Making a bot for the game HaxBall in python using OpenCV, need help in emulating the key presses according to its physics -


i have been working on haxball bot. don't know haxball is: simplistic football game (or soccer) in control circle , try shoot ball in goal, can play here. making bot simulate human using opencv image processing detect player , ball. program quite nicely.

the next step move player, have used pyautogui move player around. want player move 1 coordinate , here problem lies.

i able move object in bumpy way alternating between keydown , keyups, want smooth motion decided use kinematics , found player velocity , hence found time key down. player still overshoots , needs move back. physics of haxball such objects (player , ball) slide on field , acceleration of objects not constant.

would recommend better approach movement problem. code can found here.

def emulate():     epsilon = 1e-5     starttime = time.time()      # x,y = coords final position     # buffer = acceptable error     x,y,buffer = 276,132,40      # dict time how long press key     presskeys = {"w": 0.0, "a": 0.0, "s": 0.0, "d": 0.0}      while true:         if len(player_center)>0 , len(ball_center)>0 , len(player_speed)>0:               px,py,pr = player_center[-1][0], player_center[-1][1], player_radius             pvx,pvy = abs(player_speed[-1][0]),abs(player_speed[-1][1])             bx,by,br = ball_center[-1][0],   ball_center[-1][1],   ball_radius               if px-x>buffer:                 print("a")                 presskeys["a"] = (px-x)/(pvx+epsilon)              elif x-px>buffer:                 print("d")                 presskeys["d"] = (x - px) / (pvx + epsilon)              else:                 presskeys["a"] = 0.0                 presskeys["d"] = 0.0               if py-y>buffer:                 print("w")                 presskeys["w"] = (py - y) / (pvy + epsilon)              elif y-py>buffer:                 print("s")                 presskeys["s"] = (y - py) / (pvy + epsilon)              else:                 presskeys["w"] = 0.0                 presskeys["s"] = 0.0              currtime = time.time()             if currtime-starttime < presskeys["w"]:                 pyautogui.keydown("w")             else:                 pyautogui.keyup("w")              if currtime-starttime < presskeys["s"]:                 pyautogui.keydown("s")             else:                 pyautogui.keyup("s")              if currtime-starttime < presskeys["a"]:                 pyautogui.keydown("a")             else:                 pyautogui.keyup("a")              if currtime-starttime < presskeys["d"]:                 pyautogui.keydown("d")             else:                 pyautogui.keyup("d")

i apologized if couldnt explain (i have been bogged down problem), love make edits make more understandable. if wants work me on love work together.

vue.js - Create hooks for automated testing -

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...

Add new key value to json node in java -

i have json file : { "id":1, "name":"abc", "addressdetails": { "city":"newyork" } } i wanted add 1 more key-value ("pincode" : "414141") node 'addressdetails'. i tried using : objectmapper mapper = new objectmapper(); jsonnode root = mapper.readtree(new file("d://test.json")); objectnode node = mapper.createobjectnode(); node.with("addressdetails").put("pincode", "414141"); but it's not getting added, there way can ? you can try you should modify file path objectmapper mapper = new objectmapper(); objectnode nodes = mapper.readvalue(new file("d:\\test.txt"), objectnode.class); nodes.with("addressdetails").put("pincode", "414141"); mapper.writer().writevalue(new file("d:\\test.txt"), nodes);
