So I have an if statement that is supposed to change a variable if it detects change in position. I’ve looked on other forums of how to see change in position. The statement is running, but the variable isn’t changing.
Hey,
This is the wrong forum for this question, you’ll probably get a much quicker answer in the scripting forum:Unity Engine - Unity Discussions
When you ask this question there, you should include which variable isn’t changing. Also, you say that your method is running, but make sure it’s actually running by putting a Debug.Log()
line in your code.
Everything that Unrighteous says and also remember: SCREENSHOTS OF CODE ARE USELESS.
Instead, if you post a code snippet, ALWAYS USE CODE TAGS:

You must find a way to get the information you need in order to reason about what the problem is.
What is often happening in these cases is one of the following:
- the code you think is executing is not actually executing at all
- the code is executing far EARLIER or LATER than you think
- the code is executing far LESS OFTEN than you think
- the code is executing far MORE OFTEN than you think
- the code is executing on another GameObject than you think it is
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?
- are you meeting ALL the requirements to receive callbacks such as triggers / colliders (review the documentation)
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:
