Double free of type: xecast

09-14-2008, 12:39 AM

>>Hi friends...leopard come here with the best regards and some question need your help

>>I have just complete converting from CS to XE, but every time a unit cast spells, i get this message: "double free of type: xecast"

>>Belows is an example, this idea is simple. Every 0.2 second, a lightning bolt will strike a random enemy unit for up to 6 times...Its fine, right?

>>An other problem...Here is my spell "Nature's Grasp" : Gives a chance to entangle enemy melee units that attack the unit under Nature's Grasp effect.
--I do this by: every time a unit attacked, attacked unit has buff Nature's Grasp...then gets a random int and if it meets..order the caster to entangle atacker...But...every time a unit is attacked, i must use :

JASS:

local xecast   xc  = xecast.createA()

..Will this leak and ineffective?
But local must be at the top..so i cant create it after the requirement meet..(15% chance for example)

Ok, the code, so you can help me out easily:

>>About

JASS:

local xecast   xc  = xecast.createA()

..The object will be destroyed automatically, right? but exactly when?

>>About spells use periodic time...for example "every 2 seconds, strike a target and after 10 seconds, stop it"...I have to use 2 timer? One for the periodic and one have a 10 seconds timeout to stop it? or there is another easy way?

>>I like Dusk, am i a gay ???

I could be very happy if someone could help me...thanks

Leopard	Anybody there? Are those issues so hard ???

Vestras	it's because you do this more than one time: call mystruct.destroy()

No (unless XE destroys stuff automatically) - can't really see what the problem is there... :-\
