Did a shitload of refactoring and all objects (like shaders) can now be shared between windows. Apparently sharing didn't work properly with a deprecated context so everything is now fully non-deprecated.

[bobthe2lol]

Messing around with Python and SFML. I wrote a Love2D-like interface that provides functions like draw and update, and mouse etc. I might make it more love-like by making functions for actually drawing primitives, instead of having to create objects for them. That's one thing I don't like about SFML. If I want to draw a rectangle, I need four to six lines.

I need to make the quadtree accept objects into nodes that have children.

Here's the wrapping code, if you're interested:

class SfHelper:
    window = None
    vidmode = None
    cls = True

    def __init__(self,width=700,height=700,title="Python SFML Window.",clear=True,load=None,draw=None,update=None,defaultevent=None,mouseclick=None,mousemove=None,keypress=None):
        self.vidmode = sf.VideoMode(width,height)
        self.window = sf.RenderWindow(self.vidmode,title)
        print "Window created."
        self.cls = clear
        self.load = load
        self.draw = draw
        self.update = update
        self.defaultevent = defaultevent
        self.mousemove = mousemove
        self.mouseclick = mouseclick
        self.keypress = keypress

    def begin(self):
        CallIfExists(self.load)
        now = curtime()
        while self.window.is_open:
            for event in self.window.events:
                if type(event) is sf.MouseMoveEvent:
                    CallIfExists(self.mousemove,event)
                elif type(event) is sf.MouseButtonEvent and event.released:
                    CallIfExists(self.mouseclick,event)
                elif type(event) is sf.KeyEvent and event.pressed:
                    CallIfExists(self.keypress,event)
                else:
                    CallIfExists(self.defaultevent,event)
                if type(event) is sf.CloseEvent and self.window.is_open:
                    print "Closing window."
                    self.window.close()
            dt = curtime()-now
            now = curtime()
            CallIfExists(self.update,dt)
            if self.cls:
                self.window.clear()
            CallIfExists(self.draw,self.window)
            self.window.display()

Then I've got a Game superclass that subscribes to all these events and has overridable functions for them:

class Game:
	def __init__(self):
		self.helper = SfHelper(load=self.load,draw=self.draw,update=self.update,mouseclick=self.mouseclick,mousemove=self.mousemove,keypress=self.keypress )	
		self.helper.begin()

	def load(self):
		pass

	def draw(self,window):
		pass

	def update(self,dt):
		pass

	def mouseclick(self,event):
		pass

	def mousemove(self,event):
		pass

	def keypress(self,event):
		pass

I'm finally seriously working on my opengl game engine, which I plan on using for 2D games. It is extremely noob friendly and probably bad for any kind of practical game usage. But then again I am no master developer. This is all using modern opengl rendering techniques, such as VBOs and custom shaders, and I am manipulating the matrices in the code etc. I have just covered all the ugly stuff with nice functions for simplicity sake. Any feedback would be pretty cool.

This is how entities can be manipulated just using a function ( there is also scaling and rotation )

You can assign geometry to any kind of object. Right now I only have a Quad class ( it derives from Geometry ) but I plan on adding circles and such. The geometry can then be manipulated.
[IMG]http://i.imgur.com/RRBKpBh.png[/IMG]

This is some of the render call for some geometry. Like I said, this is not the deprecated functions, I just named them similar to the old deprecated ones because those are very familiar to me.

This is the end result. Time to make the call of duty killer :wink:

I mean, which one looks better to you:

self.rectshape = sf.RectangleShape()
self.rectshape.size = self.bounds.size
self.rectshape.position = self.min
self.rectshape.fill_color = sf.Color(100,149,237)
...
window.draw(self.rectshape)

or

drawRect(self.min,self.bounds.size,sf.Color(100,149,237),window)

If OPTLINK only would produce executables that work with GDB.. I'll fix it tomorrow on linux then

So the FPP's bot has markov chains built in (it has for a while now)
If you want to test this out

* [URL="steam://friends/joinchat/103582791430091926"]Click Here To Enter FPP[/URL]
* Pick a single word to start with (It has to be a word that would be said in a chat room since it only learns off the chat room)
* Type into the chat "]<word you picked>"
* Watch as the bot builds a sentence.

But anyway, I just added twitter support so it will tweet these things every hour!

I got problems once with multithreaded DirectX (actually, XNA with C#) with SpriteBatch.
So is it even possible to do multithreaded graphic calls?

Multithreaded DirectX works quite well afaik. In OpenGL you need a context for each thread and you can only share specific stuff between them.

Multi-threading is used to upload data to the GPU, rather than issue draw calls (draws don't always happen when you make the call anyway so threading doesn't really help you there).

finally managed to get the lua working in blops2
it uses havok script(custom lua vm) which i think can only be bought so that makes the reversing a bit difficult
Havn't managed to get a full _G dump yet, the tostring crashes sometimes

Edit:
here is _G dump: [url]http://pastebin.com/q6PEaFkf[/url]
CriticalSections was the problem

[redx475]

My virtual machine's opcodes take arguments in two ways: a list of arguments passed to them, or they can pop them from the stack. Most used to use the list method, which made it impossible to do dynamic memory allocation inside of a script. Now, most opcodes pop from the stack instead, and the assembler has some syntactic sugar that allows you to specify arguments normally instead of manually adding push opcodes.

The downside of this is that I can't check the argument count at compile time.

EDIT:

I just realized I never implemented less-than/greater-than...

Making a more or less terraria clone with SFML and fully integrated lua modding. I thought this was a neat milestone, and perl thought i should share it, so i am. :v:

What library are you using to integrate Lua into C# or is it your own solution?

[r0b0tsquid]

Writing a more comprehensive emulator so I can debug code for the OISC on my machine, I couldn't find any grid controls that suited my needs so I ended up whipping up my own barebones hex editor:
[IMG]http://i.imgur.com/j5WbOSR.png[/IMG]

The thing that makes it useful is that it doesn't actually store the data itself, you just pass it a pointer to an external array - this means I can have it sharing memory space with a VM for my computer, and it'll asynchronously display the memory contents as the VM runs :)
