In Topic: Alien Invasion

Plus we would probably have a rather long warning of their approach due to how far out they would most likely begin adjusting their orbit, which would make an ever growing signal for us to detect. As we add more and more to our telescope capacity the odds of detecting them earlier go up, meaning we probably have a year, if not more, before they come within contact range. Assuming we can figure out WHAT it is, that gives us a lot of time to get defensive tools in place.

I feel like this is the point that we start to try to deflect/destroy these rocks before they get to the Earth. It might be a desperate attempt, but it's what we'd end up doing. Plus if someone started lobbing rocks at the Earth, we'd see it coming, and again, unless the aliens are incredibly good at stealth/cloaking, we'd know they are here, so we would have some degree of preparation in place. How one would prepare for rocks slamming into the Earth though....there wouldn't be very many places to hide, would there?
Would some alien race interested in taking (colonizing) the planet want to lob rocks at it in the first place? Wouldn't that possibly endanger the habitability of it? Or am I just inventing that?

I feel like their is a severe over-estimation in what we'd be able to actually see/detect. yes we are getting better at tracking NEO's, but an alien armada is likely to be extremely tiny in comparison to the size of most asteroids. the resolution and amount of data to track such tiny objects is massive, and we're not exactly pouring funding into this topic. hell if they approach from the sun, we'd never even see them coming. just think about the Russian meteor last year that no one even detected was heading for us.

In Topic: I'm Getting Sick of The Same Posts Over and Over

Yesterday, 05:24 PM

I just had a thought: Mentors!
What if older members of the community (Crossbones+) could opt-in to become "Mentors". New members posts would have to be approved by a "mentor", who would have to do a quick review of the new members post before it was made public. The "mentors" would be able to send them a PM answering their question (if it was something like "What programming language should I use"), and the For beginners section wouldn't be flooded with these questions over and over again.

Actually....this idea sounds rather interesting. It'd defiantly help cut down on the amount of redundancy that crops up from most beginners.

However their would have to be some limits, such that only this level of moderation occurs to members that are very new(less than 72 hours would probably be a good barrier). the system should not hide these posts if they are easily solved, but instead auto-post the thread/"mentor" response into a mega sticky thread in the beginner forum so that all of the information can be publicly viewed. and if no one responds to one of these posts within say 4-6 hours(or if a "mentor" says it's OK to post this.) it should be auto-posted. at least this is my opinion of how it could appropriately work.
in short, the mentor has no moderation control over the thread, they simply help facilitate a faster/more appropriate response.

What with the Crossbones+ system being kind of fuzzy (is this still the latest on the matter?) I'd figure maybe something else...

as far as i'm aware this is still the status, but truthfully i suspect if you pm any mod saying you'd like to contribute to the forum by being a cross-bone member, they'd gladly make you into one.


-> it's kind of like moderating, you view it and approve or not for publishing and only moderators see the posts...

-> beginner posts would be more visible for experienced users and less visible to beginners who'd think "nobody seems to ask which language I should use!" since they get moderated out.

I disagree, in no way would it be moderating, in my opinion all the information should still be publicly visible, it'd just be emplacing a potential delay on the poster.


-> the moderators are actually pretty much all the site frequenters (except who don't want to participate) so really it'd be like the beginners were the only people who didn't see it.

I disagree with the idea that the moderators are the only site frequenters. plenty of people lurk this site daily, and many of us sit in chat regularly. 
also, their are a crap ton of moderators whom no longer seem to be apart of this site. just look at the listed moderator for the lounge: http://www.gamedev.net/user/13498-ravuya/ last active over a year ago now.

-> it's like an own subforum for beginner questions that is only visible to experienced users before they're published in the beginner area

a sub-forum might be a decent way for this to work, but in theory all posts should still become publicly visible, it's just this sub-forum would allow filtering redundant/unrealistic posts into a mega-thread that doesn't cause other posts to fall down in visibility because someone once again came in with a "where do i start?" "what language should i use", etc. the beginner forum is practical in terms of beginner level questions, but should it really be flooded with trivial questions that have been asked/answered a billion times. their's a major beginner level difference between a question like "how do i move a paddle in pong?" and "what language should i choose?" both of these questions are beginner level, and yes, both have been answered a bunch of times. but one is a specific problem to programming.

edit: as of this post, there are 6 posts on the first page of for beginners that in my opinion would fall under this mentor system:


In Topic: Quaternion-Rotation to Degree (Edge-jump)

Yesterday, 04:50 PM

You only really need a fairly basic understanding of what a Quaternion is to be able to use them effectively, and for animations, it's totally worthwhile to gain that understanding.

I had my animations implemented using Quaternions at first. 
I am currently rewriting my whole animation code based on a model suggested by L. Spiro, and so far it works out awesome. The last thing I need to get right are the rotations.
Like she mentioned in her post, Quaternions are really slow compared to matrices. And the track based animation system requires me to know every single part of the world matrix in order to gain speed.

so why are you pulling euler angles, instead of rotation matrix's out of the exporter? i'd say keep quaternions as your animation format, and simply convert it the rotation matrix upon loading the animation.

I agree with this. The logistics of interstellar space travel make smaller and lighter more practical. These hypothetical invaders may have quite the arsenal back home, but bringing it with them would prove to be quite difficult. Even advanced technology needs to obey the laws of physics.

I agree with this, as OP states this would be a pre-FTL race, so it's very likely that alot of these rules still apply to them. the exception might be if they've figured out how to effectively create anti-gravity devices(but if this is the case, they would likely be an post-FTL race).

Also, an interesting point is different species will have different bar of entry to interstellar space travel. Imagine a small cold blooded race. Being cold blooded they would not need as much food to survive. Being smaller would make it easier to build a starship to transport them. Just to make things easier for this hypothetical species lets say the planet they live on is tiny with a minimal amount of surface gravity that can still sustain an ecosystem. These species would have a lower bar to space travel.
Compare that to the giant elephant sized warm blooded species that have huge gravity wells to overcome to leave their planet. These species would have to advance their technology further before attempting interstellar travel. So the ability to travel travel to other star systems doesn't tell the whole story about how advanced the species is.

I have to disagree here. yes different environments means different entry level's/tolerency's to their local space. but i believe any race capable of doing an out of their solar system trip would all have to be at some minimum level of infrastructure/technology to perform them that far exceeds our own level.

In Topic: Quaternion-Rotation to Degree (Edge-jump)

Yesterday, 03:44 PM

What exactly should I do to get the degrees?

don't use degrees, and go learn how complex numbers work, then quaternions should make much more sense. and don't let the name scare you, the concepts behind complex numbers is actually very simple if you take the time to understand them.
