I've asked this in the Ships & Module forum but someone hijacked my thread and I'm not sure Devs read that forum much so I'll ask here instead...
Could any DEV team member confirm the base formula that is used to calculate how much time it takes for a ship to go from 0m/s to warp? I'm not talking about skills, modules and other ship bonuses and I don't want to hear about them either. I want the pure, simple "stat A * stat B = time to warp" type of formula only.
I need to know so I can write a "time to warp" calculator.
Thanks in advance.
(please don't hijack my thread by adding to my question or passing comments, if you don't know just don't reply.)

Your best bet to get a reponse would probably be to evemail one of the GM's your question and see if they will pass it on to a dev for you as its for a tool and not some complaint or flame.. KALI:Revelations.. Putting the Waaaa back in Piwat.. |

Thanks for the advice, any GM in particular you think would be more responsive to such a request?

No idea.. Try them all.. But only once each.. I'd say evemail the Devs but I'm fairly sure they ignore all mail sent to them as it has to be in the hundreds a day.. KALI:Revelations.. Putting the Waaaa back in Piwat.. |

Edited by: James Lyrus on 27/11/2006 10:03:08 Seen what you're asking, and had a response about the factors involved.
I don't think the formula is published. Why not try some empirical testing on rates of turn/acceleration on the test server and figure it out for yourself.

Because I really suck at maths and I wouldn't be able to do it... hey, at least I'm honest about it lol. Besides I can't access the test server right now, my acount is not mirrored with the right status (mirrored while trial expired...)

No such formula exists. A ship - any ship - enters warp at either 2/3 max. speed or 3/4 max speed (I can't remember which). This of course does not count the time to align.
A side effect of this is that in theory if you get webbed before scrambled, your max. speed tops out and you warp instantly.
You can turn on a AB for one cycle, kick it off and go to warp almost the instant it turns off.
Ship speeds and acceleration are controlled by skills and modules.

Edited by: Xamys on 27/11/2006 16:07:17 There is a formula for sure, wether it's in the root code of the engine itself or not.
What I need to know basically after thinking about it with some people at work, is a way to find the acceleration in m/s^2 of each ship (which in theory would be based on the thrust and the mass of the ship, I just don't know the formula). The agility bonus shouldn't be a factor since I'm not taking into consideration the fact you have to align (I'm starting from 0m/s and I'm already aligned), and I don't think there's any drag in EVE's physics so that is not a factor either.
Variables we have in the ship's stats:
- Max velocity in m/s - Mass of the ship
Variables we need to find:
- Thrust - Acceleration - Confirmation of speed to reach before you start warping (2/3 * max velocity or 3/4 * max velocity?)
Those variables are based on real life, so I don't even know if "thrust" is actually a variable in EVE's physics, which is why I would need the DEV's to give me the actual formula used to define how fast a ship is accelerating.
Do I make any sense?

Edited by: Kazuo Ishiguro on 27/11/2006 16:55:33 Thrust is a variable in EVE, but afaik it doesn't directly relate to acceleration- the 'thrust' of an afterburner or mcrowarpdrive divided by total ship mass determines the % efficiency you get from it after all other bonuses have been applied. This figure is not taken into account in the 'max velocity bonus' attribute of such modules, even when they are fitted to an active ship.
Incidentally, ships do have an attribute which is either 'x propulsion strength', where x is one of fusion, ion, magpulse or plasma, and this attribute is larger for larger ship classes. I'm not sure whether or not this is related to propulsion jamming, though, rather than acceleration.
I'm not sure whether increased agility enables a ship to accelerate faster or whether it only reduces the time required to align.
Even without dev co-operation, it should be possible to get some fairly accurate data on acceleration times by using fraps, provided that you can get a good number of frames per second. I'm not in a good position to help with this, as I only get about 10fps when undocked.
In general, bigger and less agile ships seem to take much longer to accelerate, so it'd be best to use battlecruisers or larger to help reduce margins of error. ---------- An idea for helping people to appreciate ECCM |

Ya I know I could do that, but I want the formula itself so I can calculate it by using stats only... guess that's not possible then... I don' thave the luxury of having either the skills or the isk to equip larger ships too...

It wouldn't be expensive or skill-intensive to test this. I would use a Sigil, since they're cheap, slow and have 5 low slots. ---------- An idea for helping people to appreciate ECCM |

Will do as soon as my char on SISI is enabled...

The devs never publish a formula unless the players have found it out by themself already. They may post hints but that's as far as they will go. ---------------------------------------- A Guide to Scan Probing in Revelations |

Well, you always go to warp when you reach 75% of your max speed. So what you really want is the standard Ship Acceleration formula so you can figure out how long it takes your ship to accelerate to 75% speed.
Not that that helps you much, but I'm trying to be helpful -----------------------------------------------
