SC2Mapster

This is a map that I'm working on primarily to help familliarize myself with the editor, but also to practice making polished, smooth maps and gameplay.

In my map, you move a "Stalker" with WASD, and click on the screen with the RMB to fire a Psi Bullet. You click on the screen with LMB to blink. The Stalker goes through a series of enemies, situations, and a few boss fights to reclaim an ancient Dark Templar artifact.

A few problems I'm having.

-Main Problem: I cannot figure out a way to make the game recognize when a Psi Bullet goes through, or very near an enemy. I want the Psi Bullet to hurt the first target it makes contact with, and then disappear so it doesn't hit any other targets.

-I need a UI that shows the cooldown on the Blink ability

-I need a UI that shows the Stalker's Shields

-Not too important, but if you can set up an Attack Animation that is shown whenever the Stalker fires a bullet, that'd be great. Last time I tried, the Stalker would freeze up on the "stand" animation afterwards, and wouldn't wear off for about two seconds, even if the Stalker was moving. It looked really awkward.
