Hello.

I have the following problem:

We are currently learing C# in school (first year) and now we have to make a project (GAME PROGRAMMING).
Me and my friend decided to do something similar to Super Mario.

Our teacher provided us a self-programmed graphics dll which allows us to "draw" many things and move them etc..
Here's a picture how we want the things to be:

We don't know how to let that lines come from the right side. We only know how to let one come but if we want another one to come after 10 seconds for example we don't know how to program it.
We thought of parallel for-Loops but is that even possible?

Is there any other oppurtunity?
