Moreso then usual. So I\'ll just copy a post I made here too:
(is regarding a jump drive, an instantaneous system).
Basically, to use it, you need to input a destination. You must then wait a short time for the drive to charge before you teleport. During this charging period, your thrusters, weapons, and shields all go offline, making you very vulnerable if someone were to attack you (or if they already were attacking you, in particular). Shields would have to recharge from zero as well upon entering the destination sector.
How far you can jump is based upon how many jumpdrive blocks you have, with diminishing returns but NOT weighted against your ship size. So larger jumpdrives always can jump farther (and thus larger vessels will tend to be able to as well). And can still do so with vessels docked to them.
How long the charging period is is based on the jumpdrive block number, but IS weighted against your ship size and has mild dimishing returns as well. So larger ships with 5% of their blocks dedicated to jump drive will always take longer then smaller ships with 5% of their blocks in a jump drive, for instance.
So a small fighter may only take 5 seconds or so to jump. Maybe even less if its designed specifically for jumping. A frigate may take 10-15 though, and a larger ship may take a good 20-30 seconds to charge (a REALLY REALLY big one may take up to 60). In other words, you do not want to be using it near enemies unless someone is either covering you or unless you know you are dead if you stay regardless.
There, a teleporting idea that doesn\'t interfere with combat or place irksome limits on ease of movement. That said, jumpdrives would be good for moving 5-10 sectors, but limit their max range to around 20-30ish and you can allow a jump gate or something like that to be the long range means of movement. (this post was originally made in a jump gate topic).
