Sustains with a targeter question

[Micbran]

If I make a sustain with a targeter, I.E. it selects an area and then does an effect on it once you activate it, but the player cancels the targeter by pressing esc. or whatever, would I be able to use forceUseTalent(MyTalent, {no_energy = true}) and then refund the player energy, thus giving them the turn back and turning the sustain off?

Couldn't you just use

Code: Select all

local tg = self:getTalentTarget(t)
local x, y, target = self:getTarget(tg)
if not x or not y or not target then return nil end

in the activate function to prevent it from being turned on without a target?

I wasn't sure if returning nil would prevent it from being turned on, since sustain activate functions usually return a table and not true like action functions do.
