Many people may agree that error messages are annoying.
Sometimes the script error messages hardly make any difference at all during the gameplay, in a mission. If you're playing a mission, you hardly care about what's going wrong with the game sometimes. SOMETIMES.
I would love to have an option to disable that enormous black rectangle that shows up nearly in front of my ironsights.
Script something incorrectly
Use the script
Notice the error message. Sometimes, you don't care about it, and don't want it to be shown, even though something is going wrong.
Add it as an OPTION, something that can be disabled IF YOU WANT TO.
Thank you for your support.
Remove showScriptErrors from your startup line and don't complain about feature you've enabled yourself.
Launch parameters in Steam's Arma 3 properties window. DarkWanderer is right, script error messages are invisible unless you manually enable them.
@AD2001 are you on DEV branch? DEV branch has mandatory error reporting, you can't switch it off.
