What Do You Need Help With? V6

[Lemmingz95]

Well the semi-circle your describing (-90 -> 90) contains 180 degrees (or PI radians - use radians)

The used hours as a percentage of max hours is just used/max ... So multiply that by PI and you get your angle.

Ok that helps me a little i understand what do you mean i and tried but i do it wrong.

120/150 = 0,8

0,8*pi = 2,51

Or does Multiply mean 0,8*pi² ?

[Tamschi]

That result is correct, you just need to subtract pi/2 (quarter circle) to get it to the -pi/2 - pi/2 range you need.

Unless, of course, you can't output radians, in which case you need to use 180 in place of pi everywhere.
(Pi is only a half circle in radians, which is really annoying when working with it [URL="http://www.youtube.com/watch?v=FtxmFlMLYRI"]so there's an alternative[/URL].)

Okey, i found out my own solution and it it right to.

here my example

MaxHour=150
UsedHour=120

Prozent=120/150*100 = 80%

angle=(180* (80/100))-90 = 54

so angle is 54°

hope i typed it right

I hope you're using floating point numbers...

Replace 100 with 100% (=1) everywhere, what you're doing now is a really roundabout way of getting the right value.

I'm pretty lost on how to construct a JSONObject in the way I want (Android/Java). My google skills don't seem to be enough.

This is essentially how I want it to look like, with the possibility of multiple answers for the same form.

JSONObject = {
  "username": "John",
  "Organization": "dummy",
  "completed form number 1": [
    {
      "answer": [
        { "name": "One", "score": 90 },
        { "name": "Two", "score": 96 }
      ] 
    },
    {
      "answer": [
        { "name": "One", "score": 79 },
        { "name": "Two", "score": 84 }
      ] 
    },
    {
      "answer": [
        { "name": "One", "score": 97 },
        { "name": "Two", "score": 93 }
      ] 
    }
  ]
  "completed form number 2": [
    {
      "answer": [
        { "name": "One", "score": 90 },
        { "name": "Two", "score": 96 }
      ] 
    },
    {
      "answer": [
        { "name": "One", "score": 90 },
        { "name": "Two", "score": 96 }
      ] 
    }
  ]
}

I have no idea on how to make sure the structure is correct when coding from Java/Android. I'm currently using a simple

List<NameValuePair> params = new ArrayList<NameValuePair>();        
params.add(new BasicNameValuePair("tag", tag));
params.add(new BasicNameValuePair("username", username));
JSONObject json = jsonParser.getJSONFromUrl(URL, params);

for my other purposes, but I don't see how that would work with what I want to do without sending answers separate which is really redundant.

Is it possible to add a HashMap<String,String> to the jsonobject, or is there a specific way I should use to construct my JSONObject with several objects?

Can anyone tell me why Java is such a fucktard?

scanner.nextLine() is meant to throw a NoSuchElementException if nothing is in the buffer, yet when connected to a sockets InputStream it just hangs and waits for more data to enter the buffer... WHUT?

The default streams in every language do this, they always block if the source wasn't closed.

I think in C# you can check whether data is available through a property, Java should have something similar.

Alternative: Start a new thread for the read and kill it after a second :v:

How do you guys manage to get two libraries working together nicely when they use different Vector classes?

I have my main program (lets just call it main), then I'm using a library that references and uses the Vector3 from the SharpDX library.
Also I have another library that uses its own Vector3 class.

I dont want to include the whole SharpDX library just because of its vector class and I can't change and recompile it.
I just want one single Vector3 struct/class that I can use troughout the whole VisualStudio-Solution.

Is there a way to do this? I already tried to unsafe-cast the different vectors and it works. But this still doesn't get rid of the SharpDX library...

Hi there, I'm just wondering if anyone can tell me how to implement a void function held in another file, for example, "foo.cpp" - obviously being defined through "foo.h" - using Windows API?

By this I mean the function must output to the interface and not to the Command Prompt.

I presume you must implement it through WndProc function? In a WM_CREATE case?

I'm trying to create a radial menu program for windows in C#.. I think I can manage everything except I can't figure out how to block the default right click menu from showing up... I don't really want to straight block the raw mouse input events because that seems... bad... but I would like to block the right click context menu from showing up globally, and handle it manually. Any ideas on how I would go about this?

