Input.GetKeyDown is not working

when change to another app, then return to exe player, sometimes Input.GetKeyDown is not working,

 

unity version is 5.6.5f1 32bit

 

I used Input.GetKeyDown in Update function.when Input.GetKeyDown is not working, the Input.inputString has right value.And no matter any key you click, the Input.anykeydown is always false.But when you press mouse, the Input.anykeydow has right value. Windows 7. Unity 5.6.5 f1

 

anybody konw??

 

Could you share the code that's not working correctly? Hard to say what your problem is without seeing the code.

Please use the code button or code tags when pasting it please.

 

Since you mentioned about the mouse click, this sound like it could be an app focus/Select issue.
I would have a look at:
MonoBehaviour.OnApplicationFocus(bool), make some testings, maybe force select or focus some object inside unity so that it starts working again properly.
Something you could do is also enable unity to run on background.

 

run on background is also selected.When press mouse, the input.anykeydow is detected,but just cann't detect keyboard.

 

Code (CSharp):

1. void Update () {
2.  
3.         if (Input.GetKeyDown(KeyCode.Q))
4.         {
5.             var panel = transform.parent.GetComponent<PanelMain>();
6.             panel.PressGemSkillBtn(GEM_PROP_TYPE.GEM_LOCK);
7.         }
8. }
