[pygame] planes 0.6.0 released
Hey, I have just released v0.6.0 of the planes module. planes is a hierarchical surface framework for PyGame, extending it with a hierarchy of mouse-sensitive, draggable Surfaces that can be used as sprites, windows, icons or other interactive elements. In addition, the planes.gui module provides basic GUI elements like container, label, text box, option list and button. http://florian-berger.de/en/software/planes Changes: planes now logs runtime statistics and displays them when F12 is pressed. There is a font manager class now, and planes comes bundled with a selection of free fonts for instant use. A font usage example is included. There is a new widget planes.gui.ProgressBar. All gfx and font resources are now bundled in a 'resources.zip' file which is distributed along with planes. planes now uses cx_Freeze to build executables. Added mouse wheel support for the Plane class and the PlusMinusBox widget specifically. Optimized Plane.render() a little to check whether subplanes actually intersect with Display.rect. Bug fixes and enhancements in Plane.render(), gui.Container.sub(), and 'planes_interactive.py'. Docs update. planes is quite powerful, but sadly lacks a tutorial to get started. This will be added in the beta (0.9.x) releases. planes powers the 2D client of the Fabula engine: http://fabula-engine.org/ Cheers, Florian

Re: [pygame] cx_Freeze and non-BMP images: my possible solution
Hi, Rastagong : > > I have been struggling for a while with cx_Freeze to have my Windows > executables handle PNG images, and more generally non-BMP images. > [...] > Does it work for you too? I have been using Python 3.1, Pygame 1.9.1 and cx_Freeze 4.2.2 on Win2k for a while now, and I have never had any issues with non-BMP images. My game engine uses PNG images extensively, and everything works out of the box here. Kind regards, Florian
Re: [pygame] Surface.blit() BLEND_ADD vs. BLEND_RGBA_ADD
Hi! René Dudfield : > > Maybe the RGBA_PREMULT of pygame.image.tostring could be used... It works. Thanks, man! A visual example of the problem and your solution is at http://pastebin.com/0JJQVYe8 . Just curious, how bad is the performance penalty for this double conversion step? Would it be better to have a BLEND_ADD_PREMULT blit mode instead, i.e. put the premultiplication in the blitting code? Kind regards, Florian

Re: [pygame] Surface.blit() BLEND_ADD vs. BLEND_RGBA_ADD
Hi René! René Dudfield : > > #define BLEND_RGBA_ADD(tmp, sR, sG, sB, sA, dR, dG, dB, dA) \ > tmp = dR + sR; dR = (tmp <= 255 ? tmp : 255); \ > tmp = dG + sG; dG = (tmp <= 255 ? tmp : 255); \ > tmp = dB + sB; dB = (tmp <= 255 ? tmp : 255); \ > tmp = dA + sA; dA = (tmp <= 255 ? tmp : 255); Ah. Intuitively I thought it would multiply the RGB addition by the alpha, thus adding RGB(0, 0, 0) for fully transparent pixels. Apparently it is much simpler. :-) Still, that would be a useful operation for sprite and icon effects. In my case I use BLEND_ADD to quickly and conveniently highlight a sprite. Now I will have to mess with the source PNGs to make sure that the RGB color for fully transparent pixels is actually black. Regards, Florian
Re: [pygame] Surface.blit() BLEND_ADD vs. BLEND_RGBA_ADD
Hi! Ian Mallett : > > Simply call .convert_alpha() on each surface after you make your > window. This clears up most problems. I am doing that already. In fact I blit the sprite, so I can see that alpha works; then I create a Surface.copy(), manipulate that and blit it over the sprite using BLEND_RGBA_ADD. The result is that the blit incorporates the RGB values of the fully transparent pixels and adds them as well, resulting in an ugly square around the sprite. The solution in my case is to make sure that the transparent pixels also have a (0, 0, 0) RGB value. But this is annoying. I think this calls for a bug report. ;-) Regards, Florian
[pygame] Surface.blit() BLEND_ADD vs. BLEND_RGBA_ADD
Hi, I am toying around with the above blitting flags. I am blitting a RGBA sprite surrounded by transparent (i.e. alpha) pixels on a solid RGBA surface (at least I suppose it is so, both are created from RGBA PNG images). In my test setup, there is no difference between BLEND_ADD and BLEND_RGBA_ADD. I hoped that the latter would honor alpha transparency, and not add color values of transparent pixels, but this seems not to be the case. :-/ Has anyone played with this? What is the difference between these two supposed to be? Thanks! Florian
[pygame] fix homebrew install instructions link on pygame.org
Hi! On http://pygame.org/download.shtml, under "Macintosh", there is a link to "homebrew install instructions" pointing to https://bitbucket.org/pygame/pygame/issue/82/homebrew-on-leopard-fails-to-install#comment-627494 This should now point to the updated instructions at https://bitbucket.org/pygame/pygame/issue/82/homebrew-on-leopard-fails-to-install#comment-636765 This one just bit me.
