/*            -- RELENTLESS --

 Place in the User Defined Event, uncomment the

Attacked and Damaged remarks in the default OnSpawn

script. Be sure to at least double the creature's

hitpoints from the Statistics tab.

*NOTE* To get the burning flame effect you must

create a custom placeable using The large flame visual

effect with a Blueprint resref of 'flamelarge001' and

add the following line to it's onHeartBeat Script:

DestroyObject(OBJECT_SELF,1.0)

Example Relentless Zombies I've made with this code:

Zombie: MaxHP:40 iKnockdown:25 iLightMe:2

Zombie Warrior: MaxHP:60 iKnockdown:30 iLightMe:5

Zombie Dog: MaxHP:25 iKnockdown:15 iLightMe:1

I appreciate any feedback, thanks!

Easily modifiable to turn any creature into an almost unstoppable foe. After the creature takes so much damage it falls down. There it waits and if it is not finished off within the alloted time, it will rise again to continue the attack. The only sure way to silence the monster is to burn it. Put it to the torch or do enough fire damage so it catches fire. Modify the the resistances and you can have a water elemental that can dispatched only by freezing it with Cold, or a vampire that must be Staked through the heart.

Let me know if you use it or if you find any modifications that help the code. This is my first published code, and it was a great learning experience, have fun!
