Help with making spells !!

[Kosire]

Hello, it's been a while. I'm now working extensivly on some Heroes for me and my friend's Hero Wars map we're making. I'm sure Ill need help for many many more spells. but for now, it's the first hero.
Spell: Apply Acid - For x seconds the hero's attacks slow enemy movement speed for x seconds by x%. I have the dummy spell made. I don't know how, or if I have to trigger this. If you could just give me some basic spell triggering tips it could prevent future noob posts as well ^_^

Edit: It gives a buff. Is there I way I can say to "have x effect while Hero has this buff" ?

You could just use slow poison.

Can I make this a "Buff" type thing? I dont want it to always be able to do this. only cast a buff on itself that gives the effect for x time

When they activate it, add them to a unit group and when they disactivate the ability, remove them from the unit group. Everytime a unit is attacked, check if its in the unit group and if it is, create a dummy and order it to cast cripple on the attacked unit.

How do I do like DotA does. make a "Buff Placer" that places a slowing buff on an enemy when they are attacked by a unit with the "Apply Acid" buff
Ntmention, I don't know how to use a dummy to cast

Try, instead of checking if the unit is in the unit group, checking if it has the specific buff then create the dummy ect.

To use dummies, create a unit based off a shade. Change its model file to .mdl and all of the shadow sections to none and 0. Then, give it the ability locust and remove all other abilities. Create a dummy ability for the shade which has the effects that you want your ability to have (In this case, slow) and give it 0 mana cost, o cooldown, no techtree requirements. Then, give this to the dummy unit it the OE. Then use this trigger:

Event: Unit is attacked
Conditions: (Attacking unit) has (YourBuff) equal to true
Actions: Create one (Dummy) for (Owner of (Attacking Unit)) at (position of (Attacking Unit))
Order (Last Created Unit) to (Human-Soreress-Slow) Target Unit of ability being cast
Add a 1 second generic expiration timer to (Last Created Unit)


This has a few location leaks but it works. Also, Human-Sorceress-Slow should be changed to whatever the base for your dummy's slow spell is.

It only has one location leak. You can fix it very easily though.

wont creating a dummy on every attack create alot of lag really fast because theres new units every attack there'll be lots of invisible units taking up space

 

[Joccaren]

It will only create a dummy when a unit with the buff attacks. This is likely how DotA did it as well. There is no way of giving a unit a buff other than with a spell. The expiration timer removes the unit once it is finished with so you won't have a million just lying around your map.
