Add showErrorLog flag

[takezoux2]

Add showErrorLog flag to switch show all exception log or not.

Motivation

If useSafeMode=true, DoTween vanishes all information about exception.But it make harder to track the cause of exception while debugging.

Hi Yoshiteru,

Thanks for the contribution! I will review the code asap (will probably need a few days, sorry for that) and see about including it.

Cheers,

Maybe you should use in-line if statements. Like ;

if(showErrorLog) Debug.Log();

Instead of ;

if(showErrorLog){
//Codes with Log
} else {
//Same codes without Log (occurs Duplicate codes)
}

I think, duplicate codes something that is undesirable on big & complex projects. Isn't it ? :)

I fixed to DRY

I wrote not DRY code for performance, but it was wrong.
I thought there is difference between catch{}and catch(Exception e){} in performance. I measured performance by the below code, but no differences are found.

        int count = 1000000;
        {
            var start = DateTime.Now;
            for (int i = 0; i < count; i++) {
                try {
                    ThrowException();
                } catch {
                }
            }
            var end = DateTime.Now;
            Debug.Log("With catch:" + (end - start));
        }
        {
            var start = DateTime.Now;
            for (int i = 0; i < count; i++) {
                try {
                    ThrowException();
                } catch (Exception e) {
                   
                }
            }
            var end = DateTime.Now;
            Debug.Log("With catch(Exception e):" + (end - start));
        }
// Result 
With catch:00:00:03.1103550
With catch(Exception e):00:00:03.1016900
