How do I use the physics forces for movement?

Hello,

I have a sphere (player) what is bouncing always by physics. I want to control it with left and right arrow. It's working when I go to right with this:

right arrow is down

• Apply Physics force (force X + 1)

I can set the maximum "speed" by this:

Player; compare velocity on X; greater than 150

• Apply physics force (force X - 1)

It's working properly, but when I use it with left movement (I tried to use opposite values) it's happened something weird. I'm almost sure that the problem is:

left arrow is down

• apply physics force (force -1)

. The "-1" value not working well but I have no more idea how can I use this force to left movement.

I use a variable to separate the left and right movement, so the program makes a distinction between these two side.

Thanks!

Just use "Apply force at angle".

Use 0 for movement to the right and 180 for movement to the left.
