Player Features and Ideas Discussion

So my idea is quite simple.
Much bigger ship cannot be bumped by much smaller one , if a small one tries to do that it will simply be bumped away like from a stationary object ( for example stationary station ).
For example.
- You cannot bump a titan/mothership with something smaller than capital.
- Capital can be bumped only by a Battleship or bigger size ship.
- Battleship can be bumped by a Cruser or bigger class of ship
- etc
As simple as it is - this will solve some issues - and be obvious.
Now you can bump a titan with a noobship.

No additional calculations - if you use smaller ship - it simply cannot do this.

Collision plus inertia would suggest the smaller object would be affected to a degree equal to it's momentum as applied to the inertial resistance of the larger object.

An object with twice the mass and inertial resistance would move half as much due to the collision, the remaining force being rebounded back into the smaller vessel.

Against an object with exponentially higher inertial resistance, the smaller craft would bounce like a ping pong ball against a wall, and for much the same reason. (Frigate vs freighter collision)

The wall would be affected, but at such a trivial amount that it would be meaningless.

Of course, you could always use the damage model instead of the bouncy one... the small ship would penetrate the larger one, with physical penetration and compression dictated by relative density of the two objects at the points involved.

Like a bullet.

Fire a micrometeorite into a satellite, what happens?

Fire a 747 into...well. You can see where this is going, right?

Think of it like this. The bump mechanic is a safety feature built into every ship. If I fly my jaguar into your erebus ( ), then both ships move away to prevent the destruction of one and the damage to the other. Without it, I could ram empire people, and either die and get them concorded, or just kill them without needing to bother with things like 'fitting' or 'skills'.

The energy to move the freighter comes from the freighter's engines.

I would love to see an inertia anchoring module
While in effect you have effectively webbed you self at 90% and hit yourself with a Perma point.

This way while active you won't be fleet warped off,
It can't be used to insta warp your self off
If bumpped and the equation on Bumper weight x speed/ Bumpy weight = Bumpy speed would be cut down to 10%

If left on auto pilot to keep at range, the ship would limp ack to position at 10% speed

Would be a fan of those Titan pilots, rorqual pilots in a pos
Not sure if this would effect the mining bumping issue


Though I think the calculation of bumping changing the direction of a ship... May be off, gut feeling.

Also it would be a blast it there was an option or a modular that would turn your shield "Aggress" so while active bumping you would cause and take damage depending on inertia equations.
(Titan could just physically mow through a fleet )
Site of a thousand newb ships suiciding against a titans shield.
If active in empire unless your target is a war target, you would get your self concorded if you tried this

We entered arbitrary gameplay mode when we agreed bullets, lasers, and missiles would inflict damage, however projectiles that were ship sized would harmlessly bounce off.

Forgive my lengthy response, I am an engineer and for me this is good fun to talk about.

(Might wanna copy and paste, the forum is muddling the link when I try it from here)

Friction is not a simple force. It specifically refers to contact with a medium that possesses volume and mass, but contact is only partial in nature for whatever reason. Therefore you only interact with a fraction of the whole.
IE: You are passing through a gas or liquid, you are making contact in a manner that does not reflect as a collision against the complete object, just the section in direct contact.

An object in motion tends to stay in motion. An object at rest is an illusion, it simply is in motion identical to it's surroundings and is not moving relative to them.
(Think of two cars going down the highway, keeping pace with each other. From the perspective of each car, the other is not moving. The other details are obvious to anyone familiar with cars driving)

The inertia of an object is specific, and requires an amount of energy to offset this value and put it in motion.
If you take a freighter and hit it with a frigate, a cruiser, or a battleship, there will be a transfer of energy.
But to the point of impact, (for perspective to help understand), treat both objects as approaching each other at an equal speed determined by each having half the speed of the moving object.
(Instead of a frigate moving at 5k m/s, both freighter and frigate move towards each other at 2.5k m/s)
The bounce or collision is identical in either case, this simply helps many understand better what is happening.

(The universe has no non moving objects we can use to measure by. To our awareness, all things are in motion, so we just orient on the biggest object we can find for reference. That's usually the Earth)

The larger object, in this case, will not be changing direction. It's mass's inertia was not overcome by the smaller object. It will be slowed down by an amount determined by the combined inertial mass of the smaller object.
Keep in mind, unless the frigate has a glove effect, it's engines would need to be on par with the freighter's to move it significantly.
This game also imposes an arbitrary speed limit on ships, as if they had to overcome atmospheric friction or something equivalent. You can stop by just cutting your engines, rather than needing to accelerate them in the opposite direction.

By glove effect, I mean the frigate has mass, inertia, or power to increase either, that exceeds the ship's expectations. The freighter must be missing this aspect to avoid it cancelling out.

You need to take physics 101 for the FIRST time!

Friction has nothing to do with why a tank does not move when it is shot with a bullet. The reason it does not move is because the mass is so much more... it DOES move but it moves so little it is not noticable. Similarly if a person is shot by a bullet, they do not go flying back like they do in the movies... even if they were standing on a frictionless floor they would not be pushed back by a bullet, the bullet would kill them but they would just fall down dead.

If you don't want to do physics 101 then this has been done on Mythbusters many times before. I suggest the episode where they try to make a carousel spin by shooting it. Even by giving it a virtually frictionless bearing and using the biggest bullet they have, they are only able to make it move very slightly. Why is that? Friction? No, it's because the bullet, even though it is moving very fast, does not have enough kinetic energy to make the carousel actually move.

Momentum is conserved, but there is a lot of KE left unaccounted for in EvE collisions.

They should do something with that leftover KE.

FYI, I teach Physics 101...



and in space... once it started to move it would continue moving.... On Earth, the force of the collision is NOT large enough to overcome the force of friction so it won't actually move... (unless you consider rotational motion resulting from the point of momentum transferred, but we'll leave that alone for the moment). Granted, even in space a tank would only receive a very small increase in speed do to the mass differences between the bullet and the tank... and we both agree on that...

Also,
A bullet 10 g. Tank 60,000,000 g. The ratio is on the order of 10**-7. A bullets velocity.... 300 m/s

A frigate 1m kg. Titan 2.5b kg. The ratio is on the order of 10**-4. A frigates velocity.... 5000 m/s

These are not equivalent comparisons...

In all seriousness, if realistic problems are pointed out, realistic solutions will be suggested.

This fellow has it about right. Look at any airport as an example of how collisions are avoided. Strict regulation of incoming and outgoing traffic occurs.

We only have this overlapping effect because it is not an issue. Gameplay is not advanced here by making it one, in this specific.
