Scenario: I want to be able to click on a card if it’s not selected (and it is allowed to be selected) and move it up. Likewise, I would like to be able to click on a card if it is selected to move it down.
Issue: When I have the code to move the card up, given that it is allowed to be selected and that it is not currently selected, it works with no issues. It moves up as I expect and registers a single mouse click. However, when I add code to move the card back down if it is allowed to be selected and is currently selected, the card doesn’t move. A little bit of debugging later, it looks like it’s because it registers maybe two dozen mouse clicks, even though I’m using GetMouseButtonDown and clicking a single time.
I’m not sure what I’m doing wrong, but if someone could help, that would be awesome!
Code:
void Update()
{
GetMouseClick();
}
void GetMouseClick()
{
if (Input.GetMouseButtonDown(0))
{
Vector3 mousePosition = Camera.main.ScreenToWorldPoint(new Vector3(Input.mousePosition.x, Input.mousePosition.y, -10));
RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);
if (hit)
{
if (hit.collider.CompareTag("Card"))
{
ClickCard(hit.collider.gameObject);
}
}
}
}
void ClickCard(GameObject card)
{
Selectable selectable = card.GetComponent<Selectable>();
if (selectable.CanSelect && !selectable.IsSelected)
{
card.transform.Translate(0, 0.75f, 0);
selectable.IsSelected = true;
print("Clicked from Not Selected.");
}
else if (selectable.CanSelect && selectable.IsSelected)
{
card.transform.Translate(0, -0.75f, 0);
selectable.IsSelected = false;
print("Clicked from Selected.");
}
}
