Solid platform problem

Hey,

I want to make a solid platform not perfectly straight ground that player moving on. The problem is when i put solid blokcs side by side they can block player moving. Is there any way to make curves surface?

Here is the screenshot how i do it now.

There's no real way to make curved collision, but the way you are doing it seems fine to me - can you upload a capx so we can see the issue?

Damn now i dont have capx in my computer but i can tell how its work. I make sprite box, pin the player animation sprite to this box and in events moving only sprite box. When i made a little altitude on sprite box path (just like on up screen) he stuck (not every time). Dont idea how to resolve this.
