if(isSmartcast()){
if(missTarget() or OutOfRange()) showRange();
else fire();
}


so new option like this
Smartcast & inRange : act like current smartcast range indicator option is off
Smartcast & OutOfRange : act like current smartcast range indicator option is on. but dont fire

If you are not sure if you can hit the target with smartcast, you just don't use the smartcast but normal cast. Not sure if this is necessary

new : fast and safe and noticeable

normal cast or smartcast range indicator option : slow
smartcast : not safe and dont know range (for nontarget skill, fire anyway. for targeting skill, do nothing.)

but true. not really necessary
smartcast. not really necessary
lol. not really necessary
life. not really necessary
