patch from Mitchell Stokes (moguri) simple use case scene.post_draw = [pyOpenGLFunc] this only needs to be set once, then the funcion runs each redraw. note, this patch also changes how python scripts run (not modules): Dont clear the namespace after running a script, since functions still use the namespace, BGE API is now better when dealing with stale data. made some changes to this patch. - assigning a list didnt decrement the existing list. - initialize as NULL rather then a blank list - dont use string comparisons for the callbacks, pass the python list to use instead. - dont check the list items are callable. python will display an error if they are not. - use python list macros that dont do any type checking sine blender does this when assigning the list ---- from tracker, edited since an updated patch changes some things. Here is a patch to be able to draw to the screen with BGE Python. This will be very handy for GUI stuff. This patch works by having the user register a callback in the scene. Two options are available KX_Scene.pre_draw and KX_Scene.post_draw. The difference between these is when Python draws to the screen (before or after the BGE). Each can take a list of functions. Here is an example that draws a blue semi-transparent
Welcome to the fun world of open source. For instructions on building and installing Blender, please see the file named INSTALL. ---------------------.Blanguages and the .blender directory--------------------- The .blender directory holds various data files for Blender. In the 2.28a release those are the .Blanguages file containing a list of translations, the translations themselves and a default ttf font. Blender checks for the presence of this directory in several locations: - the current directory - your home directory - On OSX, the blender bundle is also checked - On Windows, the installation dir is checked. If you get a 'File ".Blanguages" not found' warning, try to copy the .blender dir to one of these locations (your home directory being recommended). -------------------------------------Links-------------------------------------- Getting Involved: http://www.blender.org/community/get-involved Community: http://www.blender.org/Community Main blender development site: http://www.blender.org The Blender project homepage: http://projects.blender.org/projects/bf-blender Documentation: http://www.blender.org/education-help Bug tracker: http://www.blender.org/development/report-a-bug Feature request tracker: http://wiki.blender.org/index.php/Requests
