United2d create one side collider

Question

I have a demo version of a card game.

I need a character that can jump through the collider on one side.

the collider in my character and land is as follows:

symbol: capsulecollider2d

earth: polygoncollider2d

so that the symbol can stand on the ground

can also jump to the ground

but now I want the symbol to jump from the bottom of the earth, it cannot work

So how can I solve this problem? Is there a configuration that can force the collider to have only one side?

Many thanks to everyone

thanks @EmreE @Jeroen De Clercq

I solved this problem using Platform Effector 2D provided by @EmreE

first: add a 2d effector platform to my land and select "use one way"

second: select "Used by effector"

now it works :)

Put your floor in a layer;
add your platforms to the layer;
When you jump, remove the collision with the platform level until you reach a direction that points to the floor.
When you press the Delete key, delete the collision with the platforms until you have completed one level of the platform.
