What am I doing wrong with 8Direction.MovingAngle?

I'm trying to do a small topdown thingy.

In it, I want my player to move a bit in the direction he is moving when he attacks.

To get the direction in which he is/was moving (with 8 movement behavior), I stock the Player.8direction.MovingAngle in a variable when he is moving (so it never returns to 0 except when it is the correct angle). This variable works.

After that, I use Custom Movement to move the player (if I simply use the "Move at Angle" or "Move Forward" action it only 'teleports' the object). I use the action "Accelerate towards Angle" and use the variable I used before.

And it doesn't work. I don't get why, sometimes it slightly change for a weird angle, but I really don't get where is the problem.

Here is the event:

And here is the capx:

Thanks a lot for your help!

You're enabling the Custom Movement Behaviour only after you have moved the player. The "Set Custom Movement Enabled" should be the first thing below "Set isAttacking to True".
