Unit can be killed by particular unit

I want a Farm only be destroyed by a particular Guard Tower. How can I do that in the editor? I am quite new.

If you're using the latest version of the editor, you can do it easily with triggers like so:

• Farm
  • Events
    • Unit - Farm 0000 <gen> Takes damage
  • Conditions
    • (Damage source) Not equal to Guard Tower 0001 <gen>
  • Actions
    • Event Response - Set Damage of Unit Damaged Event to 0.00

It will check any damage dealt to the farm, and if the attacker isn't that specific guard tower, then the damage is nullified

It works perfectly! Thank you!

You can also prevent the attack entirely using this Event, which is most likely all you need:

• Events
  • Unit - A unit is Attacked
• Conditions
  • ((Attacked unit) Equal to Farm 0000 <gen>
  • ((Attacking unit) Not equal to Guard Tower 0001 <gen>
• Actions
  • Unit - Order (Attacking unit) to Stop

But Chaosium's method is nice because it's going to prevent ALL damage which could help in some cases like splash damage or damaging spells.

Combine both for the best results, in my opinion.

If you want every Farm to be immune to this Guard Tower then you need to rely on the Unit-Type Comparison condition:

• Events
  • Unit - A unit is Attacked
• Conditions
  • (Unit-type of (Attacked unit)) Equal to Farm
  • ((Attacking unit) Not equal to Guard Tower 0001 <gen>
• Actions
  • Unit - Order (Attacking unit) to Stop

And if you want every Farm to be immune to every Guard Tower then you can do this:

• Events
  • Unit - A unit is Attacked
• Conditions
  • (Unit-type of (Attacked unit)) Equal to Farm
  • (Unit-type of (Attacking unit)) Equal to Guard Tower
• Actions
  • Unit - Order (Attacking unit) to Stop

These two triggers are more Generic which is often needed if you want things to work for more than 1 unit at a time.
