Siege Fire Blast Ability

[UmbraUnda]

Need help figuring out how to make a fire blast ability for catapult, ballista, and infantry (molotov cocktail).

I want it to use aspects of Orb of Destruction and Burning Oil (or maybe there's a better ability to use?).
Ideally, unit uses ability, targets area - attacks - upon impact, explodes and leaves the burning oil effect.

Appreciate any help and advice.

you could maybe use a modified Flame Strike, it does almost exactly what you want

Good idea - just tried it though and I couldn't get the missile to appear. Any other ideas?

Well if you have the Sphere ability on the unit, it should shoot a projectile (that's what the Blood Mage does in the base game). The projectile arc might not be to your taste though.

An alternative is just using Acid Bomb, though that requires a unit target.

A ground targeted grenade type ability will probably require full triggering. The easiest way to go about it would be to spawn a dummy unit at the caster location that attacks ground at the targeted point. Burning Oil (iirc; the demolisher ability) will leave fire on the ground like you want.

You could use a dummy caster for the flamestrike and create your projectile with another ability

The unit shoots projectiles already, although for flamestrike when I tried adding missile art, nothing happened. Indeed the arc is nowhere near realistic for a catapult.
Acid Bomb is decent, still not exactly what I'm trying to do though.
Ayy full triggering? Any idea of how that would be done?

Interesting, how do I do that?

Missile art won't work on flame strike indeed.

Create a dummy, move the dummy until it reaches the target point, kill it, cast flame strike on it. However, you'll need parabola equation to make it arc. I'd suggest missile arc system (you can find it in the spell section), you can then modify it to your liking.

Hmm I'll try my best to do that with GUI triggers + implement that system. I'll let you know how it goes later. Thanks for the feedback!

I'm not sure about the orb of destruction part, but in order for burning oil to work you have to change the weapon type field to artillery, took me a very long time to figure this out

Doesn't the catapult weapon already has AOE damage build in? You can give it a blast effect, make it look good that way and just use burning oil, unless there's something Im not understanding about your post, this is all you really need.

It's not that simple. The issue is that I want this fire ability to be separate from a regular attack. Burning Oil works for all attacks - I want it to work only for the ability.

Any ideas ?

How about to create a dummy unit with artillery attack and burning oil ability?

Simply spawn it and order it to attack-ground the targeted point upon cast

That's the thing I used for my dragons (apart from burning oil which by the way would be a good idea)

Spoiler

Edit: Nope, it laggs as hell with burning oil on

 

[Lord Aiden]

If you want it for a special ability you can create a dummy unit at the location which has burning oil, is trigger to use it on the spot and has a short expiration timer,

event - unit casts an ability
condition - ability equals to (whatever the name is)
create dummy unit with burning oil at location of ability being cast
make the dummy unit have an expiration timer of like 1 to 1.5 sec ------(make sure the dummy is flying, has a collision size of 0, no model, invulnerability, and the ghost ability, and burning oil)
trigger the dummy to attack the point where the ability was cast, that way it can do AOE damage + burning oil effect

Nice - thanks for the descriptive trigger sample. I'll let you know how it goes soon.
