Button.OnClick() is not evoked

[Kurt-Dekker]

Is the button not working? We know buttons work so make a new one. Get it working.

If the button is working but the “whatever it does” part isn’t, find out with Debug.Log()

To help gain more insight into your problem, I recommend liberally sprinkling Debug.Log() statements through your code to display information in realtime.

Doing this should help you answer these types of questions:

• is this code even running? which parts are running? how often does it run? what order does it run in?
• what are the values of the variables involved? Are they initialized? Are the values reasonable?

Knowing this information will help you reason about the behavior you are seeing.

You can also put in Debug.Break() to pause the Editor when certain interesting pieces of code run, and then study the scene

You could also just display various important quantities in UI Text elements to watch them change as you play the game.

If you are running a mobile device you can also view the console output. Google for how on your particular mobile target.

Here’s an example of putting in a laser-focused Debug.Log() and how that can save you a TON of time wallowing around speculating what might be going wrong:

Coroutine missing hint and error

This is so unnecessary. Use the beauty and power of instantly and immediately putting a Debug.Log() statement into the very start of the coroutine, right at the top. Do this always at the very first sign of trouble or question in your mind. The instant you did this you would see “Oh man, this code is simply not getting run!” And you could LASER-FOCUS 100% your efforts on studying what you expect to run it, eg., the call location, and isolate why it is not running. You would look at literall…

Errors are there to help you. It's a good idea to try and learn how to understand them. Try to apply the breakdown in this post of your original error to the new error you're receiving. If you don't understand a word, don't just gloss over it. Ask what the word means here, or research it elsewhere. Cultivating a habit of research will pay dividends for you in every part of your coding journey. Here's a breakdown of your specific error, but try applying this process to any other error you may e…
