unity3d - 2D camera positioning in Unity -


i'm writing 2d game in unity , force orthogonal camera's view frustum altered on right-hand side according device's aspect ratio, left/bottom being set 0,0

i.e.: i'd bounds of camera's y frustum to 0 @ bottom , 10 @ top. easy , i've done moving camera's position 5 , setting camera size 5 (i'm presuming has worked). (also, there's no real reason why i've gone 10, seems round number...)

when scene starts i'd move camera's x frustum left 0 , right whatever aspect ratio demands: somewhere between 4:3 , 16:9 depending on device. pretty mean setting camera's x translation presume, i'm touch lost on how aspect ratio, , calculate should be?

...and here's answer:

vector3 pos = new vector3(5.0f * camera.main.aspect, 5.0f, -10.0f); camera.main.gameobject.transform.position = pos;

which popped main.cs script, under start() function. 5.0f half height of 2d camera'a othrogonalsize (as mentioned in question above), , -10.0f default z-position main camera in 2d game.

javascript - RequestAnimationFrame not working when exiting fullscreen switching space on Safari -

request animation frame stops working when exiting fullscreen clicking on original space's safari window. fine if fullscreen mode canceled escape key or calling cancelfullscreen(). steps reproduce: open https://dl.dropboxusercontent.com/u/769042/prezi/safari-fullscreen.html click "draw raf", kittie appears click "fullscreen", go fullscreen click "draw raf", kittie appears go space original safari was, showing "click exit fullscreen mode", click anywhere, out fullscreen click "draw raf", nothing happens what handling click calling: window.requestanimationframe(draw); which draws on canvas context: function draw() { ctx.drawimage(img, math.random()*500|0, math.random()*400|0, 100, 100); } i checked .hidden , .visibilitystate, updated correctly. tested on osx 10.9.3, safari 7.0.4 (9537.76.4). has workaround/solution other switching old settimeout? this sounds webkit bug 88940 : using reque

Python ctypes access violation with const pointer arguments -

i have api i'm trying wrap in python (2.7.6 on win7) code using ctypes. here's api: client_dllfunc bool clientapi search_exporttoclipcopy(clienthsearch handle, int channel, lpctstr filename, const time_t& from, const time_t& to, const bool* cameras, int length, bool usepassword, lpctstr password, bool includetextin = false, bool excludeplayer = false); the issue i'm having cameras argument; , i've had issue other const pointer arguments well. here's how i'm wrapping api: def search_exporttoclipcopy(self, hsearch, csearch, filename, tfrom, tto, cameras, length, usepassword, password, includetextin=true, excludeplayer=false): exporttoclipcopy = self.sdkdll.search_exporttoclipcopy exporttoclipcopy.argtypes = [c_int, c_int, c_wchar_p, c_long, c_long, pointer(c_bool), c_int, c_bool, c_wchar_p, c_bool, c_bool] exporttoclipcopy.restype = c_bool exporttoclipcopy(hsearch, csearch, filename, tfrom, tto, cameras, length, usepassword, pass
