Frame Transition Like in Knytt

[Jale]

Well this is mainly aimed at Nifflas, but if anyone else knows thats cool.

Basically in Knytt one of Nifflas's games there is some pretty smooth frame transitioning, im just wondering how this is acheived as i would like to do something similar in my current project.

Thanks

Knytt actually doesn't have frames, the reasons are obvious if you think that there would have to be hundreds of separate frames. The smooth frame transitioning is just repositioning of the camera object.

Yea thats what i thought, but how is this acheived?

You could do something with a camera object and a player object.

The camera object would be at the top left corner of the screen, and so you would center the scrolling window at Camera X + Frame Width / 2, and Camera Y + Frame Height / 2

Then the events would be something like:

Player X is less than Camera X
- Set Camera X to Camera X - Frame Width

Player X is greater than Camera X + Frame Width
- Set Camera x to Camera X + Frame Width

Player Y is less than Camera Y
- Set Camera Y to Camera Y - Frame Height

Player Y is greater than Camera Y + Frame Height
- Set Camera Y to Camera Y + Frame Height

I have no idea if that works as I kind of made it up as I went along, but maybe it's something like that.

I believe he posted a movement example somewhere for the bouncing ball movement of Within A Deep Forest, and it used the same camera angle system. There are plenty of ways to do this though.

---EDIT---
Found it!. There is only one event in the group scrolling, that is the one you need. http://www.clickteam.com/epicenter/ubbthreads.php?ubb=showflat&Board=5&Number=41356&S earchpage=1&Main=6294&Words=within+a+deep+forest&t opic=0&Search=true#Post41356
