smoke-with-trigger action_delay, on_death

[Ranakastrasz]

action_delay: Allow the some-with-trigger to not immediately call it's action, but wait x ticks before the first one.
on_death: After duration runs out/smoke dissipates. - Make sure it works even if action is not set, which currently appears to cause the smoke to just disappear instantly.

For something like delayed explosions or something - Nuclear bomb with a 5 second timer, etc.

The cannon-projectile has a final_action Is this something that would do what you want?

No, it needs to be an immobile entity. Well, that might work. Don't think I tried it yet.
