Hello. here is my code for Inertia, but there is something strange when I go from Left to Right. It stays a while on vx 0 but not from Right to Left. Why?

I think I found my issue.  
mySprite.vx \<= 0.5 && mySprite.vx \> 0 || mySprite.vx \>= -0.5 && mySprite.vx \< 0 I forgot about negatives values
