what happens if 2 events occur @ same time change value of variable? for instance, have 2 objects: a , b , loaded stage , stage variable named varx . the following code embedded in a 's fifth frame: stage.varx = 9 in other hand, have, in b 's fifth frame, following code: stage.varx = 2 so, what'll varx 's value, when both movieclips reach fifth frame? tl;dr a , b won't enter fifth frame @ same exact time, unless you're doing unusual. either a or b first, , whichever come last overwrite first one's value. make sure don't depend on them firing in order. you're doing unusual, it's still non-issue. this answered assuming you're referring single program multiple objects in stage. if you're talking multiple programs trying share sort of global stage state instead (i'm not sure whether share same stage object or not), can't sure, work same way. flash generally not use multi-threading. in fa...

this sounded trivial question did not come across solid/best practice solution on how asking question here. now, let's imagine have work couple of ".txt" files in our code in class library. now, think there 3 major ways handle this: just put in bin/debug/resources folder of calling application , in code use "resources\*.txt". think simplest , unobtrusive way handle this. however, there many trivial problems it: when check in source control not check-in files inside bin/debug folder so in case, adding folder 1 level above , writting post-build scripts efficient option guess? add resources folder on same level bin folder . way can manage using source control. when need reference through our code becomes tricky we can reference files assuming binary folder's structure bin/debug , reference resources folder ..\..\resources but structure not guaranteed if binary folder structure bin/ (without debug folder in it) ../../resources going fail ...

i've been trying head around solution camera movement. these parameters needs work , thoughts had tried: camera movement / not world movement raycast move camera accurately along terrain touch movement works "grabbing" terrain towards or "pushing" away screen space world space not work because of angle of camera so thoughts have lead me devise solution grab vector3 point ray hits ground under finger on fingerdown move camera in opposite direction real world distance between origin , movingpoint. if makes sense. i'm pretty confused either confirm or deny idea , give clear way forward =) i'm using asset called leantouch (brilliant piece of free scripts) touch inputs , far brain wants go: (lol) var finger = lean.leantouch.fingers [lean.leantouch.fingers.count - 1]; var ray = finger.getray (); int layermask = (1 << 8); physics.raycast (ray, out hit, mathf.infinity, layermask); initialhit = hit.transform.position; btw i'm workin...

i in need way interpret x ^ y (i aware there such solutions available, challenging myself go "library-free"). thought using regexp, such: (\(*\w+\)*|\(*math.pow\(\w+,\w+\)\)*=*)+\s*\^\s*(\(*\w\)*)+\)* ( http://regexr.com/3b0dl ) , replace string "math.pow($1,$2)" . now, works cases i've tested far, save following: 1 - paren surrounding expression (2 ^ (5)) which replaces thus: math.pow((2,(5))) which evaluates (2,(5) . there way can fix regexp matches ) many times matched ( in second catch group? 2 - multiple iteration (2 ^ 3) ^ 5 is replaced with math.pow((2,3)) ^ 5 which leaves unevaluated ^ . figure may done while(input.match("^"){...} sort thing, want know if possible via regexp. thank in advance help.

i plotting barplot error bars. , here's got far. problem error bars not appear in place should be. if don't force id levels, removing df2id <- factor(df2$id, level = c('gary','jack', 'alice')) line, looks fine. id = c(rep('gary',10), rep('jack',10), rep('alice',10)) #gary has lowest mean , sd, alice has highest mean , sd var1 = c(rnorm(1:10)*1+10,rnorm(1:10)*10+20, rnorm(1:10)*100+30) df <-data.frame(id = id, var1 = var1) df2 <- ddply(df, 'id', summarise, mean = mean(var1), sd = sd(var1)) df2$id <- factor(df2$id, level = c('gary','jack', 'alice')) limits <- aes(ymax = df2$mean + df2$sd, ymin = df2$mean - df2$sd) ggplot(df2, aes(y=mean, x=id))+geom_bar(stat='identity')+ geom_errorbar(limits)+ facet_grid(.~id) but need keep line can re-order sequence of panels. how can make error bars re-ordered too? you should never use data.frame$column ggplot, forces...

i'm confused whether it's compulsory use facebook login on site, if want user able explicitly publish custom story. for example, i've created custom "review" action. hasn't been approved yet, works developer/test accounts. i want user share story on facebook: if yes clicked, fb.ui(method: 'share_open_graph', ... ) called, brings dialog: is alone not acceptable case using/approving custom story? when attempt submit action review, i'm forced declare app uses facebook login. have no need call fb.login() anywhere. above process implicitly constitute facebook login? if not, why need shoehorn facebook login app, when want accomplish? edit - evidence: note how submit review greyed out, until tick checkbox: here's snippet documentation : this example open graph action rejected for: listing website not use facebook login... so after really laborious review process , culminated in some direct support , ...

i able find text using element.all(by.repeater()) in protractor , using each check matching text. problem exiting once match done , clicking on matched element. i tried using .each() , unable exit iteration. any suggestions? in case, each() not choice. it sounds filtering , example: element.all(by.repeater("test in tests")).filter(function (elm) { return elm.gettext().then(function (text) { return text === "desired text"; }); }).then(function(filteredelements) { filteredelements[0].click(); });

is there way open kendo ui window @ mouse pointer? i can see in telerik demo window api , can open on center of page, want open @ mouse pointer. first, keep current mouse position stored somewhere: var currentmousepos = { x: -1, y: -1 }; $(document).mousemove(function(event) { currentmousepos.x = event.pagex; currentmousepos.y = event.pagey; }); then, when opening kendo window: $("#window").closest(".k-window").css({ top: currentmousepos.y, left: currentmousepos.x });

often after unzipping file end directory containing nothing directory (e.g., mkdir foo; cd foo; tar xzf ~/bar.tgz may produce nothing bar directory in foo ). wanted write script collapse down single directory, if there dot files in nested directory complicates things bit. here's naive implementation: mv -i $1/* $1/.* . rmdir $1 the problem here it'll try move . , .. , ask overwrite ./.? (y/n [n]) . can around checking each file in turn: ifs=$'\n' file in $1/* $1/.*; if [ "$file" != "$1/." ] && [ "$file" != "$1/.." ]; mv -i $file . fi done rmdir $1 but seems inelegant workaround. tried cleaner method using find : for file in $(find $1); mv -i $file . done rmdir $1 but find $1 give $1 result, gives error of mv: bar , ./bar identical . while second method seems work, there better way achieve this? turn on dotglob shell option, allows pattern match files beginning . . s...
