Switch: Difference between revisions

Latest revision as of 00:16, 12 September 2021

The switch statement in CON is similar to that in C.

 switch <gamevar>
   case <constant>
     <do something>
   break
   case <constant>
     <do something>
   break
   default
     <do something>
   break
 endswitch

The case keyword works like an ifvare statement, and default operates on every possibility that is not specified by a case statement. Each case block must be terminated with a break statement.

-Caution:  ''Nested switches do not work because of the way the CON compiler compiles them''. A workaround is to put the nested switch in a seperate state, and call that state from inside the first switch.
-Also, putting extra [[break]] statements inside a case argument will cause a lot of errors. Again, the workaround is to put the commands that need to be seperated in another state, along with the break.
