Got some basic combat going. Still don't have any text output on the actual screen, but, eh. :effort:

Do a class array with text inside it and just have like Datetime and Text just and do a foreach loop in your draw method and have a dead time or something and just do floating text it's very good

Quick question: How is a table in Lua passed to functions? For example, if I did something like this:

[cpp]
// This would return a new table that would be an instance of Player.
static int NetPlayer(lua_State *Lua)
{
// Allocate memory for a pointer to to object
Player** p = (Player**)lua_newuserdata(Lua, sizeof(Player*));

// Get arguments and create a instance
const char* Name = luaL_checkstring (Lua, 1);
int Level = luaL_checknumber (Lua, 2);
*p = new Player(Name, Level);

// Use global table 'Player' as metatable
lua_getglobal(L, "Player");
lua_setmetatable(L, -2);

return 1;
}

// This would create the metatable Player
static const luaL_Reg LuaPlayer::Functions[] = {
{"new", LuaPlayer::New},
{"getLevel", LuaPlayer::GetLevel},
{NULL, NULL}
};

void LuaPlayer::Register(lua_State *Lua)
{
luaL_register(Lua, "Player", LuaPlayer::Functions);
lua_pushvalue(Lua,-1);
lua_setfield(Lua, -2, "__index");
}
[/cpp]

[lua]
-- Create a new player named Bob @ level 10
local bob = Player:new("Bob", 10);
print("Bob is level: " .. bob:getLevel())
[/lua]

Would the C function LuaPlayer::getLevel have the table 'bob' passed as the first argument?

I'm currently working on the Matrix4 class of my OpenGL wrapper and I'm wondering if I should make it use column-major or row-major order. Of course OpenGL expects column-major order, but on the other hand it feels hacky to force the class to use column-major order too.

[b]Class uses column-major order[/b]
[list][*]Programmer can pass the internal float* array to OpenGL directly
[*]Difficult to program, as the order is non-standard in C++[/list]

[b]Class uses row-major order[/b]
[list][*]Code makes more sense, e.g.
[cpp]float identity[] = { 1, 0, 0, 0,
0, 1, 0, 0,
0, 0, 1, 0,
0, 0, 0, 1 );[/cpp]
[*]Matrix requires transposing to be loaded in OpenGL[/list]

No. Render the text to a render target and as the text is updated re-render to the render target. Use something like std::list<std::string> and pop text off the front when you are done with it.

[QUOTE=DevBug;28150781]Would the C function LuaPlayer::getLevel have the table 'bob' passed as the first argument?[/QUOTE]

These two lines are equivalent:

[lua]bob.getLevel( bob )
bob:getLevel()[/lua]

[QUOTE=Overv;28150887]These two lines are equivalent:

[lua]bob.getLevel( bob )

Thanks.

i just replaced 215 lines of non working code that took me 2 days to write, with 15 lines of working code that took me 10 minutes to write

Fuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu-

This is for a physics engine by the way

Working on a water fog shader.
The water gets more murky the deeper it is and it gets less murky if you are closer to the surface.

I also managed to transform the water shader into a plastic blow-up tent shader.

What are you doing this in OpengL or DirectX?
Also is this for a school/uni thing or are you using tutorials?
If you're using tutorials could you link please?

Stuff like this should probably go in the WDYNHW thread.

is it possible to write the direct content of a pointer (\nd thus a memory address) to a file?
And then later on read that file and write it to memory just like it was before?

This'll do, I think. I think the font fits the game really well. y/n?

I'm going to assume you meant to quote Sakarias88 and misclicked or something because that stuff is a lot more impressive. :v:

Edit: Wait, are you agreeing that the font fits well or because I'm not amazing? :saddowns:

[QUOTE=likesoursugar;28151657]That's the way opengl manage matrices but it's totally up to you.[/QUOTE]

I'm pretty sure that's not how OpenGL manages matrices. ([url]http://en.wikipedia.org/wiki/Row-major_order[/url])

I got pissed off writing a font renderer in D so I've gone back to my original codebase :v:

Need to fix up the lighting because it's pretty slow at the moment. Then I'll move on to fixing the networking and then start embedding lua so I can get some gameplay going.

woops you're right.
[url]http://www.opengl.org/sdk/docs/man/xhtml/glMultMatrix.xml[/url] - deprecated but still the right order.

If the current matrix is C and the coordinates to be transformed are v = v &#8289; 0 v &#8289; 1 v &#8289; 2 v &#8289; 3 , then the current transformation is C × v , or

c &#8289; 0 c &#8289; 4 c &#8289; 8 c &#8289; 12 c &#8289; 1 c &#8289; 5 c &#8289; 9 c &#8289; 13 c &#8289; 2 c &#8289; 6 c &#8289; 10 c &#8289; 14 c &#8289; 3 c &#8289; 7 c &#8289; 11 c &#8289; 15 × v &#8289; 0 v &#8289; 1 v &#8289; 2 v &#8289; 3

Yeah a long while ago. I gave up on the engine because I was having performance issues that I thought were related to the garbage collector.. but it turns out it was just my computer. It runs fine now I've fixed it. A huge waste of time all round.

I have however since then taken the liberty of stealing the tiles from space station 13 :v:

The lights are inside the walls. I currently have the positions hard coded but I changed the map. Causes weird glitches like that. I'm waiting on my friend to send me his RIFF library so I can compile it and change that :p

The content, yes. However you can't guarantee the same memory address when restoring it. And apparently weird stuff can happen if you just move memory around to create a non-POD type instead of using the appropriate constructor or operator.
Can't tell you specifics, though I remember Chandler saying that for classes with vtables that table could be destroyed.

Did you do the right Meter/Pixel Conversion. Also in Farseer the Position is the center of the shape.

Column major. You can easily switch to thinking in column major, too - it's all just conventions.

yea it doesnt have to be the same memory address.
Its just to do some testing about making image files and other file types harder to view by others
