Well, I am making a gun sight on left shift trigger. In the inputs channel of the inspector window (Edit>Project Settings>Inputs) how do assign what left shift does??? Please Help.
You just need to make a new Input assignment , and look up the key that is used for left shift in the references.
As far as what the button will do … well thats up to you to script it to do so … for eg :
if(Input.GetButton("customButton")){
DoMyMethodHere();
}
