[Spell] Backstab

[Synergy]

Hi! I'm wondering if someone can make me a spell for my vocation "Rogue"

When you use the spell
example:

JaySwag: Backstab!

Boom, You are suddenly behind the target (teleporting or whatever) and you hit him with a hard strike


Is this possible?

it's getPlayerLookDir

I can do this script for you, for free so no more trollin' here... -.-

possible without compiling and source edit.

 

[Cykotitan]

just merge the spells, no need for doPlayerCastSpell

no need for 'if' statements. not sure of the 'true' I believe it should be 'false'.

Thanks for feedback

Its wokring like charm, but the problem is that it should be like this, it going to teleport to target on the closetfreetile no just behind :/ because i want add damage on it. when player is close to the target it says something is blocking.

Please make it so you can get tped to any closetile around the target.

Backstab is not what you just said. Backstab is stabbing from BEHIND, go get the omnislash spell then.

That's even more easier but I got that idea first so, I wont release it xd
With "easier" I mean, you can do it aswell ...
