Declarations / Variables

[Nina]

Hi,

@S4V3D8YGR4C3

Why do we have to make it a new GameObject when we already declared it to be a Gameobject array at the top?

A variable is not an object. It’s a variable. In our case, pool is “empty” (= null). We have to explicitely assign an object reference.

With new GameObject[PoolSize], we create a new object of type GameObject[]. Then we assign the object reference to pool.

Why can’t we just write something like GameObject[Poolsize] pool to set the variable. Why do we need to use 2 separate lines of code for this process?

Because C# does not allow us to do that. This would be possible: GameObject[] pool = new GameObject[5];. However, we cannot use any variables at instance level because we cannot guarantee that the variable and its value exist when we try to access it. For this reason, variables can be used within methods only. When we execute method code blocks, the instance variables do exist. Why? Because that’s how C# works.

Is this what you wanted to know?
