Ability: Firewall

[Klasus]

I'm working on an ability which creates a wall of fire, units standing in the wall of fire take damage over time. I know that this can be done in diffrent ways. It can be done by dummy having dummy units forming a wall, units close to the dummy units will take damage. It's not very efficient though. I want it to be like using High Templar - Psionic Storms at a few points, forming a line. Units standing in the storms will take damage. I'm wondering how I can create these storms without ordering units to use Psionic Storms at the points. Do I have to create effects at points from players? If so, which effects? I know that there are several Psionic Storm effects.

You use an offset effect (like the effect used by the banshees with screemer missles) to create many psyonic storm effects.

Ok, but let's say that I want to create one psi storm, how do I do that?

 

[Dr Super Good]

By chaining various effect class entries together like used by the High Templar.

 

[Klasus]

Do you mean creating a trigger with actions that are all the effects used when using the ability in the right order? would it be efficient or inefficient to create a hidden unit which uses the psi storm at the points?

 

[Dr Super Good]

Look at how psyonic storm is done and add that to many offsets using the appropiate effect. No triggers involved.

 

[Klasus]

Is it the persistent effect that needs to be moved? how do I create several persistent effects for one ability? how do I make the ability have several actors placed with offset? I don't know much about effects or editing the mechanics of abilities, are there any good guides for this?
