Plane Doesnt Collide

hello, i’m really new on Unity and trying to make some easy and basic games. on lessons, i can’t see green area of plane. plane is my main character and it doesnt match each other, and it doesnt collide the platforms. how can i fix that, how can i move green area to my plane?

this is the picture of plane and green area;

For starters, you’re using old 2d methods. Unity 4.3 brought complete 2D features into Unity and I’d suggest watching their intro video at https://www.youtube.com/watch?v=4qE8cuHI93c to get an idea of what I mean. I’ve got some beginner learning stuff in my signature as well. Using the new 2D features would solve all your problems but you can also fix the project you’re working on by playing with your gameobject’s Z-axis values since you’re using a 3D setup. Keep your player and controller on the same z-axis value and you should be fine.

edit: here is another intro tutorial to showcase the new 2d stuff.
