Save last value of a variable in Update()

Hi,
I have a variable in the Update() that updates its value at each frame. I have to pass this variable to another function of my script but when I do so the system crashes.

I'd like to know if there is a way to get / save the last value assumed by this variable and then pass it to the other function.

Thank you

 

This is what the private field does

 

If you could post an example of your code, using code tags, that will help us with the problem at hand.

Though to answer in a broad sense, having a variable declared outside your Update class and other method classes will allow all of them to access that value.

If the method is being called by your update class, you just need to pass the variable through method call, detailed like so (not sure if you're using C# or not: https://docs.microsoft.com/en-us/dotnet/csharp/methods#passing-parameters

 

@spiney199 Thank you for your reply. This an example of my code (posted only the parts and the variables that give me problems)

Code (CSharp):

1. public class EyeRecords : MonoBehaviour
2. {
3.     public float xL_PixText_Remap, xR_PixText_Remap;
4.    
5.  
6.     void Update()
7.     {
8.         xL_PixText_Remap = xL_pixText + 306;
9.    
10.         xR_PixText_Remap = xR_pixText + 306;
11.  
12.     }
13.  
14.     private void UpdateFilter(byte[] framebuffer)
15.     {
16.         newdstMat.put((int)xL_PixText_Remap, (int)xR_PixText_Remap, new byte[] { 127, 255, 0, 255 });
17.  
18.     }
19.  
20. }

When I hit play the system crashes. That's because it reads too many values?

 

Or you can save this variable to static class.
