Evasion and distance

Drakonaut · Jun 18, 2014

Hi guys! Is there a way where as the distance between 2 units increases, the evasion of both units, when attacking each other, increases?

E.g. A to B is about 500/1000/1500 range -- 10%/15%/20% evasion

EDIT: I mean like linear/exponential increase in evasion, not a locked increase in percentage.

Thank you!

Well, two ways.

Either you use Evasion ability and give it to the units via Spellbook, so that it doesn't show up (and look like it's game mechanics), then calculate the distance between the units' locations, convert that distance from real to integer and through a formula increase or decrease the level of Evasion for both units.

Otherwise, you could code the evasion effect yourself, by using a damage detection system. Once damage is received, use a formula based on their distance and generate the % chance of dodging the damage (by dodging it means that you would have to heal the damaged target for the damage dealt). However, this is a bit more complicated, since you need to distinguish the damage originating from regular attacks only and not spells or abilities.

Therefore, you could have something like LevelOfAbility = (Integer((Distance between Point1 and Point2)/500)).

If 2 oncoming projectiles are attacking the unit, wouldn't method 1 not work? I mean that there is a possibility that the attacked unit was attacked by 5-6 projectiles simultaneously. Hence only method 2 is feasible in this case?

Sorry if I didn't make it clearer. Thanks for quick reply!

in case of ranged units with projectiles both methods are rather exploitable, because even when you check the distance with Damage Detection System, you can only check the distance of units when the damage is landed, not when you launch the missile.

This problem is however almost impossible to evade, unless you use something like predicting with Unit - A unit is Attacked or Unit - A unit Attacks unit(I dont know if this even exists) and then wait for the damage instance to land on unit and then calculate the distance stored in some hashtable for the unit when it was attacking and the unit that was attacked when the damage landed. Otherwise I could just launch a projectile and run away, maybe leap with some spell or teleport, and you would not hit anything with both methods

Detecting damage type is "easy" if you use Looking_for_help's damage detection system, and dont worry if you dont know vJass/Jass, it has GUI counterpart.

soo this works but only if you trigger it. if you add the evasio per spellbook to the units you have to heck more like anything else and you have to make 100000000000000000000 evasions with every value.

if you want then i can trigger it for you. well im just doing it right now
wait me for edit this post

Well it should work to check the distance with "a unit is attacked" and then see if the attack was interrupted or not, if it were not then when the damage is dealt you do the evasion roll.

well yea I wrote that, but maybe quite cryptically

Timo · Jun 18, 2014

well here we go
hope its okay for you that i made the evasion with this calculation of course you can change it if you think its to high/low
btw i hope the code is correct and works fine xD
edit: wel just testet it, it works perfect

sorry to disappoint you, but this is terrible. You want to know why?

because:

Unit Group - Pick every unit in Evasion_Unitgroup and do (Actions)
- Loop - Actions
  - -------- -- --------
  - Trigger - Add to Damage Take <gen> the event (Unit - (Picked unit) Takes damage)
  - -------- -- --------

and

Init 2
- Events
  - Unit - A unit enters (Playable map area)
- Conditions
- Actions
  - Trigger - Add to Damage Take <gen> the event (Unit - (Triggering unit) Takes damage)

Just never try to write this, just pick up DDS from this website and go with it. Do you think we would need such complicated systems if it was so easy to do such a thing? Obviously not

Timo · Jun 18, 2014

hmmmm DDS... i thought it wasnt necessary here. well nevermind

then he should use the DDS.
just send him your pro dds system, becasue i dont know which you mean he should use..

When you keep adding an event to a trigger it will eventually crash the map. Only so many events can be associated with a single trigger.

realy? i didnt know that, what do you mean with crash? you mean critical error or a freeze?

Actually, a bit off topic, considering that there's a function to add events to a trigger it's a bit weird that you can't remove events. I mean I think you could basically make it work like with any indexing if there was one or if you could make the function in jass.

Actually I'm not sure how severe it is to be honest. But an added event cannot be removed again. So if a ton of units die all the events for those units will take up memory.

Here is a link with some pointers.

I wanted to do this a very long time ago. This is impossible to do without an atrack indexer. Currently, there are no attack indexers, so you're stuck. Luckily, attack indexing was recently solved, so someone just has to write one.

Timo · Jun 18, 2014

i did this with 43 triggers for my spells and item effects ..... (a unit enters the map, add to the trigegr the event, trigegring unit gets damage)
i think i found my probelm of my map freeze?

can you show me the best dds atm out there? for me and Drakonaut
so Drakonaut can use it too for the trigger i made.

is it this? http://www.hiveworkshop.com/forums/...1-1-0-0-a-231846/?prev=search=dds&d=list&r=20

I have actually never used a DDS myself.
But I have heard this mentioned plenty of times:
http://www.hiveworkshop.com/forums/...earch=Damage%20detection%20system&d=list&r=20

And the one you linked yourself is supposed to be really good as well.
I don't know what the difference is though.

The reason people use Weeps is because it lets you use two different DDS system, itself and the GDD. However weeps does not let you detect if the damage is from an attack, spell or trigger which the physical DDS do and that is pretty neat.

Wow...this system is harder than I thought. But thanks for the help guys!
