• Untitled Trigger 001
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • (Unit-type of (Attacking unit)) Equal to Warden
  • Actions
    • Unit - Order (Attacking unit) to Night Elf Warden - Fan Of Knives

I do not recomend Event Unit - unit is attacked, because its buggy.
You can sit, let your unit start attack animation (if it has attack order already) and spam buttom 'stop'. Your trigger will cause so many knives..

Thats why damage detection systems has been invented.
Use GUI friendly damage detection system.

Its easy to get familiar with, your trigger will look like this:

• Init
  • Events
    • Game - GDD_Event becomes equal to 0.00
  • Conditions
    • GDD_DamageSource Equal to your_unit
  • Actions
    • Unit - Order unit to Night Elf Warden - Fan of Knives

Remember that if given unit does not have ability you want to cast, trigger will do nothing.
You can also use dummies to cast ability, if you do not want that spell to exist on your hero/unit.
To do that method, in actions in trigger above enter:

• Set temp_point = (Position of (GDD_DamageSource)
• Unit - Create 1 dummy for (Owner of (GDD_DamageSource) at temp_point facing Default building facing degress
• Unit - Add your_ability to (Last created unit)
• Unit - Order (Last created unit) to Night Elf Warden - Fan of Knives
• Unit - Add 1.00 generic expiration timer to (Last created unit)
• Custom script: call RemoveLocation(udg_temp_point)

Make sure dummy and your_ability are made properly.

It won't spam if the ability has cooldown like 0.1 second

it would show error messages if the user uses the attack-stop abuse... and its not really a good event especially when the unit is ranged...

thanks for your replies,but what if the units are in group,let say i want it a type of units,watch tower.

For example,i wan every watch tower(type) auto cast fan of knife while attack.

oh,thank you so much,i will try it...=)

 

[Prince_Webby]

Erm...sorry guys but,based on the above example we are using all the ability that existed in the war3 at first.
But what if i want to auto cast a spell which is customized?eg.the spell damage,AOE ect?

Any help plz?

You do exact the same action, the only thing you have to consider is the ability ID - or just basically whats the ability you've based your customized ability on.

So if you used Storm Bolt for creating lets say instant damage spell with other AoE effects you still use action Issue Targetting A Unit with Human - Mountain King - Storm Bolt for your spell.
