Question Continuous Spawn/Attack?

Edit: I finally found the correct word to google lol, "Repeating", which lead me to this page https://docs.unity3d.com/ScriptReference/MonoBehaviour.InvokeRepeating.html Hope this helps anyone else who is as bad as me >.<




Basically when I hold down Left Click, I want the game to keep on shooting until I release left click, but my code only shoots once per click. I seem to be googling the wrong things to find the solution.

Here's part of the script:

Code (CSharp):

1. void Update()
2.     {
3.         Vector2 bowPosition = transform.position;
4.         Vector2 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
5.         direction = mousePosition - bowPosition;
6.         transform.right = direction;
7.  
8.         if (timeBtwShots <= 0)
9.         {
10.             if (Input.GetMouseButtonDown(0))
11.             {
12.  
13.                 Shoot();
14.                 timeBtwShots = startTimeBtwShots;
15.             }
16.         }
17.         else
18.         {
19.             timeBtwShots -= Time.deltaTime;
20.         }
21.  
22.         for (int i = 0; i < numberOfPoints; i++)
23.         {
24.             points[i].transform.position = PointPosition(i * spaceBetweenPoints);
25.         }
26.     }

I've tried switching around the order of the "if"s and placed Shoot(); in different positions but i can't figure it out. I thought Input.GetMouseButtonDown(0) was a continuous thing? Or is the problem that the Shoot(); script isn't set to be continuous?

Code (CSharp):

1. void Shoot()
2.     {
3.         GameObject newArrow = Instantiate(arrow, shotPoint.position, shotPoint.rotation);
4.         newArrow.GetComponent<Rigidbody2D>().velocity = transform.right * launchForce;
5.  
6.         Destroy(newArrow, 10);
7.  
8.     }

Any help is greatly appreciated <3

 

Try using

Code (CSharp):

1. if (input.getkeydown("mouse1")
2. {
3. //code here
4. }
5.  

 

I see 2 potential solutions:
1) You could try using GetMouseButton instead: https://docs.unity3d.com/ScriptReference/Input.GetMouseButton.html

2) There is also the "up" counter part, true when the button is released.
So you could have a bool set to true at "Down" and false at "Up" and call shoot only when it is true.

 

I figured it out thanks, this is what I ended up with (although I think the old part that includes timeBtwShots isn't even being used now):

Code (CSharp):

1.         if (timeBtwShots <= 0)
2.         {
3.             if (Input.GetMouseButtonDown(0))
4.             {
5.                 // Starting in 0.5 seconds.
6.                 // a projectile will be launched every 1 second
7.                 InvokeRepeating("Shoot", 0.5f, 1.0f);
8.                 timeBtwShots = startTimeBtwShots;
9.             }
10.         }
11.         else
12.         {
13.             timeBtwShots -= Time.deltaTime;
14.         }
15.  
16.         for (int i = 0; i < numberOfPoints; i++)
17.         {
18.             points[i].transform.position = PointPosition(i * spaceBetweenPoints);
19.         }
20.         if (Input.GetMouseButtonUp(0))
21.         {
22.             CancelInvoke();
23.         }
24.     }

InvokeRepeating on GetButtonDown and CancelInvoke on GetButtonUp are the 2 biggies that solved it.

Here's a video of it working lol

I was too lazy to add a bow animation to the game (for now anyway), so I used magic to control the bow >.<
