I went through this tutorial once for time warp, as I was trying to add a very similar ability (an aoe slow for enemies) and I couldn't get it to work. I was trying to add the ability to the Nexus instead of the High Templar. So I went through it again, and when I put it on the Templar it works perfectly...but I moved it over to the Nexus and it still didn't work. Does anyone know why it wont work on the nexus? I get the button, I can press the button, then I get the cursor...but when you select the place to cast it nothing happens. No energy gets used, nothing. I am using it within range as well in case anyone was curious.
Thanks for any help.
tldr: Why can't I use Time Warp with the Nexus?
Edit* I found the solution to the problem. The Arc setting in the Ability needs to be 360 because the building cannot turn.
Your tutorial helped me a lot, but I have to say that the Electric Shock is casted in templar's feet, instead of in him hands. I lent to make an animation of attack but can't make ability to cast in hands.
