Get/Set for reference of moveplate doesn't seem to be used within scripts?

[AoifeHughes]

Hi,

Thanks for your tutorials, could you help me with clarifying what these getters/setters are doing and why they are needed. I can't understand how the GameObject reference is set if nothing ever calls it? Does unity do this automaticaly with the 2D collider?

Chess_App/Assets/Scripts/MovePlate.cs

Line 69 in 6b19092

public void SetReference(GameObject obj)

Hi, So a getter and setter is used because “reference” variable is private. So you cannot access a private variable outside of this class. This is just an organizational thing that is standard in programming, you definitely don’t have to do it this way, you could make the variable public, but in order to keep the code “clean” and easily extensible (for example working with Interfaces or if this code is being called from many places) it is common to use this pattern. I believe this function is being called from a different script, if not it just means it’s a function that has no use and can be removed. The collider doesn’t use this function automatically.
