(@solved - %confused) confused on where to use %eval
|
in zmud part of an alias was:
| Code: |
#MATH quest_time (%secs - @quest_start_time)/1000
#IF (@quest_time > 59) {
#MATH quest_minute_time {@quest_time/60}
#MATH quest_leftover_time {@quest_minute_time*60}
#MATH quest_second_time {@quest_time-@quest_leftover_time}
} {quest_second_time = @quest_time}
|
to make it at least work in cmud it is now...
| Code: |
quest_time = %eval((%secs - @quest_start_time) / 1000)
#IF (@quest_time > 59) {
quest_minute_time = %eval(@quest_time / 60)
quest_leftover_time = %eval(@quest_minute_time * 60)
quest_second_time = %eval(@quest_time - @quest_leftover_time)
} {quest_second_time = @quest_time}
|
the 1st line is where i was having an issue... changed em all to eval anyways... it at least works now
the help file says only use %eval if you know you need to... how would i know? |

You should be able to get rid of "%eval" in every single one of those lines. Just leave the parentheses.
The way you know you need to use it is if you can't get it to work without %eval. But "((%secs - @quest_start_time) / 1000)" works fine. For mathematical equations, all you need to do is make sure the entire thing is inside parentheses.
| Code: |
quest_time = ((%secs - @quest_start_time) / 1000)
#IF (@quest_time > 59) {
quest_minute_time = (@quest_time / 60)
quest_leftover_time = (@quest_minute_time * 60)
quest_second_time = (@quest_time - @quest_leftover_time)
} {quest_second_time = @quest_time}

As Rahab said, I just want to say it in hopefully more succinct terms:
If you can use the expression without an error, you don't need %eval. If you get an error using an expression somewhere, you need %eval. |
