having a problem with object pooling.

Pfayzer · September 9, 2017, 12:38pm

hey guys i am currently making a quiz game for our thesis. we were using the given object pooling at unity tutorial. and some of the features are working but. i am having a problem because i cant show the panel when the button clicked was correct. an the only panel which is showing is the wrongDisplay(Panel). and if I clicked the button on the wrongDisplay(Panel) my program hangs. which supposed to get back at the questionPanel to the other randomly picked question. can somebody help us because there’s only two weeks before our final defense. thank you.

here’s the code:

Code(CSharp):

@Cuttlas-U
my problem is that when i picked the correct answer, the correct answer panel didn’t show up instead the wrong display panel shows. and if I click the button that will return to the question display our program hang up. and didn’t return to the question panel that will shows the other randomly pick question.
