Guys, I’m very new to UE4, I’ve been trying to make a 3D side scroller game test just to check how everything works out. I created a blank project and followed UE4 Introduction to Third Person Blueprint game to do the input and character controllers and stuff. I manage to make the character idle/walk/run, jump and some basic items pick up. However, there is a problem with the jump, it doesn’t jump in one axis (Y axis), the walk/run move in Y axis tho.
Here is the link of the game test: - YouTube
If you look at where the character stands at the start, it should be in the the middle of the ground according the grid of the ground. However, you will see in the video, after the character jump and it doesnt land in the middle of the ground any more (it doesnt happen with every jump tho, sometimes it lands in the middle of the ground, but sometime doesnt), therefore, the character cant pick up items. D: How do I set my character to jump in one axis?

Here is a screen shot of MyCharacter component http://i.imgur.com/xwLVySD.jpg
the second problem is: I press left or right to control my character to go left or right and it faces to the correct direction. However, when I let go of left key, the character faces to right automatically. If you take a look at my character component screen shot, I changed Yaw in Rotation Rate and Orient Rotation to Movement so my character doesnt run backward when I press left key. Before I did this, my character ran backward if I press left key. 
I just want my character walk/run/jump like the 3D side scroller template character does. D:
I’ve been following these tutorials and used in my game test. Just give you an idea what I did to my game.
