Instantiating an object issue

I try to instantiate an object. I set it as a public variable and I drag it to the inspector. If I try to Instantiate without checking if it's null, I get the error that the object I try to instantiate is null.

When I check if it's null, I cannot read the list that is filled, some lines above, but the Instantiation works.

The first prints the count correctly.
In the second print, inside the if block, the count is 0

Code (CSharp):

1.         print("??" + burningCellAdjacentsList.Count);
2.         if (fireClone != null && burningCellAdjacentsList.Count > 0) {
3.             print("??*" + burningCellAdjacentsList.Count);
4.         }
5.  

Did anyone handle a similar situation?

 

If the count is 0, the second if doesn't execute. With that in mind, it's more likely you have two copies of the script in your scene. One where the list has values, the other which doesn't.

 

I cannot understand why the check if not null blocks the array count value.

 

It doesn't. 0 is not greater than 0, so

burningCellAdjacentsList.Count > 0

is not true, and you won't get inside the if statement if 0 the array size is 0. Therefore, if you're getting two logs, it's because there are two of these scripts in your scene, like @Brathnann said.

 

I think there's a misunderstanding here -maybe I did not express it well. Line 1 prints 8. There's no other script in the scene, or object attached in the same script.

 

You're saying line 1 prints 8 and line 3 prints 0? There must be other code you're not sharing with us.

 

Agree with @PraetorBlue. There seems to be something missing if this code you shared is in a single method on the script, it would execute in order. It wouldn't change values between those two print calls on it's own.
