FleksNoSuchEntityComponentException: Entity has no component of type 'BComponent'. #125
Description
Hello,
Is it a bug or am I doing something wrong?
I add Component (name = BComponent) to Entity and in System class itterating over entities with BComponent is running.
I can check if Entity has a BComponent: entity.has(BComponent) = true
But if I call entity.get(BComponent), it will stops with FleksNoSuchEntityComponentException.
I suppose if "entity.has(BComponent)" is true, then "entity.get(BComponent)" should be not null or Exception.
Output in my console:
CmpSystem One onTickEntity
CmpSystem Two onTickEntity
entity.has(BComponent) = true
Exception in thread "main" com.github.quillraven.fleks.FleksNoSuchEntityComponentException: Entity 'Entity(id=0, version=0)' has no component of type 'BComponent'.
