That should work i think. I've highlighted what i added with a big arrow.


Yep it's working. Thanks. I kinda had the same command but in the wrong place.

Offtopic: are there any tutorials out there on getting into jass?


Minecraft. :D

Is it possible to use this, but instead have the location in front of the caster at X distance? I'm trying to create a leap spell, but it is instant cast with no target. How would I do this?


Change can be a good thing

polar project out from the caster along its facing angle and use that as the target location

    Wow spring time in Japan is awesome. Enjoy!
  • The Helper The Helper:
    Hopefully it will be more pleasure than work
  • vypur85 vypur85:
    Recently tried out ChatGPT about WE triggering. Wow it's capable of giving a somewhat legitimate response.
  • The Helper The Helper:
    I am sure it has read all the info on the forums here
  • The Helper The Helper:
    i think triggering is just scripting and chatgpt is real good at code
  • vypur85 vypur85:
    Yeah I suppose so. It's interesting how it can explain in so much detail.
  • vypur85 vypur85:
    But yet it won't work.
  • The Helper The Helper:
    it does a bad ass job doing excel vba code it has leveled me up at my job when I deal with excel that is for sure
  • vypur85 vypur85:
    Nice! I love Excel coding as well. Has always been using Google to help me. Maybe I'll use ChatGPT next time when I need it.
  • The Helper The Helper:
    yeah whatever it puts out even if it is not perfect I can fix it and the latest version of chatgpt can create websites from pictures it will not be long until it can do that with almost all the tools
  • The Helper The Helper:
    These new Chat AI programs are going to change everything everyone better Buckle the Fuck Up!

    A lot more low quality content, a lot more half-baked stuff.
  • jonas jonas:
    If you're good enough to spot the mistakes of the answers you don't need it in the first place. If you aren't good enough, you're gonna rely on some half-correct stuff
  • The Helper The Helper:
    the earlier AI is and has been used extensively for publishing news and other content for a while now
  • jonas jonas:
    I used to be active on quora, it's now flooded with extremely similar, superficial answers that often miss the point of the question
