comment How to calculate falling and accelerating velocity?
@Patrick Hughes: Shuttle gross weight: 240,000lb. Total liftoff weight: 4,500,000lb. Admittedly, that includes 58,500 pounds of tank & 400,000lb of SRB. Still, though, you'll get more than 10x the acceleration from the last pound of fuel than from the first.

comment How to calculate falling and accelerating velocity?
@Patrick Hughes: The amount of fuel carried by any true rocket lander (I'm not counting the Mars aerobrake/rocket hybrid cases) is a substantial portion of it's total weight. Assuming the fuel:acceleration ratio to be fixed will produce a very wrong answer.

comment How to calculate falling and accelerating velocity?
@daemonfire300: You misunderstand--I'm not talking about the effect of running out of fuel, but the effect of burning fuel. A constant throttle setting on your engine produces a continuously climbing acceleration figure, a constant acceleration produces a continuously declining fuel burn rate. This means the simple calculations that FxIII gives will produce incorrect fuel use numbers.

comment How to implement zombie AI?
@Dukeofgaming: How do you get that? The broom isn't going to push them and if you're that close they'll be trying to attack you. Give them a long sense range if you want but zombies are not intelligent, don't give them intelligence in hunting.

@Lo'oris: I mean that it should evaluate the distance from squares by the straight-line distance, not the minimum path.
