How to stop the double jump and jumping from a parallel platform

Can some one help with this. I am setting up a world where the basic character has to jump on a platform.
Also I am using the jumping settings and want the character to jump only once to the above platform but player cannot jump with the consistent flappy syle bounce but a one push jump to each platform. So the character must jump through the platform and land on the top of it. I have tried several techniques but cant quite come up with a winner!

 

Hi
In the collide shape of your plateform you can select a side that you can go through.

 

so the character can jump through the platform and land on top?

 

Pls explain or show a screenshot

 

1- make the jump counter to 1 and the jump itself into high value depend in your gravity play with it
2- in the object collision editor press the one way collision it's an arrow in the the to top left

 

Thanks
