Dammit, I misundersttod. I though that you wanted an ability of a multi-membered squad, NOT to affect any (possibly) attached commander.
But you simply want the ability of the commander, NOT to affect the squad he may be attached to!!!
In this case things are very easy. No ticks required.
>> So, go into the ability, in the area_affect/area_effect_information, and set the area_type to tp_area_effect_point.
And then in the modifiers ability confers (like the health regeneration modifier you are after, or ANYONE other modifier you want), set the application_type to tp_mod_apply_to_entity.
Thank you.I also realize that i could just raise the natural health regen of such unit.Silly me
