What are you working on? v67 - March 2017

[Ziks]

Going to try making a browser CS:GO surf / kz run replay viewer based on my map viewer, as a quick hobby project.

Here's a demo of a kz map export: [url]https://metapyziks.github.io/GOKZReplayViewer/maps/kz_reach_v2/[/url]

This one doesn't properly stop propagation of keyboard events either :s:

[Cold]

I actually did a BHOP replay renderer based on the tf2 map renderer somebody made ages ago (which doesn't support half the shit you do)

I went a bit over-the-top trying to support way to many custom maps and stranded the project there.

Looks Great

Should be fixed now, you might need to clear your cache.

It works perfectly now, thanks!

I was about to suggest Gmod-like up/down movement, but considering [I]Ctrl+W[/I] closes the tab and seemingly can't be stopped, that seems like a bad idea.
Minecraft's flying controls ([I]shift[/I] instead of [I]ctrl[/I] to move downwards) may work, if you don't need a sprint button. Otherwise I'd try [I]caps-lock[/I] if possible.

Some magnificent bastard at work. I checked and the length of the string is actually 1987.

We have a bit of a tradition of using this song as test data for our RTL designs, it's pretty noticeable in a memory window. Nothing like getting rickrolled by a piece of hardware in simulation.

Y'all know PHP right? And you also probably know Lua. Well, have you ever thought about combining the two into a web-oriented language? No, because no one in the right mind would. Luckily I'm not in the right mind.

[IMG]https://image.prntscr.com/image/3oireypQRQW44fH6LXEHzQ.png[/IMG]

I present to you, lua for web - "why would you do this" edition.

In all seriousness, it currently outputs HTML to a static output file, and am currently working on a fast cgi implementation.

[WTF Nuke]

There's this tiny little function in the standard library added in C++14 that is super useful in some cases. You wouldn't ever want it to happen outside of programming, but std::exchange is useful for implementing move operators. You can this: resource = std::exchange(other.resource, nullptr); which will do resource = other.resource and other.resource = std::move(nullptr).

[roekelt]

Spent some time refactoring LuaForWeb to also allow for third party plugins to be loaded, in this screenshot you can see a simple function that writes to the output buffer (which writes text to the respective location the script is being executed on). I'm currently also perfecting the library system, but that will take some more tweaks before it's ready.

[IMG]https://image.prntscr.com/image/4jKqhVZmQgWAVBISydMgiA.png[/IMG]

As you can see there's an entire Sdk library available so you can implement really anything you want (that doesn't mean you should...) ranging from a simple plugin, to your own executable to process LuaForWeb files.

stopped working on it because i realised i disliked lua
and also i lost the project files ¯\_(ツ)_/¯

Amazing! How are you marshaling the arguments from lua to C# functions (and back)?

I have something that does it transparently here, you can recycle the whole repo if you want. [url]https://github.com/cartman300/Lua.NET[/url]

Did some more work on the replay viewer demo:

What SVN client do you guys use? Looking for something less intrusive than Tortoise.

Framerate seems almost directly tied to window size; get ~7FPS on fullscreen on chrome (1920x1080), jumping to 20FPS on half size. Could be chrome's renderer?

Works fine on my version of chrome : Versie 61.0.3163.100 (Officiële build) (64-bits)

59-60 FPS constantly.

package IO

import org.khronos.webgl.DataView

class Reader(val view: DataView,
             val decoder: Decoder,
             val littleEndian: Boolean,
             var position: Int = 0) {
    fun string(bytes: Int): String {
        val code = ByteArray(bytes)
        for (i in 0..(bytes - 1))
            code[i] = u8()
        return decoder.toString(code)
    }

    fun i8() = view::getInt8 sized 1

    fun u8() = view::getUint8 sized 1
    fun u16() = view::getUint16 sized 2
    fun u32() = view::getUint32 sized 4

    fun f32() = view::getFloat32 sized 4

    private infix fun <TResult> ((Int) -> TResult).sized(byteCount: Int)
            = this(position) before { position += byteCount }

    private infix fun <TResult> ((Int, Boolean) -> TResult).sized(byteCount: Int)
            = this(position, littleEndian) before { position += byteCount }

    private inline infix fun <TResult> TResult.before(after: () -> Unit): TResult {
        after()
        return this
    }
}

I'm not sure this is the intended use of infix functions, but it's pretty useful :chem101:

The only people I've ever seen use SVN are students still in the discovery process and students who think git is "too complicated".

For game development it makes sense to use Git over something like SVN. The newest "Large File Storage" support in Git makes the old issues go away.

I've heard great things about git-svn.

On that note, importing RCS repositories to Git is not fun, and people who still use RCS today should go rethink [i]every single on of[/i] their life decisions.

SourceTree is far better than Github GUI IMO.

[QUOTE='[aL`H]solokiller`og;52837479']SourceTree is far better than Github GUI IMO.[/QUOTE]

I like sourcetree, but I've started using gitkraken. at first I didn't like how it really pushed the "modern" aesthetic and it seemed to almost obfuscate functionality, but gitkraken handles stashes better, auto-fetches from the remote much more frequently, and has handled larger repositories better. I've also found its conflict-resolution tools to be much better than sourcetree's.

Also, sourcetree has been super buggy and crashy for me as of late.

also, things like this are why I'm pretty sure I'll never truly know C++ in full. I constantly discover new things, like this.

[editline]30th October 2017[/editline]

godbolt is like a drug, I get on it at work to see how changing a few things in a method affects what it compiles down to and suddenly i've burnt two hours looking at assembly

its probably not all bad, though. i never got the chance to take a course vaguely covering assembly and how to read it, and i've already learnt a few things about assembly easily along with learning a few small techniques to improve my code. like how std::transform almost always optimizes really, really well!
