Input.GetMouseButtonDown(0) problem

i dont know what happen to my unity. before, the game object must be click to trigger the effect but for some reason, it trigger whenever I click anywhere? what happen? pls help… :frowning:

same thing happens even if I created a new project…

it could happen because your “Input.GetMouseButtonDown(0)” is not int the “OnTriggerEnter()” “i guess”, but the best is building a raycast to do this
