Testing framework for latency compensation

[Joris-van-der-Wel]

It is very tricky to get the various latency compensation methods working smoothly. Methods include:

• Ship render delay
• Projectile render delay converging to the delay of nearby ships (perception filter)
• Dead reckon
• Dead reckon convergence
• Timewarping of incorrect predictions

These methods have various settings and can also be disabled.

This is mostly about human perception, so unit tests are of very limited use.

What would be more useful is a framework that lets you define a short gameplay scenario, wherein the non local actors are lagged. A scenario includes:

• Local actor without latency
• Actors with latency
• Various operations with a specific time value performed by the actors
• Game (arena) settings. (varies between one hit kill, super zones, svs, etc)

The tester is able to launch a scenario using a button press, which will then play out in a lwjgl window, using as much existing code from aphelion as possible. This tool might also be used by server operators to tweak their latency compensation settings for their specific game settings

Framework has been made and some methods for making timewarps less obtrusive have been made in:
