How to make my spaceship move by mouse?

Questions & Answers
1

I am trying to make a game very similar to space shooters project. I am adding a few tweaks but the main problem I am having is that I cannot write a valid c# script for the spaceship movement. The game is in 2d, but I am using 3d models and 3d physics. I want to make spaceship move according to mouse position. I am kinda lost in scripting reference and I do not know what to use. Any suggestions, hints or examples would be very apreciated!

As you said, despite the 3d environment/content you can use 2D logic. With your axes of choice, e.g. x & y axes for horizontal and vertical movement (neglecting the z-axis) you could write a mapping between the mouse motion and the ship’s motion. What you need is the following

  • Vector2 deltaMousePosition … this will be adjusted in the update loop with Unity’s Input.GetAxis("Mouse X") and Input.GetAxis("Mouse Y")
  • In your update loop add this deltaMousePosition to the ship’s transform.position, but make sure to clamp it so it does not go off screen ( a simple if statements should suffice)

That is the basic solution. Hope this helps, otherwise please be more specific with your question.

// Update is called once per frame
private void Update()
{
if (enableThis) Move();
}

private void Move()
{
    //var deltaX = Input.GetAxis("Horizontal") * Time.deltaTime * moveSpeed;
    var deltaX = Input.GetAxis("Mouse X");
    var newXPos = Mathf.Clamp(transform.position.x + deltaX, xMin, xMax);

    transform.position = new Vector3(newXPos, transform.position.y, transform.position.z);
}
