So I'm creating a dash ability that deals damage across its length and I want the distance traveled to be variable. My issue is creating the targeting region to go along with this (quad is fine).

The guide does not seem to stretch. It has a constant height, equal to the max height of the Quad (from the height field in the quad).

Guide region work as it should across the "horizontal axis"

Guide region does not care about length of the quad

I'm happy to paypal someone $25 USD if they can solve this for me.

Kerrigan's Psionic Shift (Psi Strike) from swarm uses a scaled quad, but no guide region.

Looking through storm game data makes me think this functionality is impossible without Quad Regions from storm (as utilized by Alarak's Deadly Charge).

I've linked the data I'm using for my stretch line quad--though the working part of my region (fixed length) using seemingly the same game data, does not work at all on this sample map. Not sure why, and I don't have the time to debug it :/

Astral shift has a fixed length, and so is its guide region. I'm trying to create a variable-length guide region.

I've attached a new demo map showing the issue with working guides (quad is variable length; the region is fixed length)--the ability in question is using the "Aether Storm" button.

Have you seen this method of cursor position used in Storm?

    &lt;/CActorSite&gt;

 I can use that to do some neat things with quads (effectively replicating vector targeting visuals), but regions (at least the one's we have access to) don't seem to care about launch/impact scaling.

EDIT: why does code block butcher my punctuation?

<RegionFlags index="UseEffectRange" value="0"/> causes the quad's launch site to originate at current mouse position rather than caster position. This does not appear to change how the region behaves (ie region still does not scale with quad).

Alright, I've almost got it working by creating rectangle regions attached to each quad segment actor.  It appears to work for the initial quad creation, but fails on subsequent quad segment creation/destruction.

Further tinkering has found a potential (inelegant) solution of overlapping periodically created and destroyed rectangle regions attached to quad segments.

I'm using query persistent in that gif. Something weird happens and the the position does not seem to update correctly for query persistent-- which is why creating them periodically does work
