I want to make a skill but it doesn't work

I wanted to make a skill called Fire and Ice- its based on crushing wave but i cant get to different missile models to work only one works at a time is there a way to do this
please and thank you

I'm pretty sure Crushing Wave only supports one missile.

I see thank you please make a tutorial if you can

A tutorial on what? Making a double missile crushing wave?

Just use a dummy caster. If you're unsure how to do that, there are already tutorials on this site.

This is an easy one.

Make your hero cast "Ice and Fire". Make it based off of crushing wave, and give it your ice missile. Make it deal half the damage the whole spell should do.

Now make a dummy caster at the point of your hero. Make a spell exactly like the hero one, except in dummy form (no mana cost, no cooldown, etc. etc.) and with the fire missile. Have your dummy caster cast the dummy spell at the same point the hero casted his spell.

If you did everything right, your spell should work. (Unless I explained something wrong, but I don't think I did.)

how do you make a dummy caster and such im somewhat new to these things

You read this comic: http://www.ctrlaltdel-online.com/comic.php?d=20070205

Then you search "dummy caster" on the forums :)

Okay, dummy caster is easy.

It's a unit (any will do, but basing it off a wisp is easiest.)

1: Give it the Invulnerable (neutral) and Locust abilities.
2: Give it 9999999 HP and 999999 Mana
3: Under "Art - Model File " put "none.mdl" into the custom path box.
4: Make sure its food cost is 0.
5: Make its sight range 0, both day and night
6: Remove it's Unit Classification (if basing off of wisp or a worker unit)
7: Make the following fields 0.00:

• Art-Blend Time
• Art-Cast Backswing

8: Set it's defense to 9999

You now have a dummy caster. To use it, create it through triggers at the point of your caster (or target, or whatever), give it your dummy ability through triggers, level it up through triggers again, then order the dummy unit to cast the spell using the appropriate function (IssueTargetOrder, IssuePointOrder, IssueImmediateOrder).

Obligatory CAD rule. I couldn't be bothered with all the text unfortunately.

thx ill try it as soon as i can

BAsecly it's better if the caster's (or the dummy's) spell does all the dmg cause if the target has some spell dmg re4duction buff/skilld or whatever then it would mess up the amount of dmg that will be inflicted.

No it won't.

Say a unit has 25% spell reduction, you want the skill to deal 200 damage. The first wave deals 100 damage, due to the reduction it will deal 75 damage. The second wave also deals 100 damage, but because of spell resistance it also deals 75 damage. Dealing a total of 150 damage.

Now if 1 wave deals 200 damage, due to spell reduction it will also deal 150 damage.

Why does the Dummy Caster need 9999999 hp and armor when it has "Invulnerable (neutral)"?

In case of the every so odd situation you might consider things that break regular targeting.
