How to let a computer cast a spell until its finished?

[McPhisto2051]

hello everyone ,
I want a computer (player 21, I've tried neutral agressive before) to cast my customized death and deacay spell. This spell lasts 20 seconds. (I really want death and decay because of the % unit damage)
I tried using a magician and now im using a lonely tower to cast the spell.
The spell starts correctly for each caster but it always stops after approx. 3 seconds.
What am I missing?

My guess would be that it has an AI that starts another action. Try messing around with the AI editor.

I tried a little but without succes...
Any other tipps?

A moderately easy workaround would be to use a channel spell which disables other input while channeling (standard feature of the spell).
Then cast Death and Decay at the target area using a dummy unit or simulate the effect using triggers.

could you explain this in more detail please? or even make such a spell?
I've created a channel spell but cant cast it.

Before I do anything, please clarify the exact scenario that this spell is used in.
Is it an event, like a scripted bossfight, where this is used at a certain point, or is it just a spell that a computer enemy might cast at you in any given fight, in, say, a custom melee map?

Im happy to use as much gui as possible.
It will be an event in a boss fight.
The spell should be "death and decay" (because I need % health drain) with the visuals of blizzard.
It will be cast on a given point.
Im using an invisible tower who can cast the spell.
I hope thats all

Right... first off, to rule out an AI issue, have you tried changing the owner of the tower to Neutral Hostile? Assuming that this is not a major issue in some way.

 

[McPhisto2051]

It always was neutrale hostile and I tried player 21 to check for differences. There's none, both stop the spell at approximately 3 seconds.
If I cast the spell myself it works for the full 20 seconds.
If there's an AI problem is it possible to turn the whole AI off for some players?

You may wanna just simulate the spell using a special effect and a triggered damage event. That way, you don't even need a dummy unit casting in the first place.

but then I need the hated waits again which are for a 20 second spell up to 19...

This isn't going anywhere if you don't post your triggers or the AI scripts.

Try to order to the tower to cast it every 3 second it is a trick but I think it works

Attached an example map below. You have an ability that is based off of Breath of Fire which when cast will create a Dummy unit that is ordered to cast Death and Decay at the targeted point.

I assume the AI can't give orders to Locust (Dummy) units so I think this will work. If it doesn't you can always trigger it pretty easily.

Edit: Attached 2 maps. Death and Decay 1 is the Dummy version. Death and Decay 2 is a triggered version. Note that the triggered version isn't MUI and will bug out if you cast it again while it's already running.

hey Uncle,
many thanks to you!
I was very busy this week so I just got some time to check your maps.
Just finished map 1 and if I use the dummy Unit in my map and its spawned for me (player 1) it works perfectly fine but for player 21 or neutrale hostile it stops after 1 wave of blizzard...

Seems to be a bug of my map because in a new map it seems to work.
Has anybody an idea where to check or what to reset in the map settings?

 

[Uncle]

Was it an older map that is now running on the new patches? People seem to be having issues with older maps. Anyway, the triggered version might be your best bet until it gets fixed.

 

[McPhisto2051]

the map itself is over 10 years old and saved in 1.30.1

Other maps made in 1.30.1 seem to run smoothly.

 

[McPhisto2051]

I should have thinked earlier about it, but I can just use player 1 for casting the Death and Decay Spell. It works even if he isnt playing and thanks to uncle's dummy unit I dont need a hostile caster
Works fine even if red isnt playing.
