Hello,
at the moment I try to use Artemis and Slick2D for a small game.
But I have two problems:

1. How make an entity visible/renderable ?
And yes I have seen the demos, but I think that solutions are not perfect, because the spatial forms in for exmaple TankZ uses components from the owner entity that it maybe not has....
Or the spatial forms are created if they needed and destroyed if they are not used and they are initalized while you play, so it can be laggy while playing.
And at last, I dont like this solution, its doesent feels good to me, I think there is a better solution.

2. How to give an entity physics?
Thats a big problem to me, because if I give an entity a physics component with a body, the body have in the most collision libraries, like Box2D, his own position data, and a transform component that has his own position data, too.
Do you noticed something?
Yes, there are the same data at one entity twice.
How I handle this(synchronization), and I see often, that some people make extra one system(often called move system) that add the velocity to the transform, and than the collision system correct the position for example on collision, I think thats not efficient, too, or what do you think?

I hope some people can help me.
Yours sincerely Michael
