Good evening beloved developers, for those still using C-Script (like me) I found a way faking switch () by using the while () instuction. Maybe it looks a bit strange in the beginning, but it aviods those if () structures that look like chinese temples.
while (1) {
// Case 1
if (expression) {
instructions
break;
}
// Case 2
if (expression) {
instructions
break;
}
// And so on...
// Default part
instructions
break;
}

Why do you put that in a loop? The loop does not make sense at all as it is never executed.

@Lion_Ts A6.31.4 C-Script (and earlyer) does understand if-structures without {} (having only one following command, which can be another if, to create what you posted). Your if structure in C-Script looks like this:
if (expression) {
} else { if (expression) {
} else { if (expression) {
} else {
} } }
And is aweful to count the amount of closing-brackets. So why the while? To be able to jump to the end of the fake-switch by using break;.

if else if else does actually not represent the logic behind a switch instruction. In a switch instruction you have multiple possibilities and a default case. If you want to rebuild switch you can do it the closest way like this: if (condition1){
doSomething()1;
}
if (condition2){
doSomething()2;
}
doSomethingDefault();So there is no need (and even no sense) in using else branches and counting brackets. The breaks of the switch instruction can be easily simulated by goto. I wouldn't recomment using loops and breaks for this case as a loop suggests other readers of your code that you want to do somehting totally different.

It's ok as long as you get the control over it. I personally wouldn't use gotos too. But I'd prefer a goto statement to a semi-switch-like construction that requires a loop that is never looped. ;-)
