The Second Nastyish Problem

I now have the critical part of the batching portion working. Objects are decomposed to their smallest constituant parts which can then be rendered in groups. The actual grouping is still to be done but that's relatively straigtforward. I want to be able to measure how slow/fast I'm making my game's graphics before diving in to some hardcore algorithm hacking.

The next nasty problem for me to deal with is the issue of getting the game's controls working across multiple objects. For example, the player's fighter can be composed of a hull, a few guns and several thrusters. Input would need to be affect only relevant objects without causing weird side-effects in the others.

This problem is half solved currently. A single controller object, which is responsible for receiving and processing input from somewhere into actions. Any entity can attach itself to the controller and alter its state based on input from the controller.

A thruster, for example, can decide whether it should turn on based on whether the controller is saying "turn left" or not. This nicely addresses the issue of getting weapons firing in groups, thrusters firing appropriately and so on.

The second half of the problem isn't so easily resolved however. I also have to get state data from the enties that are attached to the controller back to the controller so that they can be sent to the network. My other option is to send complete object state data directly from each entity to/from the network, however that defeats the original purpose of the controller.

An additional problem I didn't quite want to solve this early, but have to, is getting the in-game physics working. This is due to my choice of controlling fighters via believable application of thrust and counter-thrust.

Plenty to mull over. I probably won't have a solution until the end of this week at earliest.
