[Trigger] Hookshot Crash

[Rufus]

[SOLVED] Hookshot Crash

Is there something wrong with this?
It works perfectly for me, but two Hivers who tested it reported crashes assosiated with this trigger.

The ability fires a hookshot in casters facing direction, and pulls in small (Summoned) units and pulls the caster to all other targets.

Here you can find a test map with the trigger:

Works fine for me. On the other hand, I did encounter a bug with it when I aimed it at the castle. The hook pulled me into the center of the castle and I was stuck had to restart the map.

 

[Rufus]

Ah, yes!
Well I had that "bug" too, but it won't be a problem later since I won't have large buildings in my map. It was a bad example putting it there.
Although, you don't have to restart the map, you can simply use "Rewind" to get out of there as it targets the closest walkable location.

But no troubles for you?
So far 2 no crash, 2 crash... :|

Thanks!

 

[KILLCIDE]

You should ask the two people that crashed where they were and where the hook landed (if it did) when the crash happened. I ran around the little island for a good 10 minutes just spamming it without a problem.

 

[Rufus]

Yeah, they said it crashed a little before reaching max range, so that means the problem has to be in that first trigger.

I am using a custom lightning effect (.slk), but that shouldn't be a problem... :/

What did you think of the abilities in general?

 

[KILLCIDE]

The only "crash-worthy" script I see in your triggers is the Destroy Lightning function. From what I can remember, destroying a null lightning has crashed maps in the past.

What did you think of the abilities in general?

I'll play around with them and make a post in your original thread.

 

[Rufus]

From what I can remember, destroying a null lightning has crashed maps in the past.

Ah, ok!
How can I go around this?
Would moving the lightnings starting and ending location to a cornor of the map (out of sight) instead of removing it help?

 

[KILLCIDE]

Ermm since you refer to bj_lastCreatedLightning when you destroy the lightning, I would just make sure that you actually have an active lightning effect. That was just a minor suggestion though, I could be remembering the whole "destroying a null lightning" issue wrong. I would need more details on their crash before actually coming up with a conclusion.

 

[Rufus]

Ok, I read some threads about it, and it seems you are right.
Destroying Null Lightnings almost always causes crashes, so you have to change or nullify their variable before destroying.

I fixed it my way though.
I do not remove the lightning at all, as it is not needed. I just make it invisible instead.
The trigger got slightly smaller and it matches the animation a little bit better.

I'm gonna contact the users that got crashes and see if it is fixed.

Thanks for your help!
