decipehering jass problem

11-10-2006, 04:52 AM

OK here is my problem, I found a jass trigger for jumping but it has excess code(I can see somthing about towers...) in it and i dont know where to begin. I am jass illiterate and i need to know what parts are required and which parts are not, also i need to know what to change to make it relevant to my map aka variables.(Switch $$$ with %%%)(Create &&&) Basicly i want to be able to jump (never to higher ground) and get hurt / slowed when falling from too high.
Thanks in advance, I really appreciate it.

PipeDream	Nice to see people reusing code from Aftermath. You need variables for each udg_* and you need Kattana's attached var script from wc3jass. Then you need to learn JASS and understand the code so that you're able to maintain it.

Thank you for replying, but i am still quite clueless. I obtained kattanas local handle variables script(I think thats what you ment by attached var script), I also made the "Seconds" and "JumpLimit" INT variables as you advised.

I wasnt told however which parts of the code are irrelevant and how to make it work. Obviously it is my lack of jass knowledge that is preventing it from working (I am just starting to learn about the basics). If you could point me in the right direction again it would be very helpful. Giving me the anwser would be nice as well. : P (As much as you want me to learn jass it doesnt happen in a day, nor will i know jass by solving this problem, I will learn just as much if i saw the correct version and looked the differences)

Again, Thank you for replying, it helps so much.

Almost got it to Work except one part where it "expected a"(". and 2 missing endif's (which are there...i suspect it has somthing to do with the first problem)
