systems communication about ash

[richardlord]

1. The architecture of Ash is such that systems take it in turns to do their processing. They don't talk to each other because if they did so the listening system would act out of sequence. Systems use an manipulate the data in the components. The CollisionSystem doesn't have to remove the game objects, it could set a property in the SpaceShip's components that indicates a collision, perhaps incrementing a number that represents the amount of damage sustained. Other systems (your AISystem) can in turn respond to that data by deciding how it affects the SpaceShip.
2. If you follow the architecture I've described in the previous answer, you'll find that you do want to call the AISystem from the game loop. The update call from the game loop is the only chance a system has to do any processing at all.
