You do realize, you don't provide any context to this problem;

How have you created your moving object (= character)?

Are you using some pre-made asset, Unity assets or some custom setup you created?

What does your code look like?

List goes on... besides the fact that FPS (first person shooter) games are seldom 2D games so this probably should have been posted to general scripting area.

How do make a ground check?
[Project Info: 2D, for Android, 3 UI buttons: Right, left and jump, player infinitely jumps. I want the player to jump only when he is touching the ground, here is the project picture]

 

This video has exactly what youre looking for.
