Why this does not work ???

There's an image in an attachent. I followed the tutorial on youtube, but anime.gettrigger does not work for me, but works for him, how do I solve this ?

Also I have created a parameter Jump and added it to an arrow for animation switch.

 

I don't know which tutorial you mean. In general, you should post the actual code here using code tags:

What I can see is that you didn't specify what "anim" actually is. You are not declaring it, but you are using it.

 

Oh tnx. I didn't watch all his previous videos in that tutorial, so I might be missing some variable or similar. I am going to watch them all. And I didn't watch previous videos because I just needed a specific thing from his videos.

Thanks though. If I still don't find a solution I will report here.

 

Tnx mate I found solution. It was answered in previous video of his in first 10 secs of the video.
