Make targets appear / disappear

Hi,

in my Unity project I have three dots (see picture attached) and I want them to appear / disappear alternatively.

I assigned the value 1 for the direction of the right target and the value -1 for the direction of the left target and told them to appear or disappear in this way:

Code (CSharp):

1.  if (direction == 1)
2. {
3. RightTarget.SetActive(true);
4. yield return new WaitForSeconds(Targetduration);
5. RightTarget.SetActive(false);
6. }
7.  
8. if (direction == -1)
9. {
10. LeftTarget.SetActive(true);
11. yield return new WaitForSeconds(Targetduration);
12. LeftTarget.SetActive(false);
13. }

I want to do the same thing with the upper target.
If 1 and -1 stand for the right and the left dot which value do I have to give to the upper target?

Thank you

 

Well, I don't see a picture, but what I would do is create an array of the dots. Then using a coroutine, loop through the array to make each dot disappear or appear as needed as long as I needed. but that is assuming what you are doing is what I'm picturing.

 

Sorry, now I've fixed with the picture.
Thanks for your reply.

I actually use a coroutine anyway what I can't uderstand is why the values 1 and -1 make right and left targets appear / disappear correctly while if I assign for example the value 2 for the upper target it doesn't show what I would like.

Is there a rule to follow to assign the values for directions or are they given randomly?
Do I miss something I don't know?

 

Is

direction

a float? Don't compare floating point numbers for equality because sometimes what looks like 1 or 2 isn't actually 1 or 2 due to floating point imprecision. You can compare with Mathf.Approximately() but to be confident, do your own subtractive difference check.

 

Well, it's your code...

So the question is, how are you changing the value of direction? It may be best to show your full script instead of a snippet.
