I am new to using Farseer Physics Engine 3.2(FPE), so please bear with my questions. Also, since FPE 3.2 is based on Box2D, I have been reading Box2D manual and pieces of code scattered in samples to better understand terminology and usage.
Pong is usually my testbed whenever I try to do something new. Here is one of the issue I am running into:
How can I restrict paddles to move only along Y axis, because the ball comes in and knocks off the paddles and everything floats in space afterwards ? (Box = Rectangle and ball = circle)
I know MKS is the unit system, but is there a recommendation for sizes/position to be used ? I know this is a very generic question, but it would be good to know a simple set of values that one could use for making a game as simple as pong.
Between box2d and FPE, I have some doubts:
what is the recommended way of making a body in FPE ?
- world.CreateBody() does not exist in FPE
- Box2d manual recommends never to "new" body(since Box2D uses Small Object allocators), so is there a recommended way in Farseer to create a body (apart from factories) ?
- In box2d, it is recommended to keep a track of the body object, since it is also the parent to fixture(s). Why is it that in most of the examples, the fixture object is tracked ? Is there a reason why body is not tracked ?
