C / C++ - How to manage the cycles in a video game? -


i have made video games in c (small personal project). , problem encountered every time same, how manage cycles in game.

for example, coded snake in sfml. handled cycles frame rates: 5 frame rates while normal, , power up, changed 10. works. it's hideous. , won't work correctly bad computer. in same idea, made game decided cycle equal turn of loop (with infinite loop). same problem, high performance computer go faster low one.

so, can advice me on how manage correctly , cycles in video game.

thanks in advance !

in broad terms, need model game state such can "advance" given increment of time, , then, during each cycle of main loop, determine how time has elapsed (typically small fraction of second) , advance game state much. how games appear work smoothly regardless of frame rate.

the interval becomes scaling factor on movement. example, if snake moving forward @ 5 units of distance per second, , during main loop find 0.01 seconds have elapsed since last time snake moved, advance snake (0.01 * 5) unit of distance during loop.

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...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
