Custom spell for an npc?

[Drazhar]

So I downloaded a Chain Hook spell, which pretty much drags a unit around dealing it damage. However, I want an npc to use it, but they wont as it's the channel spell. I'm not sure how to make a trigger so that it'll use it. I tried giving it the curse spell and just setting all of the data to 0 so it has no effect, but whenever it casts curse, order it to use the spell on the target curse was cast on, and I changed the order string of the spell to impale, but it still does not seem to work. here's the link to the spell I used, perhaps there's a different one which would better suit what im after?http://www.thehelper.net/forums/showthread.php?t=119550

You cannot effectively edit the order string of an ability. It keeps the one it originally had, so it depends on which ability it was based off.

The channel spell however is an exception, there you got an extra field "base order id" (DataFX/Ncl6) which you can change to one of the elements in the list (shift + writing a custom identifier won't work). This element will be used as order string.

You can use this order then in "Unit - Issue An Order..."-trigger actions. Pay attention to the correct targeting type. If you picked one of the order strings that is not listed there, you may choose another one or switch to jass functions. In jass, you also have to possibility to run orders via a numeric id instead of the string one. Not every spell has a string order but all active abilities have a numeric one.

Oh I see it, that was right infront of my face. Thanks for the fast reply + rep

you can modify an order string of all spells, they have the field
"Order Sting - Use/Turn on" and the string there is the one you use for triggers... anyway there is no constant in GUI that calls the channel spell so if you retain the order string of channel then you must use a custom script...

Base orderId of channel is used to enable you to use multiple channel based spells on one unit by just making them have different BaseOrderIds...

Okay so this is a late response as my campaign was corrupted and I had to rebuild from an older version, anyhow. The trigger I made for the npc to use the chain hook spell works fine, the only problem is that the chain hook spell can miss if the target is moving too fast. I tried changing the target type to unit target and the missle to homing etc, but I didn't think it'd work because the spell itself isn't the trigger. I"m unsure of how to modify the trigger so that it always hits.

U'd better ask the creator of the spell. Or analyze the trigger yourself. Or put the trigger here so people can see it and try to help you.
