Advanced scrolling for vertical shooter game

This forum is currently in read-only mode.
  • Hi guys!

    I'm wondering how to make an advanced for vertical shooter more like aero fighters.

    I uploaded a picture that explains what i mean:

    (Note: It starts from below to above)

    <img src="http://i.imgur.com/oWWIb.png" border="0" />

    is pretty simple, no?

    Can you help me?

    my regards.

  • test 'scrolly' (the y scroll position) so that when it reaches the point in your level where the scrolling is supposed to stop, it sets a variable "miniboss" to 1, which makes it so that the miniboss backgroud starts looping, the main scrolling stops, and the boss starts. Then when the boss dies set miniboss to 0, which means the scrolling continues.

  • Thanks for reply.

    Actually, i have a problem with "ScrollY" it goes to wrong position at order of editor, i have no big experience about this scroll. I wasted some hours how to resolve the correct position before the scroll starts.

    I uploaded a .cap if you can see it

  • I downloaded your cap, but there's too much going on. Noone but you knows the concept, so I can't say what exactly you are trying to achieve. Could you please do a simple example cap with an explanation where exactly it does not work as intended?

    About ScrollX and ScrollY: They return the center point of the current view. If you don't scroll your layout, then those values never change.

    Example1:

    Window size 640x480, layout size 640x480

    ScrollX, ScrollY will always return 320, 240

    Example2:

    Window size 640x480, layout size 800x600

    ScrollX, ScrollY will return 320, 240

    If you now scroll your layout, using System: Scroll to X 420 then

    ScrollX, ScrollY will return 420, 240

    I made an another simple example cap... well i'm not sure about your methods, i tried to experiment with another methods and it works!

    What do you think about this method? I'm unaware about layout editor may support to fit the 3000 height sprite or 800 height separated sprites at vertical align...

    Actually, i had no idea how to make it when the boss appears should to stop vertical scrolling except a tilemap with animated offset (If you saw my first post). Until The boss dies and the continue vertical scrolling.

    Do you think can you help?

    Sorry, my english is not native language, i hope you understand.

    Thanks!

  • The cap below shows just one way of doing it.

    And never use 1 huge texture to form your game world. Compose it out of several tb, sprites, etc.

    For example, in a real game, I wouldn't use just one tb for the map's surface, but use several sprites for the houses, streets, trees, whatever and apply the same technique as shown in this example.

    But before you go on, make sure you are familiar with all the basics of CC. Use a tutorial that comes close to your game idea, consult the wiki, try some behaviors.

    Good luck :)

  • Awesome! i tought i had no reply on this thread, but i was searching my threads to check my old threads and i found your surprise reply!

    Ok, i will not use a huge texture... maybe i will do for different tiled backgrounds each scene.

    I will continue my project with your method.

    Thank you a lot! :D
