It is normal that we can't use every tick event? what happens if we need to do it??
thanks for the help

Technically, the Every tick condition just means 'true'. The way events work is that they run the actions if every condition is true. Therefore, adding Every tick to an event with other conditions has no effect.
There is also nice explanation on start of this article: scirra.com/tutorials/292/guide-to-construct-2s-advanced-event-features
So short answer would be , that every function is checked and checked even without `every tick`.. - so if we need things to play just ONCE we add TRIGGER ONCE
