What are you working on? v16

[Vbitz]

What language was that done in?
And using What?

C# using Winforms.

[QUOTE=Overv;28554347]Do you guys like the concept of making a class with all of an application's functions and variables and creating an instance of that in the entry point function or do you prefer the 'regular' way?[/QUOTE]

Kinda late, but I don't like that way because it makes it seem like you can create multiple instances of your program within a single program, which doesn't make sense. Alternatives are making all the members of the class static, or not using a class and using a namespace instead. I use the namespace way most often.

[robmaister12]

so I opened up my level editor again, trying to add a few more features before calling it done. Realized that most of the level editor was in a single form file, split up into 4 partial classes. I could just rewrite it all in a much more organized way, or I could just tack a few more methods in here and it'll have almost identical functionality...

Too close to release for a rewrite, but at least I know what NOT to do next time... anyways, here's the latest feature, triggers, and I spent a while wrapping my head around UITypeEditor to get that dropdown list to work properly and display the entity list.

(also, I had to align the dropdown manually in photoshop because alt-prntscrn would only take a screenshot of the dropdown and not the entire form, if you're wondering why it's probably off by a pixel or two)

I also implemented exception handling. Totally coincidental. Yeah.

[cpp]
Terrain::Terrain(const std::string& Filename) : m_BlockUVs(0)
{
if(!m_InternalTexture.LoadFromFile(Filename))
throw new std::exception("Failed to load the terrain texture.");

unsigned char Blocks = (m_InternalTexture.GetWidth() / Terrain::BlockSize) * (m_InternalTexture.GetHeight() / Terrain::BlockSize) - 1;
m_BlockUVs = new sf::FloatRect[Blocks];
for(unsigned int i = 0; i < Blocks; ++i)
{
int x = i & (Terrain::BlockSize - 1);
int y = (int)((float)i / Terrain::BlockSize);
x *= Terrain::BlockSize;
y *= Terrain::BlockSize;

m_BlockUVs[i] = m_InternalTexture.GetTexCoords(sf::IntRect(x, y, Terrain::BlockSize, Terrain::BlockSize));
}
}
[/cpp]

* Vomits in mouth.

I really need to clean my code up, on the bright side: I've got Minecraft blocks rendering.

Thats a Sync issue, i forgot to deflate the chunk before resending, you see the corners are water, those got synced correcly, i just fixed it:P

and woa, you realy had to draw a 3d arrow? xD

[~ZOMG]

It's not 3D.

[Asgard]

2D with dropshadow. :v:

[QUOTE=~ZOMG;28560577]It's not 3D.[/QUOTE]
Fine,

Why did you draw a FANCY arrow that has a SHADOW, wasnt just a line whit a arrowhead enough?

[Asgard]

Because you deserve such a fancy arrow?

500.000 and 5fps :O

how do you keep your fps at a good speed jallen? only thing i can think of is limiting the particles

[aero1444]

Trying to make a tile based game (think the way pokemon works when you're not in battle). Got the map loading to work (it loads grids of integers from text files):

MAP LOAD SUCCESSFUL!
00000000000
00001110000
00011111000
00110101100
00111111100
00110001100
00011111000
00001110001
00000000000

Hooray! As usual though, there's probably a million ways I should be doing this that I'm not.
Also I know this is basic but I've been struggling getting this to work for a bit and I'm relieved now - I kept using the opposite values for height and width and it all just became a big mess.

When will you ever need 500,000 particles? I don't think jallen's android app ever has that many (if a. that's what we're talking about and b. it's not changed drastically since the last time I came to the WAYWO)

Got it at least to a working state again:

Well
a. You will never need 500,000 particles.
b. If you ever wanted that many particles, it would be better suited to a GPU to process.

My android one has pretty low caps as the masses massively increase the amount of calculations to be done.

If you think about it, 1000 particles and no masses is just some addition of vectors.
1000 particles and 1 mass is the calculation of the masses effect on each particle, so 1000 grav accel calculations (that includes sqrt for accurate distance measuring)
1000 particles and 20 masses is 20,000 grav accel calcuations.

I have a timestep of 25ms on my app, which means that for 20 masses and 1000 particles it would need to do 800,000 calculations of gravitational acceleration per second.

Double the amount of masses to 40 and you're looking at 1.6 million grav accel calculations per second.
So I capped it.

You either cap it or lose some accuracy of the sim. You could split the area up into a quadtree and calculate the gravitational acceleration for every particle in a given square or something, that may be relatively unnoticeable, I haven't really played around with trying to do any fancy optimisations though.

[Dlaor-guy]

I just noticed how ridiculously simple du/dv mapping is. In fact, I just implemented it in my game. Here's the shader code.
[cpp]uniform sampler2D texture;
uniform sampler2D normalmap;

void main()
{
vec2 pos = gl_TexCoord[0].xy;
vec4 normal = texture2D(normalmap, pos);

pos.x += normal.r - 0.5;
pos.y += normal.g - 0.5;

vec4 tempcol = texture2D(texture, pos);
gl_FragColor = tempcol;
}[/cpp]
That's it! Now you have du/dv mapping! To make your average normal map work for this, simply invert it.

That is one incredibly complex vertex shader, you wouldn't understand it.

Shows file size, image dimensions, format and screen size (of the application) plus zoom works a little better. I think I'll make it work by percents..
