2D shoot in direction where mouse is

Hello! First at all thanks for your time and help. I am very new with Unreal Engine, so maybe my questions are pretty simple.

Well, here we go. I want that my character shoot in the direction where my Mouse is (or right game pad axis is). I guess this should is pretty simple, but I can’t figure how to do it. I tryed find tutorials, but they were for set potency depending where mouse was, and I want that my potency is always the same.

After some trys and look some webs I did this:

It is pretty simple (it don’t even shot in other direction).

I tryed set Mouse Location as Impulse and it didn’t work.
I tryed ACOSd in order to get grades, but I didn’t figure how use it later.
I tryed even use 2 impulse at location, one first for first location (with low velocity) and the next one using mouse, but it didn’t work neither.

And at this point I am totally out of ideas.

thanks for your help and patiente! Really!

I found the answer in this video: A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums
