Question by iveL_newO · May 01, 2018 at 05:07 AM · instantiatebuttonassignment

The variable has not been assigned even though it has been

Unity says that my button object has not been assigned even though it has. I am instantiating a canvas prefab for every player that has three buttons in it, I need to reference them so that I can make them disappear after they are clicked. In the photo I have clicked the play button.

 playButton = canvas.transform.GetChild (2).gameObject;
 blueButton = canvas.transform.GetChild (4).gameObject;
 blueButton.SetActive (false);
 redButton = canvas.transform.GetChild (3).gameObject;
 redButton.SetActive (false);
 print (playButton.name + blueButton.name + redButton.name);

Is the playButton public and visible in the Inspector? I bet it is not assigned in the Inspector

From the console output in the screenshot it can be seen that playButton gets assigned, but the variable playButton in playercontroller.play() does not have a value. Are they the same variable? Do you try to set playButton anywhere else (that might return null)? Are you trying to access the button variable on the server?

Are the button variables of the type "GameObject"?

Another thing is that I am referencing the variable in an OnClick function. @keckluis

I fixed it.

I was instantiating the buttons and the player, the buttons were using onClick listeners from the player's script so I just had to assign the listeners via script. Thank you
