DEM ISLANDS AND DAT OCEAN

Spent half my programming time trying to fix why coasts wern't working and then suddenly they do FML
Next to fuck with the generator to stop the islands from being so square and make the ocean more... ocean-y

I've been having fun with vectors:

[img]http://anyhub.net/file/21Ak-raycast.png[/img]

Pretty much every problem I've had with it is because I've used angles to find out what is in the beam. Going to work on a way of doing it without angles now.

Added a "Debug" menu; currently implemented is a listview showing the output of the tokenizer - helps to make sense of errors, seeing as I give error positions in terms of token indexes :v: I've also changed the differential syntax, and I think it's a lot better now: "d/d" is the differential operator, which takes an ID and an expression as its right operands. The operator is only recognised if the first "d" is a distinct ID, so "bad/d" still tokenizes to "bad divided by d". Hopefully no one who uses it will need to find the value of d divided by d.

Not a progress update, just thought this was kinda neat - plotting Taylor approximations to the sine function, of varying degrees:

This is starting to turn into something I might actually use because of what it does, not just because I made it :v:

[QUOTE=Yogurt;33922679]Damn, that doesn't work that well? That's how I thought of solving that too.[/QUOTE]

The problems are mainly around the -180 -> 180 wraparound (well -pi -> pi). It's possible if you keep that in mind, but I feel dirty after using vectors for everything else and resorting to angles for that.

[Jookia]

Today I got Valgrind memory checking for my game working. Ignoring leaks from my video card drivers, X11 and Boost all really tick me off, but I can't fix it from my application, so it's not worth my time. Maybe tomorrow I'll figure out unit tests.

Well, time to hit the hay (maybe cry over lost love too) after doing that.

Recently entered my second Ludum Dare with a friend, did a few things I've never done before within that, and came out of it with fresh motivation to improve and expand, so I decided to move into tile-based games (at last).

I originally worked out and implemented a simple tile-based system by myself, which included random map generation (with no pattern or smart generation algorithm) containing two different kinds of tiles, and a player entity with half-working collision on one kind of tile. Here's a video of that attempt:
[video=youtube;uuoDENyGvXs]http://www.youtube.com/watch?v=uuoDENyGvXs[/video]

I then saw the work that reevezy67 was doing on his new tile-based platformer and asked him for a bit of advice, and have spent the latter part of today working on this:
[video=youtube;5cvhpwcQokM]http://www.youtube.com/watch?v=5cvhpwcQokM[/video]

Next up for the platformer is a map editor of some kind, scrolling maps, and proper collision detection. Things're going well!

[r0b0tsquid]

Variable watch window and procedure list are good to go. They're all mapped to F keys, so you just hit a key and they pop up - it's pretty handy :)
[img]http://i.imgur.com/49qBl.png[/img]
Did I mention they all update in real time? :v:
Also, while fiddling:
[img]http://i.imgur.com/PM02k.png[/img]
Smoothing doesn't work so well because of the square steps, and the quality's a little low really, but that can be turned up in settings. I feel like I should add intensity / field plots, but that would only really work if I had access to alpha, which apparently wasn't in particularly common use back on 1998 :/

[editline]27th December 2011[/editline]

and I don't see raii or any of that crap in the code i was originally replying to:[/QUOTE]

To be fair, whilst RAII is pretty essential when using like exceptions etc in C++ generally if you don't use them you don't need it with careful planning. It's way more memory leak prone not using RAII though.

I just flat out avoid exceptions in C++ though, I just find they're not needed

There is a lot of things wrong with the code I gave you that I would change now, I basically planned to go through and figure out how it was going to work without worrying about keeping the code clean and then rewrite it.

[editline]28th December 2011[/editline]

Mainly being the compensation for velocity in the collision detection isn't all that great.

Some kongregate user just PM'd me and asked me how to upload a game. I asked him what type and he said "I don't know, I didn't make it"

You should probably link graphics and window too

[r0b0tsquid]

Squashed some bugs, added a few functions that I felt it was lacking - on the language-y side, there's now an input() function that gets user input from the user, and I've added two different random functions - one of which returns completely pseudorandom values, and another of which is deterministic based on its input.
I can feel my productivity declining as this gets more fun to play with - here's a simple 1d perlin noise / terrain function I knocked together in a few minutes:
[img]http://i.imgur.com/10mpe.png[/img]
This would be pretty easy to extend to 2d, but I think I've been diverted enough :v: at the minute I'm pondering how I might do arrays, I think I'll sleep on it.
