| 00:20 | < Rhamphoryncus> | Bluh. Plenty of pages telling me how to induce seizures in someone with photosensitive epilepsy, nothing specific on how to avoid it (in game design) |

| 03:07 | <~Vornicus> | gnah. I find myself once again befuddled at how I want this thing to work. |
| 03:21 | | Stalker [Z@Nightstar-3602cf5a.cust.comxnet.dk] has joined #code |
| 03:28 | <~Vornicus> | Level's an object. THat much is relatively clear. I can create a level by passing in a file name; this loads the level, creates the surface, figures out what entities there are... |
| 03:29 | <~Vornicus> | Then the entities are objects too. All of these, eventually, are in a render list somewhere but I'm not sure where. Probably in the level object, because that way when the level is unloaded the entities are cleared out too. |
| 03:32 | <~Vornicus> | This means that my event loop, generally, tells the level to render itself. |
| 03:32 | <~Vornicus> | and then the level renders its entities. |
| 03:37 | <~Vornicus> | Okay. THen somewhere in here I need to eventually display two levels at once - either I've done smooth scrolling, or I'm doing edge transitions a la LttP |
| 03:40 | <~Vornicus> | Not sure how that is going to work yet. |
| 03:42 | <&Derakon> | Transitioning between rooms can be done by rendering the current display to a surface, then doing a wipe transition from that surface to the new level. |
| 03:42 | <&Derakon> | Thus you only need one level in memory at a time. |
| 03:42 | <&Derakon> | If you want to do smooth scrolling throughout then you'll need to either make your levels the size of the entire world map or hold multiple levels in memory at once. |
| 03:42 | <&Derakon> | I'd advocate for the former at least to get you started. |
| 03:43 | <&Derakon> | You can spawn monsters on the fly depending on their distance to the player. |
| 03:43 | <~Vornicus> | Acutally i think I see how to do it |
| 03:43 | <~Vornicus> | Sort of. |
| 03:44 | <&Derakon> | Also, if you want a quadtree to hold dynamic objects in, you can use Jetblade's. |
| 03:44 | <~Vornicus> | ooh, quadtree. I need to learn how that actually works. |
| 03:44 | <&Derakon> | http://code.google.com/p/jetblade/source/browse/quadtree.py |
| 03:45 | | * Derakon eyes the top class comment, notes he cannot spell "spatial" consistently, apparently. |
| 03:45 | <&Derakon> | Anyway, let's say our world space is a 256x256-unit square. |
| 03:46 | <&Derakon> | We create a 256x256 quadtree node. |
| 03:46 | <&Derakon> | We spawn an object. We stuff it into that node. |
| 03:46 | <&Derakon> | We spawn another object, we stuff it into that node again. |
| 03:46 | <&Derakon> | This repeats some number of times until we hit the max we like to have in a single node. |
| 03:46 | <&Derakon> | Then we create four 128x128 nodes underneath the 256x256 node, and divvy up our objects amongst them. |
| 03:46 | <&Derakon> | (Objects that straddle the boundaries between two child nodes stay at the top level) |
| 03:47 | <&Derakon> | Now when we add new objects, we push them down as far into the tree as we can. |
| 03:47 | <&Derakon> | When it comes time to do collision detection for a given object, all the candidates we have to consider are either in the candidate's current node, or one of that node's parents. |
| 03:49 | <&Derakon> | Hm, Jetblade's QuadTree creates all children when the initial node is created. Probably inefficient, but oh well. |
| 03:49 | <~Vornicus> | -- or in any of that node's children. |
| 03:49 | <&Derakon> | Yes, quite. |
| 03:49 | <&Derakon> | Well...no, not entirely. |
| 03:49 | <&Derakon> | Any child that the candidate does not intersect can be skipped. |
| 03:50 | <&Derakon> | If we have an object in the top-left of the root node, then there's only one child we have to consider. |
| 03:50 | <~Vornicus> | So if it's only in the right pair, then I don't need to check the left |
| 03:50 | <~Vornicus> | But if it's only in the top left then it'd be down a level anyway |
| 03:50 | <&Derakon> | Only if we're unhappy with how many objects we have in the root node. |
| 03:50 | <&Derakon> | See line 138 for the collision detection function. |
| 03:50 | <~Vornicus> | aha |
| 03:51 | <&Derakon> | It accepts a list of objects that come from our parents and need to be collided with us and our children. |
| 03:51 | <&Derakon> | The first thing we do is prune out objects in colliders that don't actually intersect us. |
| 03:52 | <&Derakon> | Hm, if I wrote these functions today there'd be more comments~ |
| 04:10 | <~Vornicus> | Heh |

| 06:20 | < Eri> | Hmm. So, how can I use the terminal to start a program, but still be able to use the same terminal window afterwards for more commands. |
| 06:21 | < Eri> | Like, if I type, $ ibus-daemon, it starts ibus, but that terminal window is exclusively dedicated to ibus, now. |
| 06:21 | < Eri> | Is there some way to, like, fork the two processes, or something? Like, this is a daemon, it doesn't need my input |
| 06:21 | < Eri> | At least, not from terminal |
| 06:25 | <@Tamber> | "ibus-daemon &" will run it in the background. But it'll still end when you close the terminal. |
| 06:26 | < Eri> | That's fine. Mostly, I just don't want to have a terminal window open for each program. It gets cluttered fast because I always forget where programs are in the menu, so I just go to the terminal |
| 06:26 | <@Anna> | You can also run it, CTRL+Z, "bg" and it'll be fine. |
| 06:27 | | Anna is now known as Ling |
| 06:28 | < Eri> | Hah, that was the worst idea ever. Possibly because ibus kind of hijacks the keyboard input, ctrl+z made everything stop taking keyboard input |
| 06:29 | <@Ling> | Then instead do: screen -Rx ibus ibus-daemon |
| 06:29 | <@Ling> | CTRL+a, d to get back to prompt |
| 06:29 | <@Ling> | Run the command again to get back to ibus |
| 06:30 | <@Ling> | If you have issues, remove the R for the start up, and the ibus-daemon from the recall. |
| 06:30 | <@Ling> | Oh, and -Rs |
| 06:30 | <@Ling> | Not -Rx, sorry |
| 06:32 | < Eri> | Ooh, that's slick |
| 06:33 | < Eri> | I'll have to read more into the man-page on the weekend. This is, like, terminal virtualization, or something? |
| 07:16 | < thalass> | You should also be able to open a new tab within that terminal window, though that's much the same as opening a new window |

| 21:36 | < Tarinaky> | For example, if I have a file containing a list of colours - can I retrieve some builtin that lists all the colours. |

| 21:46 | <@jerith> | in your module. |
