MUI Spell Problemo

[GodsHand]

until now ive never needed to use mui so i read a tutorial about it and it works...almost. I based it off of wyrmlords https://www.hiveworkshop.com/forums/trigger-gui-editor-tutorials-279/multi-instancible-gui-spell-making-34393/.

as you can see i changed some things to fit my needs (its basically a very simple bullet/shooting system). But it doesnt work. its flawless at first but something happens and all the bullets stop moving. Could anyone take a look please? i think 99% of it is bc i dont fully understand the stystem haha

Funny, wyrmlord is a really old friend of mine (I taught him JASS years ago now).

Its also funny how you're doing a bullet, which was one of my first multi-instance-able JASS scripts.

You also read an out-of-date tutorial on multi-instance-ability because GUI users now have access to hashtables, which basically allows you to reference "saved" values from handles. In this case, you would save your data to the timer and then reference it using the "expiring timer" in the periodic trigger.

I was going to try and post some triggers to show you how it works, but it seems like my hashtable GUI functions are broken or something. I usually code in vJass so this isn't a typical problem, but I'm having troubles obtaining the "key of a handle" for non-handle types. It won't allow me to use any other type of variable and a variable is the only option. When I try to set the value of the handle-variable before-hand it won't let me select any values other than another variable, which is of no use.

That's because of JNGP, it's outdated.

I figured as much.

This is how it would go with hashtables. Didn't test it though.

ohh ok well that makes sense thank you! + rep for all yay but i have another problem now...i cant find hashtables. i thought they come with one of the new patches but i dont have hashtables in my editor ): i know this is off topic now but could anyone explain that please?

 

[Maker]

Are you using normal Worl Editor and at least patch 1.24?

 

[GodsHand]

yeah the normal editor and the newest i guess current patch. idk if my frozen throne installed correctly so thats probaly it but its tft editor and everything.

Edit: hmm it looks like its bc tft didnt install correctly bc i cant open any war3x files including the .mpq which is the editor. and it says i only have patch 1.21 so it looks like im gonna find my cd and reinstall. hopefully thatll work. thanks for your help!

 

[Berb]

You can actually download the installer from blizzard's website if you have a CD Key for the game.

 

[GodsHand]

oh really? i actually think i saw something like that thanks!

 

[GodsHand]

hey! i just wanted to say thank you for everyones help, i got everything working again yay! thanks
