| Topic | Who would you say "won" this hypothetical argument |
| Sahuagin 10/07/18 12:24:13 AM #10 | argonautweakend posted... Person A states their belief. Person B enters and states why they feel A's opinion is wrong. Person A misinterprets B's argument and argues from that position. Person B restates their argument for clarity. Person A, again, misinterprets B's argument and argues from that position. Person B says they are done with the argument as a result and walks away. inconclusive. we have no way of assessing which arguments are valid. for all we know Person A might be misinterpreting a valid argument, when Person B's rebuttal is actually invalid. --- |

| Sahuagin 10/05/18 11:25:01 AM #22 | checking some of my code, one place I use ref is on string validation the bool return value indicates whether the string changed, and the string changes to a different string if it was "messy" (whatever that means in the context of the method) Magus 10 posted... Yeah, multiple returns is the scenario I was thinking about with tuples being another option, although I suppose in the case where you're checking an error return value then out params are probably a little easier to use. another scenario is method chaining. if you want to return values while method chaining you have to use out parameters. I have a tree control where I build the parts of the tree in a method chain: It's maybe a bit overkill, but I just wrote a method that allows me specifically to assign in a method chain, which allows me to avoid a starting variable at the top. turns this: to this: it's not a huge difference, but it reads a lot nicer since the assignment is now where the actual value is instead of at the opposite end also with TryParse, I actually clean it up so that I can write this: if (someText.IsNot<int>(out var intValue))--- |

| Sahuagin 10/05/18 2:22:33 AM #20 | Magus 10 posted... You should never use ref unless you have a very good reason why (which 90% of the time is PInvoke, and the other 10% can probably be done a better way with tuples or something; edit: actually that's more likely the solution for out params, but I can't think of anything else for the other 10%). one use for ref would be maybe if you had a counter that you wanted to pass between methods. then you can share the counter between a bunch of methods and increment it in any one of them. but then you can just put it in an object, too, which is better, so it's not super useful. there are definitely some good uses for out parameters though, especially now that they aren't so clumsy in C# 7 with out var. the standard example is something like: --- |

| Sahuagin 10/05/18 2:09:23 AM #19 | Yellow posted... Well, the idea is that it would take an existing object and turn it into a class, I don't see the point in passing the type independently when I can pass the type and the object at once. right k, in that case you could just call .GetType() on the object. generic methods are definitely useful, but generics are a complexity that is often better removed when possible. basically you would make it generic if you needed it to be strongly typed, so if there was a return value or property somewhere that you wanted to be type T so that outside users would get back the type they're working with and not something like object. a lot of the time too, you might have an overload that is generic on T, but then just passes typeof(T) to the real method that works on the Type object. the generic overload can be easier to use if the external context has a type parameter, and then the caller doesn't have to manually type typeof(T). (I very often end up doing things this last way. the problem is that you can get a Type object from a generic T very easily, but if in the context you're working in you don't have a generic T, and you just have a Type object, you can't turn it into a generic T without some reflection. so usually the method that does all the work takes a Type object, and the generic method is just for convenience.) Yellow posted... I feel like half the time in C# I don't need to use ref as intended, since most objects just pass references anyway. everything is passed by value, including object references. think of the ref keyword as meaning "in/out". regular parameter: the value passed is received by the method. if the method changes the value of the parameter, nothing is changed "outside" of the method (the original variable that the value came from is not changed). out parameter: you can't even pass in a value, you can only (and must) assign a value to the parameter within the method which then comes out of the method into a target variable. (new in C# 7 you can now use out var to create a variable inline, rather than define a variable on a separate line.) ref parameter: you can pass in a value, *and* the parameter is linked to what was passed in such that if you modify the parameter, you modify the external variable. (the value of the variable, not the underlying object. so a ref list parameter means that you could pass back a different list than the one that was passed in (or you could pass back null). you don't need ref in order to manipulate the list, that already happens just by having a reference to the list). in parameter (new in C# 7): you can pass in a value, but the method cannot change the parameter. basically a readonly parameter. --- |

| Sahuagin 10/04/18 11:03:29 PM #12 | not sure what I should say. some random tips: - look up StringBuilder - your function doesn't need to be generic, you could just pass a Type as a parameter - consider making it an instance of a class rather than a static class, and then push some data up into fields rather than passing arguments - you don't need to use ref parameters, that's just if you would want to send a value back up from the function into the variable - not that important, but should use C# names instead of .NET names for things like string VS String --- |

If it has a very high chance of giving you cancer or makes your lungs unable to push air back out until you become barrel chested and cant breathe, dying of suffocation, then its an unsafe substance unhealthy, not unsafe. unsafe is like dangerous, like something that will injure or kill you right away. unhealthy is like, well you're already dying a slow death *right now* just being mortal. doing things that are unhealthy just means you're very likely needlessly accelerating your slow death. healthy is just the slowest possible rate at which you can die.

