In case you need a simple script to move your game character using WASD buttons, feel free to use it:
float speed = 1f;
float rspeed = 5f;
if (Input.GetKey(KeyCode.A)){
transform.Translate(-speed * Time.deltaTime, 0f, 0f);
}
if (Input.GetKey(KeyCode.D)){
transform.Translate(speed * Time.deltaTime, 0f, 0f);
}
if (Input.GetKey(KeyCode.W)){
transform.Translate(0f, 0f, speed * Time.deltaTime);
}
if (Input.GetKey(KeyCode.S)){
transform.Translate(0f, 0f, -speed * Time.deltaTime);
}
if (Input.GetKey(KeyCode.Q)){
transform.Rotate(0f, -rspeed * Time.deltaTime, 0f);
}
if (Input.GetKey(KeyCode.E)){
transform.Rotate(0f, rspeed * Time.deltaTime, 0f);
}
