How do I make character only jump

I started to create a android game, but my character, with 0 max speed keeps moving back and forward.

He only needs to jump. Please help.

Bug fixed: I created a script, to make ground move to left, the character follows it, this is the bug

No, all you have to do is don't make any onscreen buttons to move your hero left and right. You can move your character back and forth on computer, but on android the only controls that exist are the one's you make. Having the ground move below the character just uses up memory.

As PixelPower points out, all you need is this:

If you dont want the Default Controls for left and right, set that property to 'no', and create your own keys.

You have to anywayz on mobile.

THX!
