Chain Frost Spell Problem

[Igor_Z]

I got a problem with the triggers for the Chain Frost spell. Can you tell me what is wrong with them. When my hero casts the spell it instantly kills the Bouncing Glaive which means there is something wrong with the second if/then/else action in my second trigger. Thank you for your time

The problem might come from the fact that you're using globals and they could get overwritten. I read the triggers trough and didn't find anything unlogical. Why don't you try storing the values which you take from trigger to trigger in a hashtable?

 

[Igor_Z]

Don't know how to use hashtables ...

 

[feelingparty]

Well hashtables have proved really handy to me and I strongly recommend you to learn how to use them if you want to create MUI spells in GUI. Here's a link for a good tutorial:

[Igor_Z]

Nevermind the hashtables. Don't want MUI, don't need MUI. I can't figure out a way to fix this

There may be something wrong with the conditions in the set unit group action, but I can't tell because you cut out some of the conditions. Use in-game text to display the values of the variables in your "or" conditions and see which variable isn't getting the right value, then fix it.

Edit: I think I see the problem. You don't add the target unit to the unit group you use to check which targets are in range, so the unit group starts out at 0. If the initial casting distance is greater than 50, then the trigger will not attempt to find any available targets either. With other words, "BG_Num_of_Units" is most likely always 0 and therefore your dummy unit is killed instantaneously. That's just a guess though.

 

[Igor_Z]

Yeah. You got a point there. That is true. When I remove the BG_Num_of_Units variable the spell works perfectly(but hits same units also) but I want the trigger to check whether there are targets that haven't been hit... It's not that much of a problem but I want the spell to run like that. What do you suggest me to do? I wanna fix this as soon as possible. I'll play with the trigger a bit and see if I can make it work