I'm not sure how to go about this, it seems like something easy but I just can't get the answer.
I've made a Window class in Lua for Love2d that handles the contents and drawing of windows/ ui.
I've given the window class a draw function, but how exactly would I cause that draw function to be called in love.draw()?
The "definition" of the class is as follows ( windowclass.lua)

Window = {}Window.__index = Window
-- everyone loves greek letters >> ∆∂ΘλωγΓ

windowlist = {}
window_min∆x = 96
window_min∆y = 96

window_max∆x = love.graphics.getHeight()

cs_rgb = {}

cs_rgb.edgehigh = 6
cs_rgb.desctxt = {111,113,117,255}
window_isGreyscale = true
-- state wether window is a teenager or not
window_isEdgey = false


function Window.create(name,desc,x,y,∆x,∆y,static,resize,z,hidden)
   local wind = {}
   setmetatable(wind,Window) 
   wind.name = name
   wind.desc = desc
   wind.x = x
   wind.y = y
   wind.∆x = math.clamp(window_min∆x, ∆x, window_max∆x) 
   wind.∆y = math.clamp(window_min∆y, ∆y, window_max∆y) 
   wind.isStatic = static
   wind.isResize = resize
   wind.z = z
   wind.isHidden = hidden
   table.insert(windowlist,self)
   return wind
end


function Window:setX(newx)
	self.x = newx
end


function Window:setY(newy)
	self.y = newy
end


function Window:setWidth(new∆x)
   self.∆x = new∆x
end


function Window:setHeight(new∆y)
   self.∆y = new∆y
end


function Window:setZ(newZ)
   self.z = newZ
end


function Window:getZ()
   return self.z
end


function Window:getWidth()
	return self.∆x
end


function Window:getHeight()
	return self.∆y
end


function Window:getResizable()
   return self.resize
end


function Window:getStatic()
   return self.isStatic()
end


function Window:draw()
   if not self.isHidden then
      setColourBG()
      love.graphics.rectangle("fill",self.x,self.y,self.∆x,self.∆y)
      if window_isEdgey then
         setColourBGEdge()
         love.graphics.rectangle("line",self.x,self.y+32,self.∆x,self.∆y-32)
      end
   end
end


function setColourBG()
   love.graphics.setColor(cs_rgb.bg[1],cs_rgb.bg[2],cs_rgb.bg[3],cs_rgb.bg[4])
end


function setColourBGEdge()
   love.graphics.setColor(cs_rgb.bg[1]+cs_rgb.edgehigh,cs_rgb.bg[2]+cs_rgb.edgehigh,cs_rgb.bg[3]+cs_rgb.edgehigh,cs_rgb.bg[4])
end




function Window:think()
end

This is loaded ( and so is exmaths.lua, a file that adds lerp and clamp to the maths class) to the main lua file as a required file.
So.. How exactly do I call this draw function for each window "entity" at love.draw()?

[twoski]

Would many people here find use in an OpenGL help thread? I am tempted to make one because i have a fair amount of opengl questions.

For the time being i'll post here.

Can someone explain why this doesn't draw anything?

void drawSkeleton()
{
	if (bones.size() == 0)
	{
		cout << "ERROR - NO BONES!" << endl;
		return;
	}

	glEnable(GL_LIGHTING);
	glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);
	glDisable(GL_CULL_FACE);
	glDisable(GL_POLYGON_OFFSET_FILL);

	glBegin(GL_LINES);
	glColor3f(1.0, 0, 0);

	for (std::vector<Bone>::size_type i = 0; i != bones.size(); i++) 
	{
		Joint jnta = *bones[i].jointA;
		Joint jntb = *bones[i].jointA;

		glVertex3f(jnta.vector[0], jnta.vector[1], jnta.vector[2]);
		glVertex3f(jntb.vector[0], jntb.vector[1], jntb.vector[2]);
	}

	glEnd();
}

I've read that GL_LINES can be problematic, i don't know what else to do. None of the bones draw.

I guess it's due to the sheer complexity of the language and the fact that include directives are just text expansions. For example your simple Hello World will feed the compiler with a file of more than 80.000 lines of code (in Visual Studio).

I'm interested in how you made a project take an hour to build, even a Source mod only takes about 5 to 10 minutes (maximum) to build from scratch. After that it's a matter of seconds unless you make huge modifications or rebuilt.

[WTF Nuke]

I'm thinking of making a top-down game in OpenGL, and I was wondering what would be the best way to approach the problem of seeing things that the character can see but that are occluded from the top-down perspective. I was thinking of having a cubemap without a top and bottom cast out from the player, which will store the depth of all the pixels it sees. Then, I would render from the top-down perspective using a stencil buffer and compare the depth of the bits that are visible and store the most deep one. I would then only render the deepest visible depth. This all sounds computationally intensive, and I was wondering if this would even work and if there's a better way to do it.
