getting the same issue
1. add event -> keyboard x is down set animation to xxxxx // expected changes animation
2. test works changes animation // as expected animation changed
3. changing keyboard x to on pressed x set animation to xxxxx // expected changes animation
4. test: Failed: animation is not changed to xxxxx // nothing happens
5. changing keyboard x to on pressed x play sound xxxxx // expected sound is played
6. test: sucess!: sound is played! // as expected sound is played
so it seems there is some thing wrong with the "on pressed" it does not trigger animations, but sounds do work ..
