After several tests, I understood that the curves lerp was the problem … If the last point of the curve is equal to the length, so it creates a lag with the full accomplishment of the movement because each time, from 0.1 the curve is not fulfilled … (regardless of the length: 0.15 to 0.14 for the rotation and last point, works very well)
In fact, I think the gate was not working because it was a lag of rotation, while the gate works perfectly !!!
This also caused collisions problems …
I still have two problems:
1 major: The character does not fall as the buttons are pressed …
1 minor: When collision sound is played several times at the same time …
Thank you
