Looking for GOOD Shield

[Leazy]

Hello!

I'm looking for a good shield spell. A spell that shields the unit, protecting it from X amount of damage over X sec, with X buff (unit loses X buff, unit loses shield) and with X special effect. Shield should not be castable on targets with Y buff. (Pretty much exactly like the WoW Priest spell Power Word: Shield.

+rep if you can tip me of some spell like this/make me one/modify one already existing for my needs. You will also receive credit in my map, for what it's worth

Description:
- A JESP spell that allows the hero to cast a shield on a not Ud ally or on an Ud enemy (just like Holy Light). The shield will absorb an amount of damage for the allied unit thus protecting it from harm, or it will amplify the damage caused to the unit if it is enemy. When the shield dies, the shield unit will get healed by the remaining energies of the shield if it is an ally, or it will be damage by the remaining energies if it is an enemy.

Sounds intresting :thup:

Sounds like a good idea of a spell, but when I attacked the shielded unit, it still took damage, and I don't want that heal-when-the-shield-dies things, nor the undead things. And it requires like 10 systems, that's a little heavy for my taste. I'm looking for something really simple that does what I need only, maybe some other features, but this system is too much in my taste. Thanks though and +rep.

I am glad that I could help you even though you weren't inneed of such a spell. +rep

I've spent a lot of time trying to figure out a good way to do this with simple triggers lately. I ended up with a bit of a clunky outcome, but it seems to work decently.

I didn't want a spell that healed after damage was taken, so I ended up just making the target invulnerable and creating a dummy unit with the amount of HP that I wanted to shield that moved to the position of the target every .05 seconds.

When the shield dies, I made the target vulnerable again.

The problem I had with this though was that it would cause monsters to simply run away rather than attack the shield to destroy it, so I did three* things.

1) added an attack to the shield that did 1 damage, with no cooldown.
2) added a trigger that ordered the shield to attack a random unit in 500 AOE every .05 seconds.
3) added a trigger that, if random number between 0 and 1 was greater* than the distance from the shield to its target divided by 700, it was ordered to attack the shield. (This made it so the further the unit was from the shield, the less likely it would be ordered to attack it.

All of this together seems to have worked out nicely for me. I'd post the triggers but sadly I'm at work.

 

[Leazy]

Hmm, thanks for the help, but I don't want units ordered to attack etc. I think that can make pretty many bugs in the future.

 

[inclinedplai]

Hmmm... Does the Hardened Skin ability reduce damage from spells too? I was wondering if this ability could be given to the shielded unit for the duration...

Obviously I'm really interested in this type of spell too ... Just brainstorming. I like problem solving.

 

[Executor]

No, the "Hardened Skin" ability just reduces physical damage.

If you would just want a "shield" wich blocks ALL damage over a period of time this spell would be rather simple, but if you want to assign the maximum amount of blocked damage you must react on the "takes damage" events and this is kinda more work.

 

[Leazy]

I could use the undead nerubian heroes armor skill, it can reduce damage (spell, attack, everything), but how would I keep count on the damage taken and make it MUI? Also, I think the damage taken would be 0 with that skill, so counting it would be kinda hard.

 

[Executor]

y, as i said this "amount" parameter is much more work.
Are you able to code in Jass?
Because in Jass this whole spell woulld be rather simple..

 

[Leazy]

No, I can't code in jass, that's pretty much why I'm asking for help

I have seen that system before, but each time I import it and test it I get windows error message saying that world editor must shut down. How can I fix this? / Do you know any other system?

I do have the game cache variable called ''hasch''.

I made a pretty crappy written Power Word - Shield Trigger.

Problems:
- Units take damage before Shield can truly protect them, meaning if they take a killing blow hit but they have a shield up, shield wont do anything.
- Stopping the unit from casting power word shield if the unit has a buff. My method works but its not that "great." Should add like an error saying the unit has a Power Word Shield debuff.
- Biggest hurdle for me was the Damage Detection. Its messy and not good enough but it works XD

Huge thanks for trying, but I could do that trigger myself, I really need the shield to protect damage before it's dealt. +rep though

 

[deebee]

Hmm, is that even possible? I Mean to detect and stop the damage before it even occurs? XD

 

[Leazy]

Yes it is

 

[Weep]

WC3 already has a shield spell: Anti-Magic Shell. It only blocks spell/magic damage, though, so we have to convert any damage to spell damage. I think this should do what you want...
