Can i mix normal OpenGL ES 2.0 with Kobol2D / cocos2d on iOS? -


i making 2d game ios using kobold2d/cocos2d. i've decided try , add 3d buildings (think gta1/2 2d except buildings).

i know how opengl works im getting sorts of errors when try implement this.

my questions is: cocos2d prevent me using normal opengl calls ?,or should work fine if done correctly? every tutorial/example i've found uses cocos2d wrapper mixing opengl , cocos..

if have done before (mix own opengl es 2.0 code cocos2d) point me in right direction?

as long you're using cocos2d/kobold2d v2.x can use opengl es 2.0. can override/implement ccnode class' -(void) draw method , hack away.

there's 1 caveat: should prefer use cocos2d provided "ccstuffstuff" methods (for example ccdrawcolor) instead of opengl es methods because wrap behind scenes stuff performance reasons , compatibility. check existing cocos2d drawing code examples. 1 such example gles-render.cpp cocos2d+box2d projects, or ccdrawingprimitives.m file.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
