Animator conditions, no bool state selector.

But in all the tutorials it looks like that:

I’m using Unity 4.6.2f1 Trial on Windows 7, can someone explain this issue?

I had to check and then double check. I had actually set the parameter as trigger on accident! Twice!! (I was following the Survival Shooter Tutorial.) You’ll know it’s a bool if the checkbox is square, and if i’s a trigger it will be round.

Meat5000’s comment and this answer Can't select condition value in Animator Transition - Unity Answers led me to the solution.
