FreeBASIC Community produced game

[dafhi]

Well, I'm starting to glimpse the benefits. Perhaps because Mr. doe's style is more readable than my own. Most importantly, I find myself gravitating towards what i'm seeing as a generalist oop approach. It's not about writing efficient code for size or speed. It's about thinking differently. Maybe not for you guys :P

[BasicCoder2]

To be a "FreeBASIC Community produced game" all those involved have to come to some agreement on how to code together as I assume the original people involved in nano45 must have worked together.

Paul doe wrote: Let's focus on the design aspect of the game for now, shall we? Things such as ideas, concept art, gameplay aspects, that sort of thing. Implementation details will come at a later stage. Agree?

I thought the idea was to enhance the original nano45 idea? The vector nanoShip art is simple enough and wasn't the gameplay to shoot more bullets into the other ship then were being shot into your ship?
One tactic might be for two or more ships cooperate to concentrate all their fire power onto one ship to quickly deplete its "force field" or some other measure of ship viability. Life is about competing. Team members compete for positions within the team but cooperate to compete against other teams. In designing your ship I would say you would need to choose a limited set off features from a set of choices available to all ship designers? Fast but weak. Slow but strong. Weight issues like fuel vs. ammunition. A few powerful missiles vs. a lot of weaker missiles. And so on ...

This is about where I last saw this thread:

My favorite would be "XXX Forgotten Universe Gaiden". The 'Forgotten Universe' part comes from the fact that I missed that thread back in the day, and was a very cool project that was eventually forgotten. And the japanese term 'Gaiden' means literally 'a history within a history' and can be translated as 'alternate universe', much like this project is =D

And if not NanoShips, I have no ideas.

I like your description "XXX Forgotten Universe Gaiden". I feel a connection with "Forgotten". Should nail down a name, it may help the direction. I had thought NanoShips would be a tip of the hat to the original, but this sounds like it's going to become something different, so, OK to let go.

"Bot" stood out to me, as something generically autonomous, and since I would pretty much watch any anime with a robot in it, I like it. I thought "Exo" would be good prefix to "bots" meaning outside of, the bot gets it's AI externally. Turns out it's a terrible name when I search the net if it was in use.)

Anyway, with the japanese motif, "enemy" translates to "Teki", and in english would be a homonym (homophone?) for "Techie" meaning a person who is expert in or enthusiastic about technology, especially computing.

So, how about "Tekibots Forgotten Universe Gaiden"?

I don't know if this would be of any help, but I have spent quite a bit of time developing a physics engine specially for 2D space type games. It has commands for creating planets, asteroid belts and entire solar systems with complex orbits, deriving orbit data from state vectors, drawing orbits on screen, realistic rocket physics and those sort of things. It also has a very robust spring-type constraint for simulating rope, girders, and other rigid structures. I intended to make several different space games with it, but I simply lack the time and - increasingly - the motivation for doing it, since it is a very slow process. I am also developing a game engine that utilizes the physics engine, but it's not as matured. If you are interested I suppose I don't mind posting the source code with a number of test scenarios. Also, being part of a game developing group might be exactly what I need to find my lost enthusiasm :-) Cheers, Mike

[badidea]

I liked the "NanoDrones XXX" suggestion. A drone can be lots of things, e.g. a tank for a future version :-)

I don't know if this would be of any help, but ...

Sounds interesting. No battle tanks in your code I suppose?

No, as mentioned this wold probably only be useful if we stick to the space battle type game.

Nice! I'm agog which else unexcavated treasures will be brought to light here. :-)

[BasicCoder2]

It seems to me that the thread is meandering all over the place but not settling anywhere or any direction?
Looking at the nano45 example it seemed to be the same "physics" as in some Asteroid games with wrap around?
Two steering rockets to rotate the ship and one to increase velocity in direction the ship is pointing and another to decrease the velocity of the ship in the direction it is pointing.
Just the wrap around makes it unrealistic unless the small area of space is curved back on itself somehow.
What would a real space war look like? Not like the dog fights of World War 1 used in the Star Wars films.
Let us say there are two space stations in orbit around a planet. Think about the physics involved if each one could release fighter space ships.

[paul doe]

No, as mentioned this wold probably only be useful if we stick to the space battle type game.

Post it anyway. The bigger the pool of ideas/inspirations/concepts, the better, since we'll have more to draw from.

[paul doe]

It seems to me that the thread is meandering all over the place but not settling anywhere or any direction?

That's why it's called 'branstorming', buddy =D

Looking at the nano45 example it seemed to be the same "physics" as in some Asteroid games with wrap around?...
...Just the wrap around makes it unrealistic unless the small area of space is curved back on itself somehow.

Let me state this again: it does not need to be 'realistic' to be fun. In fact, quite the contrary.

What would a real space war look like? Not like the dog fights of World War 1 used in the Star Wars films.
Let us say there are two space stations in orbit around a planet. Think about the physics involved if each one could release fighter space ships.

It would look boring. There's no laser known to man that works like the ones you see in the movies. There would be no explosions, since there's no air, and there wouldn't be any sound for the same reason. So, the 'realistic' space war would involve things throwing rock pellets at each other and silently imploding out of existence when their hulls got broken. As much fun as it sounds =D

[BasicCoder2]

Let me state this again: it does not need to be 'realistic' to be fun. In fact, quite the contrary.

Yes I get that. I was responding to h4tt3n offer of a real physics engine and how it would be used.

[paul doe]

... but this sounds like it's going to become something different, so, OK to let go.

More like a 'spiritual successor' =D

Anyway, with the japanese motif, "enemy" translates to "Teki", and in english would be a homonym (homophone?) for "Techie" meaning a person who is expert in or enthusiastic about technology, especially computing.

So, how about "Tekibots Forgotten Universe Gaiden"?

I also like anime (good mech animes in particular). So, we're going for the japanese anime aestethic? I think 'TekiBots' sounds silly =D but I have been preparing another proposal that pretty much integrates every idea drafted in the thread (so far at least).

I only need to know if we're going for the anime look, so I can prepare some concept art and start evolving from there. I think that the theme is well suited for anything robot-mech-cyberpunk related stuff (especially if it involves massive shooting), but what do you guys think?

[coderJeff]

I think 'TekiBots' sounds silly =D

Aw, :(, I actually gave that some serious thought, and it's not very common according to google. But no matter.

but what do you guys think?

paul, I think you have direction in mind, and I think you should just go with it. Show us what you've got. I will write an AI or two. :)

[paul doe]

Aw, :(, I actually gave that some serious thought, and it's not very common according to google. But no matter.

I didn't meant to hurt your feelings, sorry ;) Just kidding. I only tought it's a bit anticlicmatic, no?

"TekiBots Hyper Galaxy Meltdown"

Mmmm... XD

paul, I think you have direction in mind, and I think you should just go with it.

I see. But, it seems that it's not what the other members want, so I think I'll follow your suggestion and just go with it on my own. I was thinking of something worthwhile to do in FreeBasic, and you provided a very interesting project to pursuit, indeed. Thank you!

Show us what you've got. I will write an AI or two. :)

In due time. Looking forward to it! =D
