Hey how do you do this

hey...how do you make a game similar to linerider.com

*Sigh* One liners now. Tell me if you manage this one. At the moment it is not really possible, DO-able maybe but really need to finish the dynamics object for this to be do-able so.. answer at the moment is NO. You can make ski type games but not exacly like this one. See the sonic examples.

It is not that easy... I think it's not even possible. Why don't you first check the tutorials arrived with the MMF2 disc. A lot of people come here and ask something like "How can I make an MMORPG?"
You should really work more with MMF first. Try building a space invanders game or something first.

what about a game like bubble-struggle.com ?

Bubble struggle is a bit more realistic. If you're new to MMF, i would suggest using the pre-made platform movement and bouncing ball movement to get started. Then if you want to make it a bit more like bubble struggle people can tell you how to make the "realistic" bouncing movement.

But i really don't recommend getting inspiration from flash games, as these are completely different and will more often than not be impossible to make in MMF.

In regards to linerider... It is possible, just hard.

Here is how I would go about it:

When you are drawing the line, where you would normally interpolate between the two points (You store the old mouse position and the new one) you would also store the new point in some kind of an array.

Now when you have your object you need to perform a circle/line intersection test to determine if there has been a collision.

Then you would handle collision response by finding the vector between the two points that make up the line we just found a collision with. Calculate the normal of that vector, and that is the vector that needs to push on the object to make it so it doesn't fall through the floor.

Now it might be necessary to project the object at the vector between the two points also, I am not rally sure.

If this makes sense to you, then good job :). You are somewhat closer to making this game :D.

Alternatively, you could have a selection of various different "parts" the player could put down (different angled lines) and the player could put together a track out of that.

well you see on the opening page when yo enter you have that text and you click continue and you have all those buttons at the top. how do you get that text the way they have it with the continue button. as well as all those play stop save buttons etc...

that's not very complicated. You could just use Active System boxes... Really the interface is the least of your concerns ;).

how do you make it so when you click a button it does a certain thing....?
