Bug Why doesn't the bool value change?

Hi ,I have this code:

Code (CSharp):

1.  
2. if (Input.GetButtonDown("Cancel") && gameIsPaused == false)
3. {
4.     gameIsPaused = true;
5. }
6. if (Input.GetButtonDown("Cancel") && gameIsPaused == true)
7. {        
8.     gameIsPaused = false;
9. }
10.  

The problem is that the gameIsPaused bool does not change to true when I press the button, but if I change the bool in the inspector to true and then press the button, the bool value becomes false.
Why does that happends?
Thanks

 

Because the first check happens, you set the bool true... then in the SAME EXACT FRAME, the second if flows and actually succeeds.

The above code is a classic example of "repeating yourself."

The DRY principle states "don't repeat yourself."

Let me offer you a better way:

Code (csharp):

1. if (Input.GetButtonDown("Cancel"))
2. {
3.   // toggle on / off
4.   gameIsPaused = !gameIsPaused;
5. }

Note how there is no repeated code.

 

the way kurt offers is much better and easier to read, but also if you do hit similar cases and its not just a toggle, making your 2nd statement a "else if" would have ensured on any given frame only one of those 2 blocks executes
