Saving Values into the Stack The Stack can be used as a means to save a value than retrieve it whenever necessary. The new dup operator allows the number to stay in the Stack continously
cond *.robage 0 = start 998 rnd 1 add stopcond *.refeye *.myeye != *.eye5 50 > start dup .tie store stop
This will duplicate the value and also use it to tie. The same value can then be kept and re-used forever. To use it as part of a condition statement requires a solo "dup" gene.
Timing Actions with the Stack Another more advanced use is to store a whole series of actions into the stack and then unstacking them in the following cycles.
cond *.robage 0 = start 50 .repro 314 .aimdx 10 .up stop cond start dup stop cond 0 > ' dup gene and 0 > not really needed in this case but helps to ' demo ability to sense the stack without destroying the information start store stop
This will cause the bot to perform the above actions from bottom to top. This could also be used for anything from MB reproduction to more accurate aiming.
The stack no longer carries values between cycles, making many of these techniques less useful than they were previously.
