeToBirth){
if(entity != null && allEntities.containsKey(entity.ID())) 
          entityChangeList.add(new Changling(entity, timeToBirth, false));
}

It shouldn't be if(entity != null && !allEntities.containsKey(entity.ID())) ? Since the entity is not yet born, its ID should not be in allEnteties list.

Or am I doing something else wrong?

Thanks, StefanW

Hi StefanW

Glad to see you having a go with this library.

I have double checked the source code and can confirm that you are right..., I made a mistake :\">

If I understand the problem correctly it will not allow you to give birth to an entity unless it had been added in setup with world.add(...) - which obviously defeats the purpose - if is this correct then let me know and I will rush out a new version.

Hi Quarks,

that's right. I am trying to give birth to a new entity in the middle of the game, but the entity doesn't come to life. So I figured out it may be this logic problem on the world.birth(...) method. I would be very glad if you could fix that :D

Thanks, StefanW

You can download the latest version (1.0.1) from here

Thanks for reporting the bug but more thanks for identifying the problem code =D> - saved me a lot of bother.
