Pre-Heal System

[Endless_Trev]

Hey guys something I've been wondering about, is there a system available that heals a unit of the damage is it about to take, before it takes it? An example is in dota, where a spell makes a unit unkillable for 5 seconds, so if it is on 1 hp, it can still get hit by spells and attacks, it just takes no damage. The only way to work this I see, is to heal for the damage before it occurs, as if the heal occurs after damage is dealt it might not work, i.e if you are on 1 hp, get hit for 100, then healed for 100, you still die.

Tl;dr, is there any pre-heal system available anywhere, I cant seem to find one.

just use the trigger set hp (something) + (something)
And btw pre-heal will also fail
If you are in full life, then you use pre-heal.
It will still be full life yet take damage without any healing
For example max life is 500 then u take 100 damage so its
Pre-heal : 500 + 100 = 500 (due to max life)
Then Damage : 500 - 100 = 400

I can see what you're saying, but I'd rather have a preheal if i can, since someone taking a bit of damage if they're at full hp is not too irritating, however people dying when when they're supposed to be unkillable is well... I'm sure you can see the problem there. So, anyone else got any ideas? I'm assuming the damage detection system by weep can't really be used, as the damage is detected as the unit takes it, so it cant be healed before hand.

Actually set life should work. Because i heard people say before, that triggers work faster and before damage is done, you can try

Wow yeah it works tyvm +rep for sure, I just cant believe it recognises the damage dealt before its dealt o_0

This is basicly how its done:


When unit takes damage, you add some +10000 health ability to it, in order to prevent it from dying. You also save all the needed data about damage dealt and grab the data about damage blocking thingies.

Then you start a 0sec timer, which calls a function, which removes this "death prevention" ability, and modifys units health so that it looks like damage got blocked.

This works because damage is actually taken after the event is triggered. 0 sec timer is used to wait a lil bit, so the damage is actually dealt.

Also you should trigger all your damage effects. For example, you dont wanna run any life steal code for blocked damage, because that damage wasnt really made. ( In DotA for example, you get healed by life stealing, even if damage was blocked, which kinda sucks balls. Do not make the same mistake. )
