Well I made a waling animation for one of my weapons in my game,but when I start walking,the idle animation keeps showing until it's over and than the walking animation starts.(the engine waits for the idle animation to stop and than shows the walking one)
I've uploaded a video of this in case you haven't understood me.
http://www.mediafire.com/?whuxdzw4nu4 Is it possible to make the weapon not to wait for the idle animation to stop,I want when you start walking the the waliking animation to show immediately.I know that I can make the idle animation shorter,but I want it to be long,so I need to make the weapon not to wait for the current animation to stop to show the next one

The link seems to be dead, but no doubt you have solved this problem by now.
