Handling Inputs In Unity

Inputs in Unity allows the user to control the game using devices like the mouse + keyboard, controllers, touch, or gestures. In pc games, users often bind their movement inputs to “w”, “a”, “s”, and “d” while console gamers have their mapped to the left joystick.

Input Manager

The input manager window allows you to define input axes and associated actions.

Mapping inputs

In the script, we add inputs in the Update() function

void Update() {
        ProcessInput();
    }
private void ProcessInput(){
        if (Input.GetKey(KeyCode.Space)) {
            print("INPUT HAS BEEN TRIGGERED!!!!");
        } 
        if (Input.GetKey(KeyCode.A)) {
            rigidbody.AddRelativeForce(Vector3.left);
        } else if (Input.GetKey(KeyCode.D)){
            rigidbody.AddRelativeForce(Vector3.right);
        }
        if (Input.GetKey(KeyCode.W)) {
            rigidbody.AddRelativeForce(Vector3.up);
        } else if (Input.GetKey(KeyCode.S)){
            rigidbody.AddRelativeForce(Vector3.down);
        }
    }
