Nucular strike is channeled
Infestors "mind control"(can't think of name) is channeled(I think)
The first one might be easier to modify for a untargeted ability
While the 250 cannon strike would be your best bet for a channeling unit targeted ability
You missunderstand me, I'm looking for a target point spell, or a spell like channel (in which you can modify if it's unit/point target or instant etc)
Dito, any of the objects in Core.SC2Mod are pretty much effectless (they are the framework of all the implemented objects). Take a look at CAbilEffectInstant and CAbilEffectTarget.
I, however, personally recommend you to try to implement your spells using the data-editor first before attempting to trigger them, just for the sake of versatility.
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
