Code:
Name: 'IF Example', VNum: [ 22], RNum: [ 22]
Trigger Intended Assignment: Mobiles
Trigger Type: Greet , Numeric Arg: 100, Arg list: None
Commands:
* By Rumble & Relsqui of The Builder Academy tbamud.com 9091
* First we set %anumber% to some number between 1 and 100.
eval anumber %random.100%
* Then the beginning of the if-block.
if %anumber% == 5
* The following commands are only executed if the above condition is true.
* That is, if %anumber% is equal to 5.
clap
say It's your lucky day!
say You picked my favorite number!
* If those commands were executed, the program skips to the next end.
* Otherwise, it looks for an elseif.
elseif %anumber% > 90
* To read the following commands, the program must have determined the
* following: The first condition %anumber% == 5 is false.
* The second condition %anumber% > 90 is true.
emote shrinks down to the size of a mouse.
say Squeak squeak squeak!
* If the first elseif condition was also false, the program looks for the
* next one.
elseif %anumber% < 10
* Here's a tricky one. If %anumber% equals 5, the program will already have
* run the commands immediately after the if-statement at the top. Therefore,
* the following commands only run when: %anumber% is not five (failing the
* first check) %anumber% is not greater than 90 (failing the second check)
* %anumber% is less than 10 (passing the third check.)
emote grows an elephant's nose.
emote blows a mighty blast with %self.hisher% trunk.
* And now, the default, when %anumber% fails all the above checks.
else
* Note that else has no condition.
emote disappears in a cloud of blue smoke.
%purge% %self%
* For that to happen, all of this must be true: %anumber% is not five.
* %anumber% is not greater than 90. %anumber% is not less than 10. If all
* those conditions are met, the mob will disappear in a cloud of blue smoke.
* Finally, please don't forget the all-important...
end
* Ends are good. They tell the program when the if-block is over. After any of
* the above sets of commands runs, the program skips to the next end.
*
* We could have omitted the else. If we had, and none of the conditions had
* been met, no commands in the if-block would run. However, there can never be
* more than one else. There is only one default. There must always be the same
* number of if's and end's. We could have had any number of ifelses, from zero
* on up. To summarize, here is the basic format of an if-block:
* if (condition)
* (commands)
* elseif (condition) <---optional. 0 or more
* (commands)
* else <---optional. 1 or 0
* (commands)
* end
*
* So the simplest possible if-block would be:
* if (condition)
* (commands)
* end
for TBA.
