explosive arrow

[Herod]

Hi, How can i make a explosive arrow spell. With area damage and "burning oil" effect?

With a projectile system would be the easiest way, then you pick all units within X range of the projectile if it hits a target and damage all picked units. Then create a special effect on impact.

Or make a dummy auto-cast ability. When it is turned on auto-cast, add a hidden Burning Oil ability to the unit. When it is taken off auto-cast, remove Burning Oil.

I uploaded a map with what I believe you wanted. It's a fully configurable projectile that will explode upon contact with an enemy. Upon exploding I have a Dummy unit cast Flame Strike in the area creating the "burning oil" damage over time effect.

The triggers will be confusing to newer users but I did the best I could to keep it simple while also being configurable. If this is too much then maybe try searching for a Projectile System that already exists on here and try to use that instead.

I used Dynamic Indexing to make the spell MUI, which means multiple units can cast the spell at the same time without any problems. There's a link to Dynamic Indexing in my signature. If you want to use this in your map then make sure to Import the Dummy unit, Both Abilities, and the Buff, before importing the triggers. Also make sure to set "Automatically create unknown variables while pasting trigger data" in the editor's File/Preferences if you haven't already. Do that before importing the triggers!
