13 Nov 2011 Bribe: Looks solid. Nice work on the spell. Approved. One last thing - "99999" for unit facing speed is the same as "1" I'm afraid. It doesn't go faster than 1.

Is there any way to import this spell to my map and avoid compile errors like this one?

@Nubius Is JassHelper and vJASS enabled? There should be a menu in the trigger editor named JassHelper, where you can enabled them in the dropdown menu.

Thank you very much for fast reply!

Yeah, both functions are enabled. Nevertheless, I get errors even when I try to press "Save" on the original sample map.

Disable vJASS but keep JassHelper enabled and see if you get the errors again. World Editor on patch 1.31 had a problem with how it integrated JassHelper, so disabling vJASS is actually enabling it.

This is not the case for Reforged World Editor though.

Unfortunately, it seems like there is no difference in logs.

Well, if neither option gets rid of the errors, then your Warcraft 3 installment might just be busted up. I suggest reinstalling Warcraft 3 1.31 from Wc3 Download Archive and see if the problem persists. You will need the cd-key for at least ROC.

On my end, everything is working fine with or without vJASS enabled. I just tested by downloading this spell and saving the map. The map was saved without errors. I got my 1.31 version from there as well.

Thank you for your help!

I feel very stupid about it, but I've just tried to launch Reforged editor just to test saving the map. It worked, but now my 1.31.1 editor is not launching because of "Not enough memory resources".

Deleting reforged, reinstalling 1.31.1 didn't help. Seems like there is something in the register entries.

I hope I'll find the solution tomorrow. Don't want to migrate to reforged :(
----------------------UPDATE--------------------------
Well, solution is found. To tell the truth, I'm not sure what exactly have I done, but:
1. "Not enough memory resources" issue is DEFINATELY solved via deleting and recreating proper registry entries.
2. My WC3 version was messed up too so downloading new client from given link helped to solve initial problem. Thank you again! +rep
----------------------UPDATE2---------------------
I've forgotten to tell my thoughts about the spell itself. It's freaknig amazing! Its visual effect fits perfectly to the Blademaster model.

I had to make 2 changes though:
1. remove damage from the spell, because it was the teleport dealing damage to the target, not the attack.
2. when effect starts, I now give my blademaster a special bash ablity for a short period of time. This ability buff (stun) and simple DDS allow me to apply additional damage to the "after-teleport-attack" and then I remove the buff and the ability.

Sorry for my english.
