So how do i set so the knockback system work for damage instead of attack?
Like if my hero gets damaged he will get knockback instead of attacked? is this possible?

 

[Nichilus]

you need damage detection system to correctly catch the "unit takes damage" event

 

[Shanghai]

because i have a spell and i want it to make knockback. mybe its more simple to make the spell itself knockback?

Yes it would be simpler to do that.

 

[Shanghai]

btw is there any system that makes knockback when you throw a spell? GUI

Im after a system that makes knockback when casting spells/damage etc. also when attacking.

 

[deathismyfriend]

All knockbacks can do that. You have to use them to do that.

ok so how do i set it up i have this now.

do i need to add something like if unit gets damaged of this spell type etc?

To activate the knockback you set any spell up like the Example Copy trigger you have.
The Example Copy trigger you have above is what registers the unit to get knocked back. The system then takes over.

i made trigger like this have i missed anything?

 

[deathismyfriend]

I don't think you missed anything but i have never used that knockback system so you will have to check the description on the system more to make sure you didn't miss anything.

 

[Shanghai]

just how do i set up this trigger make knockback when it gets damaged? both those systems r the basicly the same.

 

[Meticulous]

You're using Attacked Unit and Attacking Unit. You need to use Triggering Unit and Damage Source.

 

[Shanghai]

Yes i fixed it but its not working perfectly. When i cast this spell sometimes no knockback. Also if there is à unit or tree behind he gets stoped.

 

[IcemanBo]

Thats because "MoveUnitInsdtantly" does check pathability before it moves the unit.

It may also be kind of bug/error protection.. but if you want to move units without path checking, use SetUnitX/Y.

• Custom script: call SetUnitX(unit, x)
• Custom script: call SetUnitY(unit,y)

If you use the KB2D by Almia or by Bribe, it should bounce to other angle.
