[Spell] Spell that make a mine explose aumatically and leave flames on ground

[CTP]

Hello,
I'm trying to make a spell where a hero summon a mine, and after that, when an enemy units comes within 25 range of the mine, make it explose, dealing 10/sec to all units within 100 range of the point the mine exploded for 10 seconds.

Since the sapper mine is disbled (it appear to have only kaboom)

1. I modified Summon water elemental to summon a mine at hero place
2. The mine is set on the ground, but how to detect units entering range 25 ?

I heard you have to use aura, I make the mine to have an aura (range 25) that applies a MineProximityBuff to any units within range, but can't get a trigger that detect buff gain.

So my 1st question is How to trigger my mine explosion ?
Other question are How to trigger the one mine that detect proximity and not others
and last one is How to center the AOE effect to the position of the mine and not the triggerring unit that gain buff ?

For the damage over time effect, the easiest method is to create and order a Dummy unit to cast Flamestrike at the position of the mine when it dies.

• Events
• Unit - A unit dies
• Conditions
• Unit-type of (Triggering unit) Equal to Land Mine
• Actions
• --- Create dummy unit, add flamestrike to it, order it to cast flamestrike at the position of the (Triggering unit) ---

Check out my FIRST comment in this thread for more info about Dummy units:

Dummy Casting Problem

I made this trigger for a unit to automatically cast "anti magic shell". Anti magic shell Events Unit - A unit Begins channeling an ability Conditions And - All (Conditions) are true Conditions (Ability being cast) Equal to Dummy Heal...

How to create a dummy that can cast more than once

Unit Group - Pick every unit in ug and do (Actions) Loop - Actions Unit - Order unit2 to Night Elf Warden - Shadow Strike (Picked unit) * it will cast once. The dummy cast once and never go on, I think this is because it needs specific change to movemet type movement speed or turn...

Another example of Dummy unit usage:

How to set specific/random areas around targetted point of a spell?

I'm interested in learning how to make my spells cooler. Let's take Flame Strike for example, how would one go about making it so there is additional explosions to the left or right of that initial target? Or what if I wanted two more strikes placed randomly around the target?

If Flamestrike doesn't work for you then you'll have to trigger a custom periodic damage over time effect yourself. This could help you get started:

[Trigger] - Deal AoE damage per second trigger with waits. Is this spell MUI?

This trigger doesn't work properly, when units are inside AoE range they take damage, but if they go out and come back to it they are not affected. Did I miss out on something? Smoke Events Unit - A unit Starts the effect of an ability Conditions (Ability being cast)...

The Dynamic Indexing method comes to mind as well (link in my signature), that's what I'd use to trigger this type of effect.

Spawning an invisible, locusted dummy unit also works. Give it permanent immolation and an expiration timer.

But it sounds like the issue is knowing when the mine is tripped in the first place. That's what the Goblin Land Mine item abilty Lordul Dracula referred to is for (and how Uncle showed it being used).
