Setting my position to the position of a gameobject
I'm trying to make a farming game thing and I want to move my seeds to a gameobject above my crop plot. What I want to accomplish: when I'm moving the seeds and I collided with the crop plot and when I release my mouse button it sets my position to the gameobject above the crop plot. It isn't working and I can't seem to figure out why . So here is the code thanks in advance :)
private float startPosX;
private float startPosY;
private bool moving;
public Transform cropPlotAbove;
public Transform myTransform;
void Start()
{
myTransform = GetComponent<Transform>();
}
void Update()
{
if (moving)
{
Vector3 mousePos;
mousePos = Input.mousePosition;
mousePos = Camera.main.ScreenToWorldPoint(mousePos);
this.transform.localPosition = new Vector3(mousePos.x - startPosX, mousePos.y - startPosY, this.transform.localPosition.z);
}
}
private void OnMouseDown()
{
if (Input.GetMouseButton(0))
{
Vector3 mousePos;
mousePos = Input.mousePosition;
mousePos = Camera.main.ScreenToWorldPoint(mousePos);
startPosX = mousePos.x - this.transform.localPosition.x;
startPosY = mousePos.y - this.transform.localPosition.y;
moving = true;
}
}
private void OnMouseUp()
{
moving = false;
}
private void OnCollisionEnter2D(Collision2D collision)
{
if(moving == true && collision.gameObject.tag == ("Crop Plot") && Input.GetMouseButtonUp(0))
{
myTransform.transform.position = cropPlotAbove.transform.position;
}
}
Please when you post code - click on the binary numbers 101 010 at the top and then it opens a block into which you can copy and paste your code.
Your using Vector2 and Vector3 - but I assume from the Collision2D that you're doing a 2D game.
You would need to convert your mouse position to a vector 2 - you can do this:
if (Input.GetMouseButtonDown(0))
{
Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
Vector2 mousePos2D = new Vector2(mousePos.x, mousePos.y);
}
Then you'd probably have to do some functions in void update -
If user clicks on the seed set bool moving to true.
If bool moving is on always set the seed's transform to mousePos2D.
If there is a collision and bool moving is on, set bool moving to false and move the seed to the position of the collision object.
