I've seen these in a few maps and I have been so far been unable to create a shockwave, that pushes all the units around the user in a full circle.

Is it using force or an invisible projectile?

You could:
a) Look at an example .odf (I'm almost positive that there are something like 5 different versions of a force wave floating around somewhere; I know for sure there's one in one of my released assets), or
b) Add that it. ConeAngle sets the radius of an emitterordnance. Emitterordnances - used for countless force powers and other weapons all the time - are basically like big conical (or spherical, depending on how you set it up) wavefronts. You know what the sonic blaster looks like (this is actually not really an emitterordnance, it's a fatray, but it can be used for demonstration) - that's basically a really small cone emitted out in front of you for a certain distance. That's all emitterordnances are, but in the case of things like force push or pull or wave, they're invisible.

Yeah, I tried that but it didn't work too well. Then again, it is me.


I'll try again.

Force push tends to work badly against droids (no idea why) and sometimes doesn't work too well. So, two ideas:

1) you could keep trying yourself till you get something you like.
2) You can cheat. Make a force wave that uses no emitter ordnance at all, but instead creates an explosion instantly. Add in the line:
HurtOwner = "0"
And the line:
PushDeadOnly = "0"
and play around with the push values, and you have a working force wave that will push anyone in range (unless they're behind an object, same thing applies to emitterordnances though).

Also, with EmitterOrdnance you have to set the max amount of targets to be hit by it.

MaxTargets = "10"

Is the common one used in Force push. Once I set ConeAngle to 90, and MaxTargets to 40 and made the Imperial Team Large. The results of hitting them with a beefed up push were quite amusing.