While they did study and got better they where apparently prodigies that were naturally gifted and didnt need to be taught to use it, just to get better at it I don't know the black waltzes Porom and Palom have specifically been studying magic since being children. they are naturally talented, but they still learn and are still only performing magic through knowledge and skill. the difference is something like, do I throw a fireball because for some reason that I'm not aware of I can just generate fireballs with my hands (magical being), or do I throw a fireball because I know that fire energy is channeled via the blah blah and moving my arms this way forms a conduit blah blah, and thus I get a fireball. --- |

| Sahuagin 09/30/18 1:32:13 AM #21 | mooreandrew58 posted... Its like that sometimes though. In some lores some mages are just natural and didn't do jack to earn it I feel like I wouldn't call that a mage then. For Kefka and FF6 in general, it's kind of weird because... to me, a mage or a wizard is someone who has spent enormous amounts of time studying and learning and practicing and has knowledge and skill that are theoretically available to anyone, but they alone have earned the ability. but I guess that's a needlessly strict definition that I just prefer. I know in D&D, sorcerers are supposed to have innate abilities, whereas wizards have worked hard for their skills. I guess I prefer it to be about knowledge and skill. if you can just wave your hands and control magical energy innately, then you're just a magical being, not a practitioner of magic. --- |

I love pineapple by itself. fresh pineapple is amazing. also, I can kind of appreciate the taste of pineapple + ham + mozarella cheese. but when it comes right down to it, I enjoy pizza a heckuva lot better if the pineapple is just removed altogether. pineapple is just basically counter to how "normal" pizza tastes. it's the clash of tastes that I think people don't like, not the fact that they don't like pineapple itself. --- |

(and it would not be holographic to the external viewer?) --- |
| Topic | Hey programming people; is it possible to render a hologram onto a texture? |
| Sahuagin 09/27/18 11:16:12 PM #8 | Lokarin posted... Consider reflections in games. The easiest way to do them is to clone the terrain and flip it on the other side of the mirror.... very VERY few (virtually none) do reflections via radiosity. when you say "radiosity" are you using that term to mean something specific or you're just using words that sound vaguely like what you're trying to describe? "cloning the terrain" doesn't really sound like the right way to describe a reflection effect (it's close I guess). I haven't implemented a reflection before but it would I think use the same geometry with some kind of geometrical transformation applied, so that you'd see the same thing from a different angle, and then it would be rendered to a sub-region of the screen. it sounds like maybe you're asking for real-time ray tracing? at some point it starts to be "six of one, half dozen of the other". 3d rendering works by (very roughly speaking) transforming models and drawing them on to a 2d surface, keeping track of whether the pixels being drawn should or should not be drawn on top of the previous pixels (z-buffering). ray-tracing sort of works in reverse: for each pixel in the resulting image, figure out what color it should be by following the path a light ray would have taken to get there, keeping track of everything that was hit along the way, and using various math formulas to compute how they should affect the color. if a ray cast from the pixel immediately hits a red object, then it should be red. if it goes off into space, then it should be the background. etc. ray tracing is traditionally very slow, though if you google it you can find some modern examples of real-time ray tracing:  I guess basically you need to be more specific --- |

| Topic | Hey programming people; is it possible to render a hologram onto a texture? |
| Sahuagin 09/27/18 9:32:06 PM #6 | what exactly is the effect? reading about it it just sounds like it's a 3D image recorded onto a 2D surface (ie: in such a way that it changes depending on perspective). so yeah, a mirror in a game, or even just 3D graphics as a whole, which generate 2D representations of 3D models. it's more like that 3D graphics are already doing what holograms are doing so much better that you don't even notice. Lokarin posted... EDIT: And I do mean by using the same technique as real holograms... not just using a 3d cubemap with a 3d model in it that's like saying "using the same technique as real photographs, not just using a 2d image". are you looking for a full light-ray simulation or something? you could maybe do holographic ray-tracing, where you generate ray-tracing results from multiple perspectives. the result would have to be a gif or like one of those 360 degree videos or something. thinking about it, maybe you mean that the result is literally 3D to the viewer? so moving the viewer's head changes what the image in front of him looks like? I've seen that done before with motion controls, so that the game knows where the viewer's head is:  --- |

| Topic | How do you feel about multiple ending horror games where every ending is bad? |
| Sahuagin 09/26/18 2:00:23 AM #21 | Revelation34 posted... You could use that logic on any choice based game. sort of yeah. the same problem exists in any situation with choice: given two options A and B, it wouldn't make sense to make A a choice with a good outcome, and B a choice with a bad outcome, unless it's a riddle or something. (or even like that there are clues that B would be a stupid thing to do and A a smart thing to do; in that case you're rewarding the player for paying attention, though it could hurt replay value once you just know 'always A'). rather, to avoid that issue, the outcomes shouldn't be black and white, but complementary shades of gray (or maybe starkly contrasted outcomes but for role-playing purposes where you could have obviously good choice and obviously evil choice, or choice that benefits either faction A or B, etc.). but for the horror game thing... the existence (or lack) of a good ending seems pretty significant, regardless of all of the above (depending precisely what 'good ending' means). it's a pretty big thematic difference. almost changes the genre if you overdid a good ending. if everyone CAN get out alive, then that's what you aim for, and anything less is some kind of loss. that's changing the genre of the game, or something. on the other hand, something seems off if we say "horror must always have a bad ending", too. --- |
