This is an experimental study project to identify feasibility of Flexible Interceptor Missile (FLINT) in WiC game engine, to be used as an advanced AIR-TO-AIR missile, launched by future fighter jets such as F-22, Su-27, etc.

Because of the need for sophisticated guidance mechanism, we need the missile to be a unit -- where it can perform various calculations and establish data-link with launch platform.

I'm using the Mi-24V Hind as a temporary place holder, instead of using a real rocket/missile body for the model, so excuse the weirdness. For testing purposes, the depicted "missile" in this video uses simple pure-pursuit, tail-chase homing -- nothing different from WiC's vanilla homing rocket in this instance. Proportional navigation guidance law would be implemented for the real version.

There are some very important features to notice that differ from vanilla WiC's homing projectiles:

1. Rocket acceleration and inertial velocity simulation is provided -- the missile starts out slow, accelerates as it boosts, then gradually slows down as it coasts after completion of powered flight.
2. G-loading and energy simulation for rocket projectile in motion. As rocket is committed to turn, based on turning radius, more energy is spent, further degrading the rocket's ability to maneuver into its target. Also, overloading the G limit beyond the missile's design rating will cause the rocket to self-destruct.


The big problem with this project is whether it is feasible to be conducted over multiplayer over the network, because the projectile in motion is simulated on every frame, instead of using event polling to update the positions.

The next round of tests for this project is to test this under a network/multiplayer environment to verify how it performs on a client-server environment. That will probably determine this experimental project's fate/outcome in future development cycles.
