Hi Ketoulou,
I have the same issue that you describe in your first post.
I tried your solution but does not work.
Construct version: Release 126 (64bits)
Steps:
1) Press Right arrow
2) Press Left arrow without release the Right key
3) Release Left without release the Right key
Then the player is going right but with the left animation.
How can fix this behavior?
