[Spell] Base abilities that cannot be cast when unit is already affected by it?

[Ugabunda]

Hi guys,

I want to make a spell which cannot be cast on a unit, if the unit is already affected by the spell. I could probably add this condition via trigger, but I figure it's more efficient if I use a default ability in WC3 which cannot be cast on a target, if the target is already affected by the spell.

The only problem is... are there such abilities? Google didn't help and I don't know any spells that behave like this from the top of my head.

Cheers!

I don't see the issue with using triggers. Pretty simple and bug free to do something like this:

• Slow Example
  • Events
    • Unit - A unit Is issued an order targeting an object
  • Conditions
    • (Issued order) Equal to (Order(slow))
    • ((Target unit of issued order) has buff Slow) Equal to True
  • Actions
    • Unit - Order (Triggering unit) to Stop.

Also, and I didn't test this, but you could probably change the Stop order to instead Order the caster to use a hidden ability that throws an Error.

Thanks you two!

@Uncle : I thought about giving a stop order + sound effect. But a hidden ability which displays an error would ofc be better. What hidden ability would do that though?

I'm not sure if it even works this way, but wouldn't an ability with it's Targets Allowed set to None always give an error? Or maybe set it so it can only target Suicidal units or some classification that you'll never use.

Then you could even edit the Error text in the Gameplay Interface to have a proper Error message.
