[Solved] Rain of Frost Arrows

[Lordul Dracula]

Hello everyone I made this skill Rain of Ice Arrows(I used Cluster Rockets to make this skill) and I want to add a cold effect for this skill. Is there a way to use Frost nova? Because i want to avoid to use a group event or an every 1 sec event. This skill is for a basic unit - the first range unit from this race. Thx +rep

You could spawn a dummy caster at the target location of the spell and have it used a custom version of Slam or something like that to create a slow debuff. Units wouldn't have the blueish tint like with an actual frosty effect but heh at least it's pretty lightweight

 

[Pyrogasm]

Better: spawn 2 dummies and cast frost nova on one of them to get the aoe slow on everything else.
Best: spawn 1 dummy and have it frost nova itself to get the aoe slow on everything else.

Better: dummy cast blizzard in the area with no spell effects during the arrow rain.

I tries this but is not working ...of

 

[Chaosium]

Make sure there isn't a little something that prevents your dummy from casting the spell, for instance a spell that costs mana but the dummy has 0 mana, a spell that cannot be cast on specific targets, an invulnerable dummy, etc.

 

[Pyrogasm]

They probably can’t target each other because they’re invulnerable or something. Try removing all abilities from the dummies and/or giving them a model so you can see what’s happening.

The first one doesn’t have an expiration timer set, so if the nova doesn’t kill it that dummy will exist forever

I found the problem is because of the dummy, air unit. But is there a better way to to make this instead of making 2 dummys?
Update like this is working now

How about ordering a Dummy unit to cast Earthquake at the target point. You don't get the blue tint but I think that's a fine compromise. Then use a Unit Indexer to link the Dummy unit to the Caster and simply Remove the Dummy once the Caster stops casting Rain of Frost Arrows. Or if you know that each Player can only have one hero that uses Rain of Frost Arrows at a time you can avoid the Unit Indexer and simply use the caster's Player Number.

Why earthquake when you can use blizzard to get the blue? The dummy should be able to nova itself if set up properly. Dummies also shouldn’t have to be air units.

I don't think Blizzard slows or applies the blue tint but maybe I'm wrong.

And if the Dummy has the Locust ability it cannot be targeted by Frost Nova.

 

[Pyrogasm]

You’re totally right, slowing blizzard is a mage talent in WoW classic not a wc3 archmage ability. I’m cooked.

This skill is for a basic unit not for a hero and maybe is better if the dummy will use a skill that will apply the effect for a period of time that a skill like Earthquake. A solution for that can be Slam (what Chaosium suggested in his first post). Is the way I did it wrong?? Also if I'm not wrong Earthquake is hard coded because i tried to use this skill for something else but the buff can't be changed or something like that.

Can you show me how to order a unit to target itself?

Also thx for your help so far Pyrogasm,Chaosium and Uncle

You make a unit target itself the same way you make a unit target another unit. The problem is that you 1) Cannot target units with the Locust ability. 2) Need to make sure Frost Nova has the correct Targets Allowed. If both of those are setup properly then it will work fine.

The reason for Earthquake is because Cluster Rockets fires the projectiles over the course of the spell. If you simply Slam once at the start of the spell it won't really perform the way I assume you'd want. But it's your call, Slam is easier to work with. You can also order the Dummy unit to cast Frost Nova on each nearby enemy unit within the Cluster Rocket's AoE, and simply set the Frost Nova AoE to 0.

If you wanted my method to work for multiple units owned by the same player (MUI) you would simply change (Player number of (Triggering player)) to the (Custom value of (Triggering unit)). Of course, you need a Unit Indexer imported into your map so that Custom Value can be used this way.

Earthquake is not good is hard coded i just tested again this skill. I wanted to make a skill using this skill and it doesn't work well. If you edit the buff for this skill will still show the basic one .

Another method would be to use Unit Indexing or Dynamic Indexing and repeat the Slam effects periodically. There's a tutorial for these in my signature.

Or you could even just give your Dummy unit X Life where X is the number of times you want it to cast Slam:

• Events
  • Unit - A unit Starts the effect of an ability
• Conditions
  • (Ability being cast) Equal to Slam (Dummy)
• Actions
  • Wait 0.20 seconds
  • Unit - Set Life of (Triggering unit) to (Life of (Triggering unit)) - 1)
  • Unit - Order (Triggering unit) to Slam

This would make the Dummy cast Slam every ~0.20 seconds until it kills itself. Waits are less than ideal though.

Yeah this could work but what about my trigger is bad or i can keep that trigger too?

It doesn't leak and I assume you tested it so I guess it's fine.

The only thing I don't like is the idea of having a vulnerable Dummy unit that's used as the target for Frost Nova. What's stopping other triggers/spells/units from interacting with it?

I set the life for that dummy to 99999 hp and is for neutral passive

 

[Pyrogasm]

In theory it kills itself instantly so it would only ever matter for 'enters range' events. The unit could have locust by default and then have it pseudo-removed to target itself, probably. Hide unit, remove 'Aloc', unhide unit.
