Hi.
I looked back the the video again.
the Next Frame event, does it send the 'loop' transition?
if so it should be on the bottom of the list.
but also i noticed the the other actions have every frame active.
if a action is set every frame it will stay in that state and run every frame.
So you do not need 'next frame event' there
OR
Turn off every frame on the other actions, place next frame in the bottom of the action list and you can also set as sequence. (right Click in state window to toggle Sequence)
A state always executes the top action 1st, then the next and so on.
If sequence is turned off, it will not wait until previous Action is finished.
If sequence is turned on it will execute and wait till finished and then go to the next action.
