i had question regarding angular 2. we using laravel 5.2 our backend or api provider , want write our frontend in angular 2. best way use them together? serve angular 2 files via laravel on same node. have separate nodes front end , backend, angular 2 runs on 1st node served node.js (as of examples on angular 2 show) , api services using laravel on 2nd node. i couldn't find best guide satisfy 1st option. can suggest how proceed? i believe both practices fine. if host on same node, won't have specify api node when making calls. if see backend api being more general service other applications building, consider second, more general node.

i have data actors movement being read in file @ start of game. data gets read in contains vector positions actor should move next. have actor moving position position no problem... until start add animation skeletal mesh attached actor. my problem: how can found out velocity work out animation play idle, walk, jog , running? doesnt have velocity lerping position: setactorlocation(fmath::lerp(getactorlocation(), newpos, 0.01)); any thoughts on how set right animation based on distance travel , speed? should move actors movement character can use addmovementinput velocity. then, if go down route, how say: move character current position, next position in x amount of time giving character correct velocity use in animation selection. can normalize difference between 2 vector lengths (getworldlocation) , use abs(floating point) result x variable put 1d blend space idle, walk, jog, run in animation bp? sure account "acceptance radius" or else once gets locat...
