how to make an actor not slide when moving?

Clock

There is an old post about this topic, but after the update of the entire forum, non of the old posts can be found. So here is my problem. i use accelerate attribute for my character left and right movement, but it slides. then i try to use move attribute. there is something wrong with the combination of jump. when I holding the move and then press the jump, the character wont jump at all. all i want is my character doesnt slide when hes running, and he can jump left or right. How to do that? please help

PS: something wrong with the forum search....
