if statement - Swift - How to check to see if sprite is assigned to certain image -


currently, in code, have skspritenode named ball randomly changes texture when makes contact anything. there 4 different textures/images each different colored ball. want use if else statement check see if ball equal specific texture can action.

i have code far, not check texture of ball sprite

func didbegincontact(contact: skphysicscontact) {       if ball.texture == sktexture(imagenamed: "ball2") && platform3.position.y <= 15 {          print("color matching")      } else {          print("not matching")     }   }

the if platform3.position.y <= 25 part works, ball.texture part of code not check see texture ball has.

set user data when assign color ball.

ball.userdata = ["color": 1] // later can check if (ball.userdata["color"] == 1) {

that proper way do. comparing integer faster.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
