[quote:3cxlcdf8]So in other words I will have to scrap the idea of using families and create events for all of these separately? (or at least the weapons like the holy water)
No, the reason is you mix you objects up, you spawn an object of holy water, and you test against a family object, which is fine.
However here is where it goes wrong.
You check if the weapon is 3, which it is, then it spawns the fire and then destroy holywater. But you haven't picked a holywater object, but a family object. So when you use destroy holywater, it destroy ALL holywaters, including the one in the air. To fix it, just change it to the family object. (Same with the spawn, it spawns fire for all holy water objects as well)
That will work as well.
I tried that already and all it does is cause the game to lock up or run very very slowly.
It doesn't do it on every throw but if you do it enough times it will do it eventually, though it does fix the problem it just creates another. Unless I am misunderstanding what you are says. I switched the holy waters that you pictured to the "subweapon" family.
